Water Slag Grinding Mill Plant – 300,000 Tons Annual Production Line in Hebei

We provide a wide range of mills — including Raymond mill, trapezoidal mill, vertical mill, ultrafine mill, and ball mill, obtained ISO9001 international quality certification, EU CE certification, and Customs Union CU-TR certification. Suitable for processing minerals such as limestone, phosphate, quicklime, kaolin, talc, barite, bentonite, calcium carbonate, dolomite, coal, gypsum, clay, carbon black, slag, cement raw materials, cement clinker, and more.

The discharge range of these mills can be adjusted to meet specific processing needs, typically from 80-400 mesh, 600-3250 mesh, and can achieve the finest particle size of up to 6000 mesh(D50).

Water Slag Grinding Mill Plant – 300,000 Tons Annual Production Line in Hebei

In the heart of Hebei’s industrial zone, a state-of-the-art water slag grinding mill plant has been commissioned, boasting an impressive annual production capacity of 300,000 tons. This facility represents a significant leap forward in the processing of industrial by-products, transforming granulated blast furnace slag into valuable fine powder for cement and concrete production. The project underscores a commitment to both industrial efficiency and environmental sustainability.

The core of this operation relies on advanced milling technology to achieve the desired fineness and quality required by the market. After extensive evaluation, the engineering team selected equipment known for its high yield, energy efficiency, and minimal environmental footprint. The grinding process is critical, as it directly impacts the reactivity of the slag powder and its performance in final applications.

Technical Challenges and Solutions

Processing water slag presents unique challenges due to its abrasive nature and moisture content. Traditional ball mills often struggle with high energy consumption and significant wear on grinding media. This Hebei plant required a solution that could handle the material efficiently while keeping operational costs low and ensuring consistent product quality.

For this large-scale project, we highly recommend our LM Vertical Slag Mill. This mill is specifically designed for grinding industrial waste like slag. It integrates drying, grinding, powder selection, and conveying into a single unit, which drastically reduces the plant’s footprint—about 50% smaller than a traditional ball mill system. More importantly, its energy consumption is 30-40% lower, making it ideal for a 300,000-ton annual production target. The mill’s unique grinding device and high-performance wear-resistant materials ensure reliable, continuous operation with minimal maintenance downtime.

Why LM Vertical Slag Mill Excels in This Application

The LM Vertical Slag Mill operates on a negative-pressure air-sweep principle. The main motor drives the grinding table to rotate via a reducer. Hot air enters the mill to dry the slag simultaneously as it is fed onto the center of the table. Grinding rollers then crush the material. Its innovative design allows for precise control over fineness, and the absence of direct contact between rollers and the table minimizes iron contamination, ensuring a high-quality final product perfect for concrete additives.

Furthermore, the plant’s design incorporates our MW Ultrafine Grinding Mill for specific lines requiring ultra-fine powder production (325-2500 meshes). Although the primary focus is on slag, the MW mill offers incredible flexibility. It features higher yielding and lower energy consumption—40% higher capacity than jet mills and half the energy use of ball mills. Its cage-type powder selector, based on German technology, guarantees precise separation, and the absence of rolling bearings in the grinding chamber eliminates worries about seal failures or loose screws. This is complemented by an efficient pulse dust collector, making the entire process eco-friendly.

Operational Success and Environmental Compliance

The Hebei plant now operates smoothly, meeting its production goals while adhering to strict national environmental standards. The integration of these mills has resulted in a system that is not only highly efficient but also clean, with minimal dust emissions and noise pollution. The use of original spare parts and technical support from our company ensures worry-free, continuous operation, maximizing uptime and profitability for the client.

This project serves as a benchmark for modern slag processing facilities, demonstrating how the right technology can turn industrial waste into a valuable resource efficiently and sustainably.
