lab three roll mill supplier for paint

Three roller mills are referred to as three roller mills. Three roller mills can be divided into two types: experimental three roller mills and production three roller mills.

Three roller mills are the most effective grinding and dispersing equipment for high viscosity materials. It is mainly used for grinding of various paints, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber and other liquid slurries and paste materials.

How does the three-roller mill work?

The three roller mill achieves the grinding effect through the mutual extrusion of the surfaces of the three horizontal rollers and the friction at different speeds. It is the most effective grinding and dispersing equipment for high viscosity materials.

It is mainly used for grinding various kinds of paints, inks, inks, oil paints, coatings, food, chocolate, cosmetics, pharmaceuticals, and other paste materials (not suitable for grinding raw materials that are sufficient to cause roller corrosion). In recent years, there has also been a greater development in the field of cable material, human leather plastic, soap and lead core raw materials production, so the machine has become the main equipment for these manufacturers to grind fine materials.

Common Faults and Solutions of Three-Roller Grinding Machine

Inevitably in the process of our use of some failures, through long-term production experience, for the production of three-roller mill, operation, use of failure to do a simple analysis, the following treatment methods are introduced.

• Check whether the roller surface is clean, there is no foreign matter between the rolls, check whether the undercutting knife is sharp, check whether each lubricating part is sufficiently lubricated, loosen the roller, undercutting knife and gear tip in turn, prepare the slurry receiving tank (must be cleaned) and open the cooling water valve.

• Press the start electric button to start. Properly press the gear tip, immediately load (paint) Rotate the hand wheel, adjust the slow roller and fast wheel, lean toward the middle, observe the roller surface parallel, adjust the roller loosely. Adjust the pressure of the lowering knife, the size of pressure, to the knife blade blade all roller surface paste solid not bend. Adjust the gear tip tightness, to not leak as the limit. Adjust the cooling water. Observe the current meter pointer, not to exceed the rated current. Take the pulp to check the fineness, and then adjust the roller tightness and cooling water according to the fineness.

• After the lacquer is finished, use a small amount of the same kind of lacquer or solvent to wash the drum quickly. Loosen the drum, loosen the gear tip and loosen the lower knife. Press the electric button to stop. Close the cooling water valve. Clean the gear tip and paint catcher plate, wipe all the machinery clean and clean around the equipment site. Stop for a long time and apply a layer of 40# machine oil to the drum to prevent the drum from rusting.
