According to design standards, the surface of the permanent pool should return to the level of the bottom of the outlet control structure within 24 hours after the storm. sedimentation since a primary function of a stormwater pond is to trap debris and sediment, all stormwater ponds will accumulate sediment and will need to be dredged.
An ore fed to a rod mill has a bond work index of 14.0 kw hr t-1. the p80 of feed to the mill averages 2.50 centimetres and the p80 of the product from the mill is 0.104 millimetres. a) calculate the work required to grind the ore to the product size. b) calculate the reduction.
Ball mill design requires a bond work index, bwi, for ball mills at the correct passing size; sag mill design requires an appropriate sag test, for example, spi (chapter 5). flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( chapter 12.
Bond design information finally, a manufacturer may have a design in which it is desired to incorporate an adhesively bonded joint. to effectively design that joint, the designer must know which parameters are critical to the bond strengths achieved by a bonded joint and the effect that changing these parameters will.

Rod mills normally carry 35 to 65% rod charge by volume. the limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod.
Structural shapes – standard steel configurations produced by steel mills such as wide flanges, channels, angles, pipe, tubes, etc. structural steel – the structural elements that make up the frame that are essential to supporting the design loads, e.g. beams, columns, braces, plate, trusses, and fasteners. it does not include for example.
