Vertical raw mills are used to crush or grind materials into small particles. Vertical roller mills are widely used in the concrete and mining fields, and also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials.

     When the grinding mill is at work, all the grinding rollers are rolling in the ring channels. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers.

     Grinding roller consists of the thrust piece, roller shaft, roller tyre, roller hub, roller bearing, and rotary shaft seal etc. The grinding roller is located between the grinding table and the frame fixed by the frame, and accommodates two bearing, the bigger cylindrical roller bearing ensures radial load and the self-aligning roller bearing ensures axial load. The roller tyre is shaped symmetrically in order that it can be rotated in a determined condition of wear for the purpose of an optimum utilization.

      The grinding table and nozzle ring is composed of rotary parts and static parts. The rotary parts consists of the supporting tray, segments, taper cover etc. running with the grinding table carrier. The nozzle lamina connect together with the supporting tray revolves with the grinding table. The static parts are fixed on the mill housing. The inserted segments in the supporting tray are fixed with the cuneiform bolt. A taper cover on the supporting tray serves for distributing raw material and prevents dust and water from penetrating into the space below.

      Shenyang Gongda can provide the wear resistant castings for vertical raw / roller mills, such as roller tyres, grinding table, segments, grinding rings etc, made from wear resistant white cast irons, such as GX260CrMoNi 20 21, GX300CrMo27 1, Ni-Hard1,4, and treated for optimum mechanical properties. Roller tyres, grinding table, segments and grinding rings are also accurately machined to tight tolerances for precise fit.
