Jaw crusher

Jaw Crusher Overview

Jaw Crusher is a primary crushing machine used for coarse crushing plant in stone quarrying and mine ore mining process. The crushing ratio can reach 4-6 and the fineness of even final product is 10mm - 40 mm. The capacity of small jaw crusher is from 1 t/h- 4 t/h, while the large scale jaw crusher is 200 TPH - 800 tons per hour.

Application of Jaw Crusher

jaw crusher series PF has properties of large crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, and low cost. So this kind of jaw crusher can be widely used in mining, metallurgy, iron ore, building material, highway, railway, water project, chemical industry, etc, for crushing various material with compression strength less than 320MPa.

The common minerals can be crushed by jaw crusher are:

Natural rocks	Ore Minerals
Granite	Limestone	Basalt	Quartz	river stone
Gold ore	Iron ore	Copper	Manganese	Bauxite

how a jaw crusher works and component of jaw crusher

Jaw crushers are equipped with one fixed and one moveable crushing jaw (moving jaw), both of which support crushing plates (wearing parts) in several versions. They form a wedge-shaped crushing zone. The walls of the crushing zone are made of replaceable wearing sheets. Crushing is done between the two crushing jaws. The moving jaw of the single toggle jaw crusher moves elliptically. A pendulum motion is being carried out by the double toggle jaw crusher.blake jaw crusher is is widely used in mining and quarry.

The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring pulling rods keep the whole system in a condition of nonpositive connection. Centrifugal masses on the eccentric shaft serve as compensation for heavy loads. A flywheel is provided in the form of a pulley. Due to the favorable angle of dip between the crushing jaws, the feeding material can be reduced directly after entering the machine. The final grain size distribution is influenced by both,jaw crusher is the adjustable crusher setting and the suitability of the tooth form selected for the crushing plates.

An adjustable wedge system makes infinite adjustments of the crusher setting possible. The systems, spindles exert a direct influence on the thrust-bearing trestle. All parts of the adjusting system are accessible, maintenance-free and easy to replace.

All of the toggle plates are provided with replaceable tempered pressure bars on both sides, which work according to the move on rolling contact principle. They are maintenance-free. A lubrication system ensures sufficient grease supply to all other bearing points.

Process of Jaw Crushing Plant

The Big materials are fed to the primary jaw crusher evenly and gradually by vibrating feeder through a hopper for the primary crushing. After first crushing, the material will transferred to impact crusher or cone crusher by belt conveyor for secondary crushing; the crushed materials will then transferred to vibrating screen for separating.

After being separated, the parts that can meet standard will be taken away as final products, while the other parts will be returned to impact crusher, thus forming a closed circuit. Size of final products can be combined and graded according to customer specific requirement. We can also equip dust catcher system to protect environment.
