Accurate and reliable drug testing is the key link to ensure that drugs meet the standards, have definite curative effects, and are safe. With the rapid development of the pharmaceutical industry, new drugs are constantly being developed and put into the market. Drug components are increasingly complex and diverse, which has put unprecedented high demands on the precision, efficiency, and reliability of drug testing. In the drug testing process, sample pretreatment is a very critical basic step, and drug grinding is an indispensable operation. The purpose of drug grinding is to process drug raw materials or preparations into a suitable form for subsequent analysis and detection. For example, solid drugs are ground into fine and uniform powders for component analysis, purity determination, dissolution test, and other testing work. However, traditional drug grinding devices have many defects and shortcomings when facing the growing demand for drug testing. Some traditional devices lack stability in structural design. During grinding operation, the rotation of the motor and the grinding parts will produce significant vibration.
