LM Vertical Mill for Blast Furnace Slag


LM Slag Vertical Grinding Mill is the environmental friendly vertical mill, designed by Henan Zhenyuan Science&Technology Co.,Ltd to positively answer the call of the national energy conservation and pollutant emission reduction policy. After years of accumulations, we, in cooperation with senior experts and institutes in manufacturing vertical mill at home and abroad, developed this environmental friendly and energy-saving vertical mill. At present, the capacity of this mill has completely reached an annual output of 0.3, 0.45, 0.6, 0.9 and 1 million tons. This machine is reasonable in overall structure, advance in technology and the operation is
stable. Its most technical and economic indicators have reached the international advanced level.

Blast furnace slag (slag) is an industrial slag,during iron smelting, excluded from blast furnace. Due to its high physical and chemical activition and potential hydraulicity, slag is widely used as admixture in cement industry. As commonly used slag grinding equipment, slag vertical mill mainly consists of refiner disc, roller, separator, pressing device, monitoring device, gearing device, sprinkler system and coarse powder recycling outside system, etc. These parts finish slag grinding together.

Vertical Slag Mill has integrated drying, grinding, separating, delivering into one. Therefore, it has so many advantages such as,high grinding efficiency, big drying capacity, flexible control on product fineness, low noise, low power consumption, simple process,less frication and saving operating cost, etc, which makes it very suitable for large-scale grinding. Its main technical, economic indicators all reached the international advanced level.

Vertical Roller Mill Excellent Features:

  • High efficiency: using rollers grind materials on the grinding disc directly consuming less energy. Compared with ball mill, it saves energy consumption by 30%~40%.As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
  • Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is of high quality, so life lime is long and wear is less
  • Stable Yield and High Quality.As materials stay in the mill for a short time, it is easy to detect and control the product’s particle size and chemical composition, which reduces repeated milling and stabilizes product quality. Moreover, roller shell and lining board don’t contact directly, so few iron are invelved into the product and these iron can be easily removed. Thus, to grind white or transparent materials, vertical mill produce product with high whiteness and purity. It is equipped with one limiting device, which prevents the roller from contacting with the liner directly, to avoid the destructive impact and severe vibration

Vertical Roller Mill Working Principle:

Vertical Roller Mill Working Principle

Full set of vertical mill consists of: main unit, bucket elevator, adjustable hopper, sealed constant feeder, air heating furnace, dust remover, blower and silencer.

The motor drives the grinding table to rotate by reducer, and the hot air goes into the inner part of machine at the same time. The materials fall down to the center of grinding table from feed opening. Driven by the centrifugal force, materials move evenly to the edge of the grinding table, and they are grinded by the rollers when going through the rollers’ track. Bulk materials are crushed, while fine materials form material bed after being squeezed and experience intergranular crushing. Grinded materials move on to edge of the grinding table until being taken away by strong airflow at the wind ring, in which larger materials fall to the grinding table by gravity and reground. The others enter the separator being graded. Under the influence of separator blades, materials that do not meet fineness requirements return to the grinding table to be grinded, while the standard ones go into dust collector through the pipes and are discharged as finished products from the discharge device. Irons and other impurities, which cannot be lifted by the wind for weight, move together with materials to the edge of grinding table and fall to the lower cavity, and then they are scraped i1 Setnto the slag discharge opening by stripper plate which is fixed at the bottom of the grinding plate and discharged out of the machine.
