Granite is a kind of tectonic rock formed by the volcanic eruption of lava uplifted to the surface of the earth's crust in a molten state under considerable pressure, and the magma does not eject out of the ground, but slowly cools and solidifies underground. Granite is mainly composed of quartz, feldspar and mica. Among them, the feldspar content is 40%~60%, and the quartz content is 20%~40%, and its color is determined by the type and quantity of the components contained. The rock is hard and compact.

Introduction to granite sand making machine equipment

In recent years, the rapid development of the construction industry has made the sand making machine an essential equipment for the artificial sand making industry, and has attracted much attention in the mining industry.

Granite crushing solutions

The first stage: the coarsely crushed granite bulk material is evenly fed by the vibrating feeder through the silo, and transported to the jaw crusher for coarse crushing, and the coarsely crushed material is screened by the vibrating screen and transported by the belt conveyor to the impact crusher or cone crusher for medium and fine crushing. The second stage: the granite conveyed to the impact crusher/cone crushing is screened by the circular vibrating screen after medium and fine crushing, and the larger particles are returned to the impact crusher/cone crusher for crushing again. Because granite is a plutonic rock, it often forms well-developed mineral particles that are recognizable to the naked eye, hence the name. Granite is not easy to weather, the color is beautiful, the appearance of the color can be maintained for more than 100 years, because of its high hardness, wear resistance, in addition to being used as a high-level architectural decoration project, hall floor, but also the first choice for open-air carving.

Performance advantages of granite sand making machine

The granite production line is mainly composed of feeder, jaw crusher, impact crusher, sand making machine, vibrating screen, belt conveyor and centralized electronic control equipment, the whole production line in addition to the equipment on/off and maintenance needs labor costs, greatly reduce production costs, large output, low energy consumption, excellent finished product shape, in line with high-speed material requirements.

Low maintenance - the top cover adopts a rotatable structure, which is convenient for the inspection and maintenance of the sand making machine, and the material self-lining in the impeller and vortex crushing chamber greatly reduces the cost of wear parts and maintenance workload.

Stable operation - to reduce the vibration that may be generated by the frame and motor during the working process of the sand making machine, and a rubber shock absorption device is installed in the main frame and rotor cavity.

Low pollution rate - during the use of the "iron pollution" problem in the crushing process of glass and other raw materials and the "stuck steel" problem in the process of steel slag crushing in parallel with the solution, the ingenious internal air flow self-circulation eliminates dust dispersion.

Low investment, high recovery - the impact sand making machine has a high degree of production automation, low energy consumption, large crushing ratio, short payback period, and can recover the investment in 4-5 months.

The structure is unique and reasonable - the chassis and frame of the body of the impact sand making machine are all made of steel plate and adopt welded structure, and the advantages of the welded structure are light weight, large impact load, short manufacturing cycle, and more favorable to large-scale single-piece manufacturing.

High work efficiency - the use of wear-resistant lining plate instead of sand bed crushing can increase crushing efficiency and improve sand yield. The Germany sand making machine offers two options, and the user can achieve a quick changeover in one machine according to their needs.
