The sample grinding device is mainly used to grind samples into fine powder or mixture for subsequent analysis or experiments. After the sample is ground by mortar, its particle size can be controlled to make it suitable for different types of analysis or experimental needs. The mortar grinder can also be used to mix multiple samples together to prepare a uniform mixture. The mortar grinder can greatly reduce the time and workload of sample processing and improve laboratory work efficiency;

[0003] When the sample is to be tested, the sample is placed inside the mortar, the electric telescopic rod is started, the electric telescopic rod drives the grinding motor to move downward, the pestle is inserted into the mortar, and the grinding motor is started again, the grinding motor drives the pestle to rotate, and the pestle grinds the sample inside the mortar. Since the grinding motor generally drives a single pestle to grind the sample, it takes a certain amount of time to grind the sample, which limits the working efficiency of the sample grinding device. Therefore, we propose a sample grinding device for testing. Utility Model Content
