The coal briquetting machine is used to press materials with little water content including coal, mineral powder and refractory matter.
The Compound cone crusher(Symons cone crusher) is suitable for crushing materials with medium hardness or above.
High pressure grinding mill has high-pressure springs inside, which can improve the grinding powder to 1.2 times higher. If roller ring is worn out, we can adjust the length of springs to keep the grinding pressure.
Different ores have different magnetic coefficients. Magnetic separator is just the machine that uses magnetic and mechanical power to separate the ores from mixers.
The coal ash dryer made by our company, as the Chinese leading raw coal drying machine supplier, is specialized in drying the coal ash and then makes new use of it.
Cement Mill is one of the important cement making equipment and key equipment for grinding crushed materials, and plays a vital role in the cement manufacturing process.
Spiral chute, also called spiral separator, integrates the advantages of spiral concentrator, shaker and centrifugal separator together.
Mobile crusher is the machine that has crusher, feeder, feeding hopper, belt, driving and controlling systems on mobile chassis.
The coal used in kiln must not have too high an ash content because 220 kg of coal is used to make one tonne of cement. It is worthy when considering the amount of cement. The dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and ...Read More

When concrete is exposed to highly alkaline soil or water having high sulphate content then this type is used. This cement has a low C3A content so as to avoid sulphate attack from outside the concrete. Otherwise the formation of calcium sulphoaluminate and gypsum would cause disruption of conrete due to an increase in volume of resultant ...Read More
