VSHM series new ring roller mill is developed by Dongguan Vsunny Machinery Co., Ltd. drawing on the same type of ring roller mills at home and abroad, in combination with its practical problems encountered in using this type of flour mill to process powder. It is ring roller mill equipment which is characterized by more practical, greater yield, and longer life of wear parts. Without the drying system, it can grind all kinds of qualified non-metallic mineral powder materials with moisture less than 8%.
Ring roller mills crush materials by impact, extrusion and grinding. There is plenty of moving clearance between the grinding roller mounted on the turntable and the axis pin. When the turntable revolves round the main shaft, the grinding roller will be stretched out to the grinding ring by centrifugal force, and press the grinding ring inner wall and rotate round the axis pin. Through the clearance between the grinding roller and the grinding ring, the material will crushed by the impact, extrusion and grinding of the grinding roller. The material is ground by the first layer of the grinding roller and grinding ring, then will fall into the second layer of the grinding roller be ground again as per the same principle, followed by the third and fourth layers. After the material is ground by the grinding roller in the last layer, it will fall onto the turntable under gravity and stretched out to the lowermost milling equipment, and brought to the interlayer between the inner and outer walls of the cylinder by negative pressure airstream, and once again rise to the top air classification system for separation. Qualified fine powder will pass through the classifier and enter into the pulse dust collector; coarse materials will be directly knocked to the grinding table and resettle in the pulverizing room for pulverization. The turntable is distributed in multiple layers. Thus, the material is sufficiently crushed to reach the desired fineness.
