Laboratory Small Bead Grinding Mill/Horizontal Sand Mill

1. Application: 

Root laboratories sand mill is widely applied in lab study and trail production of paint, dye, ink, magnetic material, pesticide, ceramic, paste, adhesion etc. With low investment and high working effect, Root laboratories sand mill has won smile from clients over 10 countries. Root lab use horizontal sand mill has been a wise choice for lab study of institute or trail run of factory worldwide. 

2. Working Principle:

The working force between grinding media and material is generated from the high-speed rotation of dispersing device(disc, pin or paddle). Under the force of viscous resistance, Grinding media and material moves along with dispersing device and be thrown to the cylinder inner wall by centrifugal force, forming double-circle turbulence. The strong inter-movements of grinding media form great cutting, pressing and abrasive force, making the material change shape and generate stress-field. When that stress reaches material yielding and breading limit, the material will be deformed plastically or pulverized. The un-pulverized material will be thrown back to the cylinder inner wall by centrifugal force. In this zone, the density of grinding media reaches the highest point, thus making the pulverization more powerful. The fine final products will be separated from grinding media by separator and be discharged from the sand mill.

3. Machine Features

1)Turbine, disc or pin type inner structure of laboratories sand mill allows high grinding efficiency. It can reach 100 nanometer for D90.

2)According to the process characteristic, the rotation rate of the dispersion shaft can be steplessly changed by the frequency conversion technology to get the best process parameters.

3)Pressure and temperature automatic control devices ensure safe production.

4)Root laboratories sand mills are applied with world-class pneumatic diaphragm or peristaltic feeding pump, suitable for small production

5)Owning the same production effect with industrial sand mill, experimental result of lab use sand mill could be applied in large production directly.

6)Reasonable design for inner and outer structure allows stable performance with no vibration and noise.

7)Ceramic and PU material are optional.

8)Frequency control and PLC are optional

9)With CE&ISO9001:2008 qualification.

10)Dynamic or static separating system for different material to ensure smooth discharging.
