The energy-saving wet grate ball mill is a high-efficiency grinding machine that represents a technological innovation based on the traditional grate ball mill. It is designed specifically for wet grinding processes. Its core innovation lies in the use of rolling bearings instead of traditional sliding bearings, reducing friction by over 30%. The corrugated liner design increases the contact area between the steel balls and the material, significantly improving grinding efficiency while also reducing energy consumption.

The grate structure, which provides forced discharge, effectively prevents overgrinding and increases throughput by 15-20% compared to conventional ball mills. It is particularly suitable for coarse grinding of metallic ores such as gold and copper. The modular design of the drum, equipped with a hydraulic jacking device and an oil mist lubrication system, reduces maintenance costs by 25%, making it the preferred equipment for energy-saving retrofits in modern mineral processing plants. The structural design of the energy-saving wet grate ball mill fully embodies the combination of high efficiency and innovation. The drum utilizes a composite structure of high-manganese steel liner and wear-resistant rubber liner, extending service life and reducing noise.

The transmission system utilizes an external gear drive, coupled with synchronous control by dual motors, ensuring a stable drum speed within the optimal operating range of 18-22 rpm. The grate plates at the discharge end feature a radial arrangement, with inclined apertures accelerating slurry discharge. A combination of a central liner and a dustpan-type liner forms eight fan-shaped chambers, utilizing centrifugal force to achieve a step-by-step lifting of the slurry. The feeding system utilizes a combined drum and volute feeder, with spiral blades within the hollow shaft to protect the shaft and ensure uniform material delivery to the grinding chamber.

The energy-saving wet grate ball mill, with its superior energy-saving performance and efficient grinding capacity, has become an indispensable core equipment in modern mineral processing plants. Innovative designs such as rolling bearings, corrugated liners, and an intelligent lubrication system significantly reduce energy consumption and maintenance costs while increasing throughput and grinding efficiency. Its forced discharge structure and modular design further ensure stable operation and ease of maintenance. Under the current industry trend of energy conservation and emission reduction, energy-saving wet grate ball mills not only bring significant economic benefits to mineral processing companies, but also provide important technical support for promoting green mine construction.
