1. Granite grinding use

(1) Granite has different uses according to the size of the grains: fine grains can be polished or carved as decorative plates or works of art; medium grains are often used to build bridge piers, bridge arches, dams, harbors, pavements, etc.; The coarse grains are rolled into crushed stone, which is an excellent aggregate for concrete.

(2) Granite grinding powder can be used as an inert stone powder, which can be mixed into concrete to change its working performance. It is feasible to mix inert stone powder with mineral powder, which can take into account the economy and concrete work performance, strength and durability. The mixing of inert stone powder and fly ash has a great influence on the strength, carbonation resistance and chloride ion penetration resistance of medium and low grade concrete.

(3) Granite grinding powder and limestone, sodium carbonate, sodium sulfate, carbon and zinc oxide are used to prepare glass batches to prepare columnar-wollastonite glass-ceramics, which can be used in building decoration materials. Granite waste and limestone, dolomite and alumina are prepared with different components, and glass-ceramics with different decorative patterns can be obtained.

(4) The main components of granite include feldspar, quartz and biotite. The use of granite stone solid waste sawing mud and stone powder to prepare ceramic raw materials, on the one hand, fundamentally solves the industrial problem of stone sawing mud polluting the environment and wasting resources, and at the same time using renewable resources to replace primary ores, solving the problem of raw material supply in the ceramic industry. In addition, granite stone powder can also replace fly ash for mineral powder production, artificial stone and so on.

2. Granite grinding equipment

Guilin Hongcheng HLM vertical mill has introduced foreign advanced technology and innovatively developed a high-efficiency grinding equipment integrating crushing, drying, grinding, grading and conveying, which can be used for granite grinding. At the same time, it is widely used in electric power, metallurgy, cement, chemical industry, non-metallic minerals and other industries, mainly used for cement raw meal, clinker, power plant desulfurization limestone powder, slag, steel slag, manganese ore, gypsum, coal, barite, calcite, Bauxite and other materials are ground for processing. It has the advantages of low cost, high efficiency and large output. Production capacity: 1-200t/h, finished product particle size: 22-180μm.
