Applications
Laboratory rotary furnace is an ideal furnace for the laboratory calcination and drying tasks of positive and negative electrode materials of lithium ion batteries (aluminum ferric phosphate, lithium manganate, lithium cobalate, ternary, graphite cathode, etc.) .
Rotary furnace is also can be used for the high temperature reaction, heat treatment, carbonization,sintering, and high temperature pyrolysis for the rare earth materials, chemical catalytic materials, magnetic materials, powder metallurgy materials, nonferrous metal materials and powder or granular materials of kaolin non-metallic mineral materials, etc.
Based on the tube furnace, laboratory rotary furnace has been added the functions of furnace tube rotating and tilting , the rotating speed is stepless speed regulated, tilting angle can be regulated as while;
In order to prevent material hardening and uneven heated in the smooth tube, lifting plates can be added inside the furnace tube, middle big belly type furnace tube can also be designed to improve the heating result.
Due to the excellent sealing technology, rotary tube furnace can work under both the vacuum and controlled atmosphere environment.

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
