The efficiency of the screen is given by: 100(a − b) Efficiency = *100 (2) a(100 − b) Where: a % undersize in the feed. b % undersize in the oversize. 'a' was determined to be % *100. Upon sieving the oversize using the 8mm square panel, it was found that of fines had reported to the oversize. By using this mass, 'b' is determined ...

3. The product size of each case was determined, and then the crushed product is fed into a stack of sieve vertically arranged in such a way that, the sieve having larger openings are at top, and the finer openings are at the bottom. 4. The mass retained on each screen get calculated, and product size is measured graphically. TABULATION: GRAPH:
Design of a crushing system that improves the crushing ...
The products are then sent to a twin deck screen which is 25mm top screen and15mm bottom screen. Screen oversize are then sent to a 36 inch cone crusher running on a closed operation. The products are then sent to a 280 tonne bin. Research on the current crushing system led to the arrival of a decision to design a better crushing system. Some of the reasons are stated below: 1. The current ...
Screen efficiency calculation
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. Qms(o) = .
