China HZP Series Direct Heating Rotary Drum Dryer - Leading Suppliers & Factory for High-Temperature Processing Equipment

The baking kiln, also known as a calcination kiln, is an essential device for the high-temperature heating treatment of powdered or filter cake materials. In China, leading suppliers and factories offer various types of baking kilns tailored to meet specific industrial needs. These can be categorized based on energy sources into electric heating and natural gas heating furnaces. Additionally, they are classified by heating methods into direct heating and indirect heating options, as well as by operation modes into continuous operation and batch processing. Baking kilns play a crucial role in processes such as activation, crystal transformation, oxidation, pyrolysis, reduction, halogenation, and sulfation. They find extensive application in industries like petrochemicals, inorganic chemicals, metallurgy, and construction, making them indispensable for the production of specialized materials. Discover the best baking kilns from top suppliers and factories in China to enhance your industrial processes.

    Description

    When the indirect heating continuous operation roasting kiln is in operation, the material enters the furnace barrel through the furnace head feeder, and the heating furnace is equipped with electric heating elements or fuel burners. The furnace temperature is controlled by adjusting the current of the electric heating elements or the flame of the burner through an automatic control system, so that the material can be roasted at a certain temperature. Horizontal or inclined during road operation. The material is roasted in the furnace barrel while moving forward under the rotation of the furnace barrel. The roasted material enters the next workstation from the discharge end. The roasting time of materials can be controlled by adjusting the furnace drum speed or the angle between the furnace drum and the horizontal.

    Electric heating roasting kiln uses electricity as energy source. It mainly consists of the main body of the roasting kiln, electric heating system, insulation furnace, automatic control system, etc. The electric heating roasting kiln developed by our company includes not only conventional rotary cylindrical roasting kilns, but also special material specific roasting kilns such as vacuum type, positive pressure type, and double cone rotary type.

    The gas roasting kiln mainly consists of the roasting kiln body, combustion device, insulation furnace, ventilation and smoke exhaust device, and automatic control system. Using combustible gases such as natural gas, coal water, and liquefied petroleum gas as fuel. Full combustion, high thermal efficiency, and easy control of the combustion process, with less environmental pollution compared to solid and liquid fuels.

    Applications

    Mainly used in processes such as activation, crystal transformation, oxidation, pyrolysis, reduction, emulsification, and sulfation, it is widely used in the drying and calcination of battery materials, such as lithium carbonate, iron phosphate, lithium iron phosphate, cobalt carbonate, ternary precursors, etc.
