The example below is concerned with a ball mill made of an asynchronous motor, a gearbox speed reducer, a quill shaft and a girth gear. Spectrum analysis of the motor current shows two trains of sidebands lines: one at the quill shaft frequency (2.26Hz) and the other at the mill frequency (0.277 Hz). The lines are magnified around 40Hz

Now, Click on Ball Mill Sizing under Materials and Metallurgical Now, Click on Shaft Length under Ball Mill Sizing The screenshot below displays the page or activity to enter your values, to get the answer for the shaft length according to the respective parameters which is the Applied Torque (T), Length of Shaft (L), Modulus of Rigidity (G) and Diameter of Shaft (D).

The formula for calculating shaft power | ball mill length: P = 7.33 x C X J X V cr x (1 – 0.937) x [1 – 0.1 / 29 – 10Vcr] x s.g. x L x D 2.3. Find the shaft power | ball mill length when the volume load percentage is 8, the %critical speed is 10, the bulk density is 3. the mill length is 14 and the mill internal diameter is 16.

In strip mills, in fine-section and wire millsthe rolling speedsare often so high thattapered roller thrustbearingsand sphericalroller thrustbearingscannotbe used. In these casesthe axialload is accommodated byangular contact ballbearingsor deep groove ball bearings. For the back-up rollsoflarge four-high strip and foilmillsa deep
