Introduction

Trommel screen is consist of five parts as drum, frame, hopper, reducer and motor. After the broken stone into the drum, on the one hand, materials being screened along with the rotation of drum, on the other hand, the bigger materials flow forward along the direction of slope and be separated by the screen with different number of meshes. The different materials fall into different hopper and then be sent to different finished product stacks by manpower or belt conveyor.

Application

According to different sizing specification, the numbers of hierarchical level could be from one to four. materials whose size is larger than the screen mesh of the last part will be discharged from the outlet.

During the process of operation, its movement is slowly and steady and installation is simple, sometime no need any special foundation and could be placed on smooth ground or floor.

It is the most commonly used classification device for refractory material, coal, river sand and mixture of sand and stone.
