How to Calculate Floor Load Capacity | Hunker

The dead load on a floor is determined by the materials used in the floor's construction. A typical wood-frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot; if there's wall-board covered ceiling suspended from the underside of that floor, the dead load increases to about 10 pounds per square foot.


Mill Charge - an overview | ScienceDirect Topics

Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further. However, close packing of the charge rarely occurs and an operating bed ...

Optimization of mill performance by using - SciELO

To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.
