Product Description

External Heating Rotary Kiln

The External Heating Rotary Kiln developed by Shanghai Yingyong Machinery Co Ltd (SYM) is a high-temperature processing equipment designed for applications requiring indirect heating. Heat is applied to the outer surface of the rotary tube, allowing precise temperature control and preventing direct contact between the flame and materials. This system is ideal for lithium ore calcination, hazardous waste disposal, and materials that are sensitive to combustion gases or oxidation.

Applications

Lithium ore (spodumene) calcination
Battery material preparation
Hazardous and medical waste treatment
Rare earth and metal oxide roasting
Activated carbon regeneration
Petrochemical catalyst processing
