Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a turbine sand mill with a leak-proof sealing structure. Background Technology

[0002] Leak-proof and sealed turbine mill is a high-efficiency wet grinding equipment that can grind solid-liquid mixtures to the micron and nanometer scale. Its main structure includes a grinding chamber, turbine rotor, feeding system, drive system, sealing mechanism, and separation system. Its working principle is that the material enters the grinding chamber through the feeding system, the motor drives the turbine rotor to rotate at high speed, and the grinding media is agitated to refine the material through impact and friction. The finished product is separated from the media by the separation system. It is widely used in the fields of coatings, inks, nanomaterials, dyes, pharmaceuticals, and cosmetics. It can adapt to materials of various viscosities, and has both high efficiency and sealing properties, making it suitable for continuous production.

[0003] Leak-proof and sealed turbine sand mills require a feeding mechanism during use. Existing sand mill feeding mechanisms typically use a pneumatic pump to press the material into the grinding chamber. Compressed air drives the diaphragm to reciprocate and deform, changing the pump chamber volume to achieve material suction and feeding. While these mechanisms are leak-free and easy to clean, they are prone to uneven feeding during use, leading to arching and material overflow, causing many problems and reducing practicality.
