T.R. Crompton, in Determination of Metals in Natural Waters, Sediments and Soils, 2015 6.3.3 Grinding of Samples. The air-dried sample is ground until the whole of the sample, excluding stones, passes through a 2-mm mesh sieve. There is a limited range of apparatus available for grinding, but the Rukuhia-type grinding machine is suitable (this is obtainable from D. Mackay, 85 East Road ...

It is a wet ball mill test. A 1.5 kg graded aggregate sample (retained on the 9.5 mm sieve), 2 L of water and a 5 kg charge of 5 mm diameter steel balls are placed in a stainless steel jar mill and rotated for 2 hours. Loss is the amount of material passing the 1.18 mm sieve expressed as a percent of the original sample …

A grinding mill grinds grains or similar foodstuffs, while the concept of the invention could also be applied to other feed materials. The grain is fed at a controlled rate to an impeller chamber, ground by the impeller until a small enough size to fit through a sieve, and separated into a sample cyclone stream and a bulk or waste cyclone stream.

Rocks larger than cobbles must be broken or cut into suitable sizes prior to crushing. Ball mill ("Pulverisette 5" from Fritsch) performs high-speed grinding of solid or liquid samples to an average fineness of < 1 μm (depending on the material being milled). The max. initial sample size for hard materials is ca. 1 cm.

Fixed closed size setting of 3.35 mm was used. For the crushing tests the sample was passed through the crusher only once. For the sample preparation for the grinding test the sample was continuously sized using a 3.35 mm sieve and the oversize was crushed again until all the material passed the sieve.
