How to choose the specifications of the grinding beads of the tissue grinder.
Tissue mill and ball mill are a kind of grinding equipment that is widely used in laboratories, and grinding beads are an important part of it.
1. Determine the material of the grinding beads.
First of all, the material of the grinding beads needs to be selected according to the specific grinding needs. Commonly used grinding bead materials include glass, ceramics, zirconium silicate, corundum, etc. Each material has different hardness and abrasion resistance, which is suitable for different grinding media and experimental requirements. For example,Zirconia grinding beadsIt has high hardness and wear resistance, and is suitable for grinding hard materials; It has good toughness and high temperature resistance, and is suitable for grinding in high temperature environment.
2. DeterminationZirconia grinding beadsparticle size.
The particle size of the grinding beads is another important specification parameter. The particle size directly affects the grinding effect and experimental results. The smaller the beads, the more times they contact the material, the larger the specific surface area, the larger the beads, and the stronger the impact.
3. The use of zirconia grinding beads in the grinding instrument.
1.It is suitable for grinding and crushing various plant tissues including roots, stems, leaves, flowers, fruits, seeds and other samples;
2.It is suitable for grinding and crushing all kinds of animal tissues including brain, heart, lungs, stomach, liver, thymus, kidney, intestine, lymph nodes, muscle, bones and other samples;
3.It is suitable for grinding and crushing fungi and bacteria including yeast, E. coli and other samples;
4.It is suitable for grinding and crushing of food and medicine;
5.It is suitable for grinding and crushing volatile samples, including coal, oil shale, wax products and other samples;
6.It is suitable for grinding and crushing plastics, polymers including PE, PS, textiles, resins and other samples.
4. Determine the filling amount of zirconia grinding beads.
Finally, it is also necessary to determine the amount of filling of the beads in the tissue grinder. The size of the filling volume not only affects the grinding effect and experimental results, but also affects the life and operational efficiency of the equipment. When choosing the amount of filling, it is generally enough to occupy 1 3 tubes, or it can also be matched with large and small beads.
In summary, there are several factors to consider when choosing the right bead size for a tissue mill, including material, particle size, shape, and filling amount. In practical applications, it is necessary to comprehensively consider the experimental conditions and specific needs to select the appropriate specifications. At the same time, it is also necessary to pay attention to the quality and stability of the grinding beads to ensure the accuracy and reliability of the experimental results.
