Perlite grinding equipment

   

Perlite is a volcanic eruption of acidic lava. It is named after its sharply cooled vitreous rock due to its pearl-fracture structure. Perlite mines include perlite, obsidian and rosin. The difference between the three is that the perlite has a circular arc crack formed by condensation, called perlite structure, water content of 2 to 6%; rosin rock has a unique rosin luster, water content of 6 to 10%; black shale has glass Gloss and shell-like fractures, water content is generally less than 2%. Content from dedecms

The main purpose:

Perlite raw sand is crushed and ground by ultra-fine grinding machine, which can be used as filler in rubber and plastic products, pigments, paints, inks, synthetic glass, heat insulation bakelite and some mechanical components and equipment.

Perlite expands into a lightweight, versatile new material. It has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide temperature range, low moisture absorption capacity, non-toxic, odorless, fireproof and sound absorbing. It is widely used in various industrial sectors.

 

The working principle of perlite pulverizer and perlite grinding equipment:

During operation, the main motor 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 bulk material is broken into small particles by a hammer crusher and then sent to the storage bin by the hoist, and then passed through the vibrating feeder and the inclined feeding pipe to uniformly feed the material to the bulk disc of the upper part of the turntable. Dream weaving content management system

The material is scattered to the circumference of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, which is impacted, rolled and ground by the ring roller, processed into a powder through the processing of the three-layer loop, and the high-pressure fan passes the external air through suction. Inhaled into the machine and the pulverized material is brought into the classifier.

The impeller rotating inside the classifier re-grinds the coarse material, and the fine powder that meets the requirements enters the cyclone dust collector with the airflow and is discharged from the lower discharge valve, and the airflow with a small amount of fine dust passes. The pulse dust collector is purified and discharged through a fan and a muffler.

 

Processing materials:

Perlite grinding equipment can not only process perlite, but also ultra-fine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, such as calcite, chalk, limestone, dolomite, Carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alum, graphite, More than 100 kinds of materials such as fluorite, phosphate rock, potassium ore and pumice, the fine powder finished product can be arbitrarily adjusted between 15 and 3000 mesh, and the output can reach 0.5-12 tons per hour.

 


Perlite grinding processing equipment:

YGM high-pressure suspension roller Raymond mill : processing fineness between 15-425 mesh (fineness can be adjusted arbitrarily)

HGM three-ring medium-speed superfine mill
 : processing fineness between 325-3000 mesh (fineness can be adjusted freely)

Advantages of perlite pulverizer equipment : 

1. The high efficiency
In the case of the same fineness of the finished product and the same motor power, the output of the jet mill, the agitator mill and the ball mill is more than double.

2. The vulnerability of long service life
The grinding roller and the grinding ring are forged by special materials, so that the utilization degree is greatly improved. In the case of the same material and finished product fineness, the wear life of the impact crusher and the turbo crusher is 2-5 times longer, generally more than one year. When processing calcium carbonate and calcite, the service life can reach 2 -5 years. Dede

3. High safety and reliability
Since there is no rolling bearing or screw in the grinding chamber, there is no problem that the bearing and its sealing member are vulnerable, and there is no problem that the screw is loose and the machine is destroyed. 


4. Product fineness is high
The product fineness can reach D97≤5μm at one time. 


5. Environmental protection, cleaning 
The dust collector is used to capture dust, and the muffler is used to reduce noise. It is environmentally friendly and clean.
