Product introduction

    1.Introduction of roaster equipment


   Roasting furnace is a kind of equipment for high-temperature heating treatment of powdery or cake-like materials. It is also called calcining furnace. According to the energy used, it can be divided into four types: coal burning furnace, gas furnace, oil furnace and electric heating furnace. ; Divided into two types of direct heating and indirect heating according to the heating method; divided into two types of continuous operation and intermittent operation according to the operation method. Roasting furnace is mainly used in the process of activation, crystal transformation, oxidation, pyrolysis, reduction, halogenation, sulfate and other processes, and is widely used in the production of special materials in the petrochemical, inorganic chemical, metallurgical, and construction industries.

   When the indirect heating continuous operation type roaster works, the material enters the furnace barrel through the furnace head feeder. The heating furnace is equipped with an electric heating element or a fuel burner. The automatic control system adjusts the current of the electric heating element or the flame of the burner to control the furnace temperature. , So that the material is roasted at a certain temperature. Stove operation is horizontal or inclined. The material is roasted in the furnace while moving forward while the furnace rotates, and the material after firing enters the next process from the discharge end. The roasting time of the material can be controlled by adjusting the speed of the furnace drum or the angle between the furnace drum and the horizontal.

Electric heating roaster uses electricity as energy source. It is mainly composed of the main body of the roaster, the electric heating system, the holding furnace, and the automatic control system. In addition to the conventional rotary-cylinder roasting furnaces developed by our company, there are also special-type roasting furnaces for special materials such as vacuum type, positive pressure type, and double cone rotary type.

   The gas-fired roaster is mainly composed of the main body of the roaster, the combustion device, the heat preservation furnace, the ventilation and exhaust device, and the automatic control system. Combustible gases such as natural gas, water gas and liquefied petroleum gas are used as fuels, which have sufficient combustion and high thermal efficiency. At the same time, the combustion process is easy to control, and the solid and liquid fuels have less pollution to the environment.

   Second, the characteristics of electric heating roaster

Fourth, specifications and models


Five, application range

The roasting furnace is widely used in the roasting of special materials (such as special catalysts, special molecular sieves, kaolin, mineral powder, special adsorbents, inorganic salts, etc.) in the petrochemical, inorganic chemical, metallurgical, and construction industries. Main application examples: oil refining catalyst, zeolite molecular sieve, activated carbon adsorbent, magnetic materials, sulfide ore, manganese ore, soda ash, aluminum hydroxide, refractories, silicate, ceramics and other materials.
