Perlite is a kind of volcanic eruption acid lava, vitreous rock formed by rapid cooling, it is a kind of white granular material with honeycomb structure. Perlite mines include perlite, obsidian and turpentine. The principle of perlite is that the perlite ore is crushed to form ore sand of a certain size, after preheating roasting, rapid heating, the water in the ore is vaporized, and it expands inside the softened vitreous ore to form a porous structure with a volume expansion of 10-30 times of non-metallic mineral products.
Perlite is brittle, expands when exposed to heat, but does not shrink when exposed to cold. It has pearl luster and grease luster, special arc-shaped cracks and fire resistance. It can be made into perlite products, with light weight, low thermal conductivity, strong sound absorption, non-corrosive, non-burning, acid-base, non-toxic and odorless, and is a high-efficiency and ultra-light thermal insulation, heat insulation, and sound insulation, decoration materials.
Fighter raymond mill has obvious advantages, performance characteristics, scientific and reasonable structure, and is widely used in the field of perlite grinding processing by virtue of advanced milling technology. It is a common equipment for perlite processing, the fineness of the finished product can be adjusted between 80-400 mesh, the output is 30%-40% higher than the traditional mill, and the energy consumption is greatly reduced.
Number of grinding rollers: 3-5
Feeding size: 30mm
Finished product output: 1-25t/h
Product fineness: 0.022-0.18mm
Application scope: This mill can be widely used in metallurgy, chemical rubber, coatings, plastics, pigments, inks, building materials, medicine, food and other processing fields. The grinding effect is significant, and the technical level is leading domestically. It is an ideal equipment for non-metallic mineral processing.
Application materials: High-yield and efficient processing of non-metallic minerals such as bauxite, titanium dioxide, ilmenite, phosphate rock, clay, graphite, calcium carbonate, barite, calcite, gypsum, dolomite, potash feldspar, etc. The fineness adjustment is convenient and the operation is simple.
Grinding characteristics: The mill effectively increases the unit output of a single device and reduces the energy consumption per unit output. It has the technical advantages of wide use, simple operation, convenient maintenance, stable performance, high efficiency, environmental protection and high cost performance.
