Product Description

Description of Vertical Coal Grinding Mill

Vertical Coal Grinding Mill can be used to grind materials with a diameter less than 44mm on the rotary disc by rollers with certain pressure. It has advantages of high grinding efficiency, strong dry capacity, easily adjustable grinding size, low noise, low power consumption, simple process flow, low wear rate, low operation costs, etc.It is mainly comprised by segregator, grinding roller, grinding disc, pressure device, speed reducer, electromotor, shell, and more.

 

Features of Vertical Coal Grinding Mill

 

1. High grinding efficiency and low power consumption. This kind of machine consumes 20-30% lower power. And with the growing of moisture content, its energy-saving effect will be more obvious.

2. Strong dry ability. Air is used to send materials, and the temperature of the air can be controlled according to the moisture content of materials. And this mill can be used to dry materials with moisture content as high as 12~15%, which is much higher than the special dryer.

3. Large feeding size. The feeding size can be as large as 5% of the diameter of the grinding diameter, that is, 40 to 100mm. Therefore, secondary grinding is unnecessary for large-scale and medium Vertical Coal Grinding Mill.

4. Stable chemical composition and even particle size products. 5. Simple process flow and small in size.

 

There is a segregator in the Vertical Coal Grinding Mill, which makes powder separator and elevator unnecessary. Grinded dusty air can directly enter into the environmental protection equipment. So its process flow is quite simple and compact. Its structure size is only 70% of that of the ball mill, and its building space is only 50~60% of that of the ball mill. 6. Low noises, few dust, and environment friendly. There is no direct contact between the grinding rollers and grinding disc, so there is no impact sound caused by the colliding between the steel balls or between the steel ball and lining plate. Compared with ball mill, its noises are 20~25 decibels. Besides, our LM Vertical Coal Grinding Mills are sealed totally, so the whole system can work under the negative pressure condition. In this way, raising dust is vastly reduced. 7. Low metal wear rate, long service lifespan and high utilization rate of lining plate and grinding rollers. Because there is no direct contact and impact between metal components, its accessories have less wear and long service life. When this Vertical Coal Grinding Mill processes medium hardness cement materials, its grinding rollers and lining plates can work normally as long as 8,000h.
