How is the vertical mill grinding output controlled and maintained?

The vertical mill commonly used in industry is a kind of roller mill. The basic working principle is to place the material to be ground between the grinding roller and the grinding disc, and use the centrifugal force generated by mechanical or rotary force such as spring, hydraulic pressure to powder the material. Grinding, this equipment using the material bed for grinding has the characteristics of high grinding efficiency, low power consumption and low wear. There are many types and models of vertical roller mill. It is one of the most widely used grinding discs with rotating discs and rotating rollers.

The vertical mill is mainly composed of hot air ring road, grinding disc, grinding roller device, hydraulic device, vertical grinding reducer, grading device, machine seat, etc. The vertical grinding reducer is installed on the ground, and the grinding disc is mounted on the vertical mill reducer. The machine rotates the grinding disc around the vertical line of the ground, and the grinding roller crushes the material placed on the grinding disc under the action of the hydraulic pressure generated by the hydraulic device. The grinding roller rotates vertically without rotating the ground, and rotates around its own axis under the action of material resistance. The material in the annular region at the edge of the disc is carried by the airflow from the bottom to the upper classification device, and the fine powder passing through the classification device is discharged from the upper discharge pipe to the fine powder collecting device.

Compared with other types of vertical mills, the structure of SBM vertical mill has been greatly improved. It adopts a reducer with simple structure and reliable operation to improve reliability and facilitate user maintenance. The lubrication of the oil is improved by thin oil circulation lubrication. .

Vertical mill will ban more and more traditional milling equipment for a long time in the future. At present, China's cement industry has a large market demand for the vertical mill market. This demand is expected to continue for many years, and thus Will strengthen the development and innovation of science and technology, the survival of the fittest is impossible to stop, other milling equipment technology is also constantly making efforts and innovation, especially in raw material grinding, the grinding system has been shown to be better than vertical grinding The signs that the industry should welcome this innovative competition.

On the contrary, the main factors affecting the suppression are the grinding pressure, the system air volume, the speed of the classifier, and the size of the raw materials.

The application of the vertical mill is that the material layer is a cushion sandwiched between the grinding roller and the grinding disc. When the material layer is too thin, its buffering effect will be weakened and the vibration will increase. Suitable layer thickness. The stable material layer is the basis of the vertical grinding mill and the key to the vertical grinding operation. The pressure of material grinding is the decisive factor for stable and stable vertical mill operation. Within a certain range, the grinding pressure is proportional to the output of the vertical mill. When the current of the mill increases, the circulation volume increases, the pressure difference is too large, and the material layer passes. Thick, can increase the grinding pressure, thus reducing the material layer and stabilizing the grinding condition.
