Sanxing Feirong supply SP series stirred beads mill without sieve and shaft sealing

This kind of beads mill can grind the material to sub-micron or nano-sized by using small gringding beads with a diameter of 0.1-0.2mm. This machine is espcially suit for expensive or small amount of particulate sample.

- Effective grinding/dispersing with pin/counter-pin turbine agitator at high speeds;

- Use of wear-resistance materials (Ceramic, Alloy steel, PU);

- Production of micron, sub-micron even nano-particles with narrower size distribution;

- Use of small beads 0.1-1.2 mm as grinding media;

- Sealless structure, without sealing leakage;

- Discharge and beads separation without sieve; 

- No over- grinding due to on-time discharge of fine particles from the grinding chamber;

- Effective energy consumed on mainly grinding coarse particles during the process, and the energy utilization efficiency is increased by > 50%.

- Adjustment of temperature by controlling flowrate, especially for thermo-sensitive materials.

Operating Principle：

Model SP vertical discharge-sieve-free stirred beads mill is developed/designed for production of intermediate and high viscous suspensions based on the patent technology. In continuous operation, small beads in the grinding barrel are stirred with pin/counter-pin turbine agitator at high speeds. The effective grinding/dispersing is done between small beads in the diameter range of 0.1-1.2mm. The suspension to be ground is continuously conveyed centrically into a top-inner product pipe without any sieves. The beads separation at the top end is carried out by means of centrifugation. The beads separated are re-circulated into the grinding barrel for continuous grinding.

Applications:

Electronic materials, Inkjet, Ceramic, Minerals, Optical materials, Dyes, Paper-fillers, Rubber, Cosmetic, Bio-materials, Pharmacy, Traditional Chinese medicine, Pesticide, Chemical fertilizer, Pigment, Chemical products, Coating, Printing ink, etc..
