The mortar grinder is based on the principle of traditional manual grinding. The sample is crushed by friction and compression between the mortar and the pestle. When the sample enters from the feed port, it flows inward along the direction of the mortar movement. After hitting the scraper, part of the sample gathers on the upper and lower contact surfaces between the mortar and the pestle, and the other part enters the rear contact surface along the mortar wall. This cyclic movement ensures the uniformity of the sample crushing.

Eccentric design of pestle and mortar

The pestle is designed eccentrically relative to the mortar. First, the mortar drives the pestle to rotate, which creates friction with the sample, thereby crushing the sample. Second, the weight of the pestle itself and the adjustable elastic force acting on the axial direction of the pestle create additional pressure, further improving the crushing effect.
