Pumice is a kind of vitreous lava with dense pores formed by the rapid cooling of magma in the process of the volcanic eruption. Due to the sharp reduction of pressure, and the rapid overflow and expansion of internal gas. Its pore volume accounts for more than 50% of the rock volume.
It is called pumice because it has many pores, light weight, and can float on the water surface.
Pumice is characterized by high strength, heat preservation, heat insulation, sound absorption, fire resistance, acid and alkali resistance, corrosion resistance, and no pollution, no radioactivity, etc.
Pumice
Pumice processing equipment pumice mill pumice micro powder mill is a kind of high-efficiency and low-consumption ultra-fine powder processing equipment designed by the R & D Technology Department of Shanghai CLIRIK Machinery Co.,Ltd.
It has successfully replaced the complex procedures of traditional jet mill and ball mill grinding and powder selection, significantly reducing production costs and improving product fineness.
Thousands of domestic users have proved that this equipment has the advantages of superior performance, stable quality, simple operation, and convenient maintenance.
It is ideal equipment for ultra-fine pumice powder processing.
Pumice processing equipment micro powder mill
When the fineness of finished products and motor power are the same, the output is more than twice that of jet mill, stirring mill, and ball mill; 30% lower energy consumption.
The grinding roll and ring are forged with special materials, which greatly improves durability. With the same fineness of materials and finished products, the service life of vulnerable parts is 2-3 times longer than that of impact crusher and Turbine Crusher, which can generally reach more than one year; When processing calcium carbonate and calcite, the service life can reach 2-5 years.
Because there are no rolling bearings and screws in the grinding chamber, there is no problem that the bearings and their seals are vulnerable, and there is no problem that the screws are easy to loosen and damage the machine.
The fineness of Raymond mill and other rough grinding products is 325 mesh (47 microns). Compared with this, the fineness of the finished products processed by this ultra-fine mill can be adjusted arbitrarily between 325 mesh and 2500 mesh (47-5 microns), and the fineness can reach D97 ≤ 5 μm at one time.
The pulse dust collector is used to capture dust and the muffler is used to reduce noise, which is environmentally friendly and clean.
With this device, the particle size of the processed powder is more uniform and easy to adjust.
Pumice processing equipment micro powder mill is mainly applicable to the processing of ultra-fine powder of nonflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as pumice, calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite Fluorite, phosphate rock, potassium ore, pumice and other more than 100 kinds of materials.
The particle size of the finished fine powder is arbitrarily adjusted between 325-3000 mesh, and the output can reach 0.7-7.5 tons per hour.
There are five models of HGM series ultra-fine grinding machines of Shanghai CLIRIK Machine Co., Ltd. : HGM80, HGM90, HGM100, HGM125 and HGM1680.
Pumice processing equipment micro powder mill complete configuration, including 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.
After large materials are crushed into small particles by the crusher, they are sent to the storage bin by bucket elevator, and then evenly sent to the bulk tray on the upper part of the turntable in the main machine through the vibrating feeder and the inclined guide pipe.
When the pumice grinding mill is working, the main motor drives the main shaft and rotary table to rotate through the reducer, and the rotary table drives dozens of grinding rollers to rotate and roll in the grinding ring raceway through the roller pin on the edge.
Under the action of centrifugal force, the materials scatter to the periphery, fall into the magic cavity, and are impacted, rolled and ground by the grinding roller in the ring path of the grinding ring.
It is repeatedly ground into powder through three or four layers of loops.
The high-pressure fan sucks the external air into the machine through suction and brings the crushed materials into the powder concentrator.
The high-speed rotating impeller will screen it, the unqualified coarse powder will fall back and Regrind and the qualified fine powder will enter the cyclone powder collector with the airflow.
The dust will fall and be discharged by the discharge valve at the bottom, which is the finished product.
A small part of the fine dust enters the dust collector with the airflow and adheres to the surface of the filter bag.
The pulse valve controls the high-pressure airflow to spray from the inside of the filter bag instantly, and the dust adhered to it will fall due to the sudden shaking of the filter bag.
The conveyor at the bottom will send the fine powder materials collected at two places out for finished product packaging. The filtered clean air is finally discharged at the outlet of the muffler.
