Material handling automatic

Automatic discharging suspended magnets can be operated transversely (Fig. 2) or parallel to conveyor flow (Fig. 3b and 3c). Because the tramp iron must be attracted from a buried location and turned 90° from the movement of the conveyor belt, a larger and stronger magnet is required for a transverse installation. In some instances, the material handling layout, or desired operation location, dictates the use of the transversely mounted magnet. 

In the last 20-30 years material handling in mill rooms as well as the mixing process is highly automated. Also, downstream equipment runs in an automatic control mode. 

When a system is more complex and there are more potential sources of dynamic variations, a more complicated control is required. Particularly in automatic systems where human operators are replaced by machines and computers, a thorough design of control responsibilities and procedures is necessary. Control activities include automatic control of individual machines, material handling, equipment, manufacturing processes, and production systems, as well as control of operations, inventory, quality, labor performance, and cost. Careful design of correct and adequate controls that continually identify and trace variations and disturbances, evaluate alternative responses, and result in timely and appropriate actions is therefore vital to the successful operation of a system.
