Granite processing technology

Granite processing technology

Granite is an intrusive rock in magmatic rocks. This is the most common type of rock in this type, and is mostly light-red, light-gray, and gray-white. Granite can also be further named according to the dark mineral species. Mohs hardness is generally 6-7, which belongs to medium hard stone. Granite gravel due to the hard texture, difficult to be acid and alkali or weathering erosion, granite high compressive strength, low crushing value, corrosion resistance, asphalt adhesion and other characteristics are widely used building stone, due to its porosity And the hard characteristics, blending it in the concrete can reduce the weight of the concrete without losing the firmness. At the same time, it has the advantages of sound insulation, heat insulation, etc., and becomes a high-quality aggregate for high-rise building lightweight concrete. Granite stones can be used to make mortar and concrete, depending on the stone specifications. Stones 1-2, 2-4, and 4-8 are common stone specifications. China’s infrastructure construction cannot be stopped. The domestic granite stone market has always been extremely popular.

The Shanghai SBM mining machine uses a unique processing process in the production of granite to make granite utilization above 95%. Reducing the waste of raw materials significantly increases production capacity. Shanghai SBM Mining Machinery Co., Ltd. in the granite crushing production process can generally use two-stage crushing production process, the first stage selection jaw crusher, granite material is first sent to the jaw crusher by the vibrating feeder evenly crushing process In the second stage, the crusher is selected to sand making machine. After that, the crushing material is continuously and quantitatively transported by the belt conveyor into the impact crusher for further crushing; the finely divided marble/granite particles are screened into different grades by the vibrating screen. You can use a vibrating sieve to separate 1-2, 2-4, and 4-8 stones of different specifications. The material that meets the requirements will be sent to the sand in the sand making machine. Unqualified materials will be sent back to the higher level to continue. Crushing; Finally, the sand from the sand making machine is washed and removed by the sand washer to obtain high-quality finished products.

SBM mining machine jaw crusher with feed size of 125mm to 750mm is the primary equipment for primary crushing.

sand making machine
  • 1. The processing capacity is large and the particle size is uniform.
  • The crushing cavity is deep and has no dead zone, which improves the feeding capacity and output, and has a large crushing ratio and uniform product particle size.

  • 2. Low maintenance cost, safe and reliable.
  • Gasket-type discharge port adjustment device is reliable and convenient, with large adjustment range, increased flexibility of equipment, safe and reliable lubrication system, convenient component replacement, and low maintenance workload.

  • 3, low operating costs, system energy.
  • The structure is simple, the work is reliable, the operation cost is low, the single machine energy saving is 15% to 30%, and the system energy efficiency is more than doubled.

  • 4. Special consumables, long service life
  • The jaw plate is made of ZGMN13 manganese steel to make it more rugged and wear-resistant. The body of HT200 cast iron material is more comprehensive in protection of the main body of the elbow, and lubrication of the body grease is more convenient.

Shanghai SBM Mining Machinery Co., Ltd. is a professional crusher manufacturer. The SBM mining machine has been focusing on the production and manufacturing of mining equipment for 20 years. It has continuously introduced foreign advanced technology to integrate research and development to produce a company-specific quality product. SBM Raymond Mill, European mill, ultra-fine mill, high-pressure mill are sold at home and abroad and signed a contract with a number of companies, the annual sales reached more than 500 units.
