No. 7 Heating/Cooling Compatible Ishikawa Type Stirring and Grinding Machine for Crushing and Dispersion
Ishikawa-type stirring and grinding machine No. 7 series, double kettle type with heating and cooling capabilities.
Equipped with a double boiler (jacket) for heating/cooling in porcelain bowls (mortar) and metal pots. Simultaneous processing of grinding (crushing, disintegration), dispersion, kneading, concentration, and drying operations.
**Features** - Capable of processing while heating and cooling, maintaining the characteristics of the Ishikawa-style stirring and grinding machine. - 7A Processing volume: 20L, 7AA Processing volume: 60L, 7B Processing volume: 100L, 7C Processing volume: 150L. - Depending on the processing material, the bowl material can be selected (metal, porcelain). *Note: Porcelain bowls are available for 7A to 7B only. - A mechanism that forces the pestle to rotate can be selected to enhance the grinding function. *Note: For porcelain bowls/porcelain pestles, only free rotation is available. - The material for metal bowls can be selected from bronze, cast iron, or stainless steel. - The outer side of the bowl features a jacket structure, allowing for heating and cooling using an external heat source. **Suitable Use Cases** - Finely grinding slurries, pastes, and colloids without solidifying the material while dispersing and kneading. - Achieving uniform dispersion and kneading during the concentration process of slurries and pastes with added solvents through the stirring effect of the pestle and the grinding action of the pestle tip. - Utilizing the dehydration effect of heating to simultaneously grind and break down powder particles, as well as drying moisture from hydrates. - Mechanical-chemical reactions occur during grinding. Furthermore, heating can accelerate these mechanical-chemical reactions.

Company information
Our company is a specialized manufacturer of mixing and grinding machines. The feature of the Ishikawa-type mixing and grinding machine is that it can simultaneously perform "mixing," "grinding," "blending," and "kneading" in one device, allowing for synergistic effects. Mixing and grinding means performing crushing processes (milling, crushing, mechanical alloying, mechanochemical reactions) and mixing processes simultaneously. With a unique design, it achieves an ideal grinding trajectory, making it a unique machine capable of uniform mixing and grinding processing. 1. Mixing and Grinding (Basic Function) ★ Applications include dewatering of alloys and hydrates, artificial bones, artificial teeth, salt milling (nano-dispersion of organic pigments), chemicals, ceramic grinding, grinding wheels, metal pastes, CNT adhesives, ointments, soba noodle making, particle surface treatment, and more. New functions can be realized by adding the following additional features. 2. Temperature: ★ High-temperature kneading for semiconductor heat sinks and 3D printer resins. 3. Temperature & Vacuum: ★ Evaporator for slurries. ★ Substitute for spray dryers at laboratory levels. ★ Freeze-drying (not only freeze-drying functions but also rapid powdering). 4. Isolation and Sealing: ★ The tabletop model from Ishikawa Co., Ltd. features an acrylic cover that prevents dust dispersion during mixing and grinding.
