BROCHURE OF BEAD MILL

What is bead mill?

Wet grinding bead mill is a kind of machine for ultra-fine processing of solids in liquids. High energy input through the grinding media to create strong shear and impact force to dispersing, disaggregating and homogenizing the particles in the slurry.

What is the benefits ?

How to select a agitator bead mill, KEY points?

A. Flow rate of bead mill determines how long time the particles stay in the grinding zone,which affects the fineness of particles, output and particle size distribution.

B. Linear velocity of rotor determines the intensity of kinetic energy that transffered to the grinding media which affects the grinding efficiency, fineness of particles and wear loss of grinding media. 12-16 m/s is the generally operation speed.

C. Grinding media size selection is a key point, usually it is 1000 times of the target particle size. In theory, smaller the diameter of the beads is, more the contact point exists with smaller particle size achievements. However, It still depends on many factors like initial particle size. We need to choose the correct beads to fit different grinding requirements.

D. Generally, the grinding media filling rate is higher, the grinding efficient is higher. And the range of filling rate is around 75%-90% according to the viscosity of products. If too much higher will cause sieve blocking and high temperature problem.

E. Bulk density of grinding media-higher the bulk density will create stronger shear and impact force in the movement , better grinding efficiency it is.

F. Gap of separation screen is usually 1/2-1/4 times of the grinding media diameter. If the particle initial size is much bigger, it may block the sieve, hence, we need to consider two stage grinding process.
