20TPH Heavy Calcium Carbonate Raymond Mill
The 20TPH heavy calcium carbonate Raymond mill is a high-efficiency grinding machine designed to produce fine powder for industries such as plastics, paints, rubber, and construction. This system ensures stable output, low energy consumption, and precise particle size control. Below is an overview of its optimized workflow and key features.
1. Working Principle
The Raymond mill operates by grinding raw heavy calcium carbonate (CaCO₃) between rotating rollers and a grinding ring. The crushed powder is then classified by an integrated air separator, where fine particles are collected while coarse material is reground.
2. Key Advantages
High Capacity: Processes up to 20 tons per hour (TPH) of heavy calcium carbonate.
Precise Particle Size: Adjustable fineness from 80 to 400 mesh (180–38 microns).
Energy Efficiency: Advanced grinding mechanics reduce power consumption compared to traditional ball mills.
Low Maintenance: Durable wear-resistant materials extend service life.
3. Process Flow
Crushing & Feeding: Large CaCO₃ lumps are pre-crushed and fed into thevertical mill.
Grinding & Classification: Rollers compress and grind the material, while a dynamic classifier ensures uniform particle size.
Collection & Packaging: Fine powder is collected via a cyclone and bag filter, then packed for distribution.
4. Optimization Tips
Use high-efficiency classifiers for better fineness control.
Implement automated feeding systems to stabilize production.
Regular lubrication and inspection of grinding rollers reduce downtime.
FAQ
Q1: What is the maximum input size for the 20TPH Raymond mill?
A: The recommended feed size is ≤30mm for optimal grinding efficiency.
Q2: Can this mill process materials other than calcium carbonate?
A: Yes, it can also grind barite, talc, gypsum, and other non-metallic minerals with similar hardness (Mohs ≤7).
Q3: How is dust controlled in the system?
A: A pulse dust collector and closed-loop airflow minimize dust emissions, ensuring a clean working environment.
Q4: What maintenance is required for long-term operation?
A: Regularly check grinding rollers, blades, and bearings, and replace worn parts to maintain efficiency.
This 20TPH Raymond mill offers a cost-effective and reliable solution for heavy calcium carbonate processing, ensuring high productivity and fine powder quality.
