性能优势

技术参数

1.High grinding efficiency:

By adopting advanced material layer grinding principles, the system's power consumption can be reduced by 20-30% compared to ball mills. As the moisture content of the raw materials increases, the energy-saving effect becomes more significant.

2.High drying capacity:

Materials can be dried using kiln hot air waste gases, and raw materials with a moisture content of up to 15% can be simultaneously dried and ground.

3.Small in size, and simple process flow:

It integrates crushing, drying, grinding, powder classifying and conveying，without the need for additional equipment such as drying, powder selection, and lifting. The workshop area only accounts for 70% of the ball mill system, and the space only occupies 50-60% of it.

4.Low noise, minimal dust, and clean operating environment:

The grinding roller and grinding disc do not contact directly during operation, there is no metal impact, and the noise is 20-25 decibels lower than that of the ball mill. The system adopts fully sealed negative pressure operation, with no dust and a clean production environment.

5.Low wear consumption:

Low wear consumption for the mill and low metal pollution for powder, generally metal wear consumption only 5-10g/t. the grinding roller sleeve can be flipped over for use, which is beneficial for extending its service life and reducing production costs. Easy to operate and maintain.

6.Particle size distribution balance

Grinding products have stable chemical composition, particle size distribution balance, which is beneficial to calcine.

工作原理

The material falls into the center of the grinding disc through the feeding device. The grinding disc, which rotates at a constant speed, under the centrifugal force to evenly disperse and flatten the raw material, forming a certain thickness of material layer. The material is simultaneously crushed by multiple grinding rollers on the grinding disc. Under the continuous drive of centrifugal force, the material continuously moves towards the outer edge of the grinding disc. When the material leaving the grinding disc encounters hot air entering the mill through the air ring and rises accordingly, it enters the classifier through the middle body of the mill. During this process, the material undergoes sufficient heat exchange with the hot air, and the moisture is quickly evaporated. The powder classifier controls the particle size of the finished product. Particles larger than the specified size are separated and fall back to the grinding disc. Materials that meet the fineness requirements enter the finished product silo through the powder classifier.
