High Precision Three Roller Grinding Mill for Process Optimization in Fields Such as Nanoparticle Dispersion/Graphene Slurry Preparation
In the preparation of nanomaterials and two-dimensional materials, such as nanoparticle dispersion and graphene slurry production, traditional processes often face challenges such as uneven dispersion, batch inconsistency, and material structural damage. The high-precision three roller grinding mill, with its precise mechanical design and intelligent control, provides a reliable, efficient, and repeatable process optimization solution for these demanding applications.
Core Advantages:
- Precision: The roller gap repeat positioning accuracy can reach ±1 micron, combined with a wide-range linear load of 5–120 N/mm. It can gently disperse sensitive materials while strongly breaking down difficult-to-grind agglomerates, easily achieving nano-level particle size control.
- Control System: The PLC intelligent control system monitors roller speed, temperature, and pressure in real time, automatically replicating optimal process parameters. This reduces the standard deviation of particle size distribution between batches to within 2 microns, completely solving the challenge of mass production consistency.
- Flexible Adaptation: From low-viscosity nano-slurries to high-viscosity graphene composite materials, all can be adapted through adjustments in roller speed ratios (e.g., 1:3:9) and cooling systems, avoiding high-temperature degradation of materials and preserving the inherent properties of the original particles.
Application and Optimization of ZYE Three Roller Grinding Mill in Graphene Slurry Preparation
Traditional oxidation-reduction methods can easily cause defects in the graphene structure. The high-precision three roller grinding mill employs a controlled liquid-phase exfoliation process, applying massive and uniform shear forces in specific solvents to "gently" exfoliate graphene layers.
- Process Advantages: By optimizing the roller speed ratio and multiple passes, high-quality graphene slurry with fewer layers, low structural defects, and excellent conductive properties can be efficiently prepared.
- Key Technology: The use of a no-crown roller technology ensures uniform force distribution along the entire roller length, achieving efficient and uniform exfoliation and dispersion of graphene, effectively suppressing re-stacking and agglomeration of layers.
- Integrated Process: Combined with vacuum degassing and a clean environment design, graphene slurry with high solid content and low impurities can be prepared, fully meeting the stringent requirements of high-end applications such as conductive coatings and high-performance battery electrodes.

Application and Efficiency of ZYE Three Roller Grinding Mill in Nanoparticle Dispersion
Addressing the stubborn agglomeration issues caused by the high surface energy of nanoparticles, the high-precision three roller grinding mill utilizes its unique multi-stage shear field design and automatic gap calibration process to apply anisotropic high-intensity shear and compression, thoroughly breaking down agglomerates and achieving nanoparticle dispersion in the matrix. This directly enhances the strength, transparency, or optoelectronic properties of composite materials.
Process Optimization
- Laboratory-Scale Testing: Conduct experiments on a small laboratory three roller grinding mill to study the effects of key parameters such as gap, speed ratio, and number of passes, and establish testing methods for critical quality attributes, such as particle size distribution, particle size, and rheology.
- Parameter Standardization and Recording: Establish standard operating procedures for each successful formulation, precisely recording all parameters, including gaps per pass, roller speeds, speed ratios, cooling water temperature, number of passes, and discharge temperature.
- Pilot-Scale Scale-Up: Scale up based on the principles of similar shear rates or similar energy consumption per unit volume. Online viscometers, temperature sensors, and even online particle size analyzers can be integrated to achieve real-time monitoring and feedback.
- Safety and Environmental Protection: For systems involving volatile organic solvents, operations must be conducted in an explosion-proof environment and equipped with solvent recovery devices.
In the wave of advanced material industry upgrading, the high-precision three roller grinding mill breaks through process bottlenecks with technological innovation, becoming the "core equipment" in fields such as nanoparticle dispersion and graphene slurry preparation. Whether pursuing ultimate dispersion effects or requiring stable mass production solutions, it provides customized process support, driving the high-quality development of the high-end materials industry.
