Granite rock because of the hard, difficult to be alkali or erosion, weathering granite, high strength, low crushing value, strong corrosion resistance, good asphalt adhesive is used widely in building stone, since it has the characteristics of porosity is much and hard, to be blended in concrete, can make the concrete weight, do not break again strong, has the advantages of sound insulation, heat insulation, at the same time become a high-rise building high-quality aggregate of lightweight concrete.
Granite crushing production process generally can choose two stage crushing process, first choose jaw crusher, granite material first by vibrating feeder evenly send to jaw crusher for coarse crushing processing, the second choice counterattack crusher, and then continuous, quantitative will be crushed by belt conveyor after further broken inside material into the counterattack crusher; Finely marble/granite particles through the sieve after the screen into different grades, you can use the circle vibrating screen screening out 1 to 2, 2-4, 4 to 8 different specifications of stones, meet the requirements of the material will be sent to the sand making machine sand integrity, unqualified material are back to the superior to broken; Finally, the sand from the sand making machine should be washed and cleaned by the washing machine, and the finished product can be obtained.
