1, the width and length of the linear vibrating sieve surface of certain materials, productivity depends on the width of the screen surface, screening efficiency depends primarily on the length of the screen surface. In the linear shaker productivity and material along the screen surface velocity is constant, the larger the width of the screen surface, material thickness will be thinner; greater the length, the longer the screening time, reducing material thickness and screening times are lengthened help to improve screening efficiency, long narrow face when the screen when the screen surface material layer thickness increases, the fines are difficult to access through the sieve screen surface and to reduce the amount of ore and screening efficiency; conversely, the screen surface wide and short, the screen surface material layer thickness reduced to fine easy through the sieve, but this time the screen surface residence time of the particles in short, to reduce the probability of the sieve through, so screening efficiency will be reduced, usually sieve the ratio of length to width of 2 to the surface 3.
2, linear vibrating sieve surface inclination, under normal circumstances, linear vibrating screen is tilted installed in order to discharge the sieve material. Inclination to the right size, angle is too small, the material in the screen surface movement is too slow, although the high screening efficiency, reduce productivity but gridiron; conversely, dip too large, material discharged too quickly, reduce the screening efficiency. So inclination screen surface should be appropriate.
Dahan mechanical linear vibearion screen with high precision, large capacity, simple structure, low energy consumption, low noise, screen long life, good sealing, no dust, easy maintenance, can be used for assembly line production advantages of automation, and has been widely applied in many industries.
