stone crusher for sale

Raymond mill is a relatively common stone milling equipment in the milling industry. It has the advantages of reasonable structure, easy operation, strong working ability, small footprint, and low investment cost. It can grind all kinds of ores into powder, so that it has higher economic value, so it is very popular and loved by the majority of users. In general, the size, softness, hardness, water content, specific gravity, etc. of the material block are different, and the thickness of the finished product is also different. Therefore, in the case of a certain particle size required by the user, it is necessary to adjust the output of the milling equipment to meet the production needs.

The fineness adjustment principle of Raymond mill products: the high-speed rotation of the classifier will generate a certain centrifugal force, and the blower above the classifier will generate centripetal force. When the centripetal force is greater than the centrifugal force, the fine powder can pass through the blades of the classifier smoothly and be collected as finished products.

 

The higher the rotation frequency of the classifier and the faster the speed, the greater the centrifugal force generated and the coarser the powder. Therefore, the mesh size screening can be realized by adjusting the speed of the classifier. When the stone mill is working, the speed of the fan determines the size of the wind. When the material to be ground is light, if the wind is too strong, some powder that has not been completely ground will be blown into the powder collector; on the contrary, if the specific gravity of the material is large and the wind is too small, it will also affect the discharge.
