Factors affecting the slag vertical mill production quality

Usually in industrial production will discharge some abandoned slag. In the past they are always not rational use, not only pollute the environment, but also caused a lot of waste of resources. With the development of industrial technology, these problems have been resolved gradually, slag is grinded by vertical mill and applied to concrete, cement to improve their overall performance. By this way not only protect the environment, but also improve the utilization of resources, bring great economic and social benefits.

As more and more slag ore appears in the market, the competition is become more and more intense.So what is the main factors that impact the production quality of vertical slag mill yield ? How to improve the slag vertical mill production quality?

The factors influenced the quality are quite many, the most important ones are as below:

First, the influence of the material

Stability of feeding the amount is the key of vertical mill normal operation, Feeding unstable will cause feed material bed wear, even severe uneven stove when coking production.The iron content of the material also affects the yield and quality of vertical mill, the material contains coarse particles of iron or material conveyor belt has chunks of other impurities, it may even result in a stuck impeller feeder, therefore, require homogeneous material level of stability and as much 

Second, the impact mill operating pressure

The mill operating pressure will directly affect the yield and quality of vertical mill.If the operating pressure increased, their grinding capacity also will increase.Therefore,base on ensuring the quality of the vertical mill capacity mill operating pressure can not be set too high, it should be ready to adjust the operating pressure of the actual situation.

Pressure on the ratio of the reference

Grinding clinker: 8.0 ~ 9.0MPa

Grinding slag: 9.0 ~ 9.5MPa

Third, the influence of the classifier 

classifier powder selection ability directly affects the quality of the grinding. The higher the efficiency ,less qualified fine powder go back grinding, finished product output is higher, the opposite is low.Therefore, choose a kind of powder with high efficiency of vertical mill equipment.

Classifier speed reference 

grinding clinker: 105 ~ 120 r/min 

grinding slag: 130 ~ 145 r/min

Forth, the influence of air flow 

in general, the size of the mill air volume is one of most important factors affecting yield.Insufficient air volume will form the ability of dust, and the air volume is too big and will increase the load of dust collector, this will affect the quality of vertical mill production.Therefore, different ground conditions, different production, different requirements have different air volume control results.

Fifth, the quality of the vertical grinding machine itself

 the quality of slag vertical roller mill itself is also one of the most important factor.Therefore, choose a good slag vertical mill equipment is very important.Xinxiang Great Wall machinery since established in 1958, focused on vertical grinding machine for more than 50 years.GRMS slag vertical grinding machine is the Great Wall machinery in response to the national energy conservation and emission reduction policy, scientific research team after more than 10 years research and develop this significant energy saving, environmental protection, low carbon product machine.This machine was deeply loved by the masses of customers at home and abroad, this advantage is closely linked with grinding machine itself.The following is the unique advantages of Great Wall mechanical slag vertical mill:

1, Vertical slag mill production line system power consumption is 43 KWH/t commonly, energy-saving effect is remarkable

2, unit coal consumption quantity is little, reduce the cost

3, slag vertical mill machine equipment stable performance, operation rate is above 95%

4, widely used, can grinding a variety of materials

5, little noise, dust concentration is low, environmental effect is remarkable

6, customer purchasing many cases, all over the country
