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.
