component which serves as an overload protection in jaw crushers. This toggle plate (Figure 2) is designed to fail when foreign objects become wedged between the crusher jaws, thereby preventing damage to the machine. The test pieces were placed under a cyclic loading in the hydraulic test rig until they failed as a result of fatigue. The cyclic

The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio.

The capacities are based on the crusher receiving full, continuous feed of clean, dry, friable stone weighing 100 lb/cu ft. These capacity tables show several significant differences between the two common types of primary crushers. A jaw crusher has a wider range of settings—generally, a maximum of two to three times the smallest setting.

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds

Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.

Cone crushers take care of secondary and tertiary crushing applications. Fine and medium-sized aggregates (used in asphalt and concrete, for example) are created by an eccentrically rotating shaft that grinds the rocks between a robust metal cone and a fixed wall. The Blackhawk 100 Cone Crusher is an example of a powerful cone crushing machine.
