This paper describes a case study of coal pulverizer monitoring and analysis. It represents the partial work of a project called "Mill Advisor" which investigated the common operational and maintenance problems of the coal pulverizer.
Typical feed materials for Williams Roll Crushers include: bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells, and sewer sludge clinker. Single Roll Crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.
The Original Bearing Manufacturer Is Also The Best For Replacements. Messinger has provided many bearings for MPStype coal pulverizers. We have a long history of collaborating with OEMs such as Babcock Wilcox and Foster Wheeler, and with gear box manufacturers in specifying large main thrust roller bearings for use in their assemblies.
Overhauling a Pulverizer for Best Performance Typical Triggers for a Pulverizer Overhaul: • Prescribed maintenance interval (hours, tons throughput, months. • Noise, Coal Rejects excessive, Capacity Short. • Repair damaged or worn parts, grinding elements classifier components, etc.
The vertical roller mill (VRM) shown in Figure 4 is an air swept, mediumspeed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulicallyloaded grinding pressure through three grin ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal

Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw coal is then fed into the pulverizer along with air heated to about 650°F / 340°C from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel.
coalfired power plants. Even with alternative energy sources growing, there is still market demand and a need to support the many coal pulverizer units that are in operation today. We engineer and manufacture the large thrust roller bearings typically found in the gearboxes of coal pulverizer units at electric utility plants.

Design of Pulverizers . Every coal pulverizer is designed with a particular fuel grinding capacity, or throughput, at a certain Hardgrove grindability index (HGI), based on moisture content, a defined raw coal size, and desired fineness level. These factors must all be considered and are significant in discussions of pulverizer capacity.
Reliable coal pulverizer performance is essential for sustained fullload operation of today''s power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. BW''s pulverizers, found at power stations throughout the world.
