The EXAKT 120EH-250 Three Roll Mill

EXAKT 120E-250 w Hopper Close

The EXAKT 120E provides higher productivity and more power with the same precision as the 80E Plus. This makes it the ideal equipment for a scale-up when higher production volumes are required. Continuously excellent results for particle fineness down to 1 μm and stable production conditions. This mill has proven its worth wherever maximum reproducibility and control are required. This model is found in laboratory and production environments.

  • Achievable fineness of less than 1 μm
  • Gap or power mode optionally selectable per gap
  • One-pass calibration – automatic adjustment of the spacing and parallelism of the rollers
  • Electronic display of all operating parameters
  • DataLog – documentation of processing parameters
  • Throughput up to 14 l/h with a gap width of 5 μm
  • Roller temperature control for optimum process control
  • Safe working – overload protection, cleaning, and reverse mode
  • Scraper knife angle adjustable

The EXAKT 80E Plus Three Roll Mill

The 80E PLUS three roll mill delivers faster-dispersing results with real-time process analysis. By combining high-precision mechanical design with a state-of-the-art electronic control system, EXAKT has created the new standard for three roll mill technology.

Users will have more information than ever before, and the ability to make adjustments on the go.

  • Safe operation mode for the cleaning process
  • Numeric or graphical real-time presentation of all relevant production parameters
  • Easy to use data transfer via USB interface
  • Gap Mode: Adjustable gap size from 5 to 180 μm
  • Force Mode: Line pressure adjustable up to max. 26 N/mm, depending on working width
  • Variable throughput from as little as 10 ml up to 18 l/h at a 10 μm gap
  • Roller materials chrome, tungsten carbide, aluminum oxide or silicon carbide

Three Roll Mill Advantages

Three roll mill advantages

Only the three roll mill used in the dispersing process guarantees that 100% of the product will be passed through both shear zones.

  • The shear rate between the rollers is the decisive factor for the process.
  • This is determined by the roller spacing and the circumferential speed.
  • Agglomerates and powder clumps are broken up and homogenized.
  • The more controlled the energy input, the more precise the processing.

The EXAKT 80S Plus

The new EXAKT 80S PLUS has higher safety standards, easier operation, and an even more precise adjustment of the gap. With a powerful motor, optional temperature control and the choice of ceramic and metallic rollers, the new 80S Plus was designed for processing a wide range of different materials.

This three roll mill works well with both small quantities in the laboratory or larger production quantities. Different working widths and exceptional safety devices ensure ideal working conditions for many products.EXAKT 80S Plus

  • Easily monitor speed, temperature, production timer, and power consumption on the color display
  • Adjustable gap range: 5 to 230 μm
  • Variable throughput from as little as 10 ml up to 18 l/h at a 10 μm gap
  • Covers made of stainless steel, blasted or optional electro-polished
  • Roller materials: Chrome, tungsten carbide, aluminum oxide or silicon carbide
  • Meets or exceeds safety standards specified in ANSI

EXAKT 50I Three Roll Mill

50I Horizontal TRM ebrochure

The EXAKT 50 I Three Roll Mill is an especially compact, versatile and easy-to-operate unit for applications where excellent dispersing is essential. Working with separate roller sets is particularly effective in regard to fast cleaning, the avoidance of cross-contamination and downtimes due to changing the product. EXAKT 50 is indispensable for research, development, and training.

  • Roller gap to 10 μm
  • Precise setting of the roller gap, no dry running possible
  • Up to 5 l/h throughput with a gap width of 10 μm
  • Continuously adjustable circumferential speed of the rollers
  • Interchangeable roller set
  • Ceramic or hardened chrome rollers
  • Precise one-hand adjustment, continuous and with scale
  • Self-adjusting scraper knife
  • Overload protection

EXAKT Three Roll Mills for Carbon Applications

EXAKT Three Roll Mills for CNT

Why should you be using an EXAKT three roll mill for your carbon application? Some of the process advantages include:

  • Disperse the difficult – tangled CNT, especially in viscous pastes such as Epoxy and Silicone.
  • Exfoliate graphite-based materials without destroying the plate-like structure.
  • Control the level of dispersion.

EXAKT’s electronic models (80E Plus, and 120E) give the most precise control and repeatability.
