Roll Crushers. Single Roll Crushers are used to crush ROM Coal (1000 mm 1500 mm size) to () 200300 mm size. In Coal Preparation Plants the coal feed is to be further crushed to () 25 mm size by using Toothed Double Roll Crushers. Smooth Double Roll Crushers can be used for crushing up to () 5mm.
Ring Granulator type crusher are used in coal handling plant for crushing coal to a size suitable at power stations prior to pulverization. Crushing Principle Of Ring Granulator Type Coal Crusher Ring Granulator crush material by a combination of impact and rolling compression.
The major advantage of this type is that the coal can be carried directly into the powerhouse up to the point of consumption. 5. Transportation by Pipeline. In this method, the coal in the form of slurry is directly supplied from the remote mines to the strategically located thermal power plants through pipelining.
6 Construction and Maintenance of Belt Conveyors for Coal and Bulk Material Handling Plants also oscillating horizontally. This phenomenon results in internal agitation to the material on belt and therefore the material's external faces assume inclination at surcharge angle.
Usually a thermal power plant and coal mining area has reservoirs, bunkers, and stockpiles where coal is stored. In coal handling system due to lack of infrastructure, human labour is involved in the continuous monitoring of coal storage tanks. The ambient environment near the coal mining area includes toxic chemicals and gaseous liquids which are
Crushing efficiency has been defined in the literature from the power consumption point of view. But while operating a process plant, it is more important that the crushing efficiency is defined in terms of the requirement of subsequent process. The Process plant has been designed for coal size 13 mm ( 80 % passing).
4. Introduction: • Objective of CHP is to supply the quanta of processed coal to bunkers of Coal mills for Boiler operation and to stack the coal to coal storage area. • Coal is a hard black or dark brown sedimentary rock formed by the decomposition of plant material, widely used as a fuel. • A piece of coal called Coal Lumps.
