Vertical Mill

Introduction

Vertical mill is a kind of large-scale grinding equipment useful in mining industry. It is widely used in cement, electric power, metallurgy, chemical, non-metallic mining and other industries. It integrates crushing, drying, grinding, grading and conveying. The vertical mill has high production efficiency and can grind block, granular and powdery raw materials into the required powdery materials.

What are the advantages of vertical milling machine?

Low investment cost

Because the vertical milling machine integrates crushing, drying, grinding, and grading and conveying, the system is simple, the layout is compact, the floor space is small, and it can be laid out in the open air, so it can greatly reduce the investment cost.

Environmentally and clean

The vibration is small and the noise is low. And the vertical mill equipment is sealed as a whole, the system works under negative pressure, no dust spills. The environment is clean and meets environmental protection requirements.

High drying efficiency

The hot air introduced into the mill from the outside is in direct contact with the powdery materials many times in the mill. Strong drying capacity can save a dryer for the mill system. It saves energy and can meet the requirements of materials with different humidity.

Low operating cost

The specially designed grinding curve makes it easier to form the material layer. A high rate of finished products can be obtained by one-time grinding. Especially since there is no grinding, the grinding energy consumption is greatly reduced. The main engine speed is controlled by frequency conversion to meet the needs of more materials.

Good quality of finished products

Daswell machinery uses the principle that the vertical abrasive layers are crushed and crushed by each other, without the pollution of the grinding media, thus ensuring the whiteness of the product. The content of materials <2μm in the finished product can reach 60%, which is conducive to the secondary classification and selection of finer products. Multi-round classification, high cutting precision. The product has moderate fine powder content, uniform particle size distribution and good adaptability.

How to choose the vertical mill

Vertical mill is a kind of large-scale production equipment, which can bring better benefits to production. It provides a good source of sand and powder required by various industries, so it is very popular. This situation also makes many manufacturers produce vertical milling machine for sale. In such a market situation, how should we choose a good production equipment?

By observing the use of the vertical milling machine, output and vertical mill maintenance account for a large proportion. Therefore, when purchasing, we need to pay attention to the following five aspects:

Production Volume

The output of the vertical roller mill in cement plant in the working process is a factor directly related to the benefit. Customers must strictly figure out what the capacity of the vertical grinding mill is in actual use.

Working principle of vertical milling machine

When the vertical mill is working, the main motor drives the grinding plate to rotate through the reducer. At the same time, the wind enters the vertical bead mill from the air inlet. The material falls in the center of the grinding plate through the discharge port of the screw feeder. Under the action of centrifugal force, the material moves evenly from the center of the grinding plate to the edge. When passing through the grinding roller table area on the grinding plate, it is crushed by the grinding roller. Then the coarse material is directly crushed, and the fine material is squeezed to form a material bed for crushing. The crushed materials continue to move to the edge of the grinding plate until they are taken away by the strong air current at the wind ring. The larger granular materials fall back to the grinding plate and continue to be crushed.

When the materials in the air flow pass through the upper separator, the coarse particles are returned to the grinding plate for grinding under the action of the separator blades. The qualified fine powder is discharged from the ultrafine vertical mill along with the air flow and collected by the powder collector of the system. The collected powder is the product of the ultra-fine vertical bead mill. When the iron and other sundries mixed into the material move to the edge of the grinding plate with the material, they cannot be blown up by the wind due to their own weight and fall to the lower cavity of the mill. Afterwards, the debris is scraped by the scraper at the bottom of the grinding plate into the slag discharge port and discharged out of the machine.
