A steel manufacturer in Shandong uses blast furnace slag from their ironmaking process to produce building materials like cement and concrete. Back in 2007, they visited Zhengyuan to explore ultra-fine grinding solutions and decided to purchase an LHM ultra-fine ball mill classification line. The processing system reduced slag particle size to D97=10μm, enhancing both product quality and added value. With growing demand in the high-speed rail and construction sectors, they returned in 2012 and 2019 to purchase two more lines to support large-scale ultra-fine slag processing.

A chemical company in Handan specializing in tire pyrolysis carbon black production utilizes two of our LHJ ultra-fine mechanical mills. These milling machines allow the company to produce products with particle sizes ranging from 300 to 2500 mesh. The impact milling equipment these clients purchased have operated reliably, providing a stable production environment and ensuring consistent product quality.
