JAW CRUSHER is a basic sample preparation unit and is essential to address all primary size reduction requirements. Desired crushing takes place when feed particles experience stress and the compressive pressure exerted by the jaw blade toggling action exceeds its fracture stress. By this action the feed particles are crushed to smaller sizes.

The crushing ratio indicates the size reduction capability of the jaw crusher. A higher ratio means the machine can reduce material to a smaller size. Typical crushing ratios for jaw crusher range from 3:1 to 6:1. 4. Motor Power. The power of the motor drives the jaw crusher and is usually specified in kilowatts (kW) or horsepower (HP).
