Slag Vertical Roller Mill | Slag Grinding Mill Manufacturer

Description

A slag mill is a specialized grinding system designed to process granulated blast furnace slag, steel slag, and similar materials into fine powder for cement and building material production. Compared with traditional grinding systems, a slag vertical roller mill applies grinding force directly to the material bed through rollers and a rotating grinding disc, resulting in higher efficiency and lower power consumption.

Application Industries

Suitable materials include:

Blast furnace slag
Steel slag
Power plant slag
Phosphorus slag
Other industrial solid waste

Typical industries:

Cement plants
Steel plants
Power plants
Building materials factories
EPC projects

Working Principle

Slag vertical mill is a kind of grinding equipment to dry and grind slag by means of negative pressure air sweep. During working, the slag is evenly fed through the conveyor and falls into the center of the grinding disc from the lower feeding port. The main motor drives the grinding disc to rotate through the reducer, and under the action of centrifugal force, the material moves evenly from the center to the edge, while being squeezed by the grinding rollers into powder grinding.

The crushed material continues to move towards the edge of the grinding disc, while the hot air enters the inside of the machine from the air inlet, and the qualified fine powder will be picked up by the airflow entering from the wind ring and collected by the powder collector to become the finished product of the slag vertical mill. Larger particles are scraped up by the scraper blade for further crushing and grinding.

Advantages



Vertical Structure

Our slag vertical mill is designed with a vertical structure, covering a small area and saving production space. Its compact design makes the equipment arrangement more flexible and adaptable. Additionally, the slag vertical mill adopts sturdy and durable materials and a precise manufacturing process to ensure the stability and long life of the equipment.



High Grinding Efficiency and Low Energy Consumption

The slag vertical mill is equipped with a conical grinding roller device that offers low running resistance for the grinding roller, resulting in low energy consumption. The optimized grinding roll design can quickly and finely grind the slag into a fine powder, effectively improving the grinding efficiency, reducing grinding time, and increasing production efficiency. Compared to traditional tube mills, the slag vertical mill can save 45-60% of electrical energy, while material grinding can save 35-40%.



Easy maintenance

Replacing and maintaining wearing parts such as grinding discs and grinding rollers are relatively convenient and quick, reducing downtime and maintenance costs.



Comply with Environmental Protection Standards and Regulations

The slag vertical mill is equipped with an advanced exhaust gas treatment system. It can effectively control dust and exhaust gas emissions through reasonable airflow regulation and dust collection devices. In addition, the enclosed operating mode of the vertical mill can also reduce the impact of noise and vibration on the surrounding environment and staff.



Easy to operate and reduce costs

Shanghai YingYong slag vertical mill is easy to operate with the advanced automatic control system. The operator can monitor and adjust the key parameters through the intuitive interface to achieve precise control, and is able to complete the work task continuously and efficiently. In addition, the operating cost of the slag vertical mill is relatively low, saving manpower and energy resources.
