Coal Slime Washing and Drying Equipment different treatments for different drying technologies

The coal produced by different coal types and slime recovery processes will be different in terms of quality and water holding capacity. For example, the flotation tail coal of the coking plant and the coal produced by the thermal coal will differ in both physical quality and physical properties. Therefore, the Coal Slime Dryer manufacturers will also have differences in technical processing.

According to the different sludge recycling process, the physical properties of the slime vary greatly. If the slime recovered by the filter press has a relatively uniform particle distribution, its viscosity and water holding capacity are relatively weak, which is beneficial to reduce moisture. The other is a slime sedimentation tank or a tailings mine. According to the principle of solid precipitation of solid particles in water, the coal slurry produced by solid-liquid separation is realized. This process has the function of particle size classification, the coarse particles are easy to precipitate, and most of them are concentrated near the inlet of the slime water, the fine particles are in the middle position, and the extremely fine particles are at the end. The end slime has high viscosity and high water holding capacity, and the drying method can not achieve the expected drying effect.

Similarly, in the centralized treatment of coal washing and drying special machines, there will be certain differences in technical processing such as drying strength. However, the use of tumble dryer for mechanized drying is undoubtedly more active in terms of drying efficiency, drying quality, daily processing amount of coal slime, and solution to slime pollution, and the dried slime can be better used. Blending or direct incineration is more in line with the industrial production of large coal enterprises.

Dingli Brand Coal Slime Rotary Dryer is dried at high temperature, and can achieve dryness and upgrading of several hundred tons or even thousands of tons of processing time per unit time. The dry coal slurry has low water content, can be controlled below 5%, and the dry material particles are uniform. Dry and wet evenly, at the same time, the drying process is clean and environmentally friendly, which is an important mechanical equipment to realize and improve the economic value of coal slime.
