An Effective Mixing for Lithium Ion Battery Slurries
In the present study, a new three-dimensional mixing device was designed for electrode slurry mixing. The performance of the mixing device was examined initially by a flow visualization technique using clear solutions with a tracer. The effectiveness of mixing anode and cathode materials was then examined rheologically through
TIP: Mixing Vermiculite Concrete - Forno Bravo Forum: The
Apr 12, 2008· The solution is to make a slurry of the Portland cement in water before mixing into the vermiculite. I fill a 5 gallon bucket about 2/3 full of the cement powder, then almost fill to the top with water. Then take a drill-mixer (pictured), and get all the cement suspended into the water. Then pour it into the moist vermiculite.
Perlite or Vermiculite? (rocket stoves forum at permies)
In general, expanded perlite is a little bit better as far as insulation goes. When you use exfoliated vermiculite in a dry state it would be fine as well. In case you want the insulation to be rigid through mixing with clay slip, use perlite, this won't take up as much water as vermiculite.
Vermiculite Concrete Introduction Vermiculite concrete is a low density non-structural construction product. It is insulating (both thermally and acoustically) and intrinsically fire resistant. It is normally made simply by mixing exfoliated vermiculite as the aggregate, with cement and water, plus additives such as plasticisers if required.
Bo's Easy Cement Mixes For Ferrocement and Concrete

Can we use sand instead of vermiculite? - Quora
If you use vermiculite partly to increase aeration, then no, sand will not provide as much. Very coarse sand will provide some aeration, but not as much water retention, so it really depends on what your soil lacks. Substitutes for vermiculite mig
Ultrasonically Accelerated Gypsum Crystallization
Ultrasonic mixing and dispersing accelerates the crystallization and setting reaction of gypsum (CaSO 4 ･2H 2 O). Application of power ultrasonics to the gypsum slurry accelerates crystallization thereby reducing the setting time. Besides a faster setting, the produced wall boards exhibit a reduced density.
Continuous-Flow Tubular Crystallization in Slugs
radial jet mixer by mixing hot and cold solutions. The slurry stream containing nuclei acting as seed crystals are combined with an air stream at ﬂow rates selected to spontaneously form stable slugs. The motion of the slug through the tube mixes the solution without requiring any of the stirring blades that cause attrition in mixed-tank

Perlite vs Vermiculite: Differences (and When To Use Them
Perlite, on the other hand, is a specific type of solidified magma (high silica content), also called volcanic glass.Such raw material is turned in the perlite you find at the gardening shop by heating it up at more than 1500F (815C). This, in the same way of vermiculite, will cause the (relatively high) water content in this rock to evaporate, leaving empty pockets inside perlite when it
