Cement Production Line

Devices Involved In Cement Production Line

In the cement production line, we need not only the crushing machinery, but also the grinding machine. The whole production process of cement is generally as follows: homogenizing-- preparation of raw material -- raw material homogenization -- preheat decomposition -- the burning of cement clinker -- cement grinding mill -- cement packaging. In the process flow, different cement making machines should be used.

Generally speaking, the cement production concludes a complete set of cement machinery. And in Hongxing different capacities can meet your demand.

Constitution And Process In Cement Production Line

Cement manufacturing consists of raw material grinding, blending, pre-calcining, clinker burning and cement grinding. In short, limestone and other materials containing calcium, silicon, aluminum and iron oxides are crushed and milled into a raw meal. This raw meal is blended and then heated in the pre-heating system (cyclones) to start the dissociation of calcium carbonate to oxide. The material goes further into the kiln for heating and reaction between calcium oxide and other elements to form calcium silicates and aluminates at a temperature up to 1450 cent degree. The cyclone system is attached to the rotary kiln by a riser duct. Secondary fuel is fed to the riser duct, and the main fuel mixture, coal/petcock, fires the kiln. Reaction products leave the kiln as a nodular material called clinker. The clinker will be interground with gypsum and other materials to cement.

Some Ways To Increase The Cement Making Plant Efficiency

1. To enhance the ventilation of mill is the effective method to increase the production capacity and to reduce the power consumption.

2. To adopt the new type scale board to improve the material of the mill parts. The new type spare parts with easy grindability are widely used nowadays for prolonging the service life of parts and grinding media.

3. To add grinding aid to increase the grinding efficiency: there are many kinds of grinding aids, most of which are organic surface-active materials. Some research has shown the grinding aid of ethanol, butanol, butanol oil, and coalmine works out fine.

4. To reduce the temperature of cement to improve the quality; high temperature will cause the dehydrate gypsum dewatering in cement processing, which will make cement false setting and material cementation.
