Crushed materials are sent to the ultra-fine mill for grinding. Inside the mill, the grinding roller crushes and grinds the material against the grinding ring. Fine particles are collected by cyclone collectors, aided by air separators and blowers, while coarse material is reclaimed for further grinding. Dust collectors control emissions and remove excess dust to prevent clogs.
The equipment boasts a compact design, ensuring 24/7 operation with minimal energy consumption.
Utilizes high-pressure spring technology for improved output, delivering finer and more consistent grinding results.
Features a turbo-type air separator and variable frequency motor for precise fine powder classification, resulting in a uniform and impurity-free finished product.
Incorporates wear-resistant alloy materials for easy maintenance of grinding components, along with advanced seals that extend lubrication cycles, reduce noise, and effectively eliminate dust.
We collaborate with clients globally to deliver top-notch mineral processing equipment and tailored solutions, aiming to optimize plant efficiency and reduce operating costs.
