Working principle and price of vertical roller mill

Vertical roller mill is a grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. It is widely used in the grinding of various solid materials in the cement, building materials, power, metallurgy, chemical, non-metallic ore and other industries. And superfine crushed powder.

 

Working principle

The vertical grinding motor drives the grinding disc to rotate through the reducer. At the same time, the hot air enters the vertical roller mill from the air inlet, and the material falls from the feeding port to the center of the grinding disc. Due to the centrifugal force, the material moves from the center of the grinding disc to the edge of the grinding disc. After being crushed by the grinding roller, the crushed material continues to move toward the edge of the grinding disc until it is taken away by the air flow at the wind ring, and large particles of material fall to the grinding disc and continue to be crushed.

 

When the material in the air flow passes through the upper separator, the coarse material falls from the cone to the grinding disc under the action of the guide blades, and the fine powder is ground out together with the air flow and collected by the system's dust collector. The collected powder is The product is ground mill. The material is dried in the process of contacting with the gas in the shell to reach the dry humidity required by the product. By adjusting the angle of the guide vane of the separator (small vertical roller mill is not adjustable) and the speed of the rotor of the separator, the required thickness of the product can be achieved.

 

Advantage

The advantages of vertical roller mills are: lower production investment costs, simple process flow of the vertical roller mill system, and small building area. It is equipped with a separator. It does not need to purchase powder separators and lifting equipment, which directly reduces the investment cost of the enterprise. Environmental protection, vertical roller mill adopts material layer grinding principle to grind materials, low energy consumption, select fully enclosed system, no dust, environmental protection; simple operation, convenient maintenance, vertical roller mill is equipped with automatic control system, simple operation, fast maintenance; Small, high utilization rate. There is no direct metal-to-metal contact between the grinding roller and the grinding disc during vertical roller mill operation. The metal consumption per unit product is low. The main disadvantages of vertical grinding are: hard and abrasive materials are not suitable for grinding, improper maintenance can lead to short service life; the fineness of the finished product of vertical grinding is too uniform, there is no reasonable particle grading, and clinker grinding has restrictions.

 

Price

Generally, the cost of materials, technology costs, market supply and demand, and the size of the model will affect its price.

1. The quality of materials usually affects the quality of equipment on the one hand, and directly affects the price of equipment on the other. Generally speaking, the better the material, the higher the cost, and the higher the price, but the quality of the equipment will be more reliable and the operation will be more stable. It will reduce part of the maintenance costs and reduce downtime. It is relatively cost-effective.

2. Technology cost is also an important factor affecting the price of vertical roller mills. The higher the technical input, the better the equipment performance, the better the use, the greater the profit for the user, but the higher the cost, the higher the price, the lower the technical content of the equipment, the lower the effect.

3. Model specifications. The vertical roller mill has various models, different output, different machine weights, different cost inputs, and different prices.
