Sugar Mill Process: The Sugar Mill Process the crystals are separated from the syrup by means of a centrifuge. The separation is accomplished by the centrifugal forces set up. The centrifuge is started to a speed of around 200 rpm at which the charging of syrup takes place. During charging the motor is disconnected from …
Cement Mill Process: The Cement Mill Process has different Stages in Cement Production and they are The raw materials of Cement Mill Process are lime and silica. Alumina and ferric oxide are used as fluxing agents. Collection of raw materials such as lime stone. This is transported to the mill site and crushed there if …
Cranes and Hoist Drives: The Requirements of the Cranes and Hoist Drives are The motion of the crane hook is in all three dimensions. In crane drives, the acceleration and retardation must be uniform. This is more important than the speed control. For exact positioning of the load creep speeds must be possible. When the …
Types of Steel Rolling Mills: Types of Steel Rolling Mills are either hot rolled or cold rolled. These may be either reversing type or continuous type. The motors used for reversing mills need operation in both the directions of rotation. A four quadrant operation of the motor may be required. In the continuous type the …
Control of AC Motors Torque Control: From the foregoing discussion for Control of AC Motors Torque Control it is clear that the motors used for textile applications must have high starting torque torque control providing uniform acceleration so that the breakage of the yarn is minimum and the quality of the product is improved. The production …
Drive Considerations for Textile Industry: There are several processes involved by the dine the finished cloth comes out of a mill from its basic raw material, cotton picked up from the fields. The requirements of the motors are different for different processes. These mainly depend on the nature of the process. The several stages in …
Applications of Electric Drives: The industrial Applications of Electric Drives are numerous. To arrive at a particular motor of suitable size for a given application, a knowledge of the following is very much necessary: The torque-speed curve of the industrial load is required. This fixes up the type of motor required to drive the load. …
