Vertical Mill - Energy Efficient Vertical Roller Mill for Limestone Slag Grinding

Description

Introduction to No.1 Limestone Vertical Mill:
Limestone vertical mill is a new type of grinding equipment designed and developed by our company, which combines years of experience in various vertical mill production, draws on domestic and foreign ultrafine grinding theory, and our R&D team. Limestone vertical mill is an ideal equipment in the grinding industry that integrates crushing, drying, grinding, and graded conveying of limestone. The stone powder vertical mill is well sealed, the system operates under negative pressure, environmentally friendly and clean, and meets national environmental protection requirements.

NO.2 Principle of Vertical Roller Mill Structure:

The electric motor drives the grinding disc to rotate through the reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the wind ring at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and the qualified fine powder is discharged with the airflow, Collecting in the powder collection device is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

NO.3 Vertical Mill Technical advantages:
1. Large output and high work efficiency.
2. The grinding roller bearings adopt a thin oil circulation lubrication method, which can ensure that the bearings work at lower temperatures and control the quality and purity of the lubricating oil, which is beneficial for extending the service life of the bearings
3. The combination powder selection machine has high powder selection efficiency and is equipped with a flipping roller device, which can flip the grinding roller out of the mill for easy maintenance
4. Compared with some other forms of roller mills, the hydraulic system of this vertical mill has lower operating pressure, lower oil leakage failure rate, and higher safety and reliability
5. Hefei Hengcheng vertical grinding process: grinding high fine limestone powder, the system operates efficiently and stably, completely eliminating external heat sources and reducing difficulties for enterprise project application
6. Compared with other limestone grinding systems, the vertical mill system can reduce power consumption by 40% to 50%
