  • Rod mills, how they function

    The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

    The attritor mill is similar to the ball mill and uses much the same principles, but with slight variations. Essentially, the material is put into a fixed tank which contains a grinding media, this media could be carbon steel, ceramic, stainless steel, tungsten carbide, ceramic or, most commonly, chrome steel balls.

  • Modelling and validation of interactions between pulp, charge and mill structure in tumbling mills

    The smoothed particle hydrodynamic (SPH) method has earlier been used to model a ball charge and its interaction with the mill structure. The mesh free formulation and the adaptive nature of the SPH method result in a method that handles extremely large deformations and thereby suits modelling of grinding charges and pulp liquids.

  • How much gold is in a ton of ore?

    Answer (1 of 6): Varying amounts, of course. The amount of gold per ton of rock is called the ''grade''. Rock is ''ore'' if it has enough of the metal of interest, to make it profitable to mine and process that material. If you can''t mine it, treat it, and sell it at a profit, IT IS
