The EXAKT 80 Three-Roll Mill is a laboratory and pilot-scale dispersion and homogenization machine manufactured by EXAKT Apparatebau, Norderstedt, Germany. The equipment shown in the photograph carries the original EXAKT Apparatebau identification plate and is marked Made in Germany. EXAKT three-roll mills are designed for intensive dispersion, homogenization, fine grinding, and de-aeration of pasty materials.

The EXAKT 80 belongs to the company's established three-roll mill range and is suitable for processing materials where controlled shear and particle-size reduction are required. The three-roll principle passes material through controlled gaps between rotating rollers, allowing agglomerates to be broken down and the material to be progressively homogenized. EXAKT identifies three-roll mills as equipment for applications including pharmaceuticals, cosmetics, electronics, printing inks, ceramics, dental materials, food products, greases, and ointments.

The photographed machine has a heavy-duty green EXAKT housing and an electrical identification plate showing 3 × 400 V, 50 Hz. The plate also appears to indicate approximately 1.1 kW power, although some characters on the plate are partially worn and should be verified against the original electrical documentation before installation.

The unit shows visible cosmetic wear, scratches, discoloration, and signs of previous industrial/laboratory use. The photograph is a close-up of the machine housing and identification plate, so the condition and completeness of the rollers, scraper assembly, controls, guards, and other operating components should be confirmed separately.

Applications

The EXAKT 80 Three-Roll Mill is designed for the dispersion, homogenization, fine grinding, and de-aeration of pasty and viscous materials. Three-roll mills are commonly used when high shear forces are required to break up agglomerates and obtain a uniform dispersion. Research applications have used the EXAKT 80E for homogenizing and dispersing nanoparticle-containing pastes and polymer-based materials.

Typical applications include pharmaceutical and cosmetic formulations, ointments, printing inks, electronic pastes, ceramic materials, dental compounds, pigments, coatings, greases, and other viscous formulations. The EXAKT three-roll mill range is also used in research and development and small-scale production environments where controlled dispersion and reproducibility are important.

Technical Specifications

*Published EXAKT three-roll-mill documentation lists the EXAKT 80 with approximately 0.02–20 L/h throughput, approximately 70 kg weight, 650 × 550 × 530 mm dimensions, and 3 × 400 V / 50 Hz supply. The documentation also lists a 1.1 kW speed-control motor configuration for the EXAKT 80. Exact specifications may vary with the machine's roller, motor, scraper and control configuration.

Benefits of Refurbished Laboratory Equipment

Purchasing a refurbished EXAKT 80 Three-Roll Mill can provide laboratories and formulation facilities with access to professional dispersion and homogenization equipment at a lower acquisition cost than purchasing new machinery. The robust three-roll design is particularly useful for applications requiring controlled shear, particle-size reduction, and uniform distribution of solids throughout viscous formulations.

Refurbished EXAKT equipment can be valuable for pharmaceutical, cosmetic, dental, electronics, ceramics, coatings, printing-ink, research, and materials-development laboratories. Existing compatible rollers, scrapers, cooling systems, and accessories may also increase the versatility of the machine depending on their condition and configuration.

Additional Information

The photographed equipment is identified as an EXAKT Apparatebau machine, and the identification plate shows the manufacturer's Norderstedt, Germany address, electrical rating, and Made in Germany designation. EXAKT has manufactured laboratory and industrial processing equipment in Norderstedt for decades and currently offers three-roll mills for research, development, and production applications.

The exact model designation and electrical details should be confirmed from the complete identification plate because portions of the plate are worn in the photograph. The image does not show the complete roller assembly, scraper system, control panel, guards, or accessories. Motor operation, roller condition, roller-gap adjustment, electrical safety, grounding, and emergency-stop functionality should therefore be verified before commissioning.
