A record of real solutions for the three processes of slurry observed through practical verification with cosmetics, ink, and electronic component manufacturers.
In the manufacturing site of slurries (raw materials where powders and particles are dispersed in a liquid), challenges such as "the powder settles or floats even when stirred," "high viscosity prevents it from being removed from the container," and "filtration takes a long time" repeatedly occur. This document is a collection of case studies summarizing data obtained from actual equipment verification using real raw materials before implementation, along with the directions for solutions identified from that data.
The content is structured into three main parts:
1. The foundational column explains how to choose stirrers and mixing devices that are resistant to sedimentation and settling, as well as customization proposals for slurry tanks (seven cases including dispersion, liquid transfer, cooling, explosion-proofing, and filtration).
2. The verification report presents three examples: "stirring a 150L cosmetic slurry with a powder ratio of about 50%," "discharging a high-viscosity slurry with a viscosity of about 150,000 cP (rat hole countermeasures)," and "vacuum filtration of carbon dispersion slurry," including conditions, values, and customer feedback.
3. Information useful for considering implementation is also provided.
This is recommended for those in charge of design, production technology, and quality assurance who want to consider not only "what to mix with" but also "how to input and output" the equipment. We offer customized solutions for each unit, ranging from small volumes for trial use (4L and up) to production use (around 1000L).
