Rolls of a three-roll mill

Three Roll Mill

The three-roll mill is mainly used for grinding materials of various viscosities and is one of the best wet grinding equipment. The dispersing and emulsification effect of the three-roll mill is excellent, especially for ink, paint, colloid, chocolate, plastic, cosmetics, etc., whether it is liquid slurry or paste material, the three-roll mill can work easily.

Details of Three Roll Mill

  • Safe scraper socket, Emergency-stop
  • Space-saving desktop models
  • Drip tray for easy cleaning

Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic

The material passes through the hopper and enters the three rollers of the three-roll mill. The speeds of the three rollers are different. The user can choose the three-roll mill with the appropriate power according to the characteristics of the material and production requirements. Three rollers are installed on the frame, and the rollers are placed on the same level. Through the three-roller mill, the surfaces of the fast, middle, and slow rollers are pressed against each other to achieve the desired grinding effect.

The common rollers of three-roll mills are generally made of chilled cast iron centrifugally, and the surface hardness can reach HS70° or more. The roller shaft is forged by several processes, not only is it not affected by external pressure and temperature, but the material produced is very uniform and fine, and according to the characteristics of the material, the minimum can reach 1 micron.

The roller shaft of the three-roll mill is not only made of chilled cast iron centrifugal casting but also can be matched with ceramic rollers, marble rollers, etc., with the cooling device of the three-roll mill, which can quickly cool the heat generated during work. Processing, to achieve the continuity of the three-roll mill work, but also to ensure the material in the process of grinding, color difference, or damage.

The roller shaft of the three-roll mill mainly affects the fineness of material grinding, and the user can choose manual adjustment and a PLC control system. The manual adjustment of the three-roll mill is mainly by adjusting the runner on the body of the three-roll mill, and the PLC control system is very simple, and the problem of grinding fineness can be completed by simply setting the display screen.

The process of roller-grinding material

The raw material is fed by a natural hopper composed of two middle and rear rollers and two baffle plates. The opposite asynchronous rotation of the middle and rear two rollers causes the sharp friction and flipping of the raw material, and the strong external shear force destroys the molecules in the raw material particles. structural stress. It is then subjected to high-speed secondary grinding by the middle and front two rollers, to achieve rapid pulverization and dispersion, and then achieve a high degree of uniform mixing of various raw materials.

The working process of the three-roll mill

When using a three-roll mill, the user needs to adjust the gap between the middle and rear rolls to 0.3 mm, and press the baffle plate. Then, the roller shaft of the three-roll mill is properly added to the slurry, and the coloring depth is visually inspected. After fine-tuning the rear roller, the coloring is evenly distributed on the roller, and then the fixing nut is locked.

When adjusting the fineness of the material, the user needs to adjust the hand wheel of the front roller with both hands at the same time, so that the front roller slowly contacts the middle roller. After the surface of the front roller is evenly colored, lock the fixing nut, and then adjust the angle of the material plate to make it press lightly. On the roll surface, the slurry can be discharged evenly. Check the uniformity of the discharge and the particle size of the finished product, and continue to fine-tune the front and rear rollers until the particle size of the finished product reaches the predetermined requirements. The scraper should be returned in time before and after.

Three-roll mill is the most effective grinding and dispersing equipment for high-viscosity materials. Mainly used for the grinding of various paints, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber, and other liquid slurries and paste-like materials.

Three Roll Mill For Grease

The three roll mill plays a vital role in the grinding of grease. Grease is essentially a kind of lubricating oil, which is a solid or semi-solid product formed by one or more thickeners through the grinding and dispersing action of a three roll mill.

Three Roll Mill For Attapulgite | Glue Grinding Equipment

Three roll mill is the main equipment for grinding attapulgite. The attapulgite is ground and dispersed mainly because it is a natural colloid. Even if the size of the attapulgite reaches 0.1mm, it cannot be easily dispersed by the machine, so the final state of attapulgite formation has been greatly developed.
