This book offers the reader clear and accessible advice – whether seeking a standard screw feeder for a well-proven application, or designing from scratch for a new duty where no prior experience can be drawn upon for performance verification.
Screw feeders today play an increasingly important role in the drive towards improved quality, reduced costs, increased capacity, better working conditions, and flexibility in solids processing. Advances in control methods are being matched with improved predictability and reliability of the processes being controlled. The intensive and integrative nature of many production lines crucially depends upon each element working to its full design capability. Solid feeding operations comprise a key activity, renowned for operating difficulties out of all proportion to the cost of the equipment. This excellent book, by an acknowledged expert in the area, provides a valuable introduction to the subject together with guidance on the selection and application of a range of screw feeders.
