Stirred Vertical Ball Mill Grinding System for particle size reduction in laboratory and production scale.

SANGXING FEIRONG is proud to offer superfine particle reduction grinding attritors. This is continuous attritor mill which has a compact vertical design suitable for continuous production of large quantities of materials.

We provide grinding mills for laboratory use with a grinding cylinder volume of 0.5L, but also industrial grinders with a grinding cylinder volume of 100L. The grinding structure of the bead mill and the material of the grinding cylinder can be customized according to the materials that the customer needs to grind, to ensure the purity of the grinding materials to the utmost extent.

The SP series bead mills can efficiently perform the functions of homogenization, emulsification, dispersion, mixing, shaping, and grinding of materials. It can also grind the materials down to nanometer level.

SANGXING FEIRONG has developed a vertical bead mill without shaft seal and screen to address the problems faced by traditional horizontal grinding attritors, including the leakage and damage of mechanical seals, blockage of separating mesh, difficulty achieving nanometer particle size, non-uniform particle size, and low grinding efficiency. The grinder without shaft seal and screen prevents the leakage of coolant caused by the damage of seals and the blockage of separating mesh for grinding medium as small as 0.1mm, thus realizing nano-scale grinding.

Operating in a continuous mode, the grinding mill sends the material to the grinding chamber through the feed diaphragm pump for grinding. Once fully ground, the material is discharged from the top of the shaft through the discharge diaphragm pump. This attrition mill can realize fractional separation and classified grinding during operation, achieving results with uniform particle size distribution and high energy utilization.

In classified grinding and fractional separation, the whole grinding zone can be divided into inner and outer grinding zones by cooperation of the separation turbine, the agitation rotor, and the inner stator so that large particles can be ground longer and small particles shorter to realize uniform particle size distribution.
