Perlite: A special variant of acidic extrusive rock, a volcanic eruption of acidic lava, a vitreous rock formed by rapid cooling, named for its pearly fissure structure. It is characterized by the presence of spherulites or a large number of pearly cracks in the acid volcanic glass matrix. Perlite mines include perlite, obsidian and turpentine.
Perlite is brittle, expands when heated, but does not shrink when cold. It has pearl luster and grease luster, has special arc-shaped cracks, and is fire-resistant. Perlite has the properties of light weight, low thermal conductivity, strong sound absorption, no corrosion, no combustion, acid and alkali resistance, non-toxic and tasteless, etc. It is a high-efficiency and ultra-light heat preservation, heat insulation, sound insulation and decoration material.
The HGM series ultra-fine grinding mill produced by SBM can grind perlite into fine powder of about 2500 mesh, which can be used as filler in rubber and plastic products, pigments, paints, inks, synthetic glass, heat-insulating bakelite and some mechanical components and equipment.
Mainly suitable for superfine powder processing of non-flammable and explosive brittle materials with medium and low hardness, Mohs hardness ≤7, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, barite, gypsum, graphite, fluorite, phosphate rock, potassium ore, pumice and more than 100 kinds of materials. The particle size of the finished fine powder can be adjusted arbitrarily between 150-3000 mesh, and the output can reach 0.4-45 tons per hour.
● High economic benefits
Three-dimensional structure, small footprint, strong complete set. From the block to the finished powder, it forms a self-contained production system with less one-time investment. Low energy consumption. Under ideal working conditions, the energy consumption per unit of throughput and the unit energy consumption of new feeding materials are 1.02kWh/t and 1.48kWh/t respectively, which is more than 60% lower than the power consumption required by ball mills of the same level.
● Better stability
The main engine, powder separator and fan are softly connected, which reduces vibration and noise, avoids the damage to the equipment caused by resonance, and also avoids the impact on the quality of the finished product. The large, inclined air duct is adopted to ensure that the wind entering the air inlet volute can smoothly blow into the grinding chamber of the main engine along the inclined plane.
● More convenient operation
The convenient and quick impeller adjustment device is adopted, so that the size of the gap between the blade end of the powder separator and the shell can be adjusted conveniently and quickly. The equipment is easy to operate, and one person can easily operate it.
● Grind more fully
Compared with the traditional Raymond mill, the grinding roller and the grinding ring are designed in a multi-step ladder shape, which reduces the sliding speed of the material between the trapezoidal grinding roller and the grinding ring, prolongs the rolling time of the material, and improves the finished product. fineness and yield.
● Higher rolling pressure
Drawing on the advantages of Raymond mill and suspended roller mill, the grinding roller assembly is connected together by tie rods and horizontally placed springs. With the combined action of centrifugal force, the material is fully squeezed, thereby increasing the output.
● High level of environmental protection
The main engine and the powder separator adopt a soft connection, and the shock-absorbing spring and the sealing belt not only reduce the vibration and noise, but also avoid the resonance. The production line can be equipped with dust removal equipment to ensure that dust pollution is reduced to a minimum.
When working, the main motor drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.
The bulk materials are crushed into small particles by the hammer crusher, and then sent to the storage bin by the elevator, and then sent to the bulk tray on the upper part of the turntable evenly through the vibrating feeder and the inclined feeding pipe.
The material is scattered to the periphery of the circle under the action of centrifugal force and falls into the raceway of the grinding ring. It is impacted, rolled and ground by the ring roller. It is sucked into the machine, and the pulverized material is brought into the classifier.
The rotating impeller in the powder separator makes the coarse material fall back for regrinding, and the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the lower part of the powder separator, which is the finished product, while the airflow with a small amount of fine dust passes through After the pulse dust collector, it is discharged through the fan and the muffler.
The pulverizer production line usually includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-powder mill host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high pressure fan, air compressor, electrical control system, etc.
① Comprehensive investment cost is low
It has comprehensive mechanical crushing properties such as rolling, grinding and impact, and can be applied to various non-mineral fine powder processing markets with Mohs hardness below 7 and humidity within 7%. Small footprint, strong complete set, and low comprehensive investment cost.
② Small wear and low noise
The grinding wheel and grinding ring are made of special wear-resistant steel, and the whole machine has a long service life.
③ Compact structure and layout
The base of the main engine adopts an integral casting structure, which not only ensures a compact structure, but also has good shock absorption performance.
④ The grading accuracy is uniform and fine
The forced turbine grading system is adopted, the particle size is more uniform and finer, and the finished products of different fineness can be applied to different market demands and enhance the market competitiveness.
⑤ The crushing ratio of the whole machine is large, and the energy utilization rate is high
It has the advantages of high output and low speed, and the product fineness can reach D97≤5μm at one time.
⑥ High dust collection efficiency
Equipped with a full pulse dust collection system, the dust collection efficiency is as high as 99%, and the entire operation workshop is clean and tidy. It is a fine powder processing production line that is environmentally friendly and reduces consumption.
