In this paper, a novel method of wet ball mill load identification based on CEEMDAN, RCMDE and SRNN is proposed. Firstly, CEEMDAN-RCMDE is used to extract the load features of the ball mill. Then, taking the advantage of SRNN's fast training speed and strong generalization ability, a mill load identification model based on SRNN is …
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Based on the media, two types of ball milling, namely dry and wet, are classified. As the name suggests, wet milling disperses the material in liquid media to form a slurry, while dry milling relies on particle contact. Although dry and wet milling can both be adapted for various materials, certain restrictions do apply. ...
The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that …
Wet Ball Mill. Feeding size: ≤25mm. Capacity: 0.65-615t/h. Motor power: 18.5-4500kW. Applications: It can deal with metal and non-metal ores, including gold, silver, copper, phosphate, iron, etc. The ore that needs to be separated and the material that will not affect the quality of the final product when encountering water.
Dry ball milling requires less energy than wet ball milling but has a lower throughput. Wet ball milling requires more energy than dry ball milling but also has higher throughput. . Dry ball milling is more efficient for materials that don't require very fine particles or have a low tendency to group together.
