The main component of the granite continental crust is an igneous rock formed by the magma condensing below the surface. The main components are feldspar, mica and quartz. Granite texture is hard and dense, high strength, weather resistance, corrosion resistance, abrasion resistance, low water absorption, beautiful color and luster can be preserved for more than 100 years, it is a good material for construction, but it is not heat resistant due to its high hardness and wear resistance Damage, in addition to being used for building decoration works, hall floors, is also a common choice for open-air carving.

Granite can be used in the building from the roof to the floor. If it is crushed, it can be made into cement or rock-filled dams. Granite is not easy to weather, the color is beautiful, and the appearance and color can be maintained for more than 100 years. In addition to being used as high-end architectural decoration and hall floor, it is also the material of choice for outdoor carving. Because granite is rarer than ceramics or other man-made materials, laying granite flooring can greatly increase the value of large real estate, and natural granite countertops have unique temperature resistance, which is the choice for various types of board processing.
Granite crusher plant
Granite is relatively hard but has a certain degree of brittleness. Compared to basalt, granite is easier to break; compared to medium hardness materials such as limestone, granite is more difficult to break. Therefore, in the process design of the granite crushing production line, the crushing equipment of the lamination principle is selected as much as possible to reduce the wear of the wear-resistant parts. For short and medium-term projects, two-stage crushing can be used; for medium- and long-term projects, three-stage crushing is an ideal choice.
If the customer has higher requirements on the final stone particle size, a counter-impact or impact crusher can be configured for integral crushing to form a three-stage crushing process configuration. Three-stage crushing has a higher investment cost, but for long-term operation of sand and stone plants, three-stage crushing has an advantage.
Granite aggregate crushing plant
Granite is an excellent raw material for gravel aggregate, and it is the preferred raw material for the high-grade stone.
For small and medium-sized granite crushing production lines, the process configuration of jaw crushing + impact crushing can be adopted. Jaw crushing should reduce the granularity of granite as much as possible, and the impact crusher will shape the crushing, so as to achieve the crushing effect of excellent particle size and appropriate control of low wear cost.
For a large-scale granite crushing production line, a three-stage crushing process should be used as much as possible. The jaw crushing + fine jaw crushing (or cone crushing) + impact crusher process configuration can be used. The power consumption and wear cost of the laminated secondary crusher are relatively low, but the investment cost is relatively high.
For granite crushing production line with low grain size requirement, it can be prepared by a two-stage jaw crusher process. Although the grain shape is poor and the proportion of needle-shaped stone is high, it can greatly reduce the running cost and investment cost. The sales price of sand and gravel with poor grain types will also be affected to some extent.

Granite crushing process flow
The first stage: coarse crushing
Large pieces of granite material are evenly fed by the vibrating feeder through the silo, and then conveyed to the jaw crusher for coarse crushing. The coarsely crushed material is screened by a vibrating screen and then conveyed by a belt conveyor to an impact crusher or cone The crusher performs fine crushing.
The second stage: medium fine crushing
After the granite conveyed to the impact crusher / cone crusher is finely crushed, it is sieved with a circular vibrating screen. Larger particles are returned to the impact crusher / cone crusher and broken again.
The third stage: sand making
The crushed granite is sent to the sand making machine for further crushing and shaping. If clean granite is required, it can be sent to a sand washing machine for cleaning.
The fourth stage: packaging
Pack and store the finished product after drying.
