How Vertical Roller Mill Works
It has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. In the gas flow is small, the meal can not be increased to enhance air flow, they would fall through the nozzle discharged outside the mill, bucket elevator to be transported to the feeder of Vertical Roller Mill, and was re-grinding mill feed people There are two circular disc slot, and roller to the tire shape, work pressure in the tank. Disc roller and the relative sliding velocity between small and roller can swing, even if the roller sleeve and the disc after the liner wear can guarantee a good abrasive, will not affect the grinding effect. Roller symmetrical structure, one side can be upside down after use and wear. Material grinding process: hydraulic pneumatic roller device through the pressure applied to the material on the crushing of materials, the materials have been moved to crush the edge of disc, from the disc around the nozzle from the exhaust air to improve these materials to Separator.Meal to separate returns after a concentrated mill, fine powder was collected in the precipitator unloading.
This cycle features of the way there: ring by adjusting the air valve, can change the product fineness can Shide mill bed load material uniformity and stability, improving the grinding efficiency; coarse particles in the external circulation, helps reduce Fan power consumption and overall system power. Announcing a New Product Line! Stedman has officially rolled out a new air swept fine grinding system. This fine grinder has unparalleled particle size distribution when compared to a traditional ball mill or Raymond Mill. The consistent wear and long life grinding zone components make this fine grinder one of the best on the market. We understand that having a fine grinder with consistent results is crucial to maximizing efficiency and profitability of your product.
Features of Vertical Roller Mill. Composite separator improves the efficiency of the powder. With the function of automatic lifting and falling , can realize no-load starting. Welded type arc plate is used for sealing, it features simple structure, reliable performance, well-sealed structure. By means of the roller swing-out device, the grinding rollers can be turned out of the mill, which is in favor of maintenance. The limit mechanism avoids the fiction and crash of metals between grinding roller and grinding plate, increasing the rotating stability and security. Operating pressure of hydraulic system is low, can reduce the leakage failure and the mill vibration , is good for operation and management. The centralized circulating oil lubrication is applied to the grinding roller bearings, which ensures the bearing operate at constant temperature and with pure oil, so that longer service life is achieved.
