subject: Coal Mill And Ball Mill(12.2) [print this page] Coal mill: Coal mill:
As coal powder is the most important fuel in the power plant, The plant owners need coal mill or coal pulverizer to grind the coal to micro powders.
Raw coal (crushed) is fed through hopper at the top of the coal pulverizer and falls down to grinder ring to be pressed, crushed and milled into pieces by rollers. After the first crush, coal powder fall into the second and third layer. The pumping of the high-pressure centrifugal blower put the outside air into the coal mill. The coarse coal powder will be brought into the classifier.
As a pioneer in coal pulverizer, Shenbang has positioned itself well to meet the challenge of supplying coal mill with reliably quality and efficiently at the lowest cost.
Shenbang can manufacture and supply coal mill for all grades from hard coal to coke coal, our ball mill, High pressure Raymond mill, MTW trapezium mill, MTM trapezium mill, Coarse powder mill and micro powder mill is an ideal choice for power plants. The power plant can equipment different kinds coal mill to meet the required size.
Coal mill pulverizer used in cement plant:
Coal mill (coal pulcerizer) is the essential machine used in cement plant, because coal is the important raw materials in cement production line. Coal powder after grinding by coal mill enter into the rotary kiln toghter with cement raw meal for burning.
Coal powder has special strict demand in fineness. The finished size is 0.0445mm.
General in the complete coal powder production line, Crushing is the first step, using the coal crusher to crush coal into small particle. These small coal particle is grinded into powder by coal mill. The whole system consist of main coal crusher, coal mill, blower, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, cyclone collector device, classifier, high-pressure motor and muffler. The complete coal crushing and milling line is helpful to environment protection.
Coal Mill Type:
For coal mill, you have several types to choose.
ball mill, is widely used in cement industry. There are two types: wet ball mill and dry ball mill. ball mill, has simple structure, low cost, high capacity and convenient maintenance. The finished size is not even.
Vertical coal mill is also called vertical roller mill, and is also widely used in cement industry. Vertical cement mill is big in appearance with high capacity. For clinker grinding, we general use this vertical cement mill. The finished size can be upto 0.045mm.
Raymond mill is the eary grinding mill, but now is still used widely. The finished particles can be upto 0.044 mm, and have a good uniformity of fineness with passing screen rate as high as 98%.
