Talc is an important industrial mineral with a Mohs hardness of 1. It has lubricating, fire-resistant, acid-resistant, and insulating properties. Talc is widely used. It increases smoothness and gloss in papermaking and improves printing effects; it improves rigidity, stability, and heat resistance in plastics; it increases volume, reduces costs, and improves performance in rubber. It is also used in cosmetics, medicine, ceramics, coatings, etc.
Raymond mill: the "golden partner" of talc processing
Raymond mill is the "golden partner" of talc processing. Its working principle is unique: the material enters the main machine through the feed hopper, and the transmission device drives the central shaft and plum blossom frame to rotate. The grinding roller revolves around the center and the grinding ring and rotates on its own. The scraper shovels the material into the gap between the grinding rollers to form a padding layer, which is crushed and powdered by centrifugal force. The vertical structure of the whole machine saves space and forms an independent production system. The transmission is stable and reliable, the important components are durable, and the maintenance cost is low. It is suitable for non-flammable and explosive materials with Mohs hardness ≤9.3 and humidity <6%, especially talc. Talc has a Mohs hardness of 1. Raymond mill can grind it easily and accurately control the finished product particle size of 80-325 mesh, and some can reach 600 mesh, meeting the needs of various industries.
Analysis of the process of processing talc with Raymond mill
The process of processing talc with Raymond mill includes crushing, grinding, grading and collection. In the crushing stage, a jaw crusher is used to crush large pieces of talc to 15-50mm. In the grinding stage, small pieces of talc are sent to the silo by a bucket elevator, and then sent to the Raymond mill by an electromagnetic vibrating feeder. They are crushed into powder through the friction between the grinding roller and the grinding ring, and the fineness can be adjusted to 80-600 mesh. In the grading stage, the fan and the analyzer work together to screen the talc powder. Those with unqualified particle size return to the mill, and those that meet the requirements enter the collection stage. In the collection stage, the talc fine powder enters the collector through the pipeline system, is separated and collected by the cyclone dust collector and the pulse bag dust collector, and finally transported to the finished product silo for packaging.
The advantages of Raymond mill in talc processing are fully demonstrated
Raymond mill has excellent performance in talc processing and has become the first choice of enterprises. It has high output and significant energy saving and consumption reduction, and its energy consumption is reduced by 20%-30% compared with traditional equipment. Environmental protection meets standards, fully sealed design with high-efficiency dust collector, dust emission is far lower than the national standard, noise is low, and it conforms to the concept of green development. High cost performance, compact structure, small footprint, easy operation and maintenance, long-term stable economic benefits.
Operation points and maintenance guide of Raymond mill
Operation points:
Before starting the machine, check the bolts for tightening, clean foreign matter, confirm lubrication, and check the direction.
• Start-up sequence: bucket elevator → jaw crusher → analyzer → blower → Raymond mill main machine → electromagnetic vibrating feeder.
• Feed evenly, adjust the feed speed according to the output and operating status, and stop the machine in time to check abnormalities.
• Fineness adjustment: through the analyzer speed and air volume control, small range adjustment and sampling detection until the standard is met.
• Shutdown sequence: feeder → main engine → blower → analyzer, to ensure material discharge.
Maintenance Guide:
• Regularly inspect and replace wearing parts such as grinding rollers, grinding rings, scrapers, etc., and choose reliable quality accessories. Check and tighten the bolts and nuts to ensure the stability of the equipment structure. Reasonably select lubricants, refill regularly, and keep the lubrication system unobstructed. Clean the dust on the surface and inside of the equipment regularly,
• Install dustproof devices to maintain a clean environment. Check electrical circuits and components, clean them regularly, and comply with electrical safety operating procedures.
Conclusion
• Cronus Raymond mill is the first choice for talc processing companies. It has high production efficiency, guaranteed quality, and low cost price, which injects momentum into the development of the talc processing industry.
