Understanding Rolling Process in Long Product Rolling Mill ...

Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of tons/hour.

How Wall Friction Affects Hopper Angles | Powder/Bulk Solids

How Wall Friction Affects Hopper Angles. A switch back and forth between mass flow and funnel flow can cause severe bin vibrations and other problems. This region represents a margin of safety to minimize the above effects. Always remember, Jenike's charts give the hopper angles in degrees from vertical.

Resolution of Forces, Friction, and the ground reaction vector

Friction. So far we've looked at purely vertical forces: the force on the falling apple or the ground reaction on the body while standing still. To move the box you must overcome the friction force between the box and the ground. It acts in the opposite direction to the direction you're pulling.
