High Strength Grinding Mill

The high strength grinding mill produced by Fote Machinery is suitable for grinding barite, slag, limestone, ceramic and other non-inflammable and explosive materials that Mohs hardness is not greater than 9.3 grade

Details of this product

The high strength grinding mill produced by Fote Machinery is suitable for grinding barite, slag, limestone, ceramic and other non-inflammable and explosive materials that Mohs hardness is not greater than 9.3 grade and humidity is below 6% of in mining, metallurgy, chemical industry and building materials industry. The granularity of finished products are adjusted in the range of 80- 425, and the smallest is 1000 Mesh.

  • 1. Three-dimensional structure, small footprint, in complete set and independent system from lump material to finished powder
  • 2. Even fineness of finished powder. screening rate is 99%
  • 3. Important parts adopt high-quality steel materials and wear-resistant parts all use high-performance wear-resistant materials. The wear-resistance of the high strength grinding mill is high and works reliably.
  • 4. The electrical system of Fote high strength grinding mill adopts centralized control. The grinding workshop basically can realize unmanned operation.

Limestone Grinding Mill

Limestone grinding mill is also called limestone mill, which is a kind of Raymond mill, and which is widely used in grinding and processing processes of mineral materials in metallurgy, building material, chemical, mining and other fields.Limestone grinding mill is also called limestone mill, which is a kind of Raymond mill, and which is widely used in grinding and processing processes of mineral materials in metallurgy, building material, chemical, mining and other fields. There are various kinds of inflammable and explosive mineral materials that can be ground by barite grinding mill, such as quartz, feldspar, clay, talc, calcite, clay, barite, fluorite, gypsum and clay whose humidity is below 6%.

  • 1. Compared with other gypsum grinding mill or calcium carbonate grinding mill, the grinding pressure of grinding roller to materials has increased 800 to 1200 kg under the impact of ultra-fine spring.
  • 2. Energy saving. Under the situation of same yield and fineness, energy consumption of Fote gypsum grinding mill and calcium carbonate grinding mill is only one-third of other barite grinding mill.
  • 3. Low investment and high efficiency, under the situation of same yield and fineness, the price of Fote barite grinding mill is only one-fourth of raymond mill.
  • 4. Less production processes. Compared with raymond mill, Fote limestone grinding mill, barite grinding mill, gypsum grinding mill and calcium carbonate grinding mill can reach an average particle size of below 6.5um at a time..
