It Is Important to Clean the Rotary Kiln Ash

Rotary kilns are used to heat solids to the point where a required chemical reaction(s) takes place. The revolving kiln is basically a rotating inclined cylinder. Solids retention time in the kiln is an important design factor and is set by proper selection of the diameter, length, speed, slope and internals design. There are two basic types of rotary kilns; direct fired and indirect fired.

When horizontal kiln is applied in chemical industry,it can be used in the production of sodium bicarbonate, calcining phosphate fertilizer and barium sulphide etc. When rotary kiln is adopts in metallurgical industry, it can be used in the production of aluminium hydroxide. Rotary kiln is suitable for processing solid granularity and gas medium in chemical or physical process, the gradient of clinker rotary kiln is between 3.5% and 6%, Rotary kiln has good calcining quality and stable production capacity.

Henan Hongxing Mining Machinery Co., Ltd. takes the kiln ash mixing way, distribution and volume into consideration. Because of the unstable kiln ash has close relationship with fluctuation of raw materials batching. Not only the theory, but also the practice, it is proved that is the ideal method to removal kiln ash effect on raw materials batching. Generally speaking, rotary kiln ash mixture percent should be controlled at about 5%.

Hongxing engineers design the outlet of clinker rotary kiln ash near the cement making machinery, we should put the cement grinding line together with clinker calcination production line. In the technical process of using kiln ash as mixture,accurate batching of kiln ash is the most important thing in the calcination process, which directly effects the cement quality. Therefore, we should control the kiln ash mixture volume and automatic batching bin of rotary kiln ash, guarantee stable feeding and make the kiln ash using temperature not too high.
