What is a continuous feed rotary tube furnace?

Continuous feeding rotary tube furnace is a specialized equipment for high-temperature heat treatment, widely used in industries such as powder metallurgy, ceramics, refractory materials, lithium positive and negative electrode materials, and new energy. The following is a detailed introduction to the continuous feeding rotary tube furnace:
1. Definition and Characteristics
Definition: A continuous feeding rotary tube furnace is a device that can continuously and uniformly feed materials into the furnace and perform high-temperature roasting treatment during the rotation of the furnace tubes.
characteristic:
Continuous feeding: using spiral or other continuous feeding methods to ensure that materials can enter the furnace continuously and stably.
Rotating design: The furnace tube can rotate 360 degrees, allowing the material to be uniformly heated in the furnace, improving heating efficiency and product quality.
Adjustable: The inclination angle of the furnace body and the rotation speed of the furnace tube can be adjusted to meet the processing needs of different materials.
Efficient and energy-saving: The furnace adopts high-quality insulation materials to reduce heat loss and improve energy utilization efficiency.
2. Working principle
The working principle of a continuous feed rotary tube furnace mainly includes the following aspects:
Feeding system: The material is uniformly and continuously fed into the furnace through a spiral or other continuous feeding device.
Heating system: Heating elements (such as silicon carbon rods, silicon molybdenum rods, or resistance wires) are installed in the furnace, and the temperature is controlled by a temperature controller to achieve the desired high temperature environment in the furnace.
Rotating system: The furnace tube is driven by a motor to rotate, allowing the material to be uniformly heated inside the furnace. Meanwhile, the inclination angle of the furnace body and the rotation speed of the furnace tube can be adjusted as needed.
Discharge system: After high-temperature roasting, the material is discharged from the other end of the furnace to complete the entire processing process.
3. Application Fields
Continuous feeding rotary tube furnace has a wide range of applications in multiple fields, mainly including:
Ceramic industry: used in the firing process of ceramic products, such as tiles, sanitary ceramics, etc.
