If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a …
is vital for the health of your mill. If not controlled, fluctuations can shorten the life of key components. Outotec solution: A trunnion bearing lubrication system retrofit featuring: • Custom-sized reservoir • Filtration system and heat exchanger • Temperature, flow, and pressure instrumentation Grinding retrofits Trunnion bearing
Factors affecting load-bearing Capability of Trunnions. The load-carrying capability of a trunnion mainly depends on the following factors: Parent pipe and trunnion/dummy pipe diameter: With an increase in pipe size the load-carrying capacity increases.; Parent pipe thickness: With an increase in pipe thickness the load-carrying capability increases. ...

Explanation: Pitch: Designated by "X P".For example, M8 X 0.75 means an 8 mm (0.315″) thread with a pitch of 0.75 mm (0.03″ or 34 TPI).If the "X P" is omitted, the pitch is defined by the Coase Pitch Series according to ISO-261. Number of starts: Designated by "Ph".For example, M8 X Ph2.25P0.75.In this case, 2.25 mm is the lead, and 0.75 mm is the pitch.
