Description:
The Used Thermal Processing Solutions 36" Indirectly Heated Electric Rotary Calciner is a high-temperature material processing system designed for precise thermal treatment of powders, granules, and specialty materials in metallurgy, ceramics, chemicals, and advanced materials production.
With an RA253MA furnace section, Blanchard ground fixed seal rings, and a 9" thick Fiberfrax insulation system, this electric rotary calciner ensures consistent temperature uniformity up to 1000°C. The SiC ceramic heating elements provide continuous duty performance at 1600°C, while the Watlow PID loop controllers and SCR power panels offer high-precision control over thermal processing conditions.
This system integrates an indirect 24" diameter x 21' convective rotary cooler, allowing for efficient material cooling before packaging or further processing. Designed for controlled heat treatment with minimal contamination risk, this industrial-grade calciner is ideal for advanced material processing applications.
