Raw Material Preparation Rolling Machine Final Grinding Is The Direction Of Development

Cement industry as a traditional energy consumption, energy consumption along with the entire process of cement production, grinding process is the electric tiger, cement production power consumption is mainly used in grinding. The energy consumption of the grinding process is mainly reflected in the preparation of raw material, pulverized coal preparation and cement grinding, and the raw material powder consumption accounts for about one quarter of the cement power consumption. In recent years, Grinding for grinding raw materials, and further reduce the grinding power consumption.

Industry chief engineer Jia Huaping interview with China Cement Network, said the Rolling Machine for the final preparation of raw materials, not only significant energy-saving effect, and operation and maintenance are easier, spare parts costs are much lower, should be The future of a development direction.

In terms of grinding system, the specific surface area of raw materials is generally about 200m2 / kg, at this stage simply can not talk about grinding, affecting the quality of production is mainly fragile; affected by the stage of grinding, Surface area is generally more than 320m2 / kg, which is cement. Therefore, the concern about the raw material should be fragile, rather than abrasive, Rolling Machine for raw material grinding is more suitable for cement grinding.

In view of the raw material Rolling Machine the final grinding system has significant energy-saving benefits, and follow-up maintenance and repair is simple, low operating costs, Jia Hua-ping on some of the company's Rolling Machine raw material grinding use was investigated. From the current company's rolling machine raw material grinding use of the situation, the overall energy-saving effect is worthy of recognition, there are some enterprises in use there are some problems.

The problem occurs in the stick on the Rolling Machine, the study found that the Rolling Machine system is not afraid of the end of the rain, but also not afraid of soil and more, fear of both are more, resulting in Rolling Machine sticky block.

Therefore, Jia Hua-ping suggested that enterprises in the choice of Rolling Machine raw material grinding system, we must carefully consider the Rolling Machine sticker blocking the problem, the appropriate increase in rain inventory, strengthen the system insulation measures to strengthen the system drying capacity, or even The drying system is introduced into the drying system to ensure proper production at the same time as power saving. For the rain and more raw materials and more production conditions, it is best not to use!

From the "ground mill domestic - grinding without ball - Rolling Machine raw material grinding - cement grinding multi-level sorting - to enhance the system to maximize energy conservation," China's cement network has been to focus on and promote the cement industry grinding system The development and progress as their duty, let us look forward to the cement grinding system of new technology, new technology, the birth of new equipment.
