In the preparation and testing of geological standard materials, precious metal elements often exist as natural metals in ores, with:
- Uneven distribution
- High ductility
- High specific gravity
- Low hardness
- Low content
Improper selection of its processing machinery, tools and preparation process makes it difficult to crush. At present, the processing process of crusher coarse crushing, roller mill medium crushing, ball mill fine crushing and mixing or sample mixer mixing is commonly used.
Feasibility of Raymond Mill for Metal Ore
So, is it feasible to use Raymond mill for metal ore? It is feasible to process metal ore with Raymond mill.
advantages :
- Does not require screening during processing (because it adopts the principle of wind classification, which is equivalent to screening while processing)
- The processing volume is large
- The grinding effect is better than that of general ball mill
Simplified Process Flow
The processing of metal ore by Raymond mill can be simplified into two processes, that is, after the samples are sorted and dried, the ore samples are first coarsely crushed by the jaw crusher matched with the Raymond mill, and the samples are lifted into the sample bucket by the elevator, and then quantitatively, evenly and continuously fed by the electromagnetic vibrating feeder.
The Raymond mill directly processes to a particle size of less than 0.074 mm (or the required particle size), and then the samples are loaded into the ball mill for grinding and mixing evenly at one time, and the fixed partition in the special mixer is turned into a fully dynamic spherical grinding and mixing device with both friction and shear force, which greatly improves work efficiency and improves working conditions.
Advantages of Raymond Mill System
Raymond mill has the advantages of:
- Stable performance
- Simple process
- Convenient operation
- Relatively small footprint
- Strong systematization and complete set
- Can form an independent production system for raw material rough processing, transportation, powder making and packaging
Working Principle
After the material is crushed (jaw crusher, impact crusher, etc.) to the required particle size, the elevator sends the material to the storage hopper, and then the vibrating feeder sends the material to the grinding chamber of the Raymond mill host evenly and continuously. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring. The scraper scoops up the material and sends it between the grinding roller and the grinding ring. Due to the rolling of the grinding roller, the crushing purpose is achieved.
The fine powder after the material is ground is brought into the analyzer for sorting with the circulating air of the blower. The material with too coarse fineness falls back to the re-grinding, and the qualified fine powder enters the finished product cyclone powder collector with the air flow and is discharged through the powder discharge pipe to become the finished product.
Complete Raymond Mill System
The whole set of Raymond mill generally includes:
Among them, the Raymond mill host is composed of a frame, an air inlet volute, a scraper, a grinding roller, a grinding ring, a cover, a motor, etc. Cronus can provide a complete set of Raymond grinding system quotation. If you have relevant needs, please call us for details.
