Mar 29, 2017· The basic function of a pulveriser in a Thermal Power plant is to break down and crush the coal lumps into fine particle form before it is taken to the boiler for burning. Pulverisation of coal basically breaks the big coal lumps and increases the...
A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a builtin capacity cushion of pulverized fuel to take care of short interruptions in the raw coal circuit. The mill is pressurized and the airtightness is ensured by plenum chambers ...
Dec 13, 2011· A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only twothirds of the ball mills.
The ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed. Blending of explosives is an example of an application for rubber balls.

Pulverizers Coal Grinding Roller Mills William''s Vertical Roller Mill Pulverizers utilize centrifugal force to grind coal material while maintaining low operating costs. Featuring easily replaceable wear parts, automated process controls and infinite turndown thanks to VFAC drives, these machines are perfect to use as a coal mill.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
roller mill is operated with the rolls out of tram or out of parallel, significant thrust loads may be exerted on the rolls and bearings. In machines with straight bore bearings, the forces may be enough to cause the rolls to shift sideways in the machine, even contacting the mill frame.
