2012-7-4  the capacity. Impact crushers: they involve the use of impact rather than pressure to crush materials. The material is contained within a cage, with openings on the bottom, end or side of the desired size to allow pulverized material to escape. This type of crusher is usually used with soft material such as coal, seeds or soft metallic ores.

The Effects of Blasting on Crushing and Grinding

2013-4-21  is .33 kg/ton, or .31 kwh/ton. Thus, the efficiency compared to Bond is 77 percent. This is likely due to the variable nature of rock and the transmission of the energy, and the possibility that Wi is greater than 14.87 in the unblasted state. The cost for the explosives however is that associated with the powder factor of .31 kwh/ton.
