Guide to the Design, Selection, and Application of Screw Feeders
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.

promotion of bulk storage and handling interests, perceived the
need to make available a practical guide to the design, selection,
and application of screw feeders. the author, Lyn Bates, as
an international renowned expert in this field, was commissioned to
prepare this user Guide.
As Managing Director of Ajax Equipment Limited, a company that
specializes in screw-type equipment for solids handling, he enjoys
a 'hands-on' attitude to powder handling problems. He has
introduced various design innovations and patents in the field and
designed various instruments for measuring flow-related powder
properties. As a member and past chairman of the Institution of
Mechanical Engineers Bulk Materials Handling Committee, he produced
a 'Guide to the Specification of Bulk Solids for Storage and
Handling Applications'. An active member of the European Federation
of chemical Engineers Working Party on the Mechanics of Particulate
Solids, and sitting on various BSI and other technical committees,
he is dedicated to promoting education in this specialized section
of engineering.
Lyn Bates has written many technical papers and
publications on aspects of bulk solids handling. This book
complements related publications by the BMHB, which include the
author's earlier book 'A User Guide to Segregation', as well as
'User Gide to Particle Attrition in Mechanical Handling Equipment',
prepared by a working party chaired by Lyn Bates.
