Cement grinding mill is the key crushing equipment that the material is crushed, and then be grinded. Cement grinding mill can grind a variety of ore and other abrasive materials by dry or wet grinding. Cement grinding mill can be used in many cement production lines, because it has a great advantage in cement grinding. Cement grinding mill has the features of strong adaptability to the material, continuous production, crushing ratio, easy to adjust the fineness of grinding products. Cement grinding mills can be produced both dry and wet, and can also be in operations of grinding and drying at the same time. Users are looking for a higher capacity of cement grinding mill in the use of cement mill, thereby reducing the production costs. This article gives you a few tips to increase the capacity of cement grinding mill.
First, the changes of grinding grain size
In general, energy consumption of the early crushing is lower than the latter part of the cement grinding mill, and investment costs be lower. At the same time, the smaller is the particle size of the martials into the mill, the higher is grinding efficiency of cement grinding mill. Therefore, comprehensive consideration, you can increase the fine crushing equipment before the process of the cement grinding mill, which makes the grinding grain size greatly reduced, thereby reducing the grinding system load, improving the election efficiency of the powder, then the most direct benefit is the finished powder to be elected in a timely manner to reduce the back rate of cement finished powder, and reduce mill load.
Second, the improvement of grinding process
For increasing the capacity of cement grinding mill, it is the most fundamental that to improve the grinding process. There are two grinding processes: open grinding system and closed grinding system. Under the same conditions, capacity of the closed grinding system is about 20-35% higher than the open grinding system. The production of closed grinding system, and its particle distribution is relatively uniform, and it is also more convenient to adjust the level of cement. On the contrary, the grinding material of open grinding system is the finished production, and its particle distribution is more dispersed, there is over grinding phenomenon, affecting the quality and production of cement a. Therefore, we generally recommend the closed grinding process.
Third, the reasonable gradation of the steel ball
The working of cement grinding mill is mainly depends on the impact of the steel ball to the material and making the material grinded when the rotation of the cylinder, whether the gradation of steel ball is reasonable or not directly affects the capacity of cement grinding mill. According to production experience, the determination of the steel ball grading to meet the following principles. According to the size, hardness, abrasion resistance of the material into the grinding mill, and the fineness of the product requirements to determine the ball grading. It is a certain relationship that selecting the size of the ball diameter, and mill volume of material per unit. It is mill liner surface shape that one of aspects to be considered that the gradation of the steel ball.
Fourth, the control of ventilation quantity
It is critical that the internal ventilation of cement grinding mill, which has a significant impact on the production and quality of cement grinding mill. The role of ventilation is on the one hand, the fine powder will be discharged within the mill, so as not to affect the grinding efficiency; on the other hand, to reduce the temperature inside the mill, avoiding the excessive temperature of the internal mill.
