Primary jaw crusher is a kind of crude crushing equipment which is mainly used for primary and crude crushing of all kinds of hard rocks and block materials. Large and medium-sized jaw crushers are the leading products of our company and have been in the lead now both at home and overseas. Jaw crusher is widely applied for primary crushing of hard materials. And it is widely used in the following industries: minerals, quarry, building materials, road, rail way, water conservancy and hydropower and so on.

Jaw Crusher

According to the wear rules of jaw plate of stone jaw crusher, usually the upper place of set tooth plate has the big wear, for this, we will change the set jaw plate to the ‘linear--modified gaussian curve type.’ The design has the best results. The fact shows it really improve the wear of jaw plate of jaw crusher, and we adopt the alloy materials so that jaw crusher has the more longer life time.

To promise the number of squeeze of materials in the cavity of primary jaw crusher, we improve the break ratio. The technology add the height of the crushing cavity and form the high-deep type crushing cavity. And to improve the capacity, we derived a new formula of eccentric shaft speed, the patent product of eccentric shaft speed can reach 330-350 RPM. This increases the oscillation frequency of hubei,and strengthened the crushing effect, and improve the crusher machine production.

The motor drives the belt wheel, and makes movable jaw up and down by eccentric shaft. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be crushed to reach the crushing target. When the movable jaw is down, the angle between the fixed jaw and movable jaw becomes smaller. The movable jaw plate leaves the fixed jaw plate under the function of drawbar and spring, and then the crushed materials are discharged from the lower outlet of the crushing cavity.
