product description:
the mortar grinder (patented product, counterfeiting must be punished! '2018200735340) is based on imitating the traditional manual grinding method, through the friction and squeezing of a mortar and pestle, so as to complete the pulverization of the sample. after the sample enters the feed port, it moves inward along the direction of the mortar movement. after hitting the scraper, a part of the sample gathers on the upper and lower contact surfaces of the mortar and the mortar, and another part of the sample enters the mortar along the wall of the mortar. the back contact surface of the mortar and the mortar, this cyclic movement ensures the uniform crushing of the sample. compared with the mortar, the mortar is an eccentric design. on the one hand, the mortar drives the mortar to rotate, and the friction force is generated by the contact with the sample to crush the sample; on the other hand, the weight of the mortar itself and the adjustable elastic force acting on the axial direction of the mortar are produced. the pressure crushes the sample.
main feature
*easy to clean
*suitable for dry grinding, wet grinding and freezing grinding
*optional pretreatment for rough samples
*the sample volume can be increased through the feed window during the grinding process
*due to the wide selection of scraper materials, it can meet all application tasks (polyurethane, polytetrafluoroethylene, beech wood)
*the position of the mortar and pestle can be adjusted and moved without tools
*due to the scale adjustment, the pestle head can be set accurately and repeatably
*due to the setting of digital time and speed, the grinding result is representative
*suitable for samples with different heat sensitivity, so that the grinding results are accurate and well optimized
*due to the multiple selectivity of the material of the mortar and pestle of the grinding tool, it can meet all application tasks
