Conveyors


Book Description

This is probably the first book in 40 years to comprehensively discuss conveyors, a topic that seems mundane until the need arises to move material from point A to point B without manual intervention. This book gives industrial designers, engineers, and operations managers key information for determining which type of conveyor to purchase and how to use it to meet their transport needs. It discusses requirements for specific products or materials and environmental factors, including extreme temperatures. Each chapter covers a specific type of conveyor including chain, belt, and gravity varieties, highlighting the primary features such as load capacity and rate and operation.
