If the control of vertical ball mill and ball mill is not improper in industrial and mineral production line, excessive discharge will appear. And the ball mill is easy to stop working because of excessive discharge. Here we would like to provide some method of skills to solve the downtime caused by excessive discharge.

1. We should adjust the system air volume to l70000m3 / h and the roller pressure to l0MPa.
2. There are 9 steel plates with 200mm × l00mm × 5mm in the welding, three in the back of each roller. This method is to reduce the wind area and increase the wind speed.
3. We should increase the pressure when the weight of material is about 2t.If it is fluent to lift the roller, we should reduce or stop the feeding timely. Thus we can avoid the current rise of bucket elevator caused by too many recyclable materials.
The development of construction machinery industry is becoming more and stronger. The growth rate of infrastructure and real estate investment will continue to accelerate in the second half year, which will have great hope to drive the growth in machinery industry market. Moreover, with the slow recovery of economy, the export of engineering machinery industry environment will be further improved.
Under the guidance of government investment policy, the demand for construction machinery will enhance obviously. The trend of construction machinery is gradually warming up. The quick speed of real estate investment will accelerate the demand for construction machinery. Analysts said that the three areas: real estate, mining and infrastructure could contribute to the development of mining equipment.
Main export area of China's construction machinery products are Asia, Africa and Europe. And from the distribution in the map, the countries with rich petroleum, mineral are major exporters of construction machinery in China. The price of crude oil, non-ferrous metals and other commodity rebounded sharply in the first half year in 2009.With the global economy stabilized gradually, the demand of mining, energy and metallurgy will be gradually restored. And the confidence of investment is recovering.If the control of vertical ball mill and ball mill is not improper in industrial and mineral production line, excessive discharge will appear.
