Diatomaceous earth contains a small amount of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 and organic matter. SiO2 generally accounts for more than 80%, up to 94%. The iron oxide content of high-quality diatomite is generally 1~1.5%, and the alumina content is 3~6%. The mineral composition of diatomite is mainly opal and its variants, followed by clay minerals – hydromica, kaolinite and mineral debris. Mineral debris includes quartz, feldspar, biotite and organic matter. The content of organic matter ranges from trace to more than 30%. The color of diatomite is white, off-white, gray and light taupe, etc. It has the properties of fineness, looseness, light weight, porous, water absorption and strong permeability.
Features Of DMC 1. The separation efficiency of the heavy medium cyclone is relatively higher than that of the ordinary hydrocyclone, which is also one of the important factors that people like to use it. 2. The adjustment range of the separation density of the heavy medium cyclone is relatively wide: the separation density of the heavy medium coal separation is generally 1300 kg/m3 ~ 2200 kg/m3 and it is also convenient to adjust this is its advantage. 3. The heavy-medium cyclone has a relatively strong use capacity and not only has a wide range of sorting strength, but also has a good effect on the quantity and quality of coal preparation. 4. The sorting particle size range is wide. The size limit of the lump coal separator is generally 100-6mm, and the particle size limit of the fine coal heavy medium cyclone is 50-0mm (the sorting depth can reach 0.15mm). 5. The heavy medium cyclone has large processing capacity, the current maximum processing capacity of the heavy medium separat
