2023715 · Abstract To reduce the ore loss and dilution caused by blast-induced rock movement in open-pit bench blasting, a dividing open-pit blast (DOPB) method was theoretically analyzed, numerically simulated and applied to the Husab Uranium Mine, Namibia. First, a general open-pit bench blasting process was analyzed, and the DOPB …
view moreCogging force produced in a tubular permanent magnet machines due to the interaction between the permanent magnets and the stator teeth causes an undesired vibration and noise. In applications such as robotics there is a need for precise position control and for this purpose force pulsation should be minimized. This paper presents a new method for …

Water as a medium is an important factor in improving the differential movement between various particles during gravity separation and eventually sorting different particles [ 2 ]. When water is removed, and air plays ...
