The grinding jar of the tissue grinder swings in an arc in the horizontal direction under the driving action of the swing arm. The material in the grinding jar is subject to the inertial impact force of the grinding ball and the collision and grinding shear force with the high-speed movement of the grinding jar, thereby achieving the effect of crushing and grinding. The superposition of the high-speed movement of the grinding jar and the movement of the grinding balls in the grinding jar makes the sample fully mixed.
Using multiple small-diameter grinding balls during grinding can greatly improve the uniformity of the material. Tissue cells can be disrupted by using a large number of small beads (such as glass beads). The huge impact and friction between balls can effectively break cells.
The tissue grinder is a product specially developed for processing small quantities of samples in the laboratory. It is not only suitable for fine crushing and fine grinding of hard, medium hard and brittle samples, but also suitable for crushing and grinding of soft, elastic, fibrous and other materials.
The tissue grinder can crush and grind many materials including fibrous tissue, bones, hair, chemicals, pharmaceuticals, minerals, ores, alloys, glass, ceramics, soil, sludge, and grain particles. For most materials, the equipment only takes tens of seconds to crush, grind and mix the materials.
The tissue grinder runs very fast, so the materials can be processed in a very short time without significant temperature rise. Therefore, this equipment can avoid the impact of temperature on the experiment, so most materials can be ground and mixed at room temperature.
