The results suggest that for all four ores, the high voltage pulses products generated at an energy range 1–3 kWh/t have higher A * b values, with 9–52% increase in A * b values comparing to the conventional crusher product generated at similar specific energy. The data confirm the pre-weakening effect induced by high voltage pulses.

A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by:

The rod mill test gave RWilab of 14.5 kWh t −1 and a ball mill work index BWilab of 13.8 kWh t −1. Accepting that the rod mill work index applies to size reduction of the circuit feed down to the rod mill test product P80 of 1050 µm and that the ball mill work index applies from this size to the circuit product size, calculate the standard ...
