Evaluation of size reduction process for rock
2020-6-4 For this purpose, several mineralogical, physico-mechanical, and aggregate properties of 17 rock types were determined. The crushability tests were performed using rock aggregates with a particle size range of 11.2–16 mm. Before and after crushability tests, initial and final PSD of rock aggregates were determined by sieve analyses.

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech
2009-7-30 The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers

Modelling of crushing operations in the aggregates industry
2015-3-2 using the Kuz-Ram distribution a different feed size distribution was used to represent each ore type from the same blasting conditions. It was shown that there is a relationship between the value of the constant representing the ore type in the Kuznetsov equation and the value of d50 in the product size distribution of the gyratory crusher. This shows that the blasting phase has a measurable effect on the
