After crushing perlite, may be made of insulating material. Perlite ore includes perlite, obsidian rock and turpentine. Difference between the three is perlite having a circular arc-shaped cracks formed due to condensation, said perlite structure, water content of 2 to 6%; turpentine rock has a unique turpentine gloss, water content of 6 to 10%; obsidian having a glass luster and conchoidal fracture, the water content is generally less than 2%. Perlite is widely used, the original sand by fine grinding and ultrafine grinding, can be used in rubber products, pigments, paints, inks, synthetic glass, bakelite insulation and some mechanical components and equipment for filler. The expanded perlite and become a lightweight, multi-functional new material, with an apparent density of light, low thermal conductivity, chemical stability, wide temperature range, low moisture absorption, and non-toxic, odorless, fire, acoustic, etc. It is widely used in many industrial sectors.
Expanded perlite is what we often see a perlite, which is acidic volcanic eruption rock product. The production process can be divided into expanded perlite crusher crushing, screening, preheating, rapid heating (1260), cooling and other processes, foremost of which is broken, preheating and firing three steps. The production of expanded perlite, ore roasting process requires uniform particle size. 0.15-0.5mm size is generally appropriate, particles are too large, too small will affect the baking results. When firing a particle size selection by the user of the roasting process and product requirements, the production of light, when the expanded perlite insulation, particle size 0.15-0.6mm appropriate expansion works best. Our company specializes in mining machinery manufacturing for decades, has a wealth of manufacturing experience, can provide a full perlite expanded processing plant production line, also produces crushing equipment, milling equipment, building materials and equipment, such as jaw crusher, cone crusher , mobile crushing plant, Raymond mill, welcomed the commitment mining industry friends call us to buy.
Our research and development of perlite expanded processing plant includes feeder, jaw broken, crushing machine, vibrating screen, bucket elevator, belt conveyor and centrally electric control and other equipment, according to the different degree of processing of perlite, perlite ore and its products can be divided into , perlite ore, perlite and expanded perlite four types of surface treatment. Since the purpose of perlite ore beneficiation selected ore is processed into particle size, moisture and other indicators have reached the requirements of industrial product, perlite ore, perlite and thus determine the beneficiation process is very simple, usually crushing, grading, drying.
Our latest development of perlite aggregates production line is a set of perlite expanded processing plant production line equipment specially designed for the perlite, the production line in the case of producing the same quality than the previous gravel production line output can be increased by 20% each term performance has been greatly improved. Here we remind you that the company's R & D personnel, in the production of perlite aggregates production line due to the fragile characteristics of perlite, wrong mode of production will produce large amounts of tailings, the tailings have many uses, such as perlite, used in the manufacture of tailings ceramic, foam glass, porous sintered material, firefly screen abrasive, casting surface coating agent.
