The invention provides a raw material lifting device for a pulverizer. The raw material lifting device comprises a rotary shaft I, a roller I, a rotary shaft II, a roller II, a conveyor belt, carryingplates, vertical plates and leaf springs. The rotary shaft I is assembled to the lower end of the interior of a support. The roller I is assembled on the annular side face of the rotary shaft I. Therotary shaft II is assembled to the upper end of the interior of the support. The roller II is assembled to the annular side face of the rotary shaft II. The roller I is connected with the roller II through the conveyor belt. The carrying plates are fixed to the outer surface of the conveyor belt. Each vertical plate is fixed to the ridge line of the rear portion of the upper side face of the corresponding carrying plate. Each leaf spring is mounted on the front end face of the corresponding vertical plate. A material basket is mounted on the upper side face of each carrying plate. The raw material lifting device facilitates conveying of materials in the crushing process. The raw material lifting device is simple in structure, convenient to operate, small in occupied space and high in working efficiency.
