What is the Perlite Micropulver mill

Perlite is a vitreous rock formed by the rapid cooling of acid rocks erupted by volcanoes. After the perlite is calcined at high temperature, the volume expands rapidly by 4-30 times, and numerous glassy closed pores are formed in the rock. This finished product is called expanded perlite. After the perlite mining has been processed by different crushers and micro-grinding equipment, different fineness perlite powder is widely used in construction, energy-saving petroleum, chemical, pharmaceutical, sewage treatment, and agricultural sectors. Shuguang Heavy Industry specializes in the production of perlite crushers, perlite fine powder and micro-grinding.

Working principle of perlite powder micro-grinding equipment: When working, the main motor of the grinding equipment drives the main shaft and the turntable through the reducer, and the roller pin on the edge of the turntable drives dozens of grinding rolls to roll in the grinding ring raceway. The perlite ore is broken into small particles by a hammer crusher and then sent to the storage bin by the hoist. Then, through the vibrating feeder and the inclined feeding pipe, the perlite particles are evenly sent to the bulk tray of the upper part of the turntable. on. The perlite particles are scattered to the circumference of the circle under the action of centrifugal force, and fall into the raceway of the grinding ring, which is impacted, rolled and ground by the ring roller. After three layers of loop processing, it becomes perlite powder, and the high pressure fan passes the suction effect. The outside air is drawn into the machine, and the pulverized perlite powder is brought into the classifier. The impeller rotating inside the classifier re-grinds the coarse perlite powder, and the fine powder that meets the requirements enters the cyclone dust collector with the airflow and is discharged from the lower discharge valve to be the final perlite ultrafine powder. The airflow with a small amount of fine dust is purified by a pulse dust collector and then discharged through a fan and a muffler.

Performance characteristics of perlite powder grinding equipment: 1. Efficient in the case of fine pearlite powder fineness and motor power, the output of perlite powder grinding equipment is more than double that of jet mill and ball mill; Long service life The grinding roller and grinding ring are forged with special materials, which greatly improves the durability. In the case of the same fineness of the material and the finished product, the wearing parts of the perlite fine powder micro-grinding are 2-3 times longer than the wearing parts of the impact crusher and the turbo crusher, generally up to one year; The grinding equipment can process the calcium carbonate, perlite, calcite, the service life can reach 2-5 years; 3. The safety and reliability are high. There is no rolling bearing and screw in the grinding cavity, so there is no problem that the bearing and its seal are vulnerable. , or the problem of destroying the machine due to the looseness of the screw; 4. The fineness of the product is high. The fineness of the perlite powder processed by the grinding equipment can reach D97 ≤ 5μm at one time; 5. In the environment of small dust grinding equipment The use of environmentally-friendly pulse dust collectors and mufflers greatly reduces dust and noise pollution to the surrounding environment.
