The invention provides a pulverizing device used for new material processing. The pulverizing device used for new material processing comprises an outer grinding frame, an adjustable exhaust tube structure, a vibrating collection hopper structure, a hopper frame, a feed hopper, a buffering auxiliary pressing wheel structure, a thorn roller fixing frame, a new material grinding thorn roller, a double-shaft motor, a new material secondary pulverizing and grinding box structure, a fixed cross rod, a transmission V-belt, a left pressing roller, a right pressing roller, a driving wheel, supportinglegs, a new material guiding plate and an adjustable discharge hopper structure, wherein the adjustable exhaust tube structure is arranged on the left side of the outer grinding frame. According to the pulverizing device used for new material processing, a new material suction tube, an exhaust fan and an auxiliary exhaust fan are arranged so that the angle of a feed tube can be flexibly adjusted,and accordingly, new materials on the ground can be pumped conveniently; and an eccentric-axis vibrating motor, a vibrating plate, a limiting plate and a buffer spring are arranged so that the new materials can be vibrated and screened, and the situation that a large quantity of new materials are guided into the feed hopper, and consequentially blockage is caused is avoided.
