Product Overview
Rotary Tube Furnace for
Powder Calcination
BR-12NRT rotary tube furnace is designed for calcining inorganic compounds with better uniformity. It is especially suitable for R&D laboratories working on lithium-ion battery cathode materials, carbon-coated powders, catalyst powders, ceramic powders and other functional inorganic materials.
Compared with a static horizontal tube furnace, the rotary tube furnace continuously turns the material bed during heating. The quartz tube rotates at adjustable speed, while quartz lifting plates on the inner wall help powders tumble and mix more completely. This improves heating uniformity, gas-solid contact and coating consistency.

How It Works
How the Rotary Tube Furnace Processes Powder
The furnace works by combining controlled heating, tube rotation, powder lifting, adjustable inclination and gas atmosphere flow to improve calcination uniformity and material reaction quality.
Feed Powder
Powder or granules are loaded into the quartz rotary tube manually or through optional feeding accessories.
Rotate Tube
The tube rotates at 0–10 RPM, and internal lifting plates repeatedly turn the material bed.
Controlled Heating
The 50-segment PID controller manages heating, holding and cooling curves accurately.
Gas Contact
Optional gas flow or vacuum system supports air, inert gas or controlled atmosphere processes.
Collect Material
After processing, material can be discharged by tilt angle adjustment or collected through optional discharge parts.
