Dec 03, 2020· According to calculation, the max nip angle can reach to 32°, but in the actual production, the nip angle is generally between 18°-20°, smaller than 25°. If the nip angle is too large, the raw materials in crushing cavity will be squeezed out of the cavity, which may hurt operators or damage other auxiliary equipment.
Another equation proposed earlier (Allis-Chalmers, 1953; Flavel, 1977) gives the circulating load ratio Rg as a function of e and x, 1 1 x e Rg (2) where e is the % efficiency of the oversize removal, 100 x u is the percent oversize in the crusher discharge, and Rg is the circulating load ratio expressed as fraction of the new feed F. But, since 100 e r, Eq.
Screening can very easily be viewed as the most important operation in the processing plant. If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else. The performance of a screen is affected by four variables: eccentric throw, frequency (rpm), angle of adjustment and throw direction.
Sep 11, 2012· re vibrating screen efficiency calculation. Hello Raj, Screen efficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from the screen. The following information is required to calculate the two screen efficiencies;-Qms(f) = Mass flow rate of solid feed.
Sep 15, 2014· Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of several crushers, feeders and screens. This is not intended to be a typical situation, though it does involve common crusher and screen units often used in aggregate plants.
