TMEIC2 installed its first AC adjustablespeed motor drive system for a rolling mill main stand in 1980; by January 2004 TMEIC had installed AC adjustablespeed motor drive systems on more than 700 main mill stands, coilers and reels, constituting more than 2,400 MW of installed main drive power. 2. TMEIC: includes equipment supplied by Toshiba
Generation of Raymond Mill. In 1906, Grueber founded a machinery factory in the southern suburbs of Berlin. Using his patents obtained in the United States, he produced the first Maxecon mill and used it as the coal grinding equipment for the MOABIT power station. The grinding power can reach 5TPH.
The drive gear consists of the thrust bearing for the grinding table of the mill with the appertaining sup port, the planetary gear, and the separate bevel gear ing. The horizontally arranged electric motor drives via the cyclopalloid tooth system the sun gear of the planetary gear, which is connected via a tooth clutch coupling to the ...
Grinding mills are typically designed for long life (minimum 20 to 25 years). It is not uncommon to see grinding mills still operating today with an age of 23 times their original intended lives.
