Changsha Wanrong Powder Equipment Technology Co., Ltd. is a specialized manufacturer of ultrafine grinding machines and powder‑modifying equipment. Its core products include the cell‑grinding wet‑process ultrafine grinder and the honeycomb‑grinder continuous powder‑modifying machine.

In the mineral processing of metallic ores, energy consumption and grinding media wear during the fine‑grinding stage are key factors influencing production costs. Conventional ball mills exhibit high energy consumption and substantial media loss in the fine‑grinding phase, imposing significant cost pressures on mining enterprises.

The multi‑axis mill employs a grinding technology that combines gravity and fluidization, leveraging the rotational kinetic energy of multi‑stage agitator discs to drive the grinding media and slurry into vortex‑like motion. Under shear and compressive forces, the material particles undergo fine grinding. Compared with conventional ball mills, the multi‑axis mill reduces energy consumption in the fine‑grinding stage and also helps to control media wear.

In a certain metal ore‑beneficiation project, after employing a multi‑axis mill for fine grinding, both the grade and recovery of the iron concentrate improved, while specific energy consumption and media consumption decreased compared with the conventional process. The equipment is arranged vertically, occupying a small footprint and requiring simple foundation construction, making it well suited for the retrofitting and upgrading of existing concentrators.

The company offers material testing and process validation services, recommends optimal equipment configurations and process parameters based on ore characteristics, and helps mineral processing enterprises reduce costs and improve efficiency.
