When the ignition, rotary kilns occur blasting because of low temperature, the reason is a low ignition temperature in the kiln, with coal combustion is bad, when the coal falls to a certain extent ,burning fierce,causing local concentration of heat, blasting phenomenon occurs. Prevention method is to maximize improve the ignition temperature, reducing coal consumption, shorten the ignition time. The rotary kiln in the application area, the numbers to be most cement industry. The whole process ofcement production line summarized as "two ground a burn," with "a burning," is made by grinding good raw material, in the high temperature of kiln under the action of the process of burning become clinker. The equipment is also widely used in metallurgical, chemical, building, refractory material, environmental protection, and other industries.
Our companyis a large industrial machinery manufacturers in China.which is focus on mining machinery, complete sets of processing equipment, building materials equipment of rotary kiln,and coal gasifier,ball mill,dryer, etc. The rotary kiln under high temperature overloaded alternating slow operation, and its annex equipment maintenance and thermal rail system related to the level of control of the rotary kiln working safety and efficiency. Therefore, rotary kiln cement produces the host, commonly known as the cement factory "heart". The ways of heat transfer in the rotary kiln can be divided into three types: the diversion, the convection and thermal radiation. It calcines the materials by the three ways. The next, let us know about the three ways of heat transfer.
At the present, Hongxing mining machinery has set up three
