Abstract
A device for crushing, pulverizing, classifying and dedusting dry grind or dewatering wet grind ores. The ore is fed into a trough in which is seated crusher, spacer and pulverizer bars vibrated by an electromagnet energized by a low frequency electric pulse generator. The ore, receiving repeated blows as it is vibrated between the bars and the bottom floor of the trough, is reduced in size and moved along the trough for classifying and dedusting dry grind or classifying and dewatering wet grind.
Claims12
Apparatus for crushing solid material, comprising a base, a trough having a material inlet end and a pulverant material outlet end, a power drive unit mounted on said base, for delivering a vibratory force to said trough and for supporting said trough, a crusher bar in said trough for crushing material between said bar and said trough, and pulse generator means for energizing said power drive unit, whereby solid material is crushed in said trough by the action of said power drive unit.
