It includes information on design and specification, preparing the reader to select and correctly size equipment.
As a design or project engineer working with vendors to make final equipment selection, this work provides the readers with the full facts before they start talking to product vendors.
In an environment of industry consolidation, the handbook allows you to track suppliers old and new, providing a basis on which users can find the new relevant company for the parts/service he/she wishes to purchase.
Once an equipment purchase is made, the user needs to be made aware of how to optimally operate decanters. The Decanter Centrifuge Handbook covers relevant (process) operating issues such as instrumentation and control and the use of flocculents.
Decanter development Manufacturers: who entered the markeplace, who left, who owns whom, specialities of major suppliers
Trends in technology
Basic construction: vertical/horizontal, concurrent/countercurrent, leading/trailing conveyor, design limitation, natural frequency versus L/D and design
Materials of construction: maximum bowl speed versus bowl diameter, materials of construction
Basic components: bowl, conveyor, casing, drive, backdrive, gearbox, frame and mounting, inlets and outlets, bearings and seals
Variants: bowl diameter, clarifying length, beach angle, scolling aids: liners and grooving, conveyor leads, conveyor pitch, flight profile, cant and rake, flow: axial helical and vane assisted, baffle designs, feed zone design and position, polymer inlets, gearbox designs and alternatives, cake discharge, brakes, weat inserts, tiles, noise abatement features, surface finishes
