Small Size Stone Sand Screening Machine Rotary Drum Trommel Screen
Introduction
Small size stone sand screening machine rotary Ddrum 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.
Brief description
Rotary trommel screen provides a simple, efficient and economical solution to upgrade a
wide range of material and optimizes the subsequent process steps
of recovery.This method of screening helps to reduce operating and
investment cost to increase product quality, while allowing rapid
and large volume processing.
Small size stone sand screening machine rotary Ddrum trommel screen widely used for alluvial gold sieving and graded washing.It
provides a simple, efficient and economical solution to upgrade a
wide range of material and optimize the subsequent process steps of
recovery. This method of screening helps to reduce operating and
investment cost and to increase product quality, while allowing
rapid and large volume processing.
It has the following advantages
1. The installation of a small angle of inclination, is not easy to
plug.
2. To occupy a small space.
3. Low noise, less pollution and dust.
4. A smooth operation.
5. Efficient screening.
Working principle
1. Downstream process equipment can be in various forms such as
centrifugal Concentrator, spirals, jigs etc.
2. Trommel screens are constructed of high quality material,
designed for high performance, high production rates, lower
operating costs and lower maintenance.
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.

Application
Small size stone sand screening machine rotary Ddrum trommel screen are always used for refractory materials, inferior coal, coal
slime, bottom ash,sand classification, sandstone block
classification.
Trommel screen machinery is widely used in many industries, such as mining, building
materials, metallurgy, casting, abrasive material, chemical, light
industry, medicine and food industries.
