TWO-ROTOR INERTIAL CRUSHER Russian patent published in 2001 - IPC

FIELD: disintegration of solid minerals in concentration, metallurgical conversion or direct use of crushed products. SUBSTANCE: proposed crusher consists of housing with upper loading branch pipe, starting material divider, pair of loading chutes, lower unloading opening and two rotors mounted symmetrically at one level and rotating in opposite directions. Crusher has two sections: one section is provided with measuring-and-accumulating units mounted in loading chutes on sides of housing for delivery of material at angle close to 45 deg. relative to rotors found in this section; they are $-shaped in form. Self-contained drives for rotation of rotors and inertial mechanism are arranged in other section; inertial mechanism consists of two wheels which are proportionate relative to rotor diameters and are rigidly secured with rotor shafts for throwing them into engagement ensuring synchronous rotation. EFFECT: enhanced operational efficiency of crusher. 2 dwg, 2 tbl
