Factors Affecting Efficiency of Circular Vibrating Screen

22/01/2013· There are a lot of factors affecting the working efficiency of the circular vibrating screen. However, there The first is the nature of the materials. The materials to be screened whose particle size is less than 3/4 of the sieve size are easily to pass through the sieve. When the circular vibrating screen is used to screen the fine materials, you can increase the auxiliary sieving method. You

The efficiency of the screen is given by: 100(a − b) Efficiency = *100 (2) a(100 − b) Where: a % under-size in the feed. b % under-size in the over-size. 2.555kg ’a’ was determined to be 21.35% i.e. *100. Upon sieving the oversize using the 11.965kg 8mm square panel, it was found that 0.285Kg of fines had reported to the oversize. By using 0.285kg this mass, ’b’ is determined

Mineral processing Wikipedia

Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding

11/09/2012· 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) = Mass flow rate of solid in the screen overflow. Qms(u) = Mass flow rate of solid in the screen underflow. Mu(f) = Mass
