The working principle of MTW175 limestone grinding equipment is mainly based on its unique design and grinding mechanism. Here's a brief description of how it works:
1. Feeding and preliminary crushing:
• Limestone raw materials are first fed into the feed port of the equipment.
• Through the feeding device, the limestone is evenly transported into the inside of the mill.
• Inside the mill, the limestone may first undergo preliminary crushing to reduce its particle size for subsequent grinding.
2. Grinding process:
• Grinding is the core step of MTW175 limestone grinding equipment.
• The equipment is equipped with high-speed rotating grinding rollers and fixed grinding rings (or grinding discs).
• The limestone is crushed, sheared, and ground between the grinding rollers and the grinding rings, gradually breaking into finer particles.
• The distance between the grinding roller and the grinding ring can be adjusted through the adjustment mechanism to control the particle size of the discharged material.
3. Grading and collection:
• The ground limestone particles enter the classification zone.
• The classification area is usually equipped with rotating classification wheels or airflow classification devices, which can sort particles according to their size.
• Fine powder that meets the particle size requirements enters the collection system through a classification device, such as a cyclone collector or bag dust collector.
• Coarse particles that do not meet the requirements are returned to the grinding area for grinding again.
4. Conveying and packaging:
• The collected limestone fine powder is transported to the finished product bin through conveying equipment (such as a screw conveyor or pneumatic conveying system).
• In the finished product silo, the fine powder can be packaged or further processed.
5. Dust removal and environmental protection:
• During the entire grinding process, a certain amount of dust will be generated.
• The MTW175 limestone grinding equipment is equipped with a dust removal system (such as a bag dust collector) to collect and process this dust to ensure a clean and environmentally friendly production environment.
In general, the MTW175 limestone grinding equipment processes limestone raw materials into fine powder products that meet the requirements through the steps of feeding, grinding, grading, collection and dust removal.
