Abstract

Control system has temp. detector positioned to monitor rotary drum drier outlet temp. and a switching mechanism connected to this so that heater unit is cut out when temp. reaches a chosen max value, the drum drive being out only when temp. falls to a second value after a suitable cooling period. System is cheaper than those using costly sequence times to control process.
