MODELLING FINES IN BLAST FRAGMENTATION AND ITS IMPACT ON CRUSHING AND GRINDING Sarma S Kanchibotla, Walter Valery and Steve Morrell Julius Kruttschnitt Mineral Research Centre The University of Queensland INTRODUCTION In the mining industry blasts are usually designed to fracture the in-situ rock mass and prepare it for excavation and subsequent transport.
4. Analytical modelling of rock fragmentation in impact crushers. An impact crusher fragments the rock by the dynamic strain energy introduced into the feed by the impactor. The process of dynamic fragmentation, by its nature, exploits the existence of flaws and micro-discontinuities. Hence, product fragments tend to be of good quality and shape.
Impact crusher is a crusher equipment which uses impact energy to crush brittle materials with medium hardness. When working, driven by the crusher motor, the rotor rotates at high speed, and the ore gains great kinetic energy from the impact process.

The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem.
The advantage in such a system is in dealing with a disruption in rock flow and hang-up before the crusher mouth with easier access to the problem area. Rock Crusher Types. Rock can be broken by compression, impact, and attrition in the various types of crushers developed for mining.
An impact crusher can be further classified as Horizontal impact crusher (HSI) and vertical shaft impact crusher (VSI) based on the type of arrangement of the impact rotor and shaft. Horizontal shaft impact crusher These break rock by impacting the rock with hammers/blow bars that are fixed upon the outer edge of a spinning rotor.
Rock fragmentation is a fundamental mining activity that affects the downstream processes; hence, there is a need of optimizing fragmentation. Optimizing rock fragmentation results in (i) maximizing crusher throughput; (ii) improving excavator productivity; (iii) minimizing equipment (i.e. excavator and crusher) maintenance and
Crusher - Wikipedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can ...
