The role of drum screen stone equipment in work

The drum screen is mainly composed of a motor, a reducer, a drum device, a frame, a sealing cover, a material inlet and outlet, etc. The motor and the drum device are connected through a coupling to drive the drum device to rotate around its axis. When the material enters the drum device Afterwards, it will be driven to turn and roll continuously. The relative movement between the material and the screen surface makes the particles smaller than the mesh penetrate

Here mainly talk about the replacement of the screen and some matters to be paid attention to.

1. After the drum screen frame is assembled to the screen box according to the requirements, remember to extend the extra 50-70mm screen into the corresponding discharge port to avoid the phenomenon of mixing materials here;

2. When cutting, the width of the drum screen mesh should be consistent with the grid frame, and the screen length must be 50~70mm longer than the drum screen frame;

3. When the screen is installed, it must be tightened, because the tension of the screen is an important factor affecting the screening efficiency of the trommel screen;

4. When installing the net cleaning bouncing ball, you must pay attention to the screening difficulty and mesh number of the material, and you cannot install it blindly;

5. If the specific gravity of the material is large or the screen mesh required to be installed on the trommel screen is high, a supporting screen with a suitable mesh number should be added under the screen. The purpose is to play a supporting role and reduce the pressure of the material on the screen. , prolong its service life;
