Cement rotary kiln is one essential machine in the cement production process, which also is the heart of the cement production line. Cement rotary kiln can be briefly called cement kiln or circumgyrate cement kiln, which is mainly used for the cement raw material burning. In the cement making procedure, the cement raw material is calcined, mixed and smashed to clinker in the cement rotary kiln. Then the clinker will be grinded and then mixed with some batching to make into cement. So, the key point for controlling the quality of cement should happened on cement rotary kiln. But almost every producer may face the problem that the ring formation and leakage of material may happen to cement rotary kiln. Here Henan Hongxing Mining Machinery Co., Ltd. will give out an analysis of ring formation and leakage for cement rotary kiln.


The main reasons that may cause the rotary kiln ring formation consist: when the contain of sio2 in the ore mesh is higher than Fe2O3, low melting point silicate will be produced, that is so called ring formation; Too high water contain in the coal ash may cause the ring formation because of the incomplete combustion; The incorrect operation caused the temperature of rotary kiln a little high; Check and repair the rotary kiln before cooled down.

Solving measures for the ring formation of rotary kiln: The most easy method to deal with the ring formation is all by artificial. The workers should clean that with instrument in particular time. The ring formation can also be cleaned by calcined, when processed in alternating cool and hot, the ring formation may fall down automatically. When the ring formation of the circumgyrate cement kiln is solved,the sealing problem is obviously solved.If the sealing of the kiln is guaranteed, the leakage of material is also solved at the same time.

Increase the ore ash grade to reduce the sio2 contain in the material; Never feed the material to the rotary kiln until the coal ash is dried; Control the temperature of the rotary kiln strictly and set up the procedure of record and check for the temperature; Check and repair the rotary kiln when it is cooled down.
