High-pressure Raymond mill integrates fine grinding, drying, grinding, powder selection and conveying. No additional drying, powder selection and lifting equipment are needed. Dust-bearing gas can be directly collected by high-concentration bag dust collector or electrostatic precipitator. The layout is compact and can be arranged in the open air. The building area is about 70% of the ball milling system and the building space is about 50-60% of the ball milling system. Therefore, the process flow of high-pressure Raymond mill is simple, occupying a small area and occupying a small space, making the construction cost low.
- 1. High grinding efficiency and low operating cost.
The energy consumption of the grinding system is 20-30% lower than that of the ball mill, and the energy saving effect is more remarkable with the increase of the moisture content of the raw material. The roll sleeve can be turned over and used, which is beneficial to prolong the service life and reduce the production cost.
- 2. Easy and reliable operation.
Equipped with rare lubrication station, roller bearings are lubricated by concentrated circulation of dilute oil, which ensures that bearings work under low temperature and pure oil conditions, prolongs service life, and makes the equipment running system run continuously and reliably.
- 3. The equipment has large drying capacity and wide grinding materials.
Raymond mill uses hot air to convey materials. When grinding materials with high moisture content, the inlet air temperature can be controlled so that the final moisture of the product can meet the requirements. In high pressure Raymond grinding mill, materials with 15% moisture can be dried and ground, which has a wide range of applications. Even if the ball mill is dried, only 3-4% moisture can be dried.
- 4. The product quality is stable and the particle size distribution is uniform.
The material stays in the high pressure Raymond mill for only 2-3 minutes, while in the ball mill for 15-20 minutes. Therefore, the chemical composition and fineness of high-pressure Raymond mill products can be quickly measured and corrected, and the quality is stable.
- 5. Environment-friendly, low noise, less dust.
Raymond mill has no direct contact between rollers and grinding discs, no collision of steel balls and metal impact of steel balls on lining plate in ball mill. Therefore, the noise of Raymond mill is low. In addition, the high-pressure Raymond mill equipment uses a fully sealed system, which operates under negative pressure, without dust, and has a clean environment.
