Rock Fragmentation Dan Crushing Equipment
Fragmentation is the basic concern in rock blasting and serves as the main measure of blasting effectiveness. A good estimation of fragment size distribution before blasting is very useful and helpful for selecting the proper equipment for loading, transporting, and crushing rocks.
Crushing and fragmentation of brittle spheres under double ...
Jun 25, 2004 · Brittle spheres are crushed and fragmented between two rigid platens dynamically. More than 140 plaster spheres with two different strengths (37 and 59 MPa) and three different sizes (50, 60 and 75 mm) were tested. The impact energies varied from 10 J to over 300 J with impact velocities ranging from 1 to 9 m/s.

Rock Fragmentation Prediction using Kuz-Ram Model
equipment, and importantly, the primary crushing units. Fragmentation is one of the most important concepts of Explosives Engineering. Blasting is the first step of the size reduction in mining and it is followed by crushing and grinding unit operations. The efficiency of these unit operations is directly related to the size distribution of muck pile.

The Effects of Blasting on Crushing and Grinding ...
Overly coarse fragmentation will reduce primary crusher throughput. Coarse material will lead to more downtime for clearing crusher bridging and plugging. Poor fragmentation will increase the load to secondary and tertiary crushing stages, if used, because there will be less undersize that can be split off to bypass these stages.

The Energy Cost Per Ton of Blasting is Far Less Than the Cost Per Ton of Crushing Why We Focus on Fragmentation Because it is the first time the mine has a chance to make big rocks into little rocks. It can be cheaper than crushing and grinding and more efficient if you find the perfect spot between over blasting and under blasting.
