Assume you have plenty of black powder already prepared. When budgeting, make sure to keep in mind cost, shipping and of course, safety.
DetailsBall mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.
Detailsal., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine grinding with the same ore and size distribution. Despite these developments, the tumbling mills are continuing to be used in fine and ultrafine grinding applications. The main reason for this, as communicated at the Canadian Mineral Processors
