Wide Application
Perlite belongs to the acidic lava and it is formed after a period of rapid cooling. It is named because of its pearl fissure structure. Perlite ore includes perlite, obsidian rock and turpentine. The difference between the three perlites is the circular arc cracks formed by the condensation effect, which can be recognized as the perlite structure. It has water content of 2 ~ 6%; Pitching stone has a unique resin gloss, water content of 6 ~ 10%; Black obsidian with vitreous luster with conchoidal fracture, and it generally has less than 2% moisture content.
The Mohs hardness is 5.5-7 and the density is 2.2-2.4 g/cm3. The refractoriness temperature is 1300~1380°C.
Raw perlite materials will be processed through fine crushing and super fine crushing and it can be used for rubber and plastic products, paint, paint, printing ink, synthetic glass, heat insulation bakelite and some mechanical components and equipment for filling material.
After expansion, the perlite will be a kind of light, multi-functional new material. It has light apparent density, low thermal conductivity, good chemical stability, wide range of temperature, moisture absorption ability of small, non-toxic, tasteless, fire prevention, sound-absorbing characteristics. It is widely used in various industrial sectors.
Depending on the different processing stage, the product can be divided into crude perlite, perlite ore, expanded perlite and surface treatment of expanded perlite. As a result of perlite ore beneficiation aims to selected ore grain size, water content of the processed into indexes meet the requirements of industrial products, namely perlite ore, thus determines the perlite ore dressing process is very simple. It general refers to the crushing, grinding and drying.
The whole perlite processing plant mainly refers to the raw perlite ore materials mined - coarse crushing - screening - medium crushing - screening - fine crushing and fine ore tailings.
Perlite ore processing plant begins with the vibrating feeder. This feeding machine will take the raw extracted materials evenly to jaw crusher for the primary crushing stage. Large scale perlite rocks will be crushed into small size. Belt conveyor will take these materials into cone crusher or hammer crusher for the secondary crushing. For perlite's hardness, SBM experts suggest the VSI crusher is available. Vibrating screen is used to separate the large size rocks and then belt conveyor will sent these materials into crusher to be processed again till the material reach the desired size.
Then the ball mill will grind these crushed perlite ore raw materials into ultrafine size. The function of beneficiation equipment is to remove the impurities from perlite ore. According to different weight, you can utilize the gravity separator to remove the undesired materials. Also the magnetic separator will eliminate the magnetic materials from perlite ore. At last, through smelting, the high grade and pure perlite ore can get.
SBM will offer the high quality crushing machine jaw crusher for the perlite mining operators. Perlite jaw crusher has incorporated the best of the old production experience and applied the latest technology. The frame consists of two side plates of rolled steel, plus hollow castings at front frame end and moving jaw which give a high rigidity ratio. Large-radius transition areas reduce stress concentrations and welds are positioned in low-stress areas. The advantage of a welded frame is that it is equally strong in all directions and ensures excellent durability against shock-loads.
Perlite ore hammer crushers for fine and secondary crushing and it is designed with reverse operation of the rotor and hammers. The design of the inlet chamber, rotor with staggered hammers and smooth grate surface have a favorable influence on the crusher capacity.
Raymond mill is used for grinding the barite, limestone, kaolin, ceramics, and slags in the trades of mining, metallurgical industry, chemical engineering industry.
Mobile cone crusher is suitable for secondary and tertiary crushing in direct feed applications.
MTM Medium Speed Trapezium grinder is a kind of leading-world-level industrial milling machinery.
