Preheating Tower JR-5-12 Suspension Preheater for Cement Kiln Production Line

The Preheating Tower JR-5-12 preheats cement raw meal using the hot exhaust gases leaving the rotary kiln, recovering heat that would otherwise be wasted and preparing the feed for rapid calcination. Raw meal is suspended and contacted with rising hot gas in a series of cyclones, where it is dried and heated before entering the kiln. Because the feed arrives already hot, the kiln can be shorter and can reach a higher output for the same fuel input. Refractory-steel pushers and wear-resistant components stand up to the hot, abrasive material, and the modular structure is built for reliable continuous operation in cement plants.

• Efficient Heat Recovery: Hot kiln exhaust gas preheats and dries the raw meal, recovering heat and cutting overall fuel consumption.
• Higher Kiln Output: Preheated feed enters the kiln ready for calcination, raising clinker output for the same kiln size and fuel input.
• Multi-Stage Cyclone Design: A series of cyclones brings the raw meal into close contact with the hot gas for effective, staged preheating.
• Refractory Steel Pushers: Pushers made from refractory steel resist high temperature and abrasion, extending the life of the moving parts.
• Modular Robust Structure: The tower is built from sturdy, modular sections that assemble quickly and stand up to non-stop cement plant duty.
• Reliable Continuous Operation: Simple, well-supported mechanical components keep the preheater running dependably with low maintenance.

Suspension preheaters are used in cement plants ahead of rotary kilns to dry and preheat raw meal, and in lime and metallurgical plants to prepare feed materials. They are a key part of modern energy-efficient cement production lines, improving output and reducing specific fuel consumption.

The preheater ships as modular sections with the refractory-steel pushers and frame protected, and the drive units crated separately. A complete set of drawings and an operating manual are provided, and components are inspected before dispatch. We provide a twelve-month warranty and a reliable supply of pushers and wear parts to keep your preheating system efficient.
