The technical prospect of cement production process

As we all know, the cement industry is typical large energy consumption industry, energy consumption along with the whole cement production process, grinding process is the electric tiger which contains most of the consumption in cement production grinding. Under the fierce market competition and pressing energy-saving pressure, energy-saving measures continue to be introduced. Whether there is a significant energy-saving process?11

1. The raw materials separation grinding

In fact, there are many manufacturers encounter the problem of large difference between the grinding ingredients. Such as siliceous materials, especially the use of rigid sandstone ingredients business, sandstone and limestone have a large difference in the abrasive. More importantly, larger sandstone particles form bottlenecks that constrain solid-phase reactions. We all know that the cement clinker minerals are completed by solid-phase reaction, the more finer raw material grinding, the smaller the particles of the material, the greater the surface area, the greater the contact area between the components, the greater the surface of the free energy, make the proliferation and response capacity increased and the response speed up.

But in the actual production, the finer raw material grinding, more power consumption will be. How do we minimize the coarse particles size of raw material and at the same time reduce the power consumption? It is necessary to control the fineness of raw materials in a narrow range; how do we grinding sandstone while not to process other components too finer for those large abrasive ingredients. Then to separately grinding sandstone and other components is completely necessary.
