What is a jaw crusher?

Jaw crusher is a commonly used mining machinery and equipment, which crushes larger stones or ores through the mutual extrusion of fixed jaws and movable jaws. Its main function is to reduce the size of mined ore for processing or transportation. Trituradores da mandíbula (for sale) are used to great effect in mines and quarries as well as in recycling processes where the reduction of bulky materials is required. The crushing equipment is widely used in mining, metalurgia, materiais de construção, construction and other industries.

Basic components of jaw crusher

1. Fixed jaw and movable jaw
2. Jaw liner

How does a jaw crusher work?

After having a basic understanding of the jaw crusher machine, let’s see how the jaw crusher works.

Feeding stage

The ore or rock to be crushed enters the crushing chamber (the volume or cavity between the two jaws) through the vibrating grid feeder. The power provided by the motor rotates the eccentric shaft. As the eccentric shaft rotates, the movable jaw reciprocates.

Crushing stage

At this time, the ore or rock enters the crushing chamber. The movable jaw begins to exert pressure on the rock in the crushing chamber. The ore is squeezed into smaller pieces and gradually flows down to the lower discharge port.

Discharging stage

After the ore is crushed to a set size, it is discharged from the crushing chamber through the lower discharge port. The size of the final product can be pre-set.

How to adjust the discharge size?

Use wedges or hydraulic systems to adjust the gap between the two jaws.

SBM jaw crushers include safety features such as toggle plates. It protects the crusher from overload or uncrushable materials. Jaw crushers are heavy machines, so regular maintenance ensures that the jaw crusher operates efficiently. Maintenance operations include lubricating bearings, checking jaw wear, and tightening or replacing any loose or worn parts.
