Overview Of Our Mills 183 Christian Pfeiffer
vertical mills flexible mills with integrated separator. the vertical mill enables high energy economy, and convinces with low specific wear values. drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.hlm series vertical roller mill is a kind of advanced mill developed by hongcheng based on two decades of r&d experience and introduction of foreign advanced technology. It features in a combination of drying, grinding, classifying and conveying. hlm vertical grinding mill, has high grinding efficiency, low power consumption, large feed size, product fineness easy adjustment, equipment process but for vertical roller mills, the growth rate of that of material will gradually decrease. from this point of view, roller press is superior to vertical mill. In roller press, the contact area between the two rollers and the material is small; the material is ground by only passing through the roller press once due to the large grinding ratio.grinding and drying test with vertical roller mill for the study of the grindability and drying characteristics of high-moisture coal with the vertical roller mills, grinding and drying tests were carried out using a reduced-scale model of a vertical roller mill to verify the continuous and stable operation and drying characteristics.
