1. The configuration of ball mill is very expensive.

Owing to the rotating speed of ball mill barrel is low about 15-25 r/m, it needs expensive reduction gear if collocating with common electric motor.

2. The production cost is high.

The grinding body itself will suffer abrasion when impacting and grinding materials, and the spare parts such as scaleboard will suffer abrasion as well. Therefore, during the whole production of cement, the consumption of iron plate quantity of the grinding operation is a large amount. According to analysis, it consumes about 1 kilogram of iron to produce 1 ton of cement.

3. The working efficiency is low.

For example, in the process of producing cement, the electric quantity used for grinding operation accounts for about two thirds of the whole factory. According to statistics, the electricity consumption of producing 1 ton of cement is not lower than 70 kilowatt hour. However, the electricity can't be utilized effectively. 4. The body form. is too heavy and cumbersome.

The total weight of large ball mill can reach to more than hundreds of tons so that the one-time investment is too high. The future one year will be an important year that the ball mill equipment industry develops with stronger growth speed, especially for those ball mill manufacturers in domestic market. There is no doubt that there will be precious development opportunities. Companies should improve themselves and accelerate to innovate their products and build an overall after-sales service system.

These are only some of the problems that ball mill faces in current development and if ball mill manufacturers can overcome these problems, ball mill will have better development opportunities.
