Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granite usually has a medium- to coarse-grained texture. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic. Granite is nearly always massive (lacking internal structures), hard and tough, and therefore it has gained widespread use as a construction stone.
ball mill for granite
Ball mill is traditional and common grantie grinding machine. Ball mill now has been widely used in electric power, mining, metallurgy, chemicals, iron and steel, building materials, coal and other industries. It has made huge economic and social benefits. It is high technology, more advanced, more reliable, more efficient than other traditional grinding mills.
granite grinding process
Raw granites first enter jaw crusher to be crushed to smaller size. Then they are lift to storage room by elevator. Vibrating feeder will feed materials into grinding chamber evenly and gradually. After being grinded, the granite powder will be blowed to cyclone by blower. Then the granite powder will be transferred to storage room through pipes, and then will be discharged as final products.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
