Figure 5 - Traditional Girth, pinion planetary gearbox kiln drive A recent installation for a 2500 MTD clinker plant uses a 2 pier support design kiln having a diameter of 13.6 ft and a length of 157 ft and is powered by a conventional girth gear and 2 x 335 hp DC drives. Not to be dismissed is the friction drive .
Step 1: Know the load characteristics. For line-operated motors, loads fall into three general categories: constant torque, torque that changes abruptly, and torque that change gradually over time.Bulk material conveyors, extruders, positive displacement pumps, and compressors without air unloaders run at relatively steady levels of torque.

Variable Speed Drives – an electrical energy saver In the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1. All these airflows

Cement Mill Drives - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Application of Electrical drives in Cement industry Includes function and requirements of: #Crusher Drives #Compressor Drives #Waste Gas Fan Drives #Rotary Kiln Drives #Cement Mill Drives
Center drive and side drive are two common drive modes for a ball mill. Center drive grinding mill means the motor shaft extends along the axis of mill body while side drive has a motor located on the side of the mill and torque is transmitted via the large girth gear which is bolted on the flange of the mill body.. Materials are fed into the mill at a fixed flow rate along the shaft-less ...

The type of drive chosen to run the industrial motor can add some positional awareness. An encoder can be added to the motor if the application requires it, and a drive can be specified to use the encoder feedback. This setup can provide servo-like speed as a result. 3. Is position control required for the application?
