The invention relates to a pulverizing device, in particular to a solid chemical raw material pulverizing device for a chemistry class in a senior middle school. By the solid chemical raw material pulverizing device for the chemistry class in the senior middle school, time and labor are saved, the experiment is visual, and solid chemical raw materials are pulverized thoroughly. In order to solve the technical problem, the solid chemical raw material pulverizing device for the chemistry class in the senior middle scheme comprises a bottom plate, a collecting box, a cylinder I, a cylinder II, a spring, a wedge block, a breaking box, a cylinder III, a discharge opening, a cylinder IV, a left breaking plate, a valve, a right breaking plate, a contact roller, a funnel, a grinding roller I, a motor I, a motor II, a grinding roller II and a strut, wherein the collecting box, the strut, the cylinder I and the cylinder II are successively arranged on the bottom plate from left to right; the left end of the strut is connected with the funnel; and the motor I is arranged on the left side of the inside of the funnel. By the solid chemical raw material pulverizing device for the chemistry class in the senior middle scheme, effects of time and labor saving, visual experiments and thoroughly pulverizing are achieved.
