Homework and Lab

Materials Handling: Class Objectives Students should be able to: Explain the uses of several methods to convey materials handling Identify miscellaneous and less-common methods of conveying materials

Bulk or Mass conveyors Paddles of various shapes attached to a chain at equal distance and housed in a rectangular or circular housing

Inclined and vertical conveyors

Belt Conveyors Carry different types of materials Easy-flowing to sticky Handle material gently Variable speeds, capacities and widths Angle of slope generally <30°for smooth belts Cleated or grooved belts can handle greater slope

Types of belt conveyors Two main types Flat Troughed

Belt conveyor capacity Capacity varies with belt speed, width, and uniformity of loading

Flight Conveyors Consist of chain-carried scrapers for flat conveying or formed buckets for vertical work Use of single-chain flight conveyors and heavy duty conveyors with two or more chains

Belted Chain Conveyors Type of flight conveyor Use and function is similar to belt conveyors Can be used on greater slopes (elevating materials to place in pile)
