1, pipe grinding and ball milling little difference, low cost, low cost, small footprint, generally suitable for small-scale production, the diameter is generally below 4M, can be used alone, generally as a clinker into powder;
2, vertical mill is generally divided into 2 categories, raw material grinding and slag grinding, the relative cost of relatively high, of course, the amount of powder is generally larger;
Raw material grinding: The raw material mill uses a large cover, that is, the end cap and the hollow shaft are integral casting parts. In the large end cap and discharge system, a unique streamlined design is adopted to reduce the ventilation resistance, increase the effective volume, facilitate the discharge, and increase the output of the mill. Raw material grinding is widely used in building materials, metallurgy, electric power and chemical industries for grinding (drying and grinding) of cement raw materials and other materials.
The difference between raw mill and cement mill:
The raw material mill is generally a vertical mill, and the fineness of the material is not required. The cement mill is clinker and other mixed materials are the cement, usually ball milling, the fineness of the cement is required, and the ball mill can control the grinding through the grading of the grinding ball. The fineness of cement.
