Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.
feed-3-300x225. Rotary Feeders. CSE Bliss Rotary Feeders are designed to provide a steady, consistent supply of material across the full inlet of the hammer mill. This helps to achieve the hammer mill's full grinding capabilities. The rotary feeders require a VFD to allow for adjustments of the feed rate to the hammer mill
The counter pressure reduces the noise generated by the mill and is adjustable depending on the coal properties and required coal fineness. During operation, both pressures are adjusted proportionately to the feeder speed by means of pressure control valves to achieve an optimized grinding force characteristic throughout the mill load range.
The ATOX® raw mill uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials. Feed material is directed onto the grinding table by the feed chute. The rotation of the grinding table accelerates the material towards the grinding track and passes it under the rollers.

The air-swept coal mill is used for grinding and drying coals. It mainly consists of feeder, main bearing, rotation device, transmission device, discharging device, high pressure start-up device and lubricating system. It is widely used in the cement making industry, steam power industry, metallurgy industry, and chemical industry and so on.
Steam Jackated Rotary Airlock These airlocks are specially designed to feed lumpy materials like coal with high fines content which tend to pack due to moisture, there by jamming rotor. The housing is of a special design with side entry and jacketed to pass steam to remove moisture from the material being handled.
When their coal supply was interrupted, plant personnel had only 15 minutes to restore feed before the pre-calciner and rotary kiln shut down. Coal was transferred from outdoor stockpiles to a pulverizing roller mill via a belt conveyor and a triple-gate dump valve located at the mill inlet.

Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
