Pebble Mill Grinding. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer. The Tube Mill uses iron or steel balls as the grinding media, and liners of various metals and alloys.
Semi-Autogenous Grinding (SAG) Mill. Wet or dry. Higher capacity than A-G mill grinding. Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to .

FAG mill model The FAG mill model is essentially identical to that to the SAG mill model given as Eq. [8] except that it is applied as an equivalent series of reactors(8,9) with various degrees of recycle of the material rejected back to the mill by the grate, as indicated in Figure 2.

The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. Pebble mill
Polycom units are designed for throughput rates in excess of 3,000 t/h. The mill feed material can be dry or moist and with particle sizes ranging from below 1 mm to more than 75 mm. If required, the material can be dried in screens or air separators in a closed circuit grinding system.

Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ball-mill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 0–30% pebbles, by volume, with savings in energy and ball consumption increasing progressively.
The +100mm lump material and -25mm fines reported directly to the AG mill feed. The proportion of +100mm material in the primary crushed product was very high, at approximately 40% of the total primary crusher product. This material was building up in the AG mills, limiting throughput.

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

All Answers ( 4) If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling by avoiding local impact between the balls. There should be atleast 25% empty place in the milling jar after feeding balls and the material while high energy impact. There is no such thumb rule for powder to ball ratio.
The Pebble Mill format returned in 1988 as Daytime Live, renamed Scene Today and finally Pebble Mill. There was a Pebble Mill spin-off during the 1970s, when BBC 1 rested its main Saturday chat show, Parkinson. BBC Birmingham was commissioned to produce a late night replacement.

Thus, the inclusion of iron, from the balls and the mill body, in "face powder" is highly undesirable since such iron imparts a brown tint to the powder, and for this reason cosmetic and similar materials are usually ground in a mill having a ceramic body and with smooth natural pebbles as the grinding medium; that is, in a pebble mill.
