The samples can be taken from adits pits trenches etc in the ore body or they can be crushed drill it is helpful in anticipating variations in feed rates to know the grindability of the various ore types in a deposit for mill selection grindability tests should be run on composite samples representative of the blended mill feed
Ball mills are the allrounders used for the milling and homogenization of a broad range of samples prior to analysis they are advantageous for bringing samples into a homogenous pulverized state and preparing them perfectly for either additional sample preparation steps like extraction digestion and filtration andor for subsequent analysis like xrf spectroscopy
Ball mills are the most effective laboratory mills for rapid batchwise comminution of mediumhard soft brittle fibrous temperaturesensitive and moist samples down to the finest particle size the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding
Fritsch planetary ball mills highperformance allrounder in routine laboratory work the planetary mill pulverisette 5 premium line with 2 grinding stations is the ideal mill for fast wet and dry grinding of hard mediumhard soft brittle and moist samples as well as for mechanical alloying mixing and homogenising of larger sample quantities with reliable results down into the nano
The lack of shrouding allows the use of a water jacket on the tank in an internally agitated ball mill providing cooling or heating to aid in the grinding process unlike planetary ball mills attritors offer the advantage of being able to sample the material during milling without having to stop the process formulation adjustments and grind
If a ball mill contained only coarse particles then 100 of the mill grinding volume and power draw would be applied to the grinding of coarse particles in reality the mill always contains fines these fines are present in the ball mill feed and are produced as the particles pass through the mill
