jaw. jaw crushers are run on belt drives driven by an electric motor or diesel engine. jaw crushers are used extensively throughout the aggregate and mineral processing industry. 1.2 working of crusher . crushing is the process of reducing the size of the lump of ore or over size rock into definite smaller sizes. based on the
throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. these operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust.
designed primarily for use by industrial minerals producers, this handbook contains detailed information on control technologies to address all stages of the minerals handling process, including drilling, crushing, screening, conveyance, bagging, loadout, and transport.
crushing and breaking. run-of-mine coal must be crushed to an acceptable top size for treatment in the preparation plant. typical crushing and breaking devices are feeder breakers, rotary breakers, hammer mills, and roll crushers. sizing. different cleaning processes are used on different sizes of coal.

mineral processing also called : 1-ore dressing 2-mineral dressing, 3- milling. in case of mineral processing one of the main aim is to regulating the size of the ore. we can define mineral processing as a process of physically separating the grains of valuable mineral from the gangue mineral, to produce an enriched portion or
mineral dressing (= orebeneficiation) the first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate

coal is a common energy source in the steel industry to extract iron from iron ore, and in the cement production process. the four main types of coal are lignite, sub-bituminous, bituminous, and anthracite. each type has varying amounts of hydrogen, oxygen, nitrogen, sulphur, and carbon, and as a result they have different uses.
