Description

Product Description Raymond mill is the equipment for mineral powder, coal dust and process gypsum, coal and other materials. It is widely used in metallurgy, building materials, chemical industry and mining to process powder. Usable Range It is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The series are used in grinding the non-flammable and non-explosive materials which has the Mohs hardness below 9.3, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore, etc. The size of final products changes from **3micron to **0 micron (0.**3mm~0.*4mm). Through the function of separator and blower, it can meet different customers’ demand. Structural Features The whole set of structure of Raymond Mill are as follows: Host Engine, Analytical Engine( Powder Concentrator), Pipeline Device, Air Blower, Finished Products Cyclone Separator, Jaw Crusher, Elevator, Electro-vibrating Feeder, Electronic Control Motor, etc. The host engine is composed by Rack, Volute for inletting air, Scraper Knife, Grinding Roller, Grinding Ring, Cover Shell, etc. Working Principles 1. The Jaw Crusher crushes ores and rocks into suitable feed particle size. 2. Elevator conveys the materials to storage silo. 3. The materials are conveyed to the grinding chamber of the host engine by electro-vibrating. The materials are grinded between grinding roller and grinding ring. 4. The fine materials which have been grinded are delivered to analytical engine for separating. 5. Fine powder which meets the request comes into the cyclone separator which will separate collect. 6. Finished products Features 1. High efficiency 2. Low energy consumption 3. Small area covering 4. Less investment 5. Non-pollution Operation Sequence 1. Boot Sequence: Elevator, Crusher, Analytical Engine, Air Blower, Host Machine, Feeder Machine 2. Shutdown Order: Feeder Machine, Host Machine, Air Blower, Analytical Engine. Performance and Advantages 1. Vertical structure, small area covering. Rough processing of materialsï&frac*4;Œconveying, powder making and packing are an independent system. 2. Comparing with other mill machine, its rate of through screen can reach to *9%. 3. Host machine adopts airtight gear case and belt wheel. It moves stable and reliable. 4. The main parts of Raymond mill all adopt high quality casting with high technology and ensure the durability of the whole set of equipment. 5. The electrical system of Raymond mill adopts centralized control system and has high level of automation.
