Basalt is an aphanitic (fine-grained) igneous rock with generally 45-53% silica (SiO2) and less than 10% feldspathoid by volume, and where at least 65% of the rock is feldspar in the form of plagioclase. Basalt commonly features a very fine-grained or glassy matrix interspersed with visible mineral grains. The average density is 3.0 g/cm3. Basalt is usually grey to black in colour.
The use of basalt is very extensive. Its application is not limited to the construction industry. For example, basalt is a good raw material for the production of “cast stone”. After melting and casting, crystallization, annealing and other processes, it can form a hard and wear-resistant alloy steel. A new type of material that resists corrosion of lead and rubber; basalt can also act as a “lubricant” in the advanced technology of a cast steel, and can cast the life of the cast film; and basalt can also be drawn into glass, made of Basalt glass fiber cloth is more resistant to alkali than general glass fiber cloth and has good high temperature resistance.
Guilin hengda mining machinery Co., Ltd is a professional raymond mill manufacturer. For Basalt grinding, HD1720 raymond mill is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, the accuracy is 80-600 meshes. The classify efficiency reached 99%. HD1720 has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
HD1720 raymond mill specifications:
Max feeding size: ≤30mm
Main motor power：220kw
Final product size: 80-400 mesh
Applications : For non-metallic minerals with a Mohs hardness of 6 or less and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, , zircon sand, bentonite and other non-metallic minerals.
Don’t hesitate to get a factory price of HD1720.
