Crusher size reduction ratio
Reduction ratio: way of measuring Crusher crushing effects, common reduction ratio of the concept. Crusher’s crushing ratio is ratio of raw material particle size and broken product accuracy. It expresses garbage reduced level after crushing.
Calculation method for crushing ratio
1, Calculate ratio having a maximum sized a product before crushing and broken product largest size: i=Dmax/dmax. Dmax: crushing of material before the largest size; dmax: the largest size after crushing the information.
2, Use crusher feeding mouth effective width and discharging mouth than width: i=0.85B/b. B: crusher feeding mouth width; b: crusher discharging mouth width. 0.85: make sure the effective width biting crusher materials coefficient. Discharging mouth width value: Thick crusher is taken maximum discharging mouth width; Medium crusher is taken the littlest in discharging mouth.
Calculated by this formula for crushing ratio is quite easy. Within the production of large volumes of materials might not always being screening analysis, using the way, just know crusher feeding mouth and discharging mouth width, after which can calculate the crusher reduction ratio.
3, Worth mentioning, some crushers’ row partical not by discharging mouth size to determine. Technology-not only this formula: i=Dcp/dcp. Dcp: the typical diameter before material crushed; dcp: the average diameter after material crushing. This process calculated crushing ratio, can create a real to reflect broken degree, thus theory research often put it to use.
