Granite introduction:

Granite, the main component of the continental crust, is a igneous rock formed by the condensation of magma below the surface, belonging to deep intrusive rocks.Granite is not easy to weather, beautiful in color, and its appearance can be kept for more than 100 years. In addition to being used as a high-grade architectural decoration, the hall floor, or the choice of open-air carving.Because granite is rarer than ceramics or other man-made materials, laying granite floors can greatly increase the value of large properties.Natural granite countertops have excellent temperature resistance and are the choice of all types of sheet metal processing.The granite structure is uniform, the texture is hard, the color is beautiful, and it is durable. It is a high-quality building stone and is known as the "king of rock".In the building, granite can be used from the roof to the floor. If it is crushed, it can be made into cement or rock-filled dam.

Granite processing:

The granite production line is mainly based on the actual size of the granite and the customer's requirements for product granularity,According to different production sites, Dewo provides process solutions and technical support to customers.It is also possible to design non-standard parts according to the actual installation conditions of the customer.

The processing of granite is divided into three stages: coarse crushing of jaw crusher, medium fine crushing of cone crusher and sand making of sand making machine.

The first stage: coarse crush

The granite bulk material is uniformly fed by the vibrating feeder through the silo, and conveyed to the jaw crusher for coarse crushing. After the coarsely crushed material is sieved by the vibrating screen, it is transported by the belt conveyor to the cone crusher to break and be finely crushed.

Second stage: fine crushing

After the granite conveyed to the cone crusher is finely crushed, it is sieved by a circular vibrating sieve, and the material of 40 mm or more is returned to the cone crusher to be broken again.

The third stage: sand making

The granite particles less than 40 mm after crushing are sent to impact crusher (sand making machine) for further crushing and shaping, and the material of 20 mm or more is returned to the sand making machine for fine crushing again. The material less than 20mm is sent to the circular vibrating screen for screening and packaging. If the granite needs to be cleaned, it can be sent to the sand washing machine for cleaning.


Applications in industries such as hydropower, highways, and urban construction. The granularity of finished products can be combined and graded according to the different needs of users.

Equipment configuration: 

vibrating feeder, jaw crusher, hydraulic cone crusher, sand making machine, vibrating screen, belt conveyor

Granite process technology:

The granite production line is launched by Dewo has high automation, high breaking rate, low operating cost, energy saving, environmental protection, uniform product size, good grain shape and reasonable grading.


Remarks:The production line is mainly based on the actual material size and the customer's requirements for product granularity. According to different production site conditions, Dewo engineers can provide customers with process planning and technical support, and we can also design non-standard according to the actual installation conditions of customers and supporting components, etc., we strive to achieve a reasonable and economical production line for customers.
