1. High efficiency and operability; 2. the different structure of dispersion disk determines the grinding efficiency. Compared with the others, our dispersion disk structure has a larger area to act on the zirconia beads, which has greater driving force and better effect; 3. the mechanical seal and stability of imported assembled double end face are better than other disc sand mills; 4. the gap between the dispersion disk and chamber is 15mm. After a period of time, if the contact part of the dispersion disk and the chamber is worn, the chamber service life can be prolonged by adjusting the position of the dispersion disk or cutting off the edge of dispersion disk; 5. the shell and end face are cooled, and the end surface cooling can reduce the material temperature; 6. the chamber and rod pin are made of high wear-resistant alloy, without loss and rust; 7. pressure protection, adjusted according to the viscosity of processing materials; 8. adopt imported zirconia beads, and the grinding fineness is good; 9. Grinding medium: 1.0-2mm, zirconia beads, good wear resistance; 10. CE and ISO 9001:2000 certification;
