Indirectly Heated Rotary Kiln Sealing Around Fully Enclosed Guards

This is why, at Hengyang, we have designed and engineered an Indirect Rotary Kiln that aims to provide a solution to these problems. Rather than applying heat directly to the material – as direct rotary kilns do – the Indirect Rotary Kiln is heated from the outside, where the material is heated via contact with the outer kiln shell. This allows for a more tightly controlled environment, which is especially effective when used primarily in the lithium from spodumene industry. The kiln is also suitable for use with any minerals bearing ore from which the action of mineral acids extracts metals.

For this reason, we have manufactured our indirect rotary kilns to be highly robust, ensuring minimal maintenance and a longer service life. With our kiln, you also benefit from reduced fuel consumption and waste gas emissions, which is both cost-effective and sustainable.

For these reasons, our indirectly heated rotary kiln is the best of its kind, making this product your ideal choice when you need high-quality material processing at your facility.

Hengyang’s Indirect Rotary Kiln offers numerous benefits designed to optimise your facility while reducing operating costs and maintenance.

Our Indirect Rotary Kiln comes with many safety features, including:

• Sealing around the outer shell to prevent dust and gaseous emissions escaping into the atmosphere
• Insulated enclosing of the exposed rotary kiln shell and the heater box assembly to prevent burns or heat-related injuries
• Fully enclosed guards around all pinch-points to prevent injury
• Built-in gas analysers for the safe combustion of fuels
• Separate handling and treating of exhaust gases to reduce gas and dust emissions

Versatile kiln options

Hengyang offers you both gaseous fuel combustion and electrically heated kilns, allowing you to decide which type of kiln best suits your needs.

Durable shell

The kiln’s robust rotating shell allows for both an extended service life and the flexibility to process a large variety of materials.
