Technical pathway to improve energy-saving ball mill
The high efficiency of the cement grinding process, low energy operation, has always been the goal of the pursuit of production enterprises. \"Raise the production of ball mills\" is also an eternal topic. For more than a decade, there have been a lot of research, vertical grinding, extruded grinding, etc., etc., etc., so that this process is greatly accelerated. However, from my country's national conditions, cement production is still dominated by small and medium-sized scale, and the grinding equipment is also dominated by a relatively simple structure, operation and maintenance management, and cannot be fundamentally changed in a short period of time. Therefore, raising the grinding efficiency of the ball mill, the maximum increase in fine, high-yield and low energy consumption, still a long-term work. In particular, the kiln cement enterprises have made higher demands with the improvement of cement, and the specific surface area and particle composition of the cement, the specific surface area and particle composition of the cement, and the composition of the cement, and the composition of the cement. It is now proposed to \"improve the production of mill production\" and have more important practical significance.
The increase in production during the clinker is increased to the amount of raw materials
In recent years, many g kiln cement companies have adopted new ingredients, into the kiln materials. Increased pass rate, application of small material ball calcination technology, using energy-saving supporting refractory materials, selecting new unloading 子, etc., the output is significantly improved during the clutter. The original supporting raw row machine has begun to appear inadequate production capacity, and some companies have \"currently grinding\". This not only limits the increase in production during the rooking table, but also due to insufficient raw storage, it cannot be used, which seriously affects the stability of the heated kiln thermal system, which leads to a decrease in the quality of the clinker.
1. Cement new standards Implementation requirement to improve cement grinding
After the new standard of cement, cement enterprises often increase the strength of the cement to reduce mixed materials or increase cement specific surface area. The simplest way to achieve higher specific surface area is to reduce the yield of the mill and increase the grinding time, but the result is \"fluorine-grinding phenomenon\", which makes \u003c3 μm of the fine powder increases, and the particle composition is not good, intensity There is not much increase, while the grinding power consumption is greatly increased. This method of improving cement finishing or increasing clinical content is necessary to increase the rise in production costs.
1. Improve the production of mill production is an effective means of reducing the integrated consumption of cement
Survivar grinding and cement powder grinding is two important links in cement production. Each of the production of 2.7 tons of mortar is required for a ton of cement, which is used for the grinding of the grinding operation, which also accounts for more than two-thirds of the integrated consumption of cement. Although the value of cement integrated power consumption has fallen by about 30% compared with the first two or 30 years, it is constantly increasing corrosion efficiency, reducing the grinding power consumption and production costs remains the important goal of our unremitting pursuit.
1. The link between the technological progress of cement enterprises
Many gn kiln cement companies on cement grinding processThe inspection is still not perfect, and the finished product is only measured (fine) the balance of the screwdriver and the specific surface area is not measured.In terms of technical and product quality management, the film emphasizes the \"kiln-centered\" and \"calcination decision everything\", and the investment of technical transformation is often concentrated on the burning system of the bull kiln.The film is considered that as long as the quality of the clinker is good, the cement quality will inevitably be good.Thus there are many plants to produce quality problems in the cement grinding process, but demands from calcination clinkers.In summary, pay attention to the calcination process, neglect the polishing process; pay attention to ingredients, neglect the ball ball, etc., such guiding ideology and management methods are very disadvantageous to the technology advancement of cement enterprises, which should be clarified and reversed.
