We offer a 4" diameter, electrically heated, fluidized reactor for pilot plant or small commercial installations in the mineral, chemical, and industrial fields. Typical applications include the calcination of ores and concentrates, incineration of carbonaceous fuels and waste (liquid or solid) and chemical conversions or decompositions.

Standard construction is of stainless steel 316. Temperature range for this material is 950° C for most gas compositions except chlorine. Other materials of construction are available to suit special applications. This design and size of reactor is ideal for the development of temperature, atmosphere, and retention time and fluidization velocity parameters for scale-up to commercial installations. Minus 20-mesh, dry and granular material is fed with the fine feeder arrangement into the fluidization gas flow stream. A coarse feeder arrangement is available for other materials.
