Dependence of Zeolite Particle Distribution on Grinding Time

石川工場 石川工場
**Summary** To understand the performance of the Ishikawa-type mixing and grinding machine produced at the Ishikawa factory, zeolite was used as the standard material to clarify the relationship between grinding time and particle size distribution through experiments. First, experiments were conducted using the D18S (desktop machine) to examine the relationship between the particle size distribution of zeolite and grinding time. The grinding times were varied at 15 minutes, 30 minutes, 1 hour, 2 hours, and 4 hours, with 2g samples taken at each interval. These samples were then analyzed for particle size distribution using a laser diffraction particle size measurement device. **Conclusion** In the particle size distribution, the peak value (mode) was 0.4μm for grinding times up to 1 hour. After 2 hours of grinding, it was 0.1μm. The standard deviation, which represents the variation in particle size, decreased with longer grinding times. However, beyond 2 hours, it saturated and remained almost constant at 3μm. From this, it can be concluded that within the experimental range, the relationship between the particle size distribution of zeolite and grinding time using the D18S shows that longer grinding times result in smaller particle size (mode) and less variation (standard deviation), but after 2 hours, it becomes constant.

Product Information Details for D18S
This is the product information detail page for D18S, which was used to obtain data on the dependence of zeolite particle distribution on grinding time. D18S is a tabletop model equipped with two pestles, fully equipped with the performance of the Ishikawa-type stirring and grinding machine. Its stainless steel casing makes it suitable for physical and chemical experiments. Due to its unique technology, the trajectory of the pestles in the bowl is epicyclic, and the processing energy is lower compared to ball mills, making it suitable for mechanical alloying, mechanochemical, and mechanofusion processing.

Metal Crack Repair: MS Method for Repairing Cracks and Fractures in Machinery Equipment

  • NEW
  • CATALOG

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
