Firstly, the wet coal powder are fed into the crusher to be crushed in order not to affect the drying effects inside the dryer. The crushed materials will be sent to the drying drum where there are many plates. The spiral materials drives the constant movement of barrel and are crushed again by the supporting wall. Thus there are full contact between the raised materials and the hot air. At last, the finished materials will be discharged from the discharging port.
The comprehensive utilization of coal powder has become one significant technological and economical policy in China economic construction. It is also the important means to solve the contradiction between the environment pollution and resource scarcity. The
gypsum processing produced by us has been produced in many provinces and won the favors from customers.
The new type coal powder drying machine produced by us is made up of three parts, namely, heating system, heat-exchange system and dust removal system. Environment protection and wastes circulation have become the important problems in the production process in each industry. With the development of high electricity consuming industries in China, the demand for electricity energy increases annually. Accordingly, the total emissions produced by thermal power plant increases annually.
The heating system of this machine adopts the hot blast stove technology with the features such as sufficient heating power, fine heat transferring effects and simple structure. The heating system has high heating exchanging efficiency because the raised plates inside the barrel is spiral and the materials can be processed again and again. Dust removal system is the key system in the whole processing systems. Because the coal powder is fine in granularity and light in weight, therefore, the dried powder is easy to be taken away by the air flow.
