EXAKT Three Roll Mills for Carbon Applications

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.

Whether it’s for research or production, learn more by calling or emailing our three roll mill experts.

EXAKT Dispersion Process

Conventional Mixing vs. EXAKT Milling

Compounding EXAKT

A comparative study conducted at the University of Hamburg, Institute of Pharmacy in Hamburg Germany concluded that the quality of compounds processed with three roll mills is better than those processed with electric mixing systems.

  • Particle size is smaller.
  • Particle size distribution is narrow.
  • Ointment stability is better.
  • Temperatures do not increase significantly during processing.
  • Ointments are softer consistency with lower flow limits
  • Three roll mills allow for quality control during processing.

 

Substance processed with conventional mixing procedure: crystalline substances are still clearly visible.

Substance processed with an EXAKT three roll mill: regular and fine consistency of the substance

EXAKT Results

EXAKT three ointment mills deliver results that are consistent and reproducible.

A comparative study conducted at the University of Hamburg, Institute of Pharmacy in Hamburg, Germany concluded that the quality of ointments processed with three roll mills is better than those processed with electric mixing systems. The study highlighted the following conclusions:

  • The particle size is smaller.
  • Particle size distribution is narrow.
  • Ointment stability is better.
  • Temperatures do not increase significantly during processing.
  • Ointments are softer consistency with lower flow limits.
  • Ointment mills allow for quality control during processing.

Ointment Mill Advantages

Three roll mill advantages

Only the ointment 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 120EH-450 Three Roll Mill

The EXAKT 120EH-450 is the highest performance three roll mill of the E-Line series. Developed for production, the mill offers options for the automatic filling, monitoring, and cooling. The electronic control concept enables the precise setting of all relevant processing parameters. Recurrent production processes can also be programmed and all operating parameters continuously stored. This means they are available at any time for documentation or for subsequent analysis of the results. Reproducible, consistent and documented quality is the precondition for efficient production.

  • 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 or 27.5 l/h with a gap width of 5 μm
  • Roller temperature control for optimum process control
  • Safe working – overload protection, cleaning and reverse mode
  • Scale-up from the laboratory to production

The EXAKT 120S-450 Three Roll Mill

The EXAT 120S-450 offers continuously good results at particle fineness down to 5 μm. When increased volume and simple handling are required, the120S-450 is the best choice. The process conditions are very easily adapted to the product to be processed. A continuously adjustable processing speed, excellent temperature control, and alternative roller materials provide the best prerequisites for a multitude of material requirements. The compact desktop model is found everywhere in production. The solid processing of the machine provides absolutely parallel, manually adjusted roller gaps for uniform processing.
