Kiln motor selection requirements

Article source:

The motor-driven rotary kiln require speed, due to the large kiln change, we must ensure a 1:3 speed range above. DC motors are commonly used in the rotary kiln dryer, wound rotor induction motor, electromagnetic induction motor, variable speed motor commutator, squirrel cage induction motors and multi-speed squirrel cage induction motors. Kiln commonly used DC motors, DC motors wide speed range, enabling smooth stepless speed, smooth start, good starting performance, is conducive to automation. Power DC motors, AC motors past DC generator driven by an electric generator power, but Rotating Machinery, maintenance workload and other shortcomings, the use of silicon controlled rectifier control devices in recent years to overcome these shortcomings, speed range 1:10 or more, start fast, fully meet the production needs.
