Post Finished fineness and yield
Construction Waste Crusher used in the power plant limestone desulfurization process popular, but the limestone desulfurization powder production and fineness of the relationship? Fineness and yield are dominated by limestone desulfurization mill equipment. Guangxi Guilin mill manufacturers vertical mill R & D personnel, said by adjusting the vertical grinding of various parameters, can improve the limestone powder production and fineness.

From the power plant limestone desulfurization mill grinding work principle, Construction Waste Crusher work, the motor through the reducer drive disc rotation, while the hot air into the ground mill, the material from the feed down the bottom of the disc, due to centrifugal force, the material from the center of the disc The edge of the disc is moved, and the annular groove on the disc is crushed by the roller pressing force. The material to be crushed is taken away by the airflow at the air ring, and the large particles are dropped onto the disc to continue to crush.

The material in the air flow through the upper part of the separator, under the action of the blade, the coarse material from the cone to the disc, the fine powder together with the air out of the mill, collected by the dust collector is vertical grinding products. The moisture-containing material is dried in contact with the hot air to achieve the required dry humidity of the product. The thickness of the product can be adjusted by adjusting the angle of the separator to guide the blades and the speed of the separator rotor.

From the above principle, we can see that the diameter and thickness of the grinding mill, the diameter of the grinding ring and the rotation speed of the spindle are the main factors that restrict the fineness and yield of limestone.

So, want to improve the yield and quality of limestone desulfurization grinding mill, can be achieved by the following methods:

1, the appropriate increase in vertical grinding roller rolling pressure, such as to take the pressure spring and hydraulic cylinder force;

2, increase the rotation of a week of grinding area, grinding area is equal to the height of the roller multiplied by the grinding wheel diameter;

3, to increase the roller and grinding ring contact probability, finishing the surface of the roller, so that the beginning of the roller and grinding ring into the grinding state, good contact, wear evenly;

4, increase the spindle speed of 7% to 8%, in the host power under the premise of improving the milling efficiency, in particular, improve the ability to process ultrafine powder;

5, increase the diameter of grinding roller and grinding ring, increase the grinding surface, increased by the amount of rolling material and per unit of the rolling pressure.
