steel slag ball mill

Product Introduction

Steel slag ball mills are primarily used for slag separation and grinding. Their development meets the requirements of steel manufacturers for processing steel slag powder, ensuring optimal utilization and avoiding resource waste. DMG Heavy Machinery, a manufacturer of steel slag ball mills, prioritizes product quality, relies on technological innovation, and optimizes product structure. Steel slag ball mills are widely used in industries such as mud, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics, for dry or wet grinding of various ores and other grindable materials. Steel slag is an industrial waste, strictly speaking, a type of industrial waste. Improper utilization of this waste inevitably causes environmental pollution. The equipment used to process this waste is the steel slag ball mill. DMG Heavy Machinery utilizes both German and domestically developed technology, making it a highly versatile grinding equipment.

Operating Principle

A steel slag ball mill consists of a feed section, a discharge section, a rotary section, and a transmission section (reducer, small transmission gear, motor, and electronic control). The hollow shaft is made of cast steel with a removable inner lining. The rotating gear is made of cast gear hobbing and the cylinder is inlaid with a wear-resistant lining, which makes it have good wear resistance. This machine runs smoothly and reliably and can operate continuously for a long time.

A slag ball mill typically has two grinding chambers. The first chamber is often lined with stepped or corrugated liners. Steel balls of various sizes are loaded inside. The corrugated and stepped liners provide a strong lifting force for the balls, allowing them to reach a greater height. As they fall, they effectively crush the slag, completing the coarse grinding of the slag in the first chamber. The ground material in the first chamber passes through a single-layer partition into the second chamber. The second chamber is often lined with flat liners, which provide a weak lifting force for the balls. Due to the greater relative motion between the balls and the liners, the second chamber provides a stronger grinding force for the slag, completing the fine grinding process. The finely ground slag in the second chamber is discharged through a discharge grate, completing the slag grinding process.

Product Advantages

1. Advanced and Wear-Resistant Components

Advanced wear-resistant materials ensure long component life.

2. High Product Utilization Rate

Grinded steel slag can be used to recover valuable metals and produce cement, achieving zero steelmaking waste discharge, reducing environmental pollution and achieving comprehensive resource utilization.

3. Advanced Processing Technology

The liner of this equipment undergoes an advanced dual-medium quenching process, which allows it to withstand significant impact forces and minimize deformation and wear, ensuring equipment quality.

4. Convenient and Quick Maintenance

The steel slag ball mill uses thin oil lubrication instead of grease, preventing poor lubrication due to oil starvation. This reduces the friction coefficient of bearings and other components, reduces maintenance and inspection frequency, and facilitates convenient and quick operation.

5. The steel slag ball mill processes steel slag and primary slag steel as raw materials, utilizing a closed-loop production process. Through screening, negative pressure ball milling, dry magnetic separation, and wind classification, four high-efficiency, high-quality, and high-value-added products are obtained: high-quality scrap steel with an iron content exceeding 90% suitable for steelmaking; high-grade iron ore concentrate for ironmaking; fine steel slag powder used as a highly active admixture for cement and concrete; and aggregate for steel slag asphalt concrete surface layer for high-grade highway pavement. This truly achieves zero steel slag emissions, completely eliminating the environmental impact of steel slag.
