Oxidizing Sulfatizing Fluidised Bed Incineration Volatilizing Roasts Fluidised Bed Incineration

fluidized-bed roasting of can be used for oxidizing, sulfatizing, and volatilizing roasts

The boiling roaster is also called a solid fluidized roaster, which uses a powdery material to carry out a series of intense calcination reactions under a certain flow of air, between a stationary fixed bed and an air transport bed. During the roasting process, the material is in a state of constant

motion - a state similar to the boiling of a viscous liquid, and is therefore called a boiling roaster.

The furnace type is generally divided into two types: a straight type furnace and an upper enlarged type furnace: a straight type furnace. It is mostly used for the roasting of non-ferrous metal concentrates. The calcination intensity is low, the upper part of the furnace is not enlarged or slightly enlarged, and the appearance is basically cylindrical. 2 upper enlarged furnace. It was used in the early stage for the roasting of crishea of oilohtlyByrite produced as a raw material for the production of suliuric acid, which is mosly in the form of a block, customary calla tump bfs). Lalee18 0h8 developed into a variety of flotation concentrates (including non-ferrous metal flotation concentrates, tailings of sulphur-containing tron brd was

products during beneficiation, and sulfur concentrates obtained by flotation in order to improve the pyrite grade). The calcination of the ofe is vedy smdn and the calcination intensity is high.

Boiling roasters have the following advantages:

1.High production intensity. Due to the close contact between the air and the material in the furnace, the relative motion between the airlow and the material is severe, the reaction is fast, and the production intensity per unit area is high.

2.The heat and mass transfer efficiency is high and the reaction speed is fast. The material boils vigorously in the furnace, and the action of air destroys the barrier between the particles of the material, and the specific surface area increases, and the contact surface per cubic meter can reach 3280-49200m²;

3.A wide range of applicable raw materials. It is especially suitable for rapid calcination of fine material.

4.the operation is simple, easy to achieve mechanization, automated operation.

Henan Zoomline Machinery Manufacturing co. Ltd is located in Wen County, Jiaozuo City, Henan Province. It is mainly engaged in the production and installation of mining equipment and building materials equipment, as well as the relevant process design, equipment production and installation of harmless treatment of industrial waste. Many senior executives and engineers of the company have accumulated a large amount of industrial solid waste, such as fly ash, chromium slag (chromium mud), papermaking white mud, carbide slag, smelting waste slag, coal gangue, pyrite slag, industrial sludge, construction waste and other industrial solid waste treatment front-line practical experience over the years. In recent years, it has cooperated with many research institutes, colleges and universities and technical researchers from all walks of life to learn from each other's strengths and weaknesses, so that our company has made significant improvements in process technology and project construction experience in multiple sub-sectors.

Based on the deep cultivation of traditional R&D, production, manufacturing and sales, our company has fully explored the needs of customers in three dimensions: quality, efficiency and price in recent years.
