A tissue and towel machine can be complex. Many are about 165 feet to 246 feet long, but compared to a paper machine making paper for liquid packaging that can be up to 1,200 feet long, it is less complicated. Still, a tissue and towel machine might have 50 times more components in a series than a ball mill used in mining industry to crush ore.

Scheduled offline maintenance or failure of one of the Ball Mills (or its ancillary equipment) causes a 50% loss of milling production. Most of the maintenance results from time-dependent failure mechanisms (e.g. wear, corrosion or fouling). The crushing circuit has a mean running time to failure of 6 months.

Losses are exacerbated by the fact that critical single-line pieces of equipment often take a long time to replace. For example, it can take weeks or even months to get a new ball mill motor when there's high demand within the mining sector. Notable losses have also been incurred due to equipment failure on semi-autogenous grinding (SAG) mills.
Polycorp Ball Mill Liners provide long, low maintenance, service life. In addition to protecting and sealing the ball mill's steel shell, the liner imparts motion into the ball charge. Careful, intelligent, liner design can help to improve the operation and performance of grinding mills. Polycorp's Ball Mill Liners are designed and arranged so
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
The ball mills, the second stage grinding equipment, are 7.9m in diameter and 13.6m long, each with two 7800 kW motors. 52 magnetic separators are used in each of the processing lines. Two concentrate thickeners, each 45 metres in diameter and four tails thickeners each 90 metres in diameter.

Traditionally the ball mill (which is also known as the tube mill) is used for grinding and pulverizing of the cement clinker. Generally a closed circuit grinding philosophy is adopted for grinding operations where the product is continuously sieved and oversized particles are fed back to the grinding system. The vertical ends of such mills ...
