It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Impact crusher is generally used as a secondary crushing equipment. It can process materials with a side length of less than 1300 mm. Its compressive strength can be as high as 350 MPa. It has the advantages of large crushing ratio and cubic particles after crushing. The impact crusher has a shaping function. It is suitable for crushing medium-hard materials, such as limestone crushing in cement plants, with the advantages of large production capacity and small discharge particle size.
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace.
