Inomax AC VFD solution for Cement plant rotary kiln

The Rotary Kiln is very important and critical equipment in cement manufacturing process. At the same time it poses many challengesRotating a very large and heavy steel cylinder with material at low speed requires high torque. Also it consumes large amount of energy in theform of fuel and electricity among other equipment within cement plant.

The speed control of rotary kiln is one of the critical factors for utilizing its production capacity, ensuring product quality, optimising fueconsumption, maintaining low running cost and meeting environmental standard. Precise speed control keeps kiln turning continuous andefficient.

Inomax offers a wide selection low voltage AC, medium voltage AC and DC drives which can accurately synchronize motor speed and torque. Our low voltage variable speed drives have Direct Torque Control (DTC) function which provides fast and accurate control for speed and torque event at zero speed. DTC doesn't need additional sensors to operate. Our global service network can provide skilled service quickly when needed.

Torque control, Accuracy. Efficiency. Everything counts with high quality clinker.
