Coal Pulverization System: Explosion Prevention and

Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying and conveying medium in the pulverizing process. The present coal process system is different with the traditional coal process system widely used. In the present investigation, pulverized coals with high volatile contents are used as deoxidizer in aluminum-

Coal mills for all requirements Gebr. Pfeiffer

Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using available hot process gases. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.

This carbonisation process removes impurities, like coal tar and coal gas, to produce coke. The red-hot coke is pushed from the side of each oven and quenched with water before being transferred by conveyor to the blast furnaces.

Coal mill feed belt monitoring band loading VEGA

To fuel the power plant boilers, chain conveyors must first bring raw coal from the bunkers. Feed belts (distributors) then transport the coal to the coal mill, where it is ground into dust and blown into the boiler. In order to ensure the fuel supply to the boiler in periods of full load, and especially low load, three redundant measuring systems are employed per feed belt.
