Jaw Crusher

Jaw crusher, commonly known as tiger mouth, is an efficient and energy-saving crushing equipment. Jaw crusher simulates the movement of the two jaws of animals to complete the material crushing operation. Specifically, the motor drives the eccentric shaft to rotate through the pulley, so that the movable jaw periodically approaches and leaves the fixed jaw, thereby producing multiple crushing effects such as squeezing, rubbing, and grinding on the material, so that the material changes from large to small, gradually falls, and is discharged from the discharge port.

1. Structure and composition of jaw crusher

The main structure of jaw crusher includes frame, eccentric shaft, large pulley, flywheel, movable jaw, side guard plate, toggle plate, toggle plate back seat, gap adjustment screw, reset spring, fixed jaw plate and movable jaw plate. Among them, the toggle plate also plays a role of insurance.

2. Performance characteristics of jaw crusher

a. Deep crushing chamber and no dead zone: improve feeding capacity and output.

b. Large crushing ratio: uniform product particle size.

c. Gasket type discharge port adjustment device: reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment.

d. Simple structure: reliable operation and low operating costs.

e. Energy saving of equipment: 15%~30% for single machine and more than double for system.

f. Large adjustment range of discharge port: can meet the requirements of different users.

g. Low noise and less dust: beneficial to environmental protection and operator health.

3. Classification and specifications of jaw crushers

Jaw crushers are generally divided into two types: compound pendulum and simple pendulum, mainly used for coarse and medium crushing. In recent years, compound pendulum jaw crushers for fine crushing and powerful jaw crushers for crushing high-strength, high-hardness micro-carbon chromium iron have appeared.

The specifications of jaw crushers are usually classified according to the width of the feed port, which are divided into three types: large, medium and small. The feed port width is greater than 600mm for large machines, the feed port width is 300~600mm for medium machines, and the feed port width is less than 300mm for small machines. In addition, there are many specific models and specifications.Each model has its specific feed port size, maximum feed particle size, discharge port adjustment range, processing capacity and other technical parameters.

4. Application fields of jaw crusher

Jaw crusher is widely used in environmental protection, mining, metallurgy, building materials, highways, railways, water conservancy and chemical industries, etc., for crushing various ores and bulk materials with compressive strength within a certain range.

PS: Jaw crusher occupies an important position in the crushing equipment market with its unique structure, excellent performance and wide application fields.
