  How to Speed up the Curing Process of Concrete

  Use relatively warm water in the concrete mix to induce reactions. Warm water increases the speed of chemical reactions in concrete. However one should be aware that overly hot water can have a damaging effect on concrete. Blend calcium chloride with wet concrete mix before placement to increase the speed of cement hydration.

  Mill Critical Speed Determination

  The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface. This is the rotational speed where balls will not fall away from the mill s shell. Result #1 This mill would need to spin at RPM to be at 100 critical speed. Result #2 This mill s
