How to adjust the quality fraction and fineness of the control grinding?

The grinding mass fraction refers to the mass fraction of the pulp in the grinding machine. Grinding fineness refers to the specified level of content in the mill discharge. The grinding quality fraction and the grinding fineness are interrelated and mutually influential, and the production operation is mainly controlled by the adjustment of the ore to the ore water (post-water). In the case of open road grinding, the factors affecting the grinding quality fraction are the nature of the ore (mainly the particle size composition), the ore supply and the ore supply. Factors affecting the fineness of grinding, in addition to the ore size composition, there are grinding quality points and balling system. When the nature of the ore is changed, if the coarse particles are increased, the amount of ore should be reduced to reduce the post-water, and the grinding mass fraction should be increased to ensure the fineness of the grinding. If the fine particles are increased, the post-water should be increased and the amount of ore should be increased appropriately. Reduce the smash. Under the condition that the ore property and the medium condition are kept unchanged, the general grinding fineness increases with the increase of the grinding mass fraction within a certain range, and vice versa. In short, the grinding mass fraction is adjusted by adjusting the amount of water supplied, thereby controlling the fineness of grinding. In closed-circuit grinding, the situation becomes more complicated, adding a factor in the amount of sand return. When the water supply is certain, the increase of the original ore and return sand will increase the grinding quality score, and vice versa. In addition to the influence of the amount of sand returned, the grinding fineness is also affected by the classification efficiency. When the amount of sand returned is large, the grain size composition of the whole ore is changed, the amount of fine particles is increased, and the grinding speed is fast. The grinding quality fraction should be appropriately reduced, and the ore discharge speed should be increased to reduce over-grinding. When the amount of sand returned is reduced and the ore is coarser, the post-water should be reduced to increase the grinding quality.

Saddle  wiper arms are typically used on windshields that are taller than they are wide - like tugs, fishing vessels, transit buses, etc. 
They have two parallel struts and move the Wiper Blade from side to side. They are structurally strong - to handle large wiper blades, and require larger, more powerful motors. 
Unlike some competing models, both the drive and slave arms of these Wexco pantographs are strong, heavy duty struts (rather than a drive strut and a slave tube). 
• All pantograph arms have saddle style blade attachments 
• Heavy duty construction you can see and feel when you pick the arm up 
• Black finish is black powder-coated stainless steel 
• Silver finish is bare matte (shot peened) stainless steel
