High Pressure Trapezoidal Mill

Learn More About High Pressure Trapezoidal Mill

1. Working principle:
The grinding roller rolls against the grinding ring under the action of high-pressure springs and centrifugal force to achieve high-pressure rolling.
The material is sent between the grinding ring and the grinding roller by the shovel for rolling, and the powder enters the analyzer with the circulating air, and the fine powder is collected as the finished product.
2. Wear and maintenance:
When the grinding roller and the grinding ring are worn, the high-pressure spring length can be adjusted to maintain constant pressure to ensure output and fineness.
3. Technology maturity:
The 4th generation mill has more than 30 years of manufacturing experience and stable performance.
4. Economic efficiency:
It can grind a variety of minerals to meet the needs of different specifications and particle sizes, with low investment and operating costs.
5. Lubrication system:
It adopts manual and automatic dual-purpose one-point electric cavity lubrication technology to reduce maintenance time and cost.
6. Energy consumption and efficiency:
High-pressure springs convert unfavorable factors into useful work, saving about 20-30% of power loss.
7. Environmental protection characteristics:
Unique air recovery system and advanced dust collector reduce environmental pollution.
8. MTW grinding line system composition:
Including mill, separator, blower, jaw crusher, vibrating feeder, hopper, dust collector, pipeline, powder remover, electric control cabinet, motor, etc.
9. Operation process:
After the bulk material is crushed by the jaw crusher, it is fed into the mill for grinding through the variable frequency belt feeder.
After the material is ground between the ring and the roller, it moves upward through the airflow, and the particles that do not pass through the separator are ground again, and the other particles are collected as finished products.
10. Environmental protection standards:
The system is equipped with a pulse dust collector, which meets the national environmental protection standards.

Working Principle

1. Material preparation:
Large pieces of material are first crushed by a jaw crusher to reach a size suitable for entering the mill.
2. Feeding:
The preliminarily crushed material is fed into the mill evenly and continuously by a variable frequency belt feeder.
3. Grinding:
The material is ground inside the mill by the high-pressure crushing pressure between the grinding roller and the grinding ring.
4. Powder separation:
The ground powder is brought into the analyzer with the circulating air for particle size separation.
5. Finished product collection:
The fine powder separated by the analyzer enters the cyclone powder collector with the air flow and is collected as a finished product.
6. Circulation grinding:
The larger particles that fail to pass through the separator are transported back to the mill by the circulating air and ground again with the newly entered material.
7. Dust removal and purification:
During the entire grinding process, the residual air enters the bag dust collector for purification to reduce dust emissions.
8. Wear adjustment:
When the grinding roller and grinding ring reach a certain wear, the high-pressure spring length is adjusted to maintain a constant pressure to ensure stable output and fineness.
9.Environmental emission:
The entire system is equipped with a pulse dust collector to ensure that dust emissions meet national environmental standards.
10.System monitoring:
The entire grinding line system includes an electric control cabinet and a motor to monitor and control the grinding process to ensure stable operation of the system.
