The stone crusher is mainly used to crush stones for construction industry or mine industry. It is characterized by reliable operation, simple structure, high production, easy maintenance and high operating efficiency. Generally, the stone crusher consists of cone crusher, impact crusher and jaw crusher. It is an essential equipment in both sand making process and stone crushing process.The features of micro powder stone grinding mill are the following: 1. The stone grinding mill of is high efficient (twice as much as jet mill, mixing grinder and ball mill equipment) 2. The spare parts of stone grinding mills can serve much longer time (2-3 times longer than that of impact mill or turbo mill. 3. High safety and reliability of the stone grinding mill (no rolling bearings and screws in the grinding cavity, so no problems caused by the wear of bearings or screws) As a professional and the best grinding machines manufacturer in China, Hongxing Machinery is always ready to provide the superior crushing and grinding machine for sale with the best quality and the most competitive price such as conveyor belt system, spiral chute separator. 4. The series Stone Grinding mills are characterized by high fineness (final size: 325-3000 mesh, D97 5 micron) 5. Environment-friendly Raymond mill also be called high pressure suspension grinding mill, is a kind of roll grinding machine, is suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.powder machine:...
