Dynamic steam inerting system for a ball tube mill
Abstract. Coal pulverizing system explosions during the last few years have pointed to the need of developing inerting systems for preventing such incidents. The greater use of western subbituminous coals (with their higher tendency for spontaneous ignition) is a contributing factor to the increased frequency of coal pulverizer explosions.

Dynamic load limits of a horizontal 4x4 or 6x6 beam?
2014-2-10 · An ~8ft long beam sits horizontally. Please just assume it is sufficiently supported and stabilized at each end. From the center of the beam hangs a ~200lb object such as a punching bag or a (living) human body. The object will not just hang statically, it will also swing. This rig is indoors only. I do not know whether the beam is a 4x4 or a 6x6.
