Get PriceNov 11, 2008· Re: Kiln Torque. Hi , Good morning . A torque is a measure of the tendecy of a force to rotate an abject about an axis. If force is a push or pull action ,torque is similar force that tends to bring a twist . Kiln torque is produced by the main drive .Torque control in kiln can be achieved by controlling the motor parameters. Regards, Kesav. Reply
