Analyze One Special Application of Rotary Dryer

Drying is the fundamental thermal process in cement process. The drying degree affects the cement property directly so drying equipments must be paid enough attention. Drying can proceed with crushing and powder selection. Now cement plant most adopts drying-grinding system. This method can simplify the technology steps, decrease heat consumption, but if the water content exceeds the limit, it needs another dryer to be prebaked.

Cement plant adopts dryer such as rotary type, suspension type, flow regime type, boiling type and gravity type. The most common is rotary dryer. Although it is low efficiency, large investment, it is well-adapted can dry all kinds of materials, and it is operated easily and reliably. Rotary dryer produced by Henan Fote Heavy Machinery Co., Ltd. has many advantages like reasonable structure, perfect manufacturing, high yield, convenient operation, big radiating surface, low energy consumption and large heat exchange area etc. It is mainly composed of revolved body, lifting board, transmission device, supporting device and sealing ring, etc.




Water content of entering the grinder influences the output of grinder, material quality out of the grinder and grinder operation. If the material has much water, high humidity in grinder, fine material will adhere to the grinding body, scaleboard and partition decreasing the grinding efficiency, and it will worsen the grinder operation conditions and increases difficulties to operation and quality control. In addition, material fed into the grinder, its mix proportion will change influenced by water fluctuation of material, so the product quality will be affected. Therefore, eliminating excessive water is the necessary step of cement production.

As a professional drying equipment manufacturer, Henan Fote Heavy Machinery Co., Ltd. produces various dryer machine, such as desulfurization gypsum drying machine, clay drying machine, steel slag dryer, wood chip dryer, clay drying machine, etc. Welcome to visit and purchase: info@sinoftm.com.
