Description

Technical Field

[0001] This utility model relates to the field of material testing and measuring instruments, and in particular to a powder strength testing device. Background Technology

[0002] Powder materials play a vital role in modern industry, especially in fine chemicals, pharmaceuticals, new energy materials (such as lithium-ion batteries), advanced electronic ceramics, and powder metallurgy. To overcome the inherent problems of poor flowability, dust generation, and uneven packing density of micro powders, granulation processes are often used in industry to process them into granular materials. This not only significantly improves the flowability and handling of powders but also enhances the efficiency and stability of subsequent processes.

[0003] However, when using micro-powders from lithium-ion batteries, ceramic capacitors, inductors, and other materials as raw materials, soft granules are often preferred to achieve good formability. Based on experience, the destructive force of soft granulated powder is mostly below 1mN. Therefore, high-resolution testing equipment capable of 100,000 divisions is required. However, in existing technologies, most powder strength measurement devices use the same principle as electronic balances to detect the load, which limits the force resolution. This is because the pressure head and detector structure itself are very heavy, so gravity will act on them as the initial load. The weight of these components will increase the rated capacity, thus seriously affecting the resolution of the equipment. Utility Model Content
