Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directedGrinding Mill an overview ScienceDirect Topics

Ball Mill & Discharge Trommel. Grate Discharge Ball Mill . For closed grinding circuits producing typical ball mill products, indirect and direct on-line measurements of the product size are available. The indirect means are those which assume that the product size is relatively constant when the feed condition to the The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.

(PDF) Combined DEM and SPH simulation of ball
In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods. ThenSometimes, you solve scatting by charging the ball mill correctly (I saw cases where the mill was up to 15% under power). Other times, you need to enlarge the ball size diameter ie: using a 75 mm ball Scats production in overflow ball mill 911

Combined DEM and SPH simulation of ball milling
A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both The trunnion magnet consists of a barrel or “blind trommel” that is mechanically attached to the trunnion or discharge of a ball mill. The barrel rotates around a fixed assembly of ferrite and rare-earth magnets, positioned on the outside of the barrel. The stationary magnetic assembly, approximately 28 in. long, covers an arc of about 210Magnetic Separation Technology Can Improve Grinding Circuit Efficiency
