Medical intermediate production grinding machine and grinding process

Abstract

The invention relates to the technical field of medicine grinding, in particular to a medicine intermediate production grinding machine and a grinding process.The medicine intermediate production grinding machine comprises a workbench, a grinding frame, a mounting block and a material shifting device, the grinding frame is arranged above the workbench, the middle of the grinding frame is of a downwards-sunken arc-shaped surface structure, mounting blocks are connected to the left side and the right side of the lower end of the grinding frame, the mounting blocks are fixed to the workbench, and the material shifting device is arranged below the grinding frame and located between the two mounting blocks. In the medicinal material grinding process, medicinal materials on the two sides in the grinding frame can be pushed to the middle so that sufficient grinding of the medicinal materials can be guaranteed, meanwhile, the surfaces of grinding rollers can be scraped when the grinding rollers roll and grind the medicinal materials, and the problem that the medicinal material grinding effect is affected due to the fact that the medicinal materials adhere to the surfaces of the grinding rollers is effectively solved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical grinding, in particular to a grinding machine for producing pharmaceutical intermediates and a grinding process. Background technique [0002] Pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. Such chemical products do not require a drug production license and can be produced in ordinary chemical factories. Pharmaceutical intermediates only need to reach a certain level. level, which can be used in the synthesis of medicines. [0003] At present, the preparation steps of pharmaceutical intermediates are as follows: put the crushed pharmaceutical raw materials into a grinder for grinding, then sieve and purify the obtained raw material powders, and finally mix various purified raw material powders to prepare Pharmaceutical intermediates, the existing grinding machine for the production of pharmaceutical intermed...

AI Technical Summary

Problems solved by technology

[0003] At present, the preparation steps of pharmaceutical intermediates are as follows: put the crushed pharmaceutical raw materials into a grinder for grinding, then sieve and purify the obtained raw material powders, and finally mix various purified raw material powders to prepare Pharmaceutical intermediates, the existing grinding machine for the production of pharmaceutical intermediates has the following problems in the process of grinding medicinal materials: a. The traditional grinding machine has the problem of insufficient grinding when grinding medicinal materials, and the obtained raw material powder particles are too large, which affects the quality of pharmaceutical intermediates. preparation of body; b. medicinal materials tend to disperse to both sides of the pressure roller during the rolling grinding process, resulting in that the medicinal materials on both sides of the pressing roller cannot be effectively ground, and at the same time, there is a problem of adhesion of medicinal materials on the surface of the pressing roller during the grinding process
