Grind Kwai

A high-speed disperser is a laboratory dispersion and grinding equipment that generates shear force through a high-speed rotating grinding disc, causing material particles to circulate, collide, and break within the container. It is used in industries such as coatings and inks to rapidly reduce particle fineness and enhance product uniformity. It is suitable for small-batch sample preparation and quality control processes in laboratories.
Selection
When selecting a grinding machine, consider matching the motor power with the material viscosity, determine the grinding tank volume based on the sample capacity, and choose zirconia or stainless steel grinding media according to particle size requirements. Pay attention to heat dissipation performance for extended operation, check the sealing design to prevent leakage, and compare the suitability of different tooth-shaped grinding discs for specific materials.

Selection of laboratory grinders is based on the fineness requirements of coatings, choosing between ball mills or sand mills.
The selection of a laboratory grinder should be based on the fineness requirements of the coating. A fineness greater than 50 microns indicates coarse dispersion, 10 to 50 microns is considered medium fineness, and less than 10 microns requires high fineness dispersion.
Mill Selection: Grinding Media and Material Fineness Targets
This article introduces how to select appropriate grinding media based on material characteristics and target fineness during the selection of a grinder.
How to Match the Selection of Fineness Gauge with Grinding Process Requirements
The fineness gauge is used to measure the particle dispersion of materials such as slurries and coatings, reflecting the particle size distribution through the depth of grooves on its surface.
Process of Three-Roll Mill for Handling High-Viscosity Inks
This article introduces the process of using a three-roll mill to handle high-viscosity inks. It first explains that the equipment utilizes three rollers rotating at different speeds to grind materials through shearing and squeezing actions, making it suitable for high-viscosity systems.
Blue-style grinder achieves efficient grinding of ink fineness.
The basket mill is a type of wet grinding equipment used in fine chemical fields such as ink production. It utilizes a high-speed rotating impeller to drive grinding media, generating shear and impact forces on the slurry, thereby dispersing pigment particles and reducing their fineness.
