Dependable lime production starts with controlled calcination. SINOTECE supports kiln selection, fuel adaptation, product activity control and cleaner operation for stable lime plant performance.
PFR Twin-Shaft Lime Kiln
The PFR twin-shaft lime kiln is centered on alternating regenerative heat exchange and stable combustion. It is suitable for lime projects with high requirements for product quality, energy consumption, operating stability, and environmental compliance. We provide integrated delivery from process design and packaged equipment to installation, commissioning, ramp-up, and stable operation support for both new and retrofit projects.
