Brief Introduction
What is HGM Ultrafine Mill?
Adopting advanced German technology and coupled with our engineers' experience, Fote developed a new type grinding machine, HGM ultrafine mill, from Raymond mill. Fote HGM ultrafine grinding mill has a large production capacity, wide application and reliable performance. This series of grinder can process over 200 kinds of materials under 7-degree Mohs hardness. Generally, HGM ultrafine mill is also called HGM ultrafine grinding mill or HGM ultrafine mill grinder.
Applications
As a kind of Raymond mill, HGM ultrafine mill grinder finds a wide application for powder making in metallurgy, building materials, chemical industry and mining industry, such as silica/quartz, feldspar, talc, bauxite, slag, activated carbon, dolomite, yellow iron oxide, kaolin, coke, clay, bentonite, basalt, gypsum, graphite and other inflammable materials with under 7-degree Mohs hardness and below 6% humidity.
Working Principle
Large-sized materials are crushed into smaller pieces and lifted up to hopper by the bucket elevator, then fed into the body. Gears drive rollers and the central axis roll at a high speed on their own axis. Meanwhile, the rollers rotate around the central axis. With the effect of centrifugal force, small-sized materials are bladed up and ground by the rollers which are pressing on the rings toughly. Those qualified powder will be gathered and blown out of the machine. Those do not comply with the requirement will be back to the roller and be ground one more time. The extra air generated during the process will be purified by the bag dust collector and then blenched out.
Advantages
HGM ultrafine mill is mainly composed of the body, analyzer, fan, micro-powder cyclone separator, product cyclone separator, wind pipe, etc. Compared with Raymond Mill, HGM ultrafine mill has the following advantages:
- Large application. Modular design of the powder concentrator allows an adjustable fineness of different materials;
- Fine powder diversity control. The powder concentrator has a function of variable frequency, which gives a control on the ground materials;
- Easy and convenient maintenance. Advanced sealing technology assures a long period of refueling maintenance, which is low-cost;
- Automatic dust removal. Pulse dust removal is adopted to realize an automatic operation. It is a technical process of manpower-saving.
- High production and efficiency. HGM ultrafine grinding mill uses spring booster, increasing the grinding force.
