The working principle of the rotary tube calcining furnace is to generate heat through electric energy heating, and transfer heat to the material through furnace tube
Overview
The working principle of the rotary tube calcining furnace is to generate heat through electric energy heating, and transfer heat to the material through furnace tube, so that the material can undergo biochemical reaction or physical change under high temperature. This equipment is mainly used for calcination of chemical products and metal powders, such as the calcination of ammonium paratungstate to obtain WO3.
Advantages
Our rotary tube calcining furnace has the follow advantages.
① High efficiency: The use of advanced heating technology and efficient heat transfer mode, can achieve rapid heating and calcination of materials, improve production efficiency.
② High output: The equipment structure is reasonable, has a strong heat load capacity and a large heating area, can achieve high output production, energy saving, long service life.
③ Low energy consumption: Adopting technologies of efficient heating and waste heat recovery can reduce energy consumption and improve energy efficiency.
④ The inlet and outlet spiral of the furnace tube adopts frequency conversion main speed regulation to control the output and quality.
⑤ Stable temperature change, accurate control, small error, high product quality.
⑥ This furnace can be adapted to different products and quality.
