The slope of the inclined screen is fixed, although the stroke can be adjusted to the required level. The general working stroke of an inclined screen is between 8 and 12 mm, and design of inclined screens permits changes to this stroke through the addition or removal of additional eccentric masses on the exciter

The exciters of inclined screens are generally driven by an external electric motor that transmits the power via a belt and pulley mechanism. Vibromotor applications are not preferred for inclined screens due to their fixed condition working principle

Inclined screens are generally designed with multi deck arrangements, which allows material to be classified the between 2–5 grade types. Additionally, these screens are generally fitted with an impact area directly before the screening section begins that breaks up the material and causes any long pieces to lie flat during screening

Inclined screens are comprised of eight basic components, being the side walls, decks, screening media, exciter, electric motor, motor console, spring and spring supports. The most critical factor in inclined screens is their weld-free design. All of the parts mentioned here are assembled with bolt and nut connections to prevent the cracking and failure to the screen body associated with welding.

A horizontal screen is a non-conventional design that has unique properties that differentiate it from other types of conventional screen. Its most obvious advantage is its working angle. While conventional screens work at an angle of between 15° and 30°, horizontal screens work in parallel to the ground, or at a slight incline of between 0° and 5° degrees.

Horizontal screens are equipped with triple drive mechanisms that produce an elliptical vibration motion at the required stroke and slope. As mentioned at the exciter mechanism section above, the triple drive mechanism combines the linear and circular vibration types in elliptic vibration. In this way, the advantages of both vibration types are combined in a horizontal screen, so that while the material is being transporting horizontally at a determined velocity through the linear vibration motion, plunging is prevented due to the circular vibration characteristic of the elliptical motion.

The stroke of horizontal screens may be adjusted in a range of 14–20mm, although they generally operate with a stroke of between 16 and 18 mm and with a 750 rpm rotational speed. The material flow rate in the screening media varies between 0.2 m/s and 0.25 m/s. The mass flow rate depends on the differences of the phase angle between the eccentric masses

The triple drive mechanism is driven by an electric motor, with power transmitted by a belt and pulley mechanism. There is a possibility that the belt may come away itself during operation as a result of the high stroke working conditions associated with horizontal screens. A new belt stretching mechanism has been designed to overcome this problem, and all the power transmitting mechanisms in horizontal screens have been equipped with belt stretching mechanisms.

Horizontal screens have brought many advantages to screening operations, although there are some disadvantages, the most critical being the complexity of the triple drive mechanism. In fact, triple drive mechanisms have a sufficiently robust design to overcome any condition, however maintenance procedures are not short, although the robustness of the design means that frequent maintenance is unnecessary.

Banana or multi-slope screens are capable of achieving exceptional throughput per screening area. These screens have high capacity, low bed depth and high velocity, and may include any number of deck slopes, from two to as many as six, varying from 45º through to horizontal on the final slope.

Banana screens are excited by a vibromotor located on the top of the screen. As mentioned, the exciter section of banana screens has a segmented deck structure, causing the linear motion created by the vibromotor to accelerate the material differently at each deck surface due to the geometry of the screen, ensuring effective screen operation is achieved.

The feed section (highly inclined) of a banana screen permits high velocity material flow, which serves for the quick removal of fine material. Midway along the banana screen, the resultant thinner bed stratifies quickly, and the remaining fine material (below the cut point) is screened out more effectively than would be possible with a slower and thicker bed. The lower screen slope (see diagram) slows the material down, allowing more efficient screening of near size material at this point. The advantage of this is the quicker stratification provided due to the high velocity imparted by the banana screen shape

The various slopes may also incorporate deck media with different apertures to meet the particular processing requirements. The screens are commonly designed to fit modular rubber or polyurethane deck panels, although woven wire or punched plates may also be used, depending on requirements

De-watering screens have been designed to allow the drainage of slurry material water and to reduce the moisture rate of the material. These systems comprise a vibromotor pair, a vibromotor console, screening media and a screen body. The screen surface is slightly inclined (between 0° and 5°) to facilitate drainage and the working speed is between 1000–1500 RPM.

The counter-rotated vibromotors create a linear vibration that causes the screen body to shake together with slurry material. The water from the slurry materials is drained under the effect of vibration and flows through bottom side of the screening surface as the material moves forward. In this way, a pool of water forms in the valley as sand builds up on the inclined surface. The uphill slope of the screen along with a discharge weir creates a deep bed that acts as a filter medium, allowing the retention of material much finer than the screen openings

Different to dry material screens, dewatering screens work at G-forces in excess of “5g”, ensuring a perfect drainage operation. Generally operating within a range of 5g and 6g this pre-condition is necessary for a good dewatering operation

The fabricated vibromotor console frame, as a vital component in vibration transmission, is stress relived due to the high G-force working conditions. The screen side plate and the vibromotor side plates of the console must be machined to exacting tolerances to ensure a precise fit, and consequently, a long operating life. The steel frame should be constructed with bolted connections to avoid the cracking associated with weld failures.

Due to the wet and corrosive environment of the dewatering screen, rubber springs should be used on the support legs to absorb the live frame vibrating loads, which will extend screen life and maintenance periods.

High-frequency screens are engineered to provide higher production capacities and more efficient sizing than conventional screens. High-frequency screens operate with aggressive vibration applied directly to the screen, which allows for the highest capacity in the market for the removal of fine material, as well as chip sizing, dry-manufactured sand and more.1

Different to other type screens, the vibromotors of high-frequency screens are mounted on each deck instead of on the screen body. Aggressive vibration is applied within a range of 3600–5000 RPM directly to the screen media, allowing for higher capacity and more efficient sizing when compared with conventional screens. Under the effect of high-frequency vibration, a smaller bed depth is obtained, which allows for stratification and greater screening efficiency

The high-frequency and low-amplitude operation ensure a faster material travel speed without loss of screening efficiency. This combination of high frequency and know amplitude is ideal for fine material screening, in which coarse material particles are lifted higher while the finer particles stay closer to screen, and as a result, the probability of separation is increased with high-frequency screens

Very coarse materials are usually screened using an inclined screen called a grizzly screen. Grizzlies are characterized by parallel steel bars or rails set at a fixed distance apart and installed in line with the flow of the material. The gap between the grizzly bars is usually greater than 50 mm, and can be as large as 300 mm, with a feed size of up to 1 m. Vibrating grizzlies are usually inclined at an angle of around 20° and have a circular or linear throw mechanism

The bars are typically made from wear-resistant manganese steel and are usually tapered to create gaps that become wider towards the discharge end of the screen to prevent material from wedging between the bars. Grizzly screens generally used as a feeder prior to the crusher to supply the flow of correct-sized material through the crusher

Designed to convey material while separating fines, Vibrating Feeders utilize smooth, controlled feed rates to maximize capacity. The grizzly bars are tapered to self-relieve, and feature adjustable spacing for bypass sizing. The feeder construction includes a heavy-duty deck plate with optional AR plate liners, while the heavy-duty spring suspension withstands loading impact and assists vibration

According to different structure and use, vibrating screens usually be devided into many types by the vibrating screen manufacturers. Below wil introduce the top 10 vibrating screens, and how to choose the right vibratory screen?

linear vibrating screen is driven by double vibrating motors. When the two vibrating motors are rotating synchronously and reversely, the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor, and overlaps into a resultant force in the direction perpendicular to the axis of the motor, so the motion track of the linear vibrating screen machine is a straight line

Working Principle: The two motor axes of the linear vibrating screen have an angle of inclination in the vertical direction relative to the screen panel. Under the combined force of the exciting force and the self gravity of the material, the material is thrown on the screen surface to jump or move forward in a straight line. Through the multi-layer screen panels, a variety of specifications of materials are generated, and discharged from their respective outlets, so as to achieve screening and classification. linear vibrating screen is suitable for screening various dry powder or granular materials with particle size of 0.074-5mm, moisture content <7%, and no viscosity. The feed particle size is not more than 10 mm

Circular vibrating screen is a new type of vibrating screen with multi-layer screen and high efficiency. According to the type of materials and the requirements of users, the high manganese steel woven screen, punched screen plate and rubber screen plate can be used. The circular vibrating screen is installed in the seat type. The adjustment of the screen surface angle can be realized by changing the position and height of the spring support

Working Principle: The motion track of the screen box of the circular vibrating screen is circular. The circular vibrating screen uses the inertia exciter to produce vibration. The main shaft fixed on the screen box is driven by the motor to rotate at high speed, and the eccentric body installed on the main shaft rotates with it, generating centrifugal inertia force, so that the screen box that can freely vibrate will produce vibration similar to the circular track

Circular vibrating screen is widely used in the materials classification of mining, building materials, transportation, energy, chemical industry and other industries because of its long flowing line and many screening specifications

Elliptical vibrating screen is a vibrating screen with elliptical motion track (Elliptical Shale Shaker), which has the advantages of high efficiency, high screening accuracy and wide range of application. Compared with the ordinary sieve machine of the same specification, it has larger processing capacity and higher screening efficiency

Triaxial elliptical vibrating screen is widely used for the screening operation of sand and stone materials in sand plant. It is the ideal screening equipment for all kinds of mines, quarries and mobile screening stations

Working Principle: The power is transmitted from the motor to the main shaft of the exciter and the gear vibrator (speed ratio is 1) through the V-belt, so that the three shafts can rotate at the same speed and generate the exciting force. The exciter is connected with the high-strength bolts of the screen box, resulting in elliptical movement

Materials on the screens do high-speed elliptical movement along with the screen machine, so as to achieve uickly separate, sift and move forward, and ultimately complete the classification of materials

The working surface of the roller screen is composed of a series of rolling shafts that arranged horizontally, on which there are many screen plates. When working, the fine material passes through the gap between the roller or screen plate, large blocks of materials are driven by rollers, moving to the ends and discharging from the outlets. Roller screens are mostly used in the traditional coal industry

Working Principle: For the rolling shafts are arranged according to different working angles, the speed of the material is faster when it runs in the position with higher working angle; the speed of the material is slower when it runs in the position with lower working angle

When two kinds of materials running at different speeds converge at a certain position on the screen surface, they start to move axially, so that the materials are evenly distributed on the screen surface, and the screening efficiency is improved

Rotary vibrating screen is mainly used for the classification of materials with high screening efficiency and fine screening accuracy. Fully closed structure, no flying powder, no leakage of liquid, no blocking of mesh, automatic discharge, no material storage in the machine, no dead angle of grid structure, increased screen area

Any particle, powder and mucus can be screened within a certain range. Sieve to 500 mesh or 0.028mm, filter to 5 microns minimum. It can be used for classification, classification and filtration in food, chemical, metal, mining and other industries

With the help of the heavy hammer installed at the upper and lower ends of the motor shaft, the rotary motion of the motor is transformed into a horizontal, vertical and inclined three-dimensional motion, which is then transmitted to the screen surface to make the material do an outward involute motion on the screen surface. Working Principle: After the rotary screen is started, the eccentric blocks of different phases at the upper and lower ends of the vibrating motor generate a composite inertia force, which forces the vibrating body of the rotary screen machine to rotate again and again, and the screen frame continuously moves to and fro under the action of the vibration force, and then drives the screen surface to vibrate periodically, so that the materials on the screen surface move in a positive and directional manner together with the screen box. Materials smaller than the screen meshes fall to the lower layer, and the materials larger than the screen meshes discharged from the discharge port

High frequency vibrating screen is also called high frequency screen for short. High frequency vibrating screen (high frequency screen) is composed of exciter, pulp distributor, screen frame, supporting, suspension spring and screen, etc. High frequency vibrating screen is the most important screening machine in mineral processing industry, which is suitable for completely wet or dry raw materials

Working Principle: Different from ordinary screening equipments, high frequency screen adopts high frequency, which destroys the tension on the pulp surface and makes the fine materials vibrate at high speed on the screen, accelerates the separation of useful minerals with large density (specific gravity), and increases the probability of contact between the materials with smaller than the separated particle size and the screen holes

As a result, high frequency screen results in a better separation conditions, which makes the materials that smaller than the separation size (especially with larger specific gravity), and pulp pass through the screen holes together to complete the screening. High-frequency vibrating screen is usually operated at an inclined angle 0°-25°, up to 45°, and the operating frequency range is 1500-7200r/m

Grizzly screen has simple and solid structure, no power consumption, no moving parts, low equipment cost and convenient maintenance, but the productivity is low, the screening efficiency is not high, generally 50% – 60%, and the mesh is easy to be blocked

Working Principle: Generally, the grizzly screen is placed in an inclined position, and the materials are dumped at the high end. Under the action of its own weight, it slides down the screen surface, and the particles smaller than the gap or hole on the screen surface pass through the screen to achieve classification

Banana screen is mainly suitable for the classification of large and medium-sized materials with high content of fine particles, and it can also be used for dehydration, demineralization and desliming

construction, working and maintenance ofelectric

Working Principle: During operation, the motor is connected with the vibration exciter through the V-belt or soft connection. The motor drives the eccentric shaft to rotate to generate centrifugal inertia force, which forces the screen box to vibrate. After the materials fall into the screen from the feeding inlet, they move forward rapidly under the action of the vibration force, loosely and pass through the screen.The thickness of the material layer of banana screen from the feeding inlet to the discharging outlet is constant. The ratio of the material quantity to the flow speed on the screen of each section is stable, the material layer is high and uniform. The screening efficiency of banana screen is higher, which is 1-2 times higher than that of other screening machines with the same effective area

Heavy inclined screen can be applied to the treatment of debris from quarry, mine and building demolition, the treatment of topsoil, the recycling of construction materials, the screening of gravel, and the screening of gravel and aggregates

Working Principle: The screen box shaft is driven by the motor installed on the auxiliary frame through three V-belts, the auxiliary frame is rigidly connected with the machine underframe, and the screen box spring is used to support the screen box.Inclined screen usually adopts 2-4-layer screen panels, and is fixed on the inclined frame at an angle between 15° and 30°. The material can be screened into 3-5 grades at the same time

Horizontal screen has the advantages of both inclined screen and linear vibrating screen. horizontal screen has the features of good screen permeability, large processing capacity and small installation height

The installation angle of common vibrating screen is 15°-30°, while the installation of horizontal screen is parallel to the ground, or slightly inclined 0-5°. Horizontal screen is an ideal equipment for all kinds of mines, quarries and mobile screening stations

Working Principle: Horizontal screen is designed with oval stroke. The advantage of this design is that it can change the oval big diameter length and angle of throwing material stroke to meet the best needs of vibrating screen. The oval stroke is easy to adjust by center gear, counterweight wheel and motor speed.

Different types of vibrating screens can be used for the same material to get different screening effects. The reasonable selection of vibrating screen is an effective way to improve vibration efficiency and maximize economic benefits. Generally, you need to consider the following 5 tips:

When choosing vibratory screen, the material characteristics should be taken into account, including the content of material particles under the screen, the content of difficult screen particles, material moisture, the shape and specific gravity of the material, and the content of clay.

Tips: Heavy vibrating screen is used for materials above 200mm; circular vibrating screen is used for materials above 10mm; linear vibrating screen and high frequency vibrating screen are used for desliming, dewatering and grading

construction, working and maintenance ofelectric

When selecting the vibratory screen, the screen areas, layer numbers, shape, size and area ratio of the screen holes, as well as the motion mode, vibration frequency and amplitude of the vibrating screen should also be considered

Tips: In order to keep the screens under good working conditions, the ratio of screen length to width should be in the range of 2-3; when there is much viscous mud and high moisture in the material, double deck screens should be avoided as far as possible

Vibratory screens need to be selected according to different screening purposes. If it is necessary to pre screen materials, circular vibrating screens are generally used; for the classification and screening of crushed materials, large vibrating screens and probability screens are selected; for the deionization and dehydration of materials, linear vibrating screens are better; if it is necessary to desliminate and clean up materials, probability screens are used.
