Jul 02, 2004 in the most common speed ratings, the nema designation of medium motors includes ratings of 1/2–500 hp for 2- and 4-pole machines, and up to 350 hp for 6-pole machines. temperature rise limits for large motors—i.e., those above medium motor.
Jul 10, 2014 selecting ac induction motors for cement plant applications (on photo:3,500 kw ball-mill drive for a cement plant in england via emz.de) although motors may appear to be the least complicated component in the specification of cement mill equipment, this article shall try to demonstrate that cement plant applications present an immense matrix of.
Jul 31, 2014 wm = wi ( 80p 10 - 80f 10 ) (1) where: wm - is mill specific motor output power (kwh/t), wi - is the bond ball mill work index (kwh/t), p80 - is sieve size passing 80% of the mill product ( m), f80 - is sieve size passing 80% of the mill feed ( m), the “efficiency factors” (rowland, 1975) modify equation 1 so that it caters for circuit.
Jun 25, 2011 (1) generally lrs is used for cement ball mill application. in some process plants lrs / fcma is also used. ball mill application is basically constant speed application. please note that, lrs / fcma are used with slip ring motor. in slip ring motors maintenance is big problem (wear and tear of brushes, brush assembly,.
Mar 31, 2008 cement mills are normally driven by electric motors. modern installations draw power of 2-10 mw. the power (in kw) required to turn a ball mill is approximated by: p = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and.
