This voltage, while ideal for distribution, is too high for use on coalface machines or the smaller machines elsewhere ...
Solving the three biggest coal screening challenges
By switching to a high-vibration screen, most coal mines will see an increase upwards of 40% in production. Though pushing more material across the screens may result in slightly more frequent screen change outs, the revenue generated by increased production and a better-quality product more than offsets the additional …
