3 Chapter 11: Crushers, Mills and Stock Treatment 11-3 Crushers (CR) Includes motor and drive unit. Cone crusher for secondary and fine crushing for hard and medium hard materials such as limestone, stone and rock. CONE The cone crusher is a type of gyratory crusher. A conical head is gyrated by means of an eccentric driven through gears and a countershaft. The gyratory motion causes the conical head to approach and recede from the walls of the crushing chamber. The material receives a series of rapid blows as it passes through the crushing cavity. Mantle Diameter: Range: INCHES [510-2,130 MM]. : Default: *STAND* STAND - Standard head SHORT - Short head Primary and secondary crushing of hard and medium hard materials such as limestone, stone and rock. GYRATORY A conical head is gyrated by means of an eccentric driven through gears and a countershaft. The gyratory motion causes the conical head to approach and recede from the walls of the crushing chamber. The material receives a series of rapid blows as it passes through the crushing cavity. Mantle Diameter: Range: INCHES [510-3,045 MM]. : Default: *PRIME* PRIME - Primary crushing SECOND - Secondary crushing Overhead eccentric jaw crusher for primary and secondary crushing of hard, tough and abrasive materials, such as quartz, rock, glass and ferroalloys. Includes hydraulic toggle, motor and motor drive sheave and V belts. ECCENTRIC A moving jaw opens and closes against a vertical or slightly inclined fixed jaw by means of a toggle to crush the feed material. In single-toggle machines the moving jaw has an almost circular motion at the upper-end of the jaw plate and an elliptical movement at the lower-end. This motion causes the jaw plates to wear faster than double-toggle machines but also assists the flow of material through the crushing chamber. The trend is towards single-toggle machines because the increased wear is usually outweighed by the lower initial cost of the single-toggle machine. Rate: Range: 25-1,620 TPH [23-1,460 TON/H]. Product Size: Range: 1-16 INCHES [25-400]. G2 ICARUS Corporation, 1998.

4 11-4 ICARUS Reference Crushers (CR) continued Swing jaw crusher for primary and secondary crushing of hard and/or abrasive materials such as quartz rock, glass and ferroalloys. JAW A moving jaw is opened and closed by means of a pair of toggles against a vertical or slightly inclined fixed jaw crushing the feed material. (See ECCENTRIC crusher for additional information.) Rate: Range: TPH [ TON/H]. Product Size: Range: 2-8 INCHES [ MM]. Rotary crusher for coarse, soft materials, such as gypsum, phosphate rock, pitch, mica, cocoanut shells. ROTARY A toothed cone rotates inside a toothed shell. The clearance between the teeth on the cone and the teeth on the shell determines the product size. Driver Power: Range: 2-25 HP [ KW]. Single roll crushers are manufactured in light, medium and heavy duty constructions for the primary crushing of friable materials such as coal; medium hard materials such as coal, posphate rock and shale; and hard materials such as cement rock, iron ore and limestone. Single roll crusher for light duty primary and secondary crushing for coal and other friable materials. S-ROLL-LT Rate: Range: 140-1,470 TPH [125-1,330 TON/H]. Product Size: Range: 2-6 INCHES [ MM]. Single roll crusher for medium duty primary and/or secondary crushing for coal and other friable materials. S-ROLL-MED Rate: Range: TPH [ TON/H]. Product Size: Range: 2-8 INCHES [ MM]. Single roll crusher for heavy duty primary and/or secondary crushing for coal and other friable materials. S-ROLL-HVY Rate: Range: 175-1,000 TPH [ TON/H]. Product Size: Range: 2-8 INCHES [ MM].

5 Chapter 11: Crushers, Mills and Stock Treatment 11-5 Crushers (CR) continued Sawtooth crusher. Size reduction in tearing via toothed rollers for lumpy and friable materials, such as plastics, shale, charcoal, shells and bark. SAWTOOTH The particles are crushed between two rollers with sawtooth-like projections. Driver Power: Range: 5-40 HP [4-30 KW]. Reversible hammermill for secondary reduction of hard and medium hard minerals, stone, rock, limestone, low-silica ores/chemicals. Tertiary reduction of friables materials in closed circuit crushing. REV-HAMR Rate: Range: TPH [ TON/H]. Non-reversible hammermill for secondary crushing of bituminous and sub-bituminous coals, lignite, gypsum and some medium-hard minerals. HAMMER-MED Rate: Range: TPH [13-36 TON/H]. Non-reversible hammermill for hard materials (cement rock, limestone). SWING-HAMR Rate: Range: TPH [ TON/H]. Rotary breaker for simultaneous sizing and cleaning of run-of-mine coal. BRADFORD Rate: Range: 450-1,500 TPH [ TON/H]. Single rotor impact breaker for primary and secondary breaking of non-abrasive quarry rock and similar materials. S-IMPACT Rate: Range: 250-1,000 TPH [ TON/H]. G2 ICARUS Corporation, 1998.

6 11-6 ICARUS Reference Crushers (CR) continued Fine and medium crushing of soft non-abrasive materials. PULVERIZER Material Selection: Default: *CS*. Rate: Range: 300-8,500 LP/H [140-3,855 KW]. Driver Power: Range: 3-75 HP [ ]. Ring granulator for primary and secondary crushing of bituminous and sub-bituminous coals, lignite, gypsum and some medium hard minerals. ROLL RING Heavy cast steel rings, toothed and/or plain, at the end of rotating arms crush solid material by a combination of impact breaking and rolling compression.
