Ball Mill Unloading

Dense Phase pneumatic conveying offers a conveying solution for ball mill unloading that is fully enclosed (dust free), and conveys material at low velocities with minimal moving parts. A Ball Mill is a large rotating cylinder filled with heavy grinding balls used to pulverize a variety of materials into fine powders. Material exiting the discharge of a ball mill is often extremely fine and aerated, so, mechanical methods of conveying (belt, screw conveyors, etc.) can leak dust and material into the area surrounding the ball mill potentially causing hazardous or harmful conditions. A dust free conveying method (Dense Phase Pneumatic Conveying) is preferred. Also, because the material pulverized in ball mills is often abrasive the low material velocity and minimal moving parts within a Dense Phase Pneumatic Conveying system insures system downtime and maintenance costs are kept low.

JDB Ball Mill Unloading Solutions

At JDB Dense Flow our Ball Mill Unloading systems feature a fully enclosed (dust free) dense phase pneumatic conveying system, with low average material velocities and minimal moving parts throughout the system (in most cases only one moving part, the Dense Flow Cone Valve Assembly). Each ball mill unloading system we design is custom tailored to provide a Dense Phase conveying system that maximizes Ball Mill unloading rates and minimizes wasted energy. Our advanced air delivery system closely monitors pressures during a material convey cycle, and adds air only when necessary to maintain the systems optimal conveying pressure. This insures that the material is conveyed with minimal wasted energy, at the lowest possible velocity resulting in pipeline components lasting significantly longer. The Advanced Air Delivery System is monitored and controlled through an electric panel that features a color touch screen display. From the display operators can monitor the conveying system, as well as make changes if necessary.
