Working Principle Of Vertical Roller Mill

  • 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. 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, Vertical Roller Millthe 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. 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. This cycle features of the way there:
  • 1. ring by adjusting the air valve, can change the product fineness can Shide mill bed load material uniformity and stability, improving the grinding efficiency;
  • 2. coarse particles in the external circulation, helps reduce Fan power consumption and overall system power.

Advantages Of Vertical Roller Mill

Most vertical roller mill patterns are positioned beneath a significant hopper, which feeds rock at the same time as other supplies in to your top rated during the mill. A significant, horizontal plate fits inside the entire body while in the drum, and rotates quite swiftly once the machine is in use. As components fall onto the plate, centrifugal force pushes them out in course of the edges to the circular plate. Massive rollers sit along the perimeter inside the plate, crushing and grinding sources upfront of these are in a position to fall off the edge. These rollers are powered by hydraulic fluid, which permits them to exert great force to care for challenging merchandise. The vertical roller mill serves as an alternate to traditional ball roller machines. Inside the ball roller, grinding wheels move within a steel drum to crush rock or stone. These rollers move in a rather random pattern, and have a tendency to produce merchandise of many sizes. They do not supply the consistency and helpful processing of a vertical roller mill. Like all grinding and crushing equipment, the LUM series vertical roller mill tends to call for regular maintenance on account of your abrasiveness in the stone within. These crusher machiner consist of a larger selection of parts and as a result are a good deal more complicated then a ball mill, which increases maintenance needs even further. A vertical roller mill also tends to cost better than other rock-crushing equipment.

Vertical Roller Mill Plants

Vertical roller mill is a kind of superfine grinding equipment, production and processing has been widely applied in foreign white non metallic minerals industry, the current domestic scale non metallic minerals also tend to use the equipment technical process to produce the product of TSP, barite, limestone and other non-metallic minerals, through cooperating with ultrafine classification equipment and processing equipment, to achieve product fine production.

LUM series vertical roller mill is used to solve the problem of low output, high energy consumption industrial mill technical problems, in the absorption of the European advanced technology and combining the heavy industry for many years of advanced milling machine design and manufacture theory and on the basis of market demand, large grinding equipment after years of painstaking research and innovation and creates

Vertical Roller Mill

LUM series vertical milling machine set, drying, grinding, fine powder separating and conveying into a whole, has the advantages of small occupied area, simple process, high grinding efficiency, low energy consumption, low noise, drying capacity, product fineness is easy to adjust, no dust pollution and convenient maintenance, reliable operation and so on, especially in the large grinding process, can fully meet customer demand, the main technical, economic indicators have reached international advanced level.

At present, LUM vertical mill in widely used in metallurgy, electric power, cement vertical roller mill, chemical industry, ceramic, non metallic minerals, power plant desulfurization, water slag, slag, slag, coal, cement clinker, glass, quartz, limestone and other industry large-scale material grinding and fine grinding processing.
