High efficient Jaw crushers for highway construction 

I. Jaw crushers for highway construction Usage and Application

Jaw crushers for highway construction is very common in the field of Mining and quarry. This kind of Jaw crushers for highway construction is widely used in mining, building materials, chemical industry, metallurgy and so on. Jaw crushers for highway construction is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa.

II. Jaw crushers for highway construction Structure and Working Principle 

Structure

The Jaw crushers for highway construction is mainly composed of frame,  fixed jaw plate, movable jaw plate,  left and right guard plates,  movable jaw, eccentric shaft, toggle plate,  adjustable base,  adjustable screw stem,  adjustable wedge block,  fitting of tension spring and so on.

Working Principle 

When the Jaw crushers for highway construction is working, the belt and belt pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It becomes bigger when the movable jaw runs up. The movable jaw plate leaves the fixed jaw plate under the action of tension rod and spring , then the end products come out from the crushing cavity.

III. Jaw crushers for highway construction Advantage and  Main Specification

 Advantage
1. High degree of automatic operation; the entire production line requires almost no manual operation except for machine starting and stopping, routine maintenance.
2. High productivity, low investment, and good appreciation.
3. Regular end product granularity, good grain shape, and low powder.
4. Adopting high advanced central control system to ensure security and reliable operation of the entire production line.

Main specification

The machine is fixed tightly when it is sent to the port by professionale truck. Before shipped, it is covered by waterproof material to avoid moisture and rough handling.

Jaw crusher plant for highway construction with S1, 3/8, 3/4, G1 standard

A gentleman from Philippines consults for a jaw crusher plant for highway construction, the main specifications as follows:

Raw material: stone

Input size: 500 mm

Output size: S1, 3/8, 3/4, G1

Capacity: 100 tons per hour

As this project, a primary jaw crusher and fine cone crusher is needed. As the input size is 500 mm, PE 500 x 700 jaw crusher is not suitable. Because the figures represent the feeding size of the machine is 500 mm x 750 mm, and the best raw material size is 80% of the smaller figure - 500 mm, which is 425 mm. So PE 600 x 900 jaw crusher is the best.

And to match the jaw crusher, 4 1/4 Spring Cone Crusheris needed. This type spring cone crusher is 4.25 feet, it has large capacity and fine output size which can reach S1, 3/8, 3/4, G1 standard. The two combined machine forms a stone crusher plant.
