Gyratory and Cone Crusher
Power Consumption of Gyratory and Cone Crushers. To compute the power consumption of gyratory crushers, knowledge of the ore work index and crusher capacity is necessary. In its simplest form, the power consumption is given by (5.5) P = W i Q F 80 − P 80 F 80 100 P 80 where P = power (kW) W i = work index (kWh/t) Q = capacity (t/h)

Optimal energy management for a jaw crushing process in deep mines
Compressive crushers such as jaw, gyratory and cone crushers are known to be inefficient machines with the no-load power ranging from 30 to 50% of their rated power [18], [19]. Hence, one way to improve the efficiency of these machines is through their operation efficiency by reducing their energy consumption and cost during their operation.

In 1950, the American Fred Chester Bond put forward the "crack theory," which believed that "the power consumption of the crushing process is proportional to the length of the cracks formed during the crushing process." The theory became the widely used "third theory" of crushing and is suitable for medium and fine crushing.
