Granite has hard and dense texture, high strength, weathering resistance, corrosion resistance, wear resistance, low water absorption, beautiful color can be preserved for more than a hundred years, is a good building material. Due to its high hardness, wear resistance, in addition to use as a senior building decoration engineering, hall ground, or the first choice of open-air carving material.

Granite is a kind of widely used building material, and its resources have the advantages of rich storage,wide distribution and variety.Folk tradition USES granite to build houses, roads and Bridges.Granite belongs to a special ore with high quartz content and little iron
Material handling process
In the process of crushing and processing, granite can be divided into three stages: coarse crushing of jaw crusher, medium and fine crushing of impact crusher or cone crusher, and sand shaping of sand making machine.The specific processing technology is as follows:
First of all, the mining of natural granite by vibrating feeder evenly send to the jaw crusher for early break, after the early broken by vibrating feeder sent to the cone crusher for the second, moreover, after the second granite particles was sent to the circular vibrating screen for screening, unqualified size be returned to cone crusher broken, granularity of qualified granite by screen is divided into different levels according to the particle size, and then be sent to the corresponding product heap;Finally, if a finer product or shaping is needed, the crushed material will be sent to the sand making machine for further crushing and shaping. If the clean granite stone is needed, it can be sent to the sand washing machine for cleaning.
