Arrange three rollers horizontally or at an incline, rotating in opposite directions at varying speed ratios. The contact generates pressure and shear force to disperse the material (reducing particle diameter). First, feed the material between the inward-rotating, contacting, and pressurizing feed roller (rear roller) and the center roller. The material is compressed by these two rollers and torn (sheared) at different speed ratios, making its particles finer to achieve a grinding effect.

Suitable for fine grinding of various medium to high viscosity liquid raw materials, such as paints, inks, pigments, dyes, cosmetics, food ingredients, and more.
Three-roll millWorking Principle:

Feature Description:
...Three-roll millThe roller material is made of high-density chilled cast iron and alloy steel through precision grinding, with a surface hardness of over HR70 degrees. It has strong toughness and is not affected by external pressure or temperature.
Property: The cylindrical rollers undergo high-precision grinding, achieving precise and fine roundness, enabling the ground product to reach a fineness of below 5μm, resulting in uniform and fine high-quality products.
The roller can be used normally for over 15 years without the need for repair or grinding.

...The transmission structure device of the roller is equipped with a high-load double row self-aligning spherical roller bearing.

Three-roll millDuring operation, it can automatically adjust the balance and positioning of the rollers, maintaining the precision of the gap between the rollers at all times.

...Three-roll millThe principle of the grinding function is to utilize the friction generated by different rotational speeds between rollers to achieve the grinding and mixing effect of product raw materials. The speed ratio of the three rollers is 1:3:9 (feed slow roller: middle roller: discharge fast roller).
...The forward and backward adjustment gears of the front and rear rollers are equipped with inclined handle safety pins to prevent the rollers from being adjusted too tightly, causing excessive pressure, or sudden external pressure during roller operation.
Automatically cut off the safety pin to eliminate excessive pressure, thereby protecting the roller from damage.
...Three-roll millAll three rollers are equipped with a cooling system. Cooling water pipes go directly into the center of the rollers, allowing the cooling water to circulate inside the rollers before flowing out from the outer ends of the roller shafts. This cools the temperature generated by friction during roller operation, preventing heat buildup from roller friction during material grinding, and ensuring the quality of the ground materials.
