Types & functions of three-roll mills

Three Roll Mill

The three-roll mill can be used in a wide range of applications, not only for grinding and dispersing factory materials but also for research in scientific research units and laboratories.

Details of Three Roll Mill

  • Two types: handwheel and digital control gap
  • Safe scraper socket, Emergency-stop
  • Space-saving desktop models
  • Drip tray for easy cleaning

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

Due to the different grinding objects, the required machines are also slightly different, which not only depends on the material of the roller shaft of the three-roll mill but also includes the operation method, grinding effect, heating state, hydraulic effect, etc. FRANLI is a professional three-roll mill. Roll mill manufacturers, according to the needs of different users, finely classify three-roll mills, including laboratory three-roll mills, manual three-roll mills, hydraulic three-roll mills, heating three-roll mills, strong Type three-roll mills, etc.

Laboratory three-roll mill

A laboratory three-roll mill is a small machine, which is mainly used for research in scientific research units, laboratories, and university studios. Some factories also use laboratory three-roll mills for small-scale production. It can be equipped with a PLC control system to collect corresponding parameters, and a circulating cooling water tank with an automatic cooling device can also be selected to solve the troublesome installation of cooling water pipes and difficult drainage for users and maximize its practicality. The final fineness of the laboratory three-roll mill can reach 1 micron, which mainly depends on the characteristics of the material itself. The user can easily adjust the distance between the rollers and the final grinding state through the PLC control system.

Hydraulic three-roll mill

The hydraulic three-roll mill can also be equipped with a PLC control system, and the user can set the formula into the three-roll mill control system in advance. There are many types of hydraulic three-roller machines. According to the horizontal position of the roller shaft, they can be divided into horizontal type, inclined type, and vertical type. Each roller shaft has an independent cooling device, which can effectively control the material in the grinding process. The temperature difference greatly reduces the grinding pressure of ordinary three-roll mills and effectively improves the production efficiency of three-roll mills. Whether it is medium, high, or low viscosity materials, it can be easily ground and dispersed.

Heated three-roll mill

The heated three-roll mill is mainly used for grinding and dispersing high-viscosity materials, such as thermal processing of color masterbatches such as EVA, ABS, PE, PP, PVC, and other rubbers, and effectively disperses some extra-hard materials. Engineers made the whole working process more stable and automatic by enlarging the roller head.

Vertical three-roll mill

The vertical three-roll mill produced by FRANLI has an independent invention patent, and this machine is mainly used for low-viscosity and easy-to-drop powdery materials, such as guar gum, soap grains, Ganoderma spore powder, etc. after The viscosity of the processed materials will be greatly improved. Its structure is different from the traditional three-roll mill, the traditional rollers are all horizontal, but the rollers of this machine are vertical. The material is fed through the uppermost slow roller shaft, firstly ground through the middle and slow shaft, and then secondly ground through the fast shaft to effectively ensure the grinding effect. According to the user’s usage habits, hydraulic type and manual type can be selected. type.

Powerful three-roll mill

It mainly includes new powerful, enhanced, and high-strength three-roll mills. It is mainly designed for grinding materials with high viscosity and high hardness. It can be made into a cooling type or heating type (steam heating, oil heating, etc.) according to the needs of users. It is the best equipment for grinding pigments, pencils, and attapulgite.

Guidelines For Three Roll Mill

Three roll mills are widely used in a variety of chemical industries, from medium to high viscosity productions. FRANLI machine can break open all kinds of pigment, UV ink, offset ink, decorative paints, and Lubricants, it also can catch the greatest fineness in cosmetics/ lipstick and electronics industries.

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

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.

Rolls of a 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.
