Size Reduction of Divided Solids

Size Reduction of Divided Solids, part of the Industrial Equipment for Chemical Engineering set, presents a practical guide for choosing devices and flow and rate parameters in the size reduction of divided solids. The size reducing principles are presented, with their application to plant products used as examples, also taking into account the influences of heat and humidity.

The author also provides the methods needed for understanding the equipment used in applied thermodynamics to encourage students and engineers to self build the programs they need. Chapters are complemented with appendices that provide additional information and associated references.

• Includes the empirical laws governing overflow and underflow of a bulk solid
• Provides characteristics of bulk solids
• Presents a practical guide for choosing devices and flow and rate parameters in the size reduction of divided solids

Students and engineers in Process and Chemical Engineering; those working in the Chemical, Food, Pharmaceutical and Oil industries
