Product Description

Ultra-fine grinding machine (also known as calcite micro-grinding, limestone micro-grinding, micro-powder mill, marble micro-powder mill, feldspar micro-powder mill, Fluorite micro-powder mill is mainly suitable for 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, carbon black, kaolin, bentonite, Talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alum, graphite, fluorite, phosphate rock, More than 100 kinds of materials such as potassium ore and pumice, the fine powder finished product can be adjusted freely between 325-3000 mesh.
Mill production line usually has hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-grinding main machine, frequency classifier, double cyclone dust collector, pulse dust removal system, high pressure fan, air compressor , electrical control system and other components. The bulk material is crushed by a hammer crusher into a feed size (about 1 cm) suitable for the operation of the ultra-fine mill, and then the fineness of the analyzer is adjusted by adjusting the rotation speed of the analyzer to be suitable for the production requirements. It is also possible to configure automatic micro-powder balers and different types of mills as needed.



The working principle of the ultra-fine mill:

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.

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 discharged through a fan and a muffler.
