The alignment of the electric motor armature is disturbed, which ultimately contributes to strong brush arcing on the angle grinder. Collector shape disturbed. Collector, consisting of copper lamellas, has a 13.1.1.2 Medium-speed mill. Medium-speed mills are smaller than low-speed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition.

Evolution of Laboratory Mills and Grinders Lab Manager
In 1961, Fritsch GmbH registered its first patent for a laboratory planetary mill with cantilevered grinding bowls. Planetary ball mills can be considered the 'workhorse' laboratory mill, ideal for rapid and loss-free grinding of laboratory samples. Planetary ball mills are able to crush all manner of materials, including soft, elastic, hardAccording to Moema et al. (2009), in some instances, media wear can constitute up to 40–45% of the total cost of comminution. An estimated consumption of steel grinding media of around 600,000 tons p.a. in the 1980s already gives an indication of the scale of the problem ( Malghan, 1982).Consumption of steel grinding media in mills A review
