Customization is supported. The boiling roaster, also known as a solid fluidized - bed roaster,
uses air at a certain flow rate to carry out a series of intense
roasting reactions on powdered materials. During the process, the
materials are in a continuous motion state, similar to the boiling
state of a viscous liquid, so it is called a boiling roaster. Furnace TypesGenerally, there are two types of roasters: straight - cylinder
roasters and roasters with an enlarged upper part.- Straight - cylinder roasters: Mostly used for roasting non -
ferrous metal concentrates.
- Roasters with an enlarged upper part: Early on, they were used for
crushing ore lumps (as raw materials for sulfuric acid production).
The roasted sulfur ore is mostly in a blocky shape, so it is also
known as a block - shaped roasting furnace. Later, it was developed
for various types of floatation ores (including non - ferrous metal
floatation concentrates and associated sulfur ores produced during
ore dressing), as well as for roasting sulfur - rich concentrates
obtained through floatation to improve the grade of sulfur - rich
ores. These ores have a relatively small particle size.
Advantages of Boiling Roasters- High production intensity. Due to the close contact between the air
and the materials in the furnace, and the relatively intense
relative movement between the gas flow and the materials, the
reaction is rapid.
- High heat transfer efficiency. The materials boil violently in the
furnace. Coupled with the effect of air, the isolation between
material particles is broken, and the specific surface area
increases. The contact surface per cubic meter can reach 3280 -
49200 m².
- Suitable for a wide range of raw materials, especially for the
rapid roasting of fine - grained materials.
- Simple operation, and easy to achieve mechanized and automated
operation.
