In 1886, the Swedish poet and scholar, Viktor Rydberg first made the case for a cosmic mill grinding at the bottom of the sea in Germanic mythology, based on passages in Eddic and skaldic poetry. His findings were published in the first volume of his work Undersökningar i Germanisk Mytologi,subsequently translated into English in 1889, as

Contactresult in mills operating at optimum speed if low media charge or low consistency is used in the mill. The use of lifter bars welded or bolted to the mill cylinder in unlined mills reduces media slippage in mills whose rotational velocity is slow. Lifter bars are recommended when the grinding media charge is below 45 percent of the mill volume.

ContactAnother common mill type uses a combination of both autogenous grinding and ball mill grinding—these mills are known as Semi-Autogenous Grinding or SAG mills. Water is added to the ore during the grinding process. This creates ‘slurry’, which is then used to transport the ore throughout the remainder of the extraction process.

The cantilevered shaft, coupled to the motor and gearbox, allows quick and simple removal of the grinding chamber to expose the mill internals for maintenance.

ContactGrinding containers with volumes of 0.15l, 0.3l, 0.6l and 1.4l can be used for processing highly fluid to viscous pumpable suspensions in amounts >500ml. A pump located next to the mill feeds the suspension into the DYNO®-MILL MULTI LAB. The grinding beads are re tained in the grinding chamber using a dynamic gap separator,

ContactIn grinding, operating Efficiency compares the operating work index of a comminution machine to the Bond work index from bench scale crushing and grindability tests or/and pilot plant tests. Economic Efficiency is comparing the income from production to the planned income from production. Energy as consumed in comminution machines and the required energy as determined, from bench scale

ContactThe Bond Ball Mill Grindability Test (Bond, 1952, 1961) gives the Bond Ball Mill Work Index. This Index expresses the resistance of a material to ball milling; the higher the value of the Bond Ball Mill Work Index, the more difficult it is to grind the material using a ball mill. This Index is widely used in the mineral industry for:
