· Roll Crushing VS Stamp Milling Compared. Comparison between Rolls and Stamps: As the subsequent treatment of an ore determines its method of crushing, no accurate general comparison of stamps and rolls can be made. A comparison is only possible in the special cases where both methods of crushing are applicable.
· A strain gage is an instrument used to calculate the strain acting upon an object and converts changes of electrical resistance into desired values, i.e. ("force, pressure, tension, weight, etc.") (Omega). The electric resistance strain gage was first reported in 1856 by Lord Kelvin, who used copper and iron wires
The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).
