Addition of pebbles to a ball-mill to improve grinding

Apr 01, 2017· There was a reduction in pebble consumption, as expected, when using larger rounded pebbles, to about 6% of total production. The grinding capacity, when using a mixture containing 25% pebbles, was the same as that with balls alone, resulting in a 13% saving in energy and an implied saving in ball consumption of 25%.

Addition of pebbles to a ball-mill to improve grinding

No loss in grinding capacity. Abstract Nkwanyana and Loveday (2017) used batch grinding experiments in a 0.6 m diameter mill to test partial replacement of steel balls (37.5 mm) for secondary grinding, by partly rounded pebbles (19–75 mm) from a SAG mill.

Nov 01, 2018· Secondly, they can build up in the mill and may reduce grinding efficiency. The pebbles recovered from a SAG mill trommel will typically be in the size range 15–75 mm. When the larger pebbles are used for composite milling, they will over time wear and become scats, but the remaining mass is a small fraction of the original mass.

Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

The Flint Pebbles does offer superior performance as the grinding media when compared to the natural pebble as a result of the higher hardness as well as, the higher resistance to abrasion. Another advantage is low pebble consumption.; 4.5 kg of the pebbles usually can be able to grid 1000 kilograms of the white ceramic body.

This means it does not produce enough pebble flow to ensure that the pebble crusher is consistently loaded. Under these circumstances, the feed ore is essentially fully ground within the SAG mill. This causes a lower production rate of pebbles (pebble production is 66 t/h), which in turn means the pebble crusher is oversized.
