basic information
【Specifications】 - Equipment Specifications Height: 1360mm Width: 610mm Depth: 610mm - Bowl Specifications Type: Dedicated bowl for 18ZDEB Contents: Porcelain bowl covered with a copper outer pot Inner diameter: 152mm Depth: 84mm Processing volume: 0.5ℓ 【Functions】 - Vacuum Function (with differential pressure gauge) Crushing (depending on the material being crushed, gas may be generated. In such cases, please install a cooling trap device between the vacuum pump and the equipment to minimize the degradation of the vacuum pump. We can also sell it with a cooling trap included.) - Crushing Function Crushing time and pestle rotation speed can be set. - Heater Function Heat source is a rubber heater. Maximum set temperature is 120℃. The temperature of the bowl can be measured with a thermocouple. Includes over-temperature warning function for emergencies. If the temperature exceeds a certain level, the heater power will turn off, the warning light will illuminate, and the warning buzzer will sound, using a temperature sensor separate from the thermocouple for heater control. - Other Functions Processing status confirmation windows are installed on both sides of the vacuum cover. Equipped with LED lighting for process confirmation. Safety device that prevents the pestle from rotating if the vacuum door is not closed.

Applications/Examples of results
- Slurries, pastes, and colloids can be concentrated and dried while being dispersed and kneaded, allowing for fine grinding without solidifying the materials. - The stirring effect of the pestle and the grinding action of the pestle tip during the concentration process of slurries and pastes with added solvents achieve uniform dispersion and kneading treatment. - Utilizing the dehydration effect of vacuum, it simultaneously crushes and breaks down the particles of the powder, making it possible to remove moisture from hydrates and dry them. This is also suitable for processing materials that are sensitive to moisture. - Concentration, drying, defoaming, and stirring and grinding treatment (simultaneous processing of stirring, grinding, kneading, dispersion, and mixing) can be performed in a vacuum/reduced pressure atmosphere or an inert gas replacement atmosphere such as argon or nitrogen, making it suitable for processing anaerobic (oxygen-sensitive) materials. - When used in conjunction with a cooling trap device, it also functions as an evaporator. Using the mechanical alloying described below, it is possible to synthesize electronic materials and secondary battery materials. This machine can perform "stirring," "dispersion," "grinding," "mixing," "kneading," "crushing," and "breaking" simultaneously, achieving processing effects similar to mechanochemical and mechanical alloying that cannot be realized by dedicated machines such as stirrers, dispersers, kneaders, and grinders. With its unique structure, it achieves particle size uniformity and mixing uniformity.

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.
