The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.

Impact crushers (e.g., hammer mills and impact mills) employ sharp blows applied at high speed to free-falling rocks where comminution is by impact rather than compression. The …

known crushing methods [6]. Impact (rotary and hammer) crushers are designed for impact crushing of various brittle materials using beaters rigidly fixed to a rotor rotating around a horizontal axis [7], while destruction occurs due to splitting. The destruction of brittle rocks by impact and compression requires different energy

Cone Crusher Motor Sizing. Hard limestone, having an impact strength of 15, is fed from a secondary crusher set at 3¼-in. open side setting, producing stone having 80 percent minus 3¼-in. The product of the secondary crusher is screened at 5/8-in. The screening results in 5 percent minus 5/8-in. material in the tertiary crusher feed.

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and …
