China HZP Series Direct Heating Rotary Drum Dryer - Leading Suppliers & Factory for Efficient Drying Solutions

The baking kiln, also referred to as a calcination kiln, is an essential device for the high-temperature thermal treatment of powdered or filter cake materials. It is available from leading China suppliers and manufacturers specializing in advanced industrial equipment. These kilns come in two main types based on energy sources: electric heating and natural gas heating. They are further categorized by their heating methods into direct heating and indirect heating options. Additionally, baking kilns can operate in continuous or intermittent modes, These versatile kilns are primarily employed in a variety of processes, including activation, crystal transformation, oxidation, pyrolysis, reduction, halogenation, and sulfation. Their widespread use spans several industries such as petrochemicals, inorganic chemicals, metallurgy, and construction, making them a crucial asset for the production of specialized materials. As a prominent factory in the industry, we ensure that our baking kilns meet the highest standards of efficiency and reliability

    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.

    Frequently Asked Questions

    What is the difference between electric and gas-fired roasting kilns?
    Electric roasting kilns use electricity as energy, reaching operating temperatures of 400 ℃ to 1000 ℃, and feature a simpler, more compact setup. Gas-fired roasting kilns utilize combustible gases like natural gas or LPG, reaching operating temperatures of 400 ℃ to 900 ℃, and offer high thermal efficiency with lower environmental impact compared to solid or liquid fuels.
    Which battery materials can be processed in these roasting kilns?
    They are widely used for the drying and calcination of battery materials, including lithium carbonate, iron phosphate, lithium iron phosphate, cobalt carbonate, and ternary precursors.
    How is the roasting time controlled during operation?
    The roasting time of materials can be adjusted and controlled by changing the rotation speed of the furnace drum or by adjusting the angle between the furnace drum and the horizontal plane.
    What processes are these roasting kilns suitable for?
    These kilns are mainly used for processes such as activation, crystal transformation, oxidation, pyrolysis, reduction, emulsification, and sulfation.
    What safety and insulation features do the kilns have?
    Both types feature advanced automatic temperature control and segmented settings. Electric models keep the surface temperature rise of the insulated furnace below 50 ℃ to minimize heat loss, while gas models are equipped with accidental power outage protection systems and reliable combustion controls.
