Amid rising fuel costs, Qibin Group took the lead in launching an oil-to-coke conversion project, replacing traditional heavy oil with high-calorific, cost-effective petroleum coke powder. The success of this initiative depends heavily on a stable and efficient powder preparation system.

With its outstanding performance and integrated solution capabilities, Liming Heavy Industry's MTW European-type Grinding Mill successfully secured the bid, becoming the core equipment supplier for six subsidiaries of Qibin Group.

The MTW grinding mill delivers strong support for the project through multiple advantages. It ensures high efficiency and stable operation, utilizing patented technologies and a bevel gear integral transmission system to provide powerful drive, smooth performance, and low energy consumption—fully meeting the continuous production demands of glass kilns.

Its unique curved air duct design effectively prevents material blockage, while the variable frequency cage-type classifier enables precise control of final product fineness. In addition, the thin oil lubrication system significantly extends maintenance intervals and reduces operating costs, enhancing overall economic performance.

Designed with environmental protection in mind, the entire system operates under negative pressure and is equipped with a high-efficiency pulse dust collector, ensuring dust-free operation and full compliance with environmental standards.

Over the past 12 years, 15 MTW grinding mills from Liming Heavy Industry have operated reliably, providing a consistent supply of qualified fuel for Qibin's glass furnaces. This long-term performance not only guarantees the success of the oil-to-coke project but also highlights Liming Heavy Industry's strong capabilities in delivering large-scale, efficient grinding solutions.
