Fly Ash, Coal Handling and DirectFiring Mills for Power Plants. With one eye on the future, Claudius Peters is renowned for developing coal handling equipment and low energy systems for fly ash handling which are reliable with lower maintenance costs and higher availability.
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill startup, stopping coal feed on shutdown, or when equip ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal .
the milling plant (throughput and particle fineness) required improvement, and the average throughput must be increased without sacrificing the product quality. Monitoring of the coal mass flow was achieved by means of an online Mill Energy Balance. The Particle Size Analyser evaluation

Mill Reject Handling Systems Mill Rejects are efficiently handled through the Schenck Process revolutionary mechanical conveying system utilizing of our chain conveyor and chain bucket elevator. The Schenck Process Mill Reject Handling System is compact, fully enclosed and therefore negates all environmental related problems, providing trouble free operation.
· INPLANT COAL HANDLING The InPlant coal handling system deals with feeding of coal from live storage to the furnace. It includes various equipment's for transfer of coal like belt conveyor, screw conveyor etc. the equipment needed to weigh the quantity of coal for feed. In case of pulverized coal firing system, it requires large no. of equipment's like chutes, pulverized mills, feeders ...
Operation Philosophy of Mill Reject Handling System (MRHS) The pneumatic cylinder operated plate valve at mill outlet (Pyrite Hopper inlet) is normally kept open. Mill Rejects from coal mill will drop into the Pyrite Hopper through the grid. Oversize material will be retained on the grid.
· In the crusher a highspeed 3phase induction motor is used to crush the coal to a size of 50mm so as to be suitable for milling system. Coal rises from crusher house and reaches the dead storage by passing through transfer point 8. Stages in coal handeling power plant. Equipment used in a coal handling plant 1. Pull chord switch.
Coal handling. Generally, the coal handling components are determined by the design and requirements of the boiler  and the capacity of the thermal power plant. Coal can be delivered by any means of transportation allowing for bigger volumes and weights depending on the loion of site.

Abstract. A system for the safe handling of pulverized coal includes conventional coal pulverizing and drying equipment, with cyclones and bag filters added, the latter serving to separate the fine coal from the conveying gas (usually air); and explosion suppression and fire suppression systems, .
Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
