Flower or trim are immersed in a bath of ice and water and then agitated so the ice knocks the trichomes off the plant. The ice water bath is then drained over a series of filters to collect the trichomes. The trichomes are laid out to dry for roughly 24 hours and then pressed into very pure, clean hash.

further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2).

Ball Mill. Ball mills can operate in either wet or dry conditions. They are advantageous because they can achieve a very fine particle product size (refer to Table 1). Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small.
