[Summary] Experiments were conducted to investigate the relationship between the particle size distribution of zeolite and grinding time using D18S. The grinding times were varied at 15 minutes, 30 minutes, 1 hour, 2 hours, and 4 hours, with 2g samples taken at each interval. The particle size distribution of these samples was measured using a laser diffraction particle size analyzer. *The laser diffraction particle size measurement was outsourced to an external organization.

■Overview We examined the possibility of further fine grinding of approximately 100 nm phthalocyanine organic pigments using the D18S type Ishikawa stirring mill with the solvent salt milling method. It was demonstrated through electron microscope images that organic pigments can be fine-ground using the solvent salt milling method with the D18S type Ishikawa stirring mill. ■Discussion Salt milling is a technique that uses fine NaCl particles to grind and refine organic pigments. When organic pigments are refined through salt milling, they also tend to grow again. Ideally, temperature control during the fine grinding process is crucial. It can be concluded that fine grinding of organic pigments is possible using the Ishikawa stirring mill with the salt milling method. By using the Ishikawa stirring mill, it seems feasible to conduct studies on the fine grinding of organic pigments through salt milling on a small scale, with easy cleaning. Models that allow for temperature control of the pot have also been developed by Ishikawa Factory Co., Ltd., and it is believed that they can be applied for research purposes in the fine grinding of organic pigments using the salt milling method on a small scale.

**Summary** The particle size distribution was measured after crushing glass pieces using an automatic mortar AGB. The glass slides, typically used for microscopes, were crushed to about 3.5 mm and then pulverized with the automatic mortar AGB. The grinding time was 5 hours, and the particle size measurement was conducted using a laser diffraction device. **Background and Purpose** To understand the grinding performance of the AGB type Ishikawa stirring mill produced at the Ishikawa factory, the grinding of glass pieces was carried out. **Conclusion** When glass pieces crushed to about 3.5 mm using a microscope slide are pulverized with the AGB type Ishikawa stirring mill, saturation occurs in about 3 hours, achieving a particle size of approximately 1.7 μm.

Generally, when concentrating slurry, decanter centrifuges, thickeners (concentration tanks), and evaporative concentrators are used. However, decanter centrifuges are expensive equipment and take up space. Additionally, due to high operating costs, one must be cautious when considering their introduction. Thickeners may require a long time for concentration depending on the particle size and concentration of the slurry. They are also not suitable for small-scale concentration. To address these challenges, this time we will conduct experimental verification of a concentration method using the Ishikawa-type stirring and grinding machine (automatic mortar) in a small and straightforward manner. Specifically, we will apply air intake and exhaust ports to the film double insulation cover of the automatic mortar, allowing air to be drawn in and expelled, and heat the slurry to about 60°C to verify whether small amounts of slurry can be easily concentrated. In conclusion, it was found that using the automatic mortar D18SEB, with air intake and exhaust ports applied to the film double insulation cover and heating the slurry to about 60°C, small amounts of slurry can be easily concentrated. This could also serve as proof of its potential use as a "slurry-specific evaporator."

【Features】 - The basic performance of the Ishikawa-type stirring and grinding machine remains unchanged, but it has a heating function. - It is a tabletop model with a stainless steel casing, making it ideal for use in laboratories and clean rooms. - By using a stainless steel bowl, it has the ability to transfer heat uniformly and quickly. - It can perform stirring and grinding processes while heating up to 160°C. - It has a transparent acrylic cover, ensuring safety and preventing the scattering of ground materials. - Equipped with an inverter as standard, allowing control of the pestle's rotation speed. 【Suitable Usage Examples】 - It can simultaneously disperse and knead slurries and pastes while concentrating and drying, allowing for fine grinding without solidifying the materials. - During the concentration process of slurries and pastes with added solvents, it achieves uniform dispersion and kneading through the stirring effect of the pestle and the grinding action at the tip of the pestle. - Using mechanochemical and mechanical alloying techniques that cannot be achieved with dedicated machines like stirrers, dispersers, kneaders, and grinders, it enables the synthesis of electronic materials and secondary battery materials. - The Ishikawa-type stirring and grinding machine (Kakuhan Raikai) is a machine capable of simultaneously performing "stirring," "dispersion," "grinding," "mixing," "kneading," "crushing," and "breaking." Its unique structure achieves particle size uniformity and mixing uniformity.
