بیشترFirst, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.

بیشترThe entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner. The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting. The drum also provides a convenient method of adding grinding balls to a ball mill. The drum is generally lined with Manganese Steel.

بیشترYes, but our mills are so simple to operate that very few people bother. But, the control system in a loss-in-weight feeder may be used to trigger a shut down of the mill in case there is no feed, and a pressure sensor could be installed to shut down the mill if there is not enough air. These are the key parameters to monitor.
