Customer: Cement plant From an African cement plant Menzel received the order to supply a interchangeable motor to the existing main mill drive. In fact the customer bought already another interchangeable Menzel motor; he confided these complex tasks to the Menzel specialists.
#0183;#32;7. Slip Ring Induction Motor. It has high starting torque and large overload capacity. The speed of slip ring induction motor can be changed up to 50% of its normal speed. Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, presses, line shafts, elevators and compressors etc.
To make cement, the clinker must first be cooled. Prior to being crushed in the cement mill, the gypsum produced in the kiln is separated from the main product stream. The output from the cement mill may be blended with other constituents to meet certain specifications depending on the end use. The packaged product is then shipped to the consumers.
