Guide to Design, Selection, and Application of Screw Feeders was initiated by the Department of Trade and Industry under the auspices of the British Materials Handling Board, who perceived a very real need for a practical guide to designing, selecting, and using screw feeders. It 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. Solids feeding operations are a key industrial activity, but are renowned for operating difficulties that are quite unrelated to the capital cost of the equipment. Accurate, reliable performance of gravimetric feeders can both improve the quality and consistency of a product through close control of ingredient materials and offer impressive savings through reduction of 'give-away' or 'over-delivery' of product of filling machines. * Clear and well structured * Has international appeal * Practical - drawn from experience * Well illustrated * Offers solutions to real problems This Guide offers invaluable information to industrial companies that process and handle bulk materials and to equipment manufacturers - including design and process engineers, plant and production managers, and maintenance engineers who are seeking to optimize performance of production plant.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
The British Materials Handling Board, following their long-term 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.
