Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0015] In the figure: moving grinding part 1, fixed grinding part 2, fixed shaft 3, guide hopper 4, rotating cylinder 5, grinding gap 6, support rod 7, connecting plate 8, collecting tank 9.

[0016] Such as figure 1 A graded grinding device shown includes a vertically arranged drum 5 , and the outer wall of the drum 5 is provided with elongated ribs for increasing the torsion resistance of the drum 5 . The interior of the drum 5 is provided with a coaxial fixed shaft 3, and four grinding mechanisms are arranged between the fixed shaft 3 and the drum 5. The grinding mechanisms are vertically distributed from top to bottom, and the grinding gap 6 of the grinding mechanism is from top to bottom. down gradually. The grinding mechanism includes a movable grinding part 1 and a fixed grinding part 2. The fixed grinding part 2 is conical in sh...

Abstract

The invention relates to medicine grinding equipment, in particular to a classified grinding device. The classified grinding device comprises a vertically arranged rotating drum. A fixing shaft is coaxially arranged in the rotating drum, and grinding mechanisms are arranged between the fixing shaft and the rotating drum. Each grinding mechanism comprises a movable grinding piece and a fixed grinding piece, wherein each fixed grinding piece is conical, and the fixed grinding pieces are coaxial with the fixing shaft. The fixed grinding pieces are arranged on the fixing shaft in a sleeving mode and fixedly connected with the fixing shaft, and material channels are arranged between the fixed grinding pieces and the rotating drum; each movable grinding piece is conical, and a conical cavity matched with the corresponding fixed grinding piece is formed in each movable grinding piece; the movable grinding pieces are fixedly connected with the rotating drum, feeding inlets are formed in the tops of the movable grinding pieces, and funnel-shaped guiding hoppers are arranged on the tops of the movable grinding pieces; the vertical projective plane of each guiding hopper is larger than that of the corresponding fixed grinding piece; the multiple grinding mechanisms are provided, and grinding gaps between the movable grinding pieces and the fixed grinding pieces are gradually reduced from top to bottom. The classified grinding device has the beneficial effect that the production efficiency is improved.

Description

technical field [0001] The invention relates to grinding equipment for medicines, in particular to a graded grinding device. Background technique [0002] In the pharmaceutical industry, some raw materials used in the production of medicines need to be ground before use. The existing grinding devices generally directly grind the raw materials from the particle state to the powder state. When the particle size of the raw material has multiple specifications, if the grinding is performed at the same time, the particles with large particle sizes will play a supporting role in the grinding device. Particles with small particle size will pass through the gaps formed between large particles, so that the particles with small particle size are not sufficiently ground, and repeated grinding is required to meet the requirements, resulting in low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a graded grinding device to so...
