nickel slag vertical roller mill with rotating grinding disk

Nickel Slag Vertical Roller Mill Overview

Nickel Slag Vertical Roller Mill is a specialized equipment for grinding nickel slag, slag and other similar materials. It utilizes the vertical roller mill technology, which not only improves the grinding efficiency, but also has a strong drying capacity through the special design of grinding discs and rollers. The innovative design of nickel slag vertical roller mill makes it highly integrated in the process of grinding, classifying and drying, which simplifies the process flow, saves floor space and reduces the production cost.

Working Principle of Nickel Slag Vertical Roller Mill

Based on the joint action of grinding disk, grinding roller and hot air flow. The material enters the center of the grinding disk through the downcomer tube, and under the action of centrifugal force, the material is evenly distributed outward and forms a certain thickness of material bed. At the same time, the grinding rolls pulverize the material through the pressing action. Driven by the continuous centrifugal force, the material moves towards the outer edge of the grinding disk, which is brought up by the high-speed airflow through the wind ring and rises into the separator. At this time, the material and the hot airflow undergo sufficient heat exchange, and the moisture is rapidly evaporated. Adjusted by the separator, the fine powder in the material that meets the requirements is separated out and directly used as the finished product, while the larger particles return to the mill to continue grinding. The exhaust gas is discharged after the fan muffles the sound. For the large particles that are difficult to be ground, they will enter the external circulation system through the slag spit, and return to the mill for grinding after iron removal.

Features of Nickel Slag Vertical Roller Mill

1. Integrated design: Nickel slag vertical roller mill integrates the functions of grinding, drying, grading, etc., simplifying the process flow and reducing the equipment footprint.
2. Significant energy saving effect: Compared with the traditional ball mill, nickel slag vertical roller mill system power consumption is significantly reduced, energy saving effect is obvious.
3. High-efficiency grinding and drying: Through the optimization of airflow and heat exchange system, it can complete the grinding and drying at the same time, adapting to the processing of different humidity materials.
4. Adjustable fineness of discharged material: By adjusting the setting of powder selector, the particle size and specific surface area of the product can be precisely controlled to meet the needs of different products.
5. High stability and reliability: The equipment has simple structure, stable operation, low failure rate and easy maintenance.

Advantages of Nickel Slag Vertical Roller Mill

1. Low energy consumption: Nickel slag vertical roller mill has a low system power consumption of no more than 43 degrees per hour, saving 30%-40% of the power than the traditional ball mill, which significantly reduces the production cost.
2. Stable product quality: The specific surface area of nickel slag micropowder can reach 4200 to 4500 square centimeters per gram, the product quality is stable, the particle size is uniform, suitable for further processing or application.
3. Simple structure, small footprint: The equipment has a simple design, small footprint, reducing the construction cost of the production line and space requirements.
4. High return on investment: Due to the gradual increase in demand for nickel slag micropowder in the market, investment in nickel slag milling production line can get a high rate of return on investment, usually in 1 to 2 years can recover the cost.
5. Environmental protection and high efficiency: The sealing of the equipment is good, dust pollution is small, in line with modern environmental protection requirements, while reducing emissions, in line with the needs of green production.
