Sealed Grinder

The sealed grinding mill operates by using a motor to drive the rotation of the tank, where grinding media and materials collide and rub against each other to achieve pulverization. It is used for fine grinding of laboratory samples and is suitable for raw material preparation in industries such as coatings and plastics.
Selection
When selecting, consider the hardness of the sample to determine the material of the grinding medium, choose the jar capacity based on the processing volume, configure the speed range according to the fineness requirements, and pay attention to sealing performance to prevent cross-contamination.

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.
Sealing tester measures the pressure resistance and leakage of composite film bags.
This article introduces how to use a seal tester to evaluate the pressure resistance and leakage performance of composite film bags. The test primarily involves applying controlled pressure inside the packaging and observing pressure changes or leakage to assess the quality of the seal.
Positive pressure method seal tester evaluates packaging pressure resistance
This article introduces how the positive pressure method sealing tester evaluates the pressure resistance of packaging. The instrument simulates actual pressure conditions by injecting compressed air into the packaging and then monitors pressure changes to determine if there is any leakage.
Negative pressure method leak detector for testing vacuum packaging seal integrity
The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
