Raymond Mill Provide Gold Mine Tailing Extraction Technology In India
1906 CVGrueber created Curt Von Grueber machinery factory in the southern suburbs of Berlin. 1925 ECLoesche summed up the first generation of Raymond coal mill shortcomings about use features and structure and decided to further improve the structure of raymond mill, then developed a grinding mill opposite principle and this is called modified Raymond.
Until now, Raymond Mill has great changes intechnology and the appearance and it is very popular in the masses of customers.
Raymond Mill Common Sense
hardness and mohs hardness
Hardness: because it is destructive testing, so the original unpolished precious stone or ore can be used. there are two types of hardness scales, one is absolute hardness, and the other is a Mohs hardness (a relatively hardness).
Mohs hardness: ten minerals in common with each other as a standard scraping hard to distinguish what what soft, mineralogical or gemological customarily been used on the Mohs hardness. Mohs hardness in ten stages as follows: talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, diamond.
Mesh is greater, indicating the material finer granularity; mesh is smaller, the larger particle size. Sieve size particles that can pass through the screen mesh size to 1 inch (25.4mm) width of the screen indicates the number of the mesh, so called mesh.
Raymond mill is a commonly milling equipment, mainly used for barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock , plaster, glass, insulation materials, etc. Mohs hardness of not greater than 9.3 and humidity below 6% of non-explosive mineral, chemical, construction and other industries more than 280 kinds of material for high fine powder generation and processing.
Product AdvantageHigh-performance separator and optimised airflow guarantee large separation efficiency and lower strain reduction for power cost savings.Unusually huge rollers allow coarse feed and make sure a thick grinding bed for greatest uptime.All affect forces and dynamic reactions are compact and vertical and therefore simple to accommodate prevents mill stops.Segmented put on components for table and rollers enable utilization of one of the most wear-resistant supplies and/or hardfacing for lengthy daily life.Reversible roller segments be certain large materials utilisation.
Feed sluice assures very low false air movement and regular feed movement for minimal electrical power consumption and optimum mill manufacturing.Raw mill is very easily adaptable to large airflow demanded by primarily moist or simple to grind materials.Operational Principle
Raw mill makes use of strain and shear produced in between the rollers as well as the rotating table to crush and grind raw supplies. Feed materials is directed onto the grinding table through the feed chute. The rotation in the grinding table accelerates the materials in the direction of the grinding track and passes it beneath the rollers. Coarser materials and larger humps drops with the nozzle ring ¨C and it is finally recirculated to the feed materials inlet. Moisture evaporates just about right away because the fuel stream carries the finer portion of materials towards the separator. The separator makes it possible for materials which has reached the expected fineness to depart the mill and sends oversized materials back for even further grinding.
