Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either

Trees: stump removal and treatment / RHS Gardening

Although stump grinders can be hired, they are potentially hazardous and are only for gardeners confident that they can use machinery safely. Some roots will inevitably be left in the ground but the majority should eventually rot down. It is worth specifying how deep you would like the stump ground to. Shallow grinding, 20-25cm (8-10in), is normally sufficient for laying turf, but you should allow for
