Ball Mill Positioning | Benshaw Inc. - Applied Motor Controls

Working with a long time customer and local Benshaw partner in the motor controls industry, Benshaw has successfully applied a 480VAC 700 HP AC variable frequency drive for positioning a medium voltage synchronous motor driven ball mill. The variable frequency drive powers the 4160Volt – 3500HP synchronous ball mill motor during positioning to smoothly rotate the ball mill and bring it to the proper position for maintenance.

Effect of mill speed and slurry filling on the charge

Aug 01, · The laboratory ball mill (∅305 × 150 mm) used for this wet grinding is shown in Fig. 3, it mainly formed of a motor, an inverter, a mill shell, a torque sensor and a data acquisition system. The mill shell was constructed from a steel drum, mounted on the mill shaft, and lined with 12 pieces of trapezium lifters equally spaced.

Cement Mill Drives | Transmission (Mechanics) | Engines

Function: A cement mill is a drive used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.

A guide to maximising ball mill circuit classification system

2. From the ball mill discharge size distribution calculate the %+75 μ as: 100 – 26.5% = 73.5% +75 μ. 3. Calculate the CSE as the average: (80.7 + 73.5) ÷ 2 = 77.1% + 75 μ. In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that
