Pearlite is a kind of acidic lava erupted from volcanoes. It is a glassy rock formed by rapid cooling. It is named for its pearl fissure structure. Pearlite raw sand can be used as filler in rubber and plastic products, pigments, paints, inks, synthetic glass, thermal insulation bakelite and some mechanical components and equipment after being superfine crushed by a superfine grinder.
Pearlite is expanded into a light and multifunctional new material. It has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide temperature range, low moisture absorption, non-toxic, odorless, fireproof, sound-absorbing, etc., and is widely used in various industrial departments.
Pearlite ore is mostly produced with bentonite, zeolite and other minerals. Due to the good zonation, it is easy to select and exploit. The mined ore has a single composition, and the separation workload is generally small. The main preliminary processing is crushing and screening, and the deep processing is the grinding process of perlite mill. The hardness of perlite is 5-6, and blasting is usually required during mining, and the larger size of the ore under blasting is generally not more than 20cm. This lump ore can not be used to directly burn expanded perlite. Therefore, the two processes of ore crushing and screening are indispensable. After the perlite is broken and ground, the particle size of the ore varies with the use and roasting process.
The grinding range of raymond mill of SMMVIK Machinery is between 80-400 mesh. The ultra-fine grinding machine can process perlite to 400-3000 mesh. There is no problem to grind perlite sand to 500 mesh.
Welcome the users who need to come to consult the perlite grinding machine and ultra-fine grinding machine. SMMVIK Machinery provides customers with a complete set of perlite processing production line and complete set of perlite grinding equipment. Now the production process of mobile grinding station is basically mature, and each mechanical manufacturer of mineral processing equipment can carry out production. When selecting and purchasing equipment, it is necessary to carry out field investigation, compare with other parties, and select manufacturers with strength and high cost performance.
