There are several characteristics to consider:

The abrasiveness and hardness factor. It is essential to know what material is going to be crushed, in particular its abrasiveness and hardness. You must evaluate the compressive strength or maximum force that the material can withstand before breaking.
The dimensions. You will need to consider the maximum dimensions you need to enter into the machine (length, width and thickness).
Granulometric requirement. It is necessary to define the desired result i.e. the grain size after crushing.
The capacity (throughput). You will need to determine the processing capacity (or throughput) necessary for your use. This is measured in tonnes/hour.

The jaw crusher crushing capacity is relatively large, and feed inlet is large, so widely used to crush large stone or mineral. Such as pebbles, granite, marble, basalt, limestone, gold, silver, lead, zinc, hematite, manganese, copper and so on.

Jaw liners are normally Mn-steel liners with 11-18 % Mn to withstand impact and abrasion resistance. With proper selection and design of the system, the life of jaw plates may be enhanced. Preferably discharge height should be optimum and jaw lines should be such that it can be repositioned so that the wearing of jaw plate s more uniform before discarding.

While stationary crushers have the advantage of being sturdy, it can be advantageous to choose a mobile crusher to get the crusher closer to where the it is going to be needed. Wheeled crushers can be moved to a construction site using a truck. These units are generally autonomous and therefore do not require an additional diesel engine to operate. Mobile crushers perform the same types of crushing as stationary ones. For reasons of autonomy, they also include a hopper and a conveyor to feed the crusher, as well as a second conveyor to evacuate the final product.
