In general, in the processing of limestone by raymond mill, there are three main methods of fineness adjustment, namely the adjustment of the motor speed, the limitation of the grinding roller swing limit position, and the change of the technical parameters of the air delivery system. A detailed analysis of the adjustment methods is mainly as follows:
First, the adjustment of the motor speed
This method is mainly to greatly adjust the spindle speed of the limestone mill, which can change the positive pressure of the grinding roller to the grinding ring, so that the grinding effect changes, and the fineness adjustment will change the output. The motor power of the main unit and the blower can be appropriately increased to increase the output.
Second, limit the maximum position of the grinding roller swing
In the interior of the raymond mill, the grinding roller is one of the important components for grinding limestone. If the maximum position of the grinding roller is limited, a gap is formed between the grinding roller and the grinding ring, and the gap can be adjusted at will, so that the grinding strength and control of particle size can be greatly adjusted, which in turn changes the fineness requirements.
Third, change the technical parameters of the air delivery system
This method is mainly to increase the flow rate of the blower and greatly adjust the wind speed and air volume in the raymond mill. This is more commonly used in the production process of the mill. From the principle of wind selection of the machine, the size of the wind selection and the passing of the wind wheel the flow is proportional.
HD series raymond mill from Guilin Hengda Mining Machinery Co., Ltd, it breakthrough the bottleneck of the grinding mill, which processing capacity is 30% higher than the capacity of the R type raymond mill, at the same time it has the advantages of high qualification rate, low noise and vibration in grinding of the 325-400 mesh, more details please visit www.hengdamill.com.
