Lab Three Rolls Grinding Mill Grinder With Zirconia Ceramics Roll Precision Grinding Machine

Introduction:
Three-roll grinding mill is mainly applied for grinding paste material of paints, ink, pigment, plastic, food, etc. It is suitable for grinding neither the material containing acid and alkali components nor the materials which would corrode rollers. This machine is suitable for high viscosity material, such as printing ink, offset ink and lithographic ink. It is equipped with three rollers which are in the horizontal level. With the rollers extruding and milling at different speeds, the material is ground normally for two times, the hard or high viscosity material is ground for more times, and then high-quality finished products of 3-18um are obtained (testing with a fineness scraper).

Technical Parameters:
Power: 110V 60Hz 750W
Diameter of roll (mm): φ65
Length of roll (mm): 125
Feeding roll rotational speed (r/min): 32
Middle roll rotational speed (r/min): 89
Discharging roll rotational speed (r/min): 250

The three adjacent rolls of the three-roll mill rotate at the progressively higher speeds. The material, usually in the form of paste, is fed between the feeding roll and the central roll. Due to the narrow space between the rolls, most of the paste initially remains in the feeding region. The part that makes it pass through the first in-running nip experiences very high shear force due to the different rotation speeds of the two rolls. Once leaving the feeding region, the material that remains on the central roll moves through the second nip between the central roll and the discharging roll. This material is subjected to the much higher shear force due to the higher speed of the discharging roll and a gap typically smaller than the gap between the feeding and central rolls. Then a knife blade scrapes the processed material off the discharging roll and the paste rolls down the discharging roll. This milling cycle can be repeated for several times to maximize dispersion.

How to use?
1. Install the handwheel;
2. Install the baffle;
3. Connect the power supply (110V 60Hz);
4. Connect the water pump (the machine does not include the water pump and pipe);
5. Add a small quantity of materials, activate the switch, and proceed to adjust the machine.
