Screen installation of linear vibrating screen
Screen cutting: the width is the same as the width of the grid, and the length is 50~70MM longer than the length of the grid;
The selection of the screen is very important, because the installation of the linear screen is relatively cumbersome, so it is necessary to select a screen with a relatively large diameter;
The tension of the screen is the main factor affecting the screening, so the screen must be tightened.
Screening net trawling selection: When the screening material is relatively heavy or the mesh number is high, the appropriate mesh trawling net should be installed under the screening net according to the mesh number of the screen. Its purpose is to support the screening network and reduce the pressure on the screening network.
Selection of clearing nets: Add ballistics according to the difficulty and mesh of the screening of the materials, and avoid blind loading of the marbles;
After the grid is assembled into the screen box as required, it is forbidden to place the grown screen at the upper end of the discharge port;
The mesh of each layer must have a sponge with strong elasticity as the sealing material of each layer, especially when the material has good fluidity or superfine;
Flatness and tightness of the pressure plate: The platen should be pressed evenly and evenly to ensure the flatness and fixation of the grid; the flatness of the grid directly affects the screening efficiency of the screen, and the compression of the screen directly affects The service life of the screen and the mixing of the products.
Test the assembly state of the screen: open the top cover of the sieve machine, and add a little material to test the fabric of the material. If the material is conveyed evenly, the flatness of the screen is intact; if the material is biased or ditched, It shows that the flatness of the sieve machine is not good, and the flatness of the sieve machine is adjusted appropriately; the sieved materials are tested. If there are obvious large-grain materials in the material, the sealing and compression of the screen are not good, and the adjustment is made. Compression and sealing;
