Lower Jaw Crusher Drive System Failure Rate

Jaw crusher is commonly used in mineral processing production of primary crushing equipment, the equipment according to the activities of the different methods of swing jaw, divided into simple complex swing oscillating jaw crusher, jaw crusher and comprehensive oscillating jaw crusher. In jaw crusher in the process of crushing material will withstand larger torque and vibration, and thus it is easy to cause jaw crusher driving system fault.

In order to improve the jaw crusher work performance, reduce jaw crusher system failure frequency of rotation, we access to a lot of data and equipment was improved, according to years of experience to make the structure more optimization:

1. improve the design of the jaw crusher tooth Angle size

In the process of mineral processing production, ee according to the requirement of the concentrator row ore particle size to adjust the size of the row ore mouth. With the increase of tooth Angle, the broken ratio increases, the productivity will decline. Adjusting the size of the row ore mouth, can change the size of the tooth Angle. In adjusting the row ore mouth size should pay attention to crushing ratio and productivity of the relationship. At the request of the guarantee product granularity, as far as possible put the row ore mouth on the reasonable.

2. Improvement of the eccentric shaft rotation design of jaw crusher

Although the increase of eccentric shaft revolutions can improve the production capacity of mineral processing equipment, but the speed is too big, can make the discharge has been broken ore too late in the crushing cavity and produce jam phenomenon, what makes production capacity is reduced, power consumption is increased, so revolutions have adjusted to the right.

3. Improvement of design about jaw crusher movable jaw plate broken

We will be the shape of the jaw of jaw crusher activities make some change, make its upper ensure that eats Angle is changeless, and the bite Angle decreases to zero. In this way, the original of a discharge and crushing cavity into the crushing cavity, materials in the crushing cavity after being broken, from the discharge chamber, at this point, the material in a cross section of the rectangular prism shape, within the unit when asked by increase in the number of materials, production capacity is improved accordingly.
