[Case Study] Ishikawa-style Automatic Mortar: Application to Salt Milling Method
Ishikawa-style automatic mortar D18S
Grinding and refining organic pigments using NaCl!
■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.

Company information
Our company is a specialized manufacturer of automatic mortar and pestle machines. The features of the automatic mortar and pestle (Ishikawa-style stirring and grinding machine) include the ability to simultaneously perform stirring, grinding, mixing, and kneading using unique technology. It has the following basic capabilities: 1. Uniform and precise mixing is possible - Allows for uniform mixing while controlling particle size. 2. Easy uniformity and control of particle size - Can achieve uniform particle size while finely grinding. 3. Prevents excessive deterioration of materials - Due to low mechanical stress (mild processing energy), it can process while suppressing over-grinding and chemical changes. - High-energy processing (such as ball mills) can cause reaction changes due to heat generation, but temperature management is easier with the automatic mortar and pestle. 4. Suitable for small-scale prototyping and experiments - Ball mills and planetary mixers require large amounts of raw materials, but the automatic mortar and pestle can prototype with a minimum of 0.5g. - Easily adaptable for process scale-up (easy application from small to large scale). 5. Capable of processing slurries, pastes, and high-viscosity materials - The motor torque for the pestle rotation is high, allowing for processing of high-viscosity materials.
