Jaw crusher introduction. 05-20-21; 607 Views; icon 0; Jaw crusher, also known as tiger mouth. The crushing chamber is composed of two jaw plates, a movable jaw and a static jaw, which simulates the movement of the animal's jaws to complete the material crushing operation. It is widely used in the crushing of various ores and bulk …

The capacity of a jaw crusher is given by the amount of crushed material passing the discharge opening per unit time. This is dependent on the area of the discharge opening, the properties of the rock, moisture, crusher throw, speed, nip angle, method of feeding and the amount of size reduction.

It is crushed by the combined action of crushing, splitting and bending. When the movable jaw leaves the fixed jaw, the broken ore is discharged by gravity through …

When machinery was introduced into the road-stone quarries, in about 1895, for the preparation of macadam, the jaw breaker was used for coarse crushing and heavy slowly-moving rolls were adopted in some of the quarries for finishing the stone. A few of these machines are in service to-day.

The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.P80 = 25400 …

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.
