Losses from Air-Cleaning Devices - In addition to pressure losses in the ductwork, the losses in the dust collector must also be known. Although the pressure drop for dust collectors varies widely, data are usually available from manufacturers. lV'ore information on dust collectors can be obtained from chapter 4. Points to Note in Ductwork Design/Layout - To minimize pressure losses, the Industrial Ventilation lV'anual recommends the following guidelines for ductwork design: 47 48 Dust Control Handbook • • All branches should enter the main at a 30 0 angle; wherever possible, the velocity should match that of the incoming gas stream.
In its basic form, a grinding mill consists of a horizontal, slow-speed, rotating cylindrical drum. Rod, pebble, and ball mills are the most common types of grinding mills used in minerals processing operations.
