Need Prevent the Explosion Hazard of Cement Production Line

Cement is a kind of hydraulic cementing material. When cement is mixed with water, after a series of physical and chemical reactions, cement will change from plastic pulp into hard rock. Cement production line or cement plant is a series of cement making machines for manufacturing cement. It is mainly composed of such processes as breaking and prehomogenization, preparation of raw material, preheating decomposition, the firing of cement clinker and cement grinding packaging. Cement plant includes cement rotary kiln, cyclone preheater and comb cooler.

In coal grinding project of cement making production line, it usually uses the ball mill, 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.

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.

Cement Production Line' />


1. sealing system for cementrotary kiln equipment. 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.

2. 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.

3. reduce coal accumulation.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.
