Fly ash ball mill is a type of ball mill, which can be used to grind waste coal slag discharged from power plants and coal yards. After grinding by the ball mill, fine powder is obtained. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal mineral processing, glass and ceramics and other production industries to dry or wet grind various ores and other grindable materials.

Fly ash materials: Fly ash is a misplaced resource. Fly ash can be used as an admixture for cement, mortar, and concrete, and becomes a component of cement and concrete. Fly ash is used as a raw material to replace clay production. The raw materials of cement clinker can be used in chemical industry, metallurgical mining and other industries after processing.

The long-term operation of the fly ash ball mill may cause high temperatures in the bearings, sliding shoes, etc., which will affect the normal operation of the equipment, causing equipment shutdown, damage and other failures. In addition, it will also cause the temperature of the grinding cement to rise too high. So what are these situations? What about the hazards? The editor of Yingkuang Machinery made some summary based on the daily processing of 80 tons of fly ash ball mill:

1. Excessively high temperature of the cement after grinding will directly affect the construction quality of the cement clinker, causing temperature difference stress in the cement concrete and causing the dangerous phenomenon of concrete cracking;

2. Excessively high temperature rise during the operation of the mill will cause damage to the machine parts and thermal deformation. If the main bearing heats up too high, it will cause difficulty in its care and accelerate damage;

3. High temperature inside the mill will cause thermal stress in the cylinder, causing the lining screws to break, which can easily cause equipment failure and affect the normal operation of the equipment;

4. Excessive temperature rise will also cause the cement to ball up, resulting in reduced grinding efficiency, reduced production capacity, and inability to complete the work on schedule;

5. It will increase the circulation load rate of the grinding system, reduce the output of the mill, and also affect production.

So what should we do if the temperature of the ball mill with a daily processing capacity of 80 tons of fly ash is too high? How can we reasonably control the temperature rise problem? XKJ GROUP will give you advice and answers.

1. Use a cement cooler, which can reduce the cement temperature from 110℃ to 65℃, which is better;

2. Strengthen the management of feeding materials, feed materials with too high temperature into the mill, and lower the temperature;

3. Use grinding aids. The use of grinding aids can not only increase the output of the grinding mill, but also help reduce the temperature of the grinding cement;

4. Pay attention to the ventilation of the mill, and effective ventilation can better reduce the temperature of the grinding material;

5. Use the spray inside the mill to cool down. This measure has immediate results, effectively controls the temperature of the cement leaving the mill, and increases the output by about 8%-10%.

The fly ash ball mill is composed of feeding, supporting, discharging, transmission and other devices. It has good adaptability to materials and can be produced continuously. It has the characteristics of large crushing ratio, reliable quality, high production, energy saving, high production and environmental protection.
