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.

Technical parameters

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.
