Few problems • A certain crusher accepts a feed of rock having diameter of 0.75 in and discharge a product of diameter 0.2 in. the power required to crush 12 tons per hr is 9.3 hp. What should be the power required if the capacity is reduced to 10 ton per hr and as a consequence of which the diameter of product become 0.15 in?
1000 cm3 2.5 kg 300 mm Because of the benefits from compaction, contractors have built larger and heavier machines to increase the amount of compaction of the soil. It was found that the Standard Compaction test could not reproduce the densities measured in the field and this led to the development of the Modified Compaction test.

A jaw crusher size is obtained by looking at its feed opening (gape) and length. As an example, a monster 7959 of 79″ x 59″ (2m x 1.5m) will have its fixed jaws 79″ apart where the feed enters on a 59″ wide set of liner plates. The factors list below will enhance crusher capacity and performance: 1. Proper selection of the jaws. 2.

Crusher Performance Map • The general idea: – Select a crusher where you think optimization will be beneficial – Make a plan for what you would like to test • CSS, Speed, Curtain Position… – Run a sampling campaign • Particle size distribution, shape, capacity – Do the analysis • Convert test results into values of performance
Therefore, both productivity optimization and product quality optimization are taken into account, the optimal performance parameters of the crusher C900 were obtained, the mantle bottom angle is in the range of 50° to 60°, the length of the parallel zone is in the range of 140 mm–190 mm, and the eccentric angle is in the range of 1.4°–2°.
