DOUBLE TOGGLE JAW CRUSHERS
DOUBLE TOGGLE JAW CRUSHERS
Moderate Machines manufactures Double Toggle Jaw Crushers. The working principle is based on "crushing without rubbing". The machine consists of two jaws - one fixed and the other moving. The pitman moving on an eccentric shaft on bearings, and swing lever (moving jaw) swings on centre pin. The rock is held between the two jaws and crushed by mechanical pressure. The jaw stock is also completely welded and has renewable bushes. The pitman, made of high quality steel plates and carefully stress relieved after welding, is fitted with two renewable steel alloy or manganese steel toggle grooves. The eccentric shaft is machined out of alloy steel fitted with anti-friction bearings. Anti-friction bearings are heavy-duty double row self-aligned roller bearings mounted in the frame and pitman is properly protected against the ingress of dust and any foreign matter. The real faces of the crushing jaws are levelled by surface grinding in order to ensure that they fit snugly on the crusher frame and jaw stock. The crushing jaws are reversible to ensure uniform wear and tear of the grooves.
