Opis

From Powder to Bulk provides the opportunity to explore the latest key powder and bulk solids handling issues and technologies. The international flavour of the papers in this volume provides a forum to facilitate the dissemination of knowledge - to learn from experts in research, academia, and industry. Significant technical and operational advances in dry processing technology are described. Topics covered are as follows:

• Characterization
• Silos
• Control and instrumentation
• Pneumatic and mechanical conveying
• Segregation and screening
• Feeders

From Powder to Bulk will be valuable reading to senior management, engineers, and technical managers from industry, universitites, research organizations, equipment suppliers, and development and consulting organizations. This volume will be of practical interest to all those in the design, specification, operation, and maintenance of powder and bulk materials handling and storage plant.
