Jaw crusher, featured in the simple structure, easy manufacturing, reliable work and easy maintenance, is widely used for industries like metallurgy, mining, building material, chemical engineering, coal, abrasives and ceramics, etc. Working area of jaw crusher is made up of movable jaws and fixed jaws.

Since jaws have to bear the strong crushing force and abrasion force, they are easy to be damaged. To protect the jaw plates, we usually install the wear-resistant linear boards on jaw surface. These boards are called crushing boards. Crushing board is usually in tooth shape. The tooth angle is dependent on the property and size of raw materials.

In general, the tooth angle changes from 90℃ to 120℃. Larger the size of raw materials, greater the toothed angle. As to the tooth distance, it is dependent on the size of finished products. During the working process ofjaw crusher, wearing speeds of crushing boards are different. Wearing speed of lower part is rapider than that of upper part.

When jaw crusher works, crushing boards directly contact with raw materials and bear the strong crushing force. Service life of crushing boards is directly related with the working efficiency and production cost of jaw crusher machine. Therefore, it is quite important to prolong the service life of crushing boards.

To prolong the service life of crushing boards, we can consider from the aspects like design, material selection and assembly, etc. See price list from website!
