The grinding media are iron and steel balls for a ball mill with a diameter of 15150 mm; carbide balls with a diameter of 820 mm; iron or steel cylinders (such as "cylpebs"); round steel rods with a diameter of up to 130 mm and a length corresponding to the length of the mill drum; and silicon or ore pebbles up to 200 mm in size, large pieces of crushed raw material.
· The Zourerat iron ore mine has two m diameter × m wide HPGR units treating 1400 t/h each of aerofall mill pebbles. The feed is − 25 + mm and has a ball mill work index of 12–14 kWh/t. The iron ore has low to moderate abrasion characteristics. Figure shows the Zourerat iron ore .
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 to 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 2 major western phosphate rock ore deposits are loed in southeastern Idaho and ... Dried or calcined rock is ground in roll or ball mills to a fine powder, typically specified as 60 percent by weight passing a 200mesh sieve. Rock is fed into the mill by a rotary valve, and ground rock is swept from the mill by a circulating air stream.
Mesh is a measurement of particle size often used in determining the particlesize distribution of a granular example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turnkey ore ...
Energysaving Dolomite Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silie, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grindable materials.
· Sieving is a practical and cost effective way to determine particle size distributions for coarser materials. Two accepted scales are the US Sieve and Tyler Mesh or equivalent scales. A table is provided that allows correlations between the two scales.

· In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
but for AG/SAG mill analyses the standard 14mesh () sieve is typically used. The rod mill work index is computed with an equation very similar to that of the ball mill test, as follows: It is common to observe a difference between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore
