To grinding head, grinding end of rotary kiln, pulverized coal classifier, dust collector, warehouse, equipment such as pipeline set lock closure device, prevent oxygen into the system. Secondly, reduce coal accumulation. When grinding fineness in cement production line of pulverized coal under 80 um, job shop in the amount of coal particles suspended in the reaches a certain level, the higher the content of oxygen in the air when the more prone to explode. So the following is five good suggestions to give the prevention method of coal dust explosion hazard. Firstly, sealing system for cementrotary kiln equipment.

At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of cement plant，cement grinding plant and free service for assembling various kinds of cement making production line. A series of coal dust explosion hazard happened in the Kunshan matter in Aug.2nd, which caused the attention of local government. In coal grinding project of cement production line , which usually uses the ball mills, flour mill equipment grinding coal powder into fine powder particles, fine pulverized coal through coal injection pipe is sprayed into the cement rotary kiln to burn adequately.

Pulverized coal accumulation within the system easy to check out of the rotary kiln, such as pipe, valve, coal conveying duct and classifier, dust collector, etc. Thirdly, control the concentration of combustible gas. In the pulverized coal bunker set concentration of combustible gas alarm device, reach the standard concentration exhauster to warehouse must be used in gas concentration are out of control.

Our effective rock crushing machine could be applied to series of construction companies. For instance, the cement factories and building companies would need to use it to accomplish completed tasks. It enable the customers to earn more profits since the energy consumption is reduced. During the researching and manufacturing, Fote Machinery believe that we should connect our designs with the cement Plant market demand.
