When the screen mesh damage probability is too high, please pay attention to the following points

　　1, the compression of the grid is very important! Because the screening principle of the linear sieve is the linear motion of the material subjected to the force of the parabola, when the grid pressure is not tight, the grid is also subjected to the upper and lower force movement, and the screen is simultaneously with the grid. Doing up and down movement, so the screen is easily broken from the edge of the pressure net;

　　2, the flatness of the grid: Because the screening principle of the linear sieve is the linear motion of the material subjected to the force of the parabola, when the flatness of the grid is not good, the material is difficult to make a uniform linear motion on the sieve surface, the material It is easy to move the ditch like water. At this time, it not only affects the output and quality of the screening, but also increases the part of the screen due to the movement of the material. At this time, the grid is also subjected to the upper and lower force movement. The grid is moving up and down, so the screen is easily broken from the edge of the pressure grid;
