In the pharmaceutical industry, pharmaceutical intermediates are precursor compounds for producing active pharmaceutical ingredients, so their quality and purity directly affect the quality of the final product. The role of the grinder is to refine the pharmaceutical intermediates during the production process to meet specific particle size requirements.

[0003] The patent publication number CN109261319A discloses an intelligent grinding machine for pharmaceutical intermediates, including a bottom plate, a grinding device and a conveying device, wherein the grinding device is installed at the rear end of the bottom plate, and the conveying device is installed at the front end of the bottom plate. The present invention can solve the problems of manual grinding of existing pharmaceutical raw materials, poor effect of manual grinding, incomplete grinding, difficulty in batch grinding, inability to collect the ground pharmaceutical powder in time, resulting in waste of medicines, low production efficiency, long time consumption, etc., and can realize the function of automatically grinding the pharmaceutical raw materials into powder, automatically grinding the pharmaceutical raw materials into powder, with good grinding effect, batch grinding, timely collection of the ground pharmaceutical powder, high production efficiency, short time consumption, etc.

[0004] The prior art has the following defects:

[0005] Low grinding efficiency: Existing grinders generally have only one grinding cylinder, the volume of which is not fully utilized, and the contact area between the material and the grinding medium is small, which leads to decreased efficiency. In addition, the material fluidity is relatively poor, resulting in the material being concentrated in a certain area and not fully participating in the grinding, thus affecting the overall grinding efficiency. Therefore, a dispersion device is required to disperse the material, grind it in different areas, and increase the material fluidity by changing the grinding speed, so as to improve the grinding efficiency and shorten the production cycle.

[0006] Unable to quickly adjust the required particle fineness: The rotation speed, media size, etc. of existing grinders are mostly fixed parameters, which cannot be flexibly adjusted according to different materials and fineness requirements, resulting in the inability to quickly achieve the required particle fineness. When the required particle fineness needs to be adjusted, the device often needs to be disassembled and replaced, which is troublesome. Therefore, it is necessary to set up a device that can internally adjust the required particle fineness to achieve rapid response and switching, as well as improve the efficiency and flexibility of the grinder.
