A mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance interms of system availability and output, however power consumption was on higher side. System Description Mill Rated capacity 150 t/h OPC at
Comet LA 400 Series. Single Sprocket Centrifugal Clutch. Use the LA 400 series Comet Centrifugal Clutch for up to 8 hp 4 cycle engines. Straight centrifugal rotor action provides slipping range into smooth, nonaggressive engagement with approximate engagement of 2000 rpms.
To improve the efficiency of the drives used for the large mills found in the cement industry, Voith Turbo amp; Co. KG has developed a powerful and slipfree coupling combination rated at 10 MW. The 1210 TPLSYN coupling is also suitable for other drives with constant input speed, such as extruders, turbo compressors, axial fans with adjustable guide fans.
Ball mill is the most widely used kind of grinding equipment. Zenith Ball mills are widely used in various types of ores'' benefication, electricity, cement and chemical industries. With high comminution ratio,it can carry out dry or wet pulverizing and can meet demand for sustainable largescale production.
Drives for Mills amp; Separators Drives for ID Fans Drives for the Finish Mill Variable Frequency Drives in the Cement Industry Controlling fan ow by adjusting speed avoids wasting energy in adjustable dampers and louvers. When large ows are involved and the motor energy consumption is signi cant, varying the speed is the answer. With large
