Drum screen, with large volume, is a cylinder. It mainly consists of the motor, reducer, drum device, screen, frame, sealing cover, inlet and outlet. The drum device must be equipped with a steel ring to prevent the deformation of the drum screen.

It is widely used in the screening of raw coal, crushed stone and other materials in alumina plants, power plants, coking plants, cement, mining, metallurgy, building materials, coal chemical industries, etc. It is key screening equipment in the coal chemical industry.

Linear screens mainly screen fine particles with light specific gravity and low-hardness, mainly dry materials. They are usually used in food, chemical, building materials, and pharmaceutical industries.

When the materials are fed into the drum screen, due to its tilt and rotation, qualified materials (undersize product) are discharged through the discharging port at the bottom of the rear end of the drum, while unqualified materials (oversize product) are discharged through the other discharge port.

The linear vibrating screen adopts a vibrating motor as the vibration source, so the material is thrown up on the screen. Then several specifications of undersize products and oversize products are produced through the multi-layer screen. Finally, they are discharged from their respective outlets.

Generally, the inclination of the drum screen is 5-30. It is generally close to 30 for light and fine materials. When the material is heavier, it can be less than 20, and in special cases, 5-10.

The inclination of the circular vibrating screen is suitable when it is 20, and the general range is between 16-20. If the inclination angle is less than 16, the material on the screen may not move smoothly or roll upward.

The vibrating screen is screening equipment with a vibrating motor as the vibration source, so its screening accuracy is high. The trommel screen is high-output screening equipment with the screening accuracy not as high as the vibrating screen.

As for the circular vibrating screen, the material moves in a parabolic circular trajectory on the screen surface, so the material is dispersed as much as possible to improve the material's bounce force.

The quarry vibrating screen is mainly used to screen gravel, and the quality of the screen mesh determines the material screening efficiency. Therefore, quarry investors or equipment purchasers will ask the manufacturer for information about vibrating screen media types when choosing a vibrating screen.

Rayco designs and manufactures a complete set of high quality and cost-effective rubber screens. They are used to treat the roughest and most abrasive products, such as gravel, coal, slag, etc. Rubber material is soft and powerful, can absorb shock and have long service life, which not only can reduce the downtime, but also makes installation easier and faster. If noise reduction is required, rubber screens are good choices.

Rayco rubber sieve can be divided into two kinds: tension and modular. The tension type can be installed as a circular vibrating screen and replace the original metal screen or polyurethane screen. The modular type can be installed in many ways, which can better save operating costs.

The polyurethane screen is made of polyurethane and embedded in a steel frame. It has a specially designed fastening hook to clamp the mesh to the separator. Polyurethane screen has excellent performance in mining crushing and aggregate screening industry. Different sizes and types of mesh hole ensure high screening efficiency and smooth surfaces. Polyurethane materials make mesh noise much lower than braided vibrating mesh or perforated mesh.

Our polyurethane screens can effectively screen materials for many industrial applications, such as dehydration, mining, sand, stone, gravel, etc. Polyurethane is ideal for high wear areas in both wet and dry processing applications.

THe high-strength woven wire screen is made of best steel wire like manganese steel wire, galvanized steel wire and stainless steel wire. The mesh hole can be square, rectangular, or longslotted. With a variety of woven types, it can be suitable for different screens and materials.

The perforated screen is made of a metal plate with high compressive strength after punching. Compared with woven vibrating screen, porous vibrating screen has a smooth surface, which can ensure higher screening and separation efficiency.

Overview of GS cylinder rotary screen (cylinder screen): The main structure of GS cylinder rotary screen is the screening cylinder, which is composed of several circular screens. The screen is inclined to the ground plane as a whole, and the outside is sealed by a sealed isolation cover to prevent environmental pollution. The screening cylinder rotates at a certain speed through the variable speed deceleration system, the materials are separated from top to bottom through the screening cylinder, the fine materials are discharged from the lower part of the front end of the screening cylinder, and the coarse materials are discharged from the lower end of the screening cylinder. The cylinder rotary screen can be equipped with a comb type cleaning mechanism. In the screening process, the relative movement of the comb type cleaning mechanism and the screening cylinder can achieve the effect of continuous cleaning of the screen body, so that the screening cylinder is always clean, non stick, non blocking and does not affect the screening effect in the whole working process. According to different classification requirements, GS cylinder rotary screen generally has 1-4 sections from fine to coarse, and materials are screened from the first section to the last section from fine to coarse, and materials larger than the last section are discharged from the outlet. GS cylinder rotary screen in the use process, the operation is slow and uniform, the impact vibration is very small, the work is stable, its installation is simple, sometimes even does not need special foundation. It can be directly placed on the flat ground or floor and under the silo. The machine is easy to close and collect dust, with small amount of maintenance, simple maintenance and long service life.

Wide adaptability of materials: rotary screen is widely used for screening of all kinds of materials. No matter it is inferior coal, slime, soot and other materials, they are screened smoothly. 2. Simple and diverse feeding modes: the feeding port of rotary screen developed by our company can be designed according to the actual situation on site. No matter it is belt, funnel or other feeding modes, it can be smoothly fed without taking special measures. 3. High screening efficiency: the equipment can be equipped with a comb type cleaning mechanism. In the screening process, no matter how dirty and miscellaneous the materials entering the screening cylinder can be screened, thus improving the screening efficiency of the equipment. 4. Large screen weight, easy to be large-scale Under the same size, the area of the circle is larger than that of other forms, so the effective area of screening is larger, so that the material can fully contact the screen, so the screening component is larger in unit time. Because of its simple structure, convenient layout, novel and mature technology, it is easy to be large-scale. 5. Low energy consumption The power of the rotary screen motor developed by our company is small, which is one-half to one-third of the other screen types. It can handle the same amount of materials and the operation time is only one-half of the other screen types, so the energy consumption is low. 6. Good working environment The whole screening cylinder can be sealed by a sealed isolation cover, which completely eliminates the dust flying, block splashing and other phenomena during the screening cycle, and avoids the pollution to the working environment. 7. Low equipment noise In the operation of the rotary screen, because of the small rotary speed and the sealed isolation cover, the noise can not be transmitted to the outside, so as to reduce the noise of the equipment. 8. Long service life and small maintenance The rotary screen is composed of several ring-shaped screens, whose total screening area is far larger than that of other screen types. In addition, the screening efficiency is high, and the running time of the equipment is short, so the service life is long, the number of vulnerable parts is small, and the maintenance amount is small. 9.

The trommel screen is a mechanical screening device used to separate materials like soil, mulch, and sand, ore, coal, gravel, mainly in the mineral and solid-waste processing industries, also called rotary screen or drum screen. We are manufacturer, all product sale on factory price. The products were exported to Thailand, Indonesia, South Africa, Australia, Europe, etc.

Its designed to minimize setup time and be easy and convenient to service. We have perfected the ability to size and customize drum screens with different materials to suit the application, such as the updated product compact sand washer.

The trommel separator is tilted on the rack. The motor is driven by the reducer to rotate the drum unit around its axis. After the material enters the drum device, due to the tilting and rotation of the drum device, the material on the screen surface is flipped and rolled so that the qualified material (the product under the screen) is discharged through the discharge port at the bottom of the drum screen, and the unqualified material(the product on the screen) is discharged through the discharge port at the tail.

For wet material, the machine drives the wet material to roll so that the materials are thoroughly mixed with the air. Making them drier, facilitating screening and reducing the blockage of the screen.

The McLanahan MD Vibratory Screen is a compact, high-capacity dry screening unit used in a variety of industries. It iscapable of screening more tons per hour per square feet of screen surface area and handling larger capacities than conventional screens, while occupying the same or less floor space. Additionally, the MD Vibratory Screen can make multiple product sizes simultaneously as progressively smaller material sizes are separated from deck to deck.

Animal feed (pellets and crumbles), dried sand, fertilizer, iron ore, wood pellets, quick and burnt lime, limestone, grain, gypsum, salt, and sugar are just a few of the materials and applications in which the MD Vibratory Screen is capable of screening efficiently and effectively.

Since its founding in 1835, McLanahan Corporation has established and maintained extreme standards regarding engineering, manufacturing, and customer service and support for all of its equipment product line offerings. These standards were continued in 1989 when McLanahan began engineering and manufacturing this style of screening equipment. We have extensive experience with screening a wide variety of materials and our laboratory is fully equipped to provide screen testing on your material.

McLanahan MD Vibratory Screens are available in widths ranging from 19 (48cm) to 78 (198cm) with one to five screen decks depending on the application. The MD Vibratory Screen is capable of handling feed sizes as large as approximately 3 (7cm) and can make size separations down to approximately 60 mesh.

Woven wire screen meshes of progressively smaller apertures are mounted in the compact vibrating frame at increasingly steeper angles. The apparent opening through which particles fall vertically is smaller than the actual opening because of the angle of the screen deck. In other words, the McLanahan MD Vibratory Screen makes a separation at a given size using a mesh aperture of greater size. This design concept reduces the risk of pegging and blinding, while achieving high capacities.

The rapid, vertical movement of the material gives the MD Vibratory Screen its large capacity in relation to the machine size. Because of its smaller size compared to conventional screens of the same capacity, excess energy is not wasted to move material forward. Instead, gravity does most of the work as material falls through the screen decks.

Depending on the model, the MD Vibratory Screen vibrates using one or two counter-rotating eccentric weighted vibratory motors. The horsepower of the largest motor on the largest MD Vibratory Screen model is only 8.3 hp. Mounted directly to the frame, the motor(s) sits and spins within itself; there is nothing to pull or push, no reducers, no pulleys and no belting. Motor bearings on the eccentric weighted drive are the only moving parts that require maintenance attention, normally in excess of 15,000 hours of operating time.

The MD Vibratory Screen is successfully used in a multitude of industries, including aluminum, ammonium, animal and pet food, ash, basalt, bauxite, cement, ceramics, clay, coal, coke, dolomite, feldspar, fertilizer, glass, grains, granite, gravel, gypsum, iron, lead, limestone, marble, pharmaceuticals, potash, quartz, rock, rubber, salt, sand and gravel, shale, silica, slag, sugar, wood pellets and more.

Yes, we can certainly help. We will need the product specifications in order to make that determination. It may also be possible that laboratory screening tests will need to be conducted in order for us to be able to verify that product specifications can be met.

The cost for laboratory screening tests vary depending on the extent of the material testing. Any costs associated will be discussed/communicated before we ask for a representative sample of material.

We only use woven wire screen media for our MD Vibratory Screens, typically mild carbon steel and/or stainless steel. Should a customer require anything other than these two types, that will have to be considered.

The reversing starter is an optional - but highly recommended -feature. Because of the excessive movement that is characteristic of the McLanahan MD Vibratory Screenduring shutdown, it is desirable to stop the machine as quickly as possible. The optional reversing starter panel accomplishes this by temporarily reversing the two leads to the motor (MD Screen Model SM) or motors (MD Screen ModelsDM or DMX). This action is termed plugging the motor. When the motor is plugged, the machine will come to an almost instantaneous stop (typically less than one second).

While the MD Vibratory Screen is commonly known as a dry screener, it can handle certain amounts of moisture if the materials moisture content falls within a general guideline that weve established based on our years of experience. This guideline is 1% moisture per 1.0mm screen opening. There are exceptions to this rule, but those exceptions are not very common. Usually, with damp material screen blinding occurs, which has a detrimental effect on the screening performance.

We have several features that assist with keeping the screens cleared of blinding or pegging material. We have a pneumatic screen tensioning system, ball decks, nylon chain, and offer cross-slotted and long-slotted screen openings.

Pneumatic tensioning is one of several methods used to protect against blinding of a screen mesh, and can be applied on all models of McLanahan MD Vibratory Screens. The pneumatic tensioning system governs the tension of a screen cloth such that it is periodically slackened and then re-tensioned. This slackening enables the screen cloth to rattle, removing sticking or pegged particles. Both the slackening period and the tensioning period can be adjusted at the control panel. Additionally, the pneumatic tensioning system is to be tied in with the machine's control logic so that the machine will shut down when the air pressure is insufficient to maintain proper tension on the screen cloth.

We will need the following information: type of material, bulk density of the material, required capacity, gradation analysis of the material to be screened, desired product size(s), material temperature at time of screening and material moisture content at time of screening. We have a questionnaire that can be completed and returned to us at your convenience.

A compact, high-capacity dry screening unit used in a variety of industries, the McLanahan MD Vibratory Screen is highly efficient and effective when it comes to sizing and separating materials. MD Vibratory Screens are available in a variety of sizes and models. They are capable of screening more tons per hour per square feet of screen surface area and handling larger capacities than conventional screens while occupying the same or less floor space.
