Calcining Kilns, Shell-Heated to 1,000 °C and Above
Heat is applied to the outside of the rotating shell, so the material is heated through the wall and combustion gases never touch it.
Electric, Natural Gas or Diesel Heating
Choose the energy source that suits your site. Electric heating gives clean, quiet, easily controlled heat; gas and diesel firing suit plants where fuel is cheaper or grid capacity is limited.
Built for Calcination, Roasting and Carbonization
Calcining kilns can reach 1,000 °C and above, where the material has to reach and hold a high process temperature — not just lose its moisture. The working temperature is set by your material and requirements.
Product Stays Clean
With indirect heating the product is not exposed to flue gas, which protects purity and lets you run a controlled atmosphere for materials that cannot tolerate combustion products.
Continuous, Steady Output
Material feeds in at one end and discharges at the other in an unbroken stream. Rotation speed and inclination set the residence time, so every particle gets the same thermal history.
Hot-Air Kilns for High-Volume Drying and Calcining
Hot air from an external heater passes through the drum in contact with the material — the fastest way to move large tonnages.
Five Heat Sources, One Kiln Design
Hot air can be generated by electric heaters, gas burners, steam coils, diesel burners or coal-fired hot-blast stoves. We size the heater to your kiln and your utilities.
Flights That Lift and Shower Material
Internal flights carry material up and cascade it through the hot gas stream, mixing it continuously so heat and mass transfer stay efficient across the whole bed.
Built for Large Throughput
Long drums running continuously handle mineral, chemical and bulk-material volumes that batch equipment cannot keep up with.
PLC Control With Touchscreen
Temperature, burner and drum speed are managed from a control cabinet with an operator touchscreen, so the kiln runs consistently shift after shift.
Any Fuel, Any Scale, One Supplier
Coal-Fired Hot-Blast Stoves When That Is What You Have
Where coal is the practical fuel, a hot-blast stove feeds the drum with hot air. Gas, diesel, steam and electric options are available when you want cleaner or more convenient heat.
Heavy-Duty Mechanics
The drum turns on riding rings and support rollers with a girth-gear drive — proven kiln mechanics designed for continuous, round-the-clock operation.
Engineered Around Your Material
Shell, internals and lining are specified for your material, temperature and atmosphere. Dust collection and off-gas treatment can be supplied with the kiln.
