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.
