Which crusher equipment is used to crush hard rock?

Rock is an ore material that can be seen everywhere in nature, so how to distinguish hard rock? Generally, it can be judged by the saturated uniaxial compressive strength. Rocks greater than 60MPa are called hard rocks, and those between 30-60MPa are harder rocks. For example: granite, basalt, limestone, marble, sedimentary rock, quartzite, slate, dolomite, limestone, gneiss, etc. are all called hard rock, which can be used well after crushing and sand making. To roads, bridges, municipal construction, airport runways, railways and many other fields. But if you want to process it, you need to use a crusher. Only the materials processed by the crusher can be used in the construction industry. In general, the processing of rocks can be roughly divided into three steps: coarse crushing, medium crushing and fine crushing. The following will be some introductions to the hard rock crusher, hoping to be a reference for the user's later investment and purchase.
If it is a large piece of rock, it needs to be coarsely crushed first. In this process, the jaw crusher in the crusher is generally used, also referred to as jaw crusher. Jaw crusher is the preferred equipment for rough rock crushing. The JC series jaw crusher produced by Zhejiang Lizhi Machinery has a unit production capacity of up to 1500t/h, and the maximum feed size can also be arbitrarily selected between 430~1360mm, etc. . It has the following advantages:

1. Jaw crusher is suitable for rough crushing of various soft and hard ores with compressive strength not higher than 300MPa (Mpa);

2. The jaw crusher has a wide adjustment range for the discharge opening, and the wedge-type discharge opening adjustment structure realizes stepless adjustment, which is simple and fast to meet the requirements of different users.

3. The "V" cavity design makes the crushing efficiency higher, the output is larger, the crushing ratio is large, and the product size is uniform.

4. There is no dead zone in deep cavity crushing, and the material will not be blocked in the crushing cavity, which improves the production efficiency.

5. The integrated installation structure of the main engine and the motor makes the basic handling simple.

6. The large inclination angle bracket design makes the lower stroke of the cavity larger and higher output.

7. The jaw plate can choose different tooth shapes according to the different materials to be crushed to make the crushing effect better.

8. The integral cast steel bearing seat structure is convenient for transportation and installation, and the bearing runs more smoothly.
