Mobile Type Coal Mining Carbon Steel Rotary Trommel Screen

Introduction

Mobile Type Coal Mining Carbon Steel Rotary Trommel Screen’s main structure is cylindrical drum, which is inclined and installed on the frame.The geared motor is connected to the drum device through a coupling, the driving drum will rotate around the axis direction.When the materials enters the drum device, due to the tilt and rotation of the drum device, the materials on the screen surface is overturned and rolled so that the fine material is discharged through the discharge port at the bottom of the back end of the drum of trommel screen, and the coarse material is discharged through the discharge port at the tail of the drum discharge. As the material in the drum devise flip, rolling, so the materials stuck in the sieve can be ejected to prevent the sieve blocking.

Mobile Type Coal Mining Carbon Steel Rotary Trommel Screen consists of motor, reducer, screen frame, inlet, outlet, support base, and so on.

Working principle

1. Trommel screens are constructed of high quality material, designed for high performance, high production rates, lower operating costs and lower maintenance.
2. Downstream process equipment can be in various forms such as centrifugal Concentrator, spirals, jigs etc.
3. After the materials are fed into the drum, the materials are classified, while the bigger materials flow forward along the inclination of drum and was classified through different mesh screens gradually. Classified small materials fell into respective bunker, and are delivered into finished product stack through manpower or belt conveyor.

Advantages

1. Wide adaptability of materials

The trommel screen is widely used in screening of various materials, regardless of fault coal, coal slime and soot and other materials, they are all screened smoothly.

2. High screening efficiency

It is equipped with comb-type screen cleaning mechanism, no matter how dirty and miscellaneous the materials that have entered into the screening drum during screening, thus increasing the screening efficiency.

3. Large screening volume, easy for large scale

Under the same size, the area of a circle is larger than that of any other shape, so the effective area of its screening is larger, materials can fully touch screen cloth, thus the screening capacity in unit time is larger. It is also easy for large scale due to simple structure and convenient arrangement.

4. Good working environment

The whole screening drum can be sealed with sealing isolation hood, thus reducing the noise of equipment, and thoroughly remove dust flying, lump splashing during screening circulation process, avoiding pollution to working environment.

5. Convenient maintenance

The upper sealing isolation hood can be taken apart, which does not affect the normal operation of machine, and allows very convenient maintenance

Application

Mobile Type Coal Mining Carbon Steel Rotary Trommel Screen are always used for refractory materials, inferior coal, coal slime, bottom ash,sand classification, sandstone block classification.
