Jun 10, 2021 The morphology of Fe 2 O 3 powders was controllable during ball milling, so it was used as an additive for mechanical alloying [57, 58]. Similarly, in the liquid metal forming process, oxides with thermal stability or melting points lower than Y 2 O 3 can be added into the liquid steel containing Y as oxygen carriers. Meanwhile, the wettability ...
Aug 07, 2009 A very basic overview, but the advantage of wound rotor slip ring motor is that, through a LRS u can vary the resistance of the rotor. The advantages are 1. able to manipulate the torque speed curve, allowing u start with a much higher torque. Wound motors are suitable for application with heavy starting duties such as ball/sag mills, crushers etc.
Sep 02, 2020 The ball mill will usually work for a long time without any damage unless the depth of lining wear is enough to have a serious impact on safe operation and efficiency of a ball mill. If depth of lining wear is serious, you should replace the ball mill liner as soon as possible.

Jul 31, 2003 The motor drives a cement ball mill, and the operator is blaming the starter but I think that if it is not accelerating as it used to then the load has increased. Any thoughts? Also the starter used soda ash (sodium carbonate) to modify the conductivity fo the water, does any one know what the chemistry of the liquid should be?
Although liquid resistance starting is a mature technology, it is being applied to more demanding big mill starting applications today than ever before. Starting problems can result in the application of high torque transients to the mill gearbox, pinion gear and girth gear with damaging results.
