The SLIM is a rotor/stator device engineered for high-speed powder injection into liquid without the need for eductors or pumps. The improved hopper design ensures a steady rate of feed delivery and prevents "rat holes” or bridging of bulk solids. Typical solids dispersed include fumed silica, CMC, carbon black, graphite, talc,  titanium dioxide, calcium carbonate, clays, alumina, carbomers, dye powders and other additives or fillers.

Mix chamber is equipped with a modulating valve

Shown is a "30HP inline SLIM Mixer" with a 6 cu.-ft. conical feed hopper featuring multiple air jets and three level transmitters to automatically indicate high (powder feed off), low (powder feed on) and low-low (SLIM induction valve off). The mix chamber is equipped with a solenoid-operated multi-position modulating valve for maintaining a liquid flow rate within 80% to 100% of the 500 gpm design flow rate.

All product contact parts are stainless steel 316 polished to 150-grit (32 Ra) finish. Tri-clamp connections on the liquid inlet, powder inlet and mixture outlet allow for easy disassembly and cleaning. The mixer is supplied with a cartridge-type double mechanical seal and barrier fluid tank.
