In metallurgy, mining, chemical, cement and other industrial sectors, there are a lot of raw materials and scrap material need to be processed by the crusher. For example, while in the cement plant, the raw material must be crushed to fire clinker and then the clinker will be grinded into cement. From the dressing plant, the ore is crushed into the required size of the grinding process by the crushing machine to make the monomer concentrator of the useful minerals. The grinding machine will grind the material that provide by the crushing machine into the monomer separation size. track mounted primary crushers In addition, during the chemical industry and power sector, the crushing and grinding equipment will crush and grind the raw material to increase the surface area of the material which can create favorable conditions to shorten the chemical reaction time of the materials. As to the building and road-building industry, they all need to use the crushing machinery to crush the raw
