The work input shown for blasting is calculated by the Bond equation. The actual energy input 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.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank),.
Product Introduction: Jaw crusher. kmc jaw crusher with high production capacity, large reduction ratio and high crushing efficiency. Production capacity: 5～800t/h. Product Improvement: kmc improves the traditional specification of crushing chamber by adopting high speed swing jaw and cambered jaw plate.
