Trommel screen

The trommel screen, also called mining rotary screen, is suitable for screening all kinds of damp, clay, and easily blocked materials, such as alluvial ore, coal, coke, white ash, sticky stone, etc. The trommel screen is a new generation of self-cleaning and screening equipment after the electric vibrating screen, it is distinguished with the ordinary mesh rotary screen, widely used for sieving all kinds of solid materials with particle size less than 300mm.
Comprehensive utilization power stations, which mainly burn inferior coal, are springing up rapidly in China. Coal-based fuels, mainly coal ores and coal slime, are usually sticky, wet, dirty and miscellaneous. There are common problems in the coal transport system, such as screen machine blocking, low screen efficiency, crusher wear badly, high energy consumption, etc. Luckily, The drum trommel screen can solve these problems effectively.

Capacity: 1-250 TPH as per requested

Procesible Material: All kinds of sticky clay material, include: coal & coke/ sand & gravel/ alluvial gold / river sand/ beach sand/ kaolin clay/ and various minerals ore like tin, tungsten, chrome, coltan, zircon, diamond, iron, manganese.

Application
Aggregate processing plant, sand & gravel classification, soil and sand separation. eg: river sand, pebble.
Coal & coke industry lump coal separation, coal washing.
Mineral processing plant, ore material screening and washing. eg: gold mining, alluvial gold separation.

Types of trommel screen: heavy duty without shaft rotary screen, standard type rotary screen (single layer, multi-layers, single layer with multi sectors), mobile drum screening, mobile diesel generator gold separator.
It can be customized according to the material size, type and output and so on requirements.

Main parts: motor, reducer, roller device, rack, sealing cover, inlet and outlet.

Working principle of trommel screen
The motor drives the drum axis to rotate, the reducer adjusts it rotates at a certain speed. Under the centrifugal force, the material moves and gradually be screened out through sieve holes.
Due to the different sizes of the screen, the materials are separated and sieved gradually, and the qualified materials fall into their respective funnels, and then are transported to the finished product station by conveyor. Discharge the unqualified material and clean the drum body avoid clogging.

Advantages:

It is a highly economically viable option adequately suitable for small to large volume processing of materials.
The trommel screen has high efficiency and a big capacity for different volumes of materials.
The screen features various filters for different heavy duty drums that ensure complete separation of fine materials.
The drum screen is uniquely designed to facilitate higher capacities, provide longer screen life and avoid material clogging.
