Special grinding machine for ultrafine mica powder
Product features: Good stability, high reliability, advanced technology, long service life, easy maintenance. Product description: Mica is a rock form
Product details
Mica is a rock forming mineral, typically in the form of pseudo hexagonal or rhombic plate-like, flaky, or columnar crystal shapes. Ultra fine mica powder can be used as functional filler for plastics, coatings, paints, rubber, etc., to improve its mechanical strength, enhance its toughness, adhesion, anti-aging and corrosion resistance. In addition to high electrical insulation, resistance to acid and alkali corrosion, elasticity, toughness and sliding properties, heat resistance and sound insulation, and low coefficient of thermal expansion, the two surfaces of the sheet are smooth, with a large diameter to thickness ratio, regular shape, and strong adhesion. In industry, it is mainly used as an insulation material for electrical equipment and electrical devices due to its insulation and heat resistance, as well as its resistance to acid, alkali, pressure, and delamination; Secondly, it is used to manufacture furnace windows and mechanical parts for steam boilers and smelting furnaces. Ultra fine mica powder can be processed into mica paper, and can also replace mica sheets to manufacture various low-cost and uniformly thick insulation materials.
muscovitepulverizer- Ultra fine mica powderGrinding machine:
HGMSeries MicapulverizerMainly suitable for ultrafine powder processing of non flammable 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, zeolite, gypsum, alum, graphite, fluorite, phosphate rock, potassium ore, pumice and more than 100 other materials. The particle size of fine powder products can be adjusted freely between 325-3000 mesh, and the output can reach 0.5-12 tons per hour. HGM series micapulverizerIt is a specialized tool for processing ultrafine mica powderGrinding machine.
muscovitepulverizerComposition:
muscovitepulverizer- Ultra fine mica powderGrinding machineThe complete configuration includes a hammer crusher, bucket elevator, storage bin, vibrating feeder, grinding machine host, variable frequency classifier, dual cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, and electrical control system.
muscovitepulverizerWorking principle:
During work, micapulverizerThe main motor drives the spindle and turntable to rotate through a reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.The mica raw mineral material is crushed into small particles by a hammer crusher and then sent to the storage bin by a hoist. After passing through a vibrating feeder and an inclined feed pipe, the mica particles are evenly sent to the upper part of the turntable's bulk tray. Mica particles scatter around the circumference under the action of centrifugal force and fall into the raceway of the grinding ring, where they are impacted, rolled, and ground by the ring rollers. After being processed into mica powder through three layers of raceway, the high-pressure fan draws in external air through suction and brings the crushed mica powder into the powder selection machine. The rotating impeller inside the powder selector causes the coarse mica powder to fall back and grind again, while the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged through the discharge valve at the bottom, which is the final micaSuperfine powderThe airflow with a small amount of fine dust is purified by a pulse dust collector and discharged through a fan and muffler.
muscovitepulverizerPerformance characteristics:
●**
When the fineness of mica powder and the power of the motor are the same, micaUltrafine grinding machineMore than twice the output of air flow mills, agitation mills, and ball mills;
●Long service life of vulnerable parts
muscovitepulverizerThe grinding rollers and rings are forged from special materials, greatly improving their durability. When the fineness of mica raw ore and finished product is the same, micaUltrafine grinding machineThe service life of vulnerable parts is 2-3 times longer than that of impact crushers and turbine crushers, generally up to one year or more; suchpulverizerWhen processing calcium carbonate and calcite, the service life can reach 2-5 years;
●High safety and reliability
followpulverizerThere are no rolling bearings or screws in the grinding chamber, so there is no problem of vulnerable bearings and seals, or damage to the machine due to loose screws;
●High product fineness
Through thispulverizerThe fineness of the processed mica powder can reach D97 ≤ 5 μ m in one go;
●Low environmental pollution
Grinding machineThe use of environmentally friendly pulse dust collectors and mufflers in the equipment greatly reduces dust and noise pollution to the surrounding environment.
