Evaluation of size reduction process for rock aggregates ...

2020-6-4 · The crushability, grindability, and cutability of rocks are associated with many factors. During the size reduction processes in a jaw crusher and rod mill, crushing and grinding energy consumption increase when finer size fractions of the product are desired (Zeng and Forssberg 1992).Heikkilä (Heikkila 1991) reported that the lithological features affect the attrition typology of rocks in ...

Jaw Crusher Working Principle

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.

2014-9-15 · It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft.
