general the bigger the mill diameter the lower are the mill operating and critical speeds. Thus for larger mills the number of poles will increase. As a result the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

Chat MoreA ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 3050 of the mill volume and its size depends on the feed and mill size.
Chat MoreI am involved in design of a HAWT. I would like to know the influence of number of blades in a wind turbine and its power output. Do share if you guys have an answer.
Chat MoreAt 33 mph most large turbines generate their rated power capacity and at 45 mph (20 meters per second) most large turbines shut down. There are a number of safety systems that can turn off a turbine if wind speeds threaten the structure including a remarkably simple vibration sensor used in some turbines that basically consists of a metal ball attached to a chain poised on a tiny pedestal.
Chat MoreA mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water ().
