Powder grinder

A powder grinder uses high-speed rotating grinding discs or balls to impact and shear materials, breaking solid particles into fine powder. It is used for the grinding and processing of raw materials in industries such as coatings and plastics, ensuring the powder reaches the required fineness for subsequent use.
Selection
Select the grinding disc material based on the hardness of the material: use impact-type for brittle materials and shear-type for tough materials. Match the motor power according to the production capacity, and choose the sieve mesh aperture based on the fineness requirements. Consider explosion-proof needs and heat dissipation performance, and check the replacement frequency of wear parts.

Articles

High-temperature viscometer measures the flow behavior of powder coatings in the molten state.
This article introduces the use of a high-temperature viscometer to measure the flow behavior of powder coatings in their molten state. Powder coatings need to melt and flow before curing, a process that directly affects the smoothness and performance of the coating.
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.
Hall flowmeter measures the flowability of spray powder
This article introduces how a Hall flowmeter measures the flowability of spray powder. It uses a standard funnel to measure the time required for a certain mass of powder to flow out under gravity—the shorter the time, the better the flowability.
Tap density tester evaluates the accumulation characteristics of sprayed powder.
This article introduces how to use a tap density tester to evaluate the packing characteristics of spray powders. The tap density tester simulates vibration to densely pack the powder and measures the mass per unit volume, thereby obtaining the tap density.
Laser particle size analyzer measures the particle size distribution of spray powder.
Laser particle size analyzers measure the particle size distribution of sprayed powder based on the principle of light scattering, which is critical for coating uniformity and adhesion. During measurement, the powder must be dispersed in a suitable medium to avoid agglomeration, and tests should be repeated to ensure accuracy.
Sand Falling Test Apparatus for Measuring the Wear Resistance of Powder Coatings
The sand falling test instrument determines the wear resistance of powder coatings by simulating sand particle impact. During the test, abrasive material falls vertically from a specified height, continuously scouring the coating until the substrate is exposed. The wear resistance is evaluated based on the mass of abrasive material consumed.
