Roller Screens

Screening machines, is the use of granular materials and the relative movement of the screen surface, so that part of the particles pass through the sieve, sand, gravel, crushed stone and other materials according to particle size is divided into different levels of vibration screening machinery and equipment. Particle level depends on the screen surface screening, screen surface points grate plate mesh sieve and three. Grate material suitable for screening large particles, grate gap of sieve was 1.1 to 1.2 times the diameter, generally not less than 50 mm. Made from sheet steel sieve plate punching holes were round, square or rectangular aperture is generally 10 to 80 mm, long life, easy to plug, is suitable for screening medium particles. Compiled by a wire mesh screen or welded into the hole was a square, rectangular or elongated, generally common aperture 6 to 85 mm long strip of mesh material suitable for wet sieving, the advantage is that the effective sieve area than Great. Burning power plant coal-fired boiler is a certain percentage of the particle size of coal gangue, coal in the coal mine to its uniform particle size, particle size of coal in most materials are qualified particle size need not be repeated broken. This part of the material is generally about 35 to 75% of the entire material. Now many domestic screening equipment. Commonly used screening equipment can be divided into two categories, one is the vibration conveyor type, one is forced to transfer type, each with advantages and disadvantages between the two. As noted in the case of the parameters it is best to root material to the selection.
