High-Temperature Shaft Kiln - FLSmidth
Our High-Temperature Shaft Kiln sets the benchmark in the refractory industry. By utilising the preheated air as secondary air, which has previously been used for cooling the product at the discharge end of the kiln, we ensure that very little heat is lost in the process – and achieve superior thermal efficiency. Furthermore, thanks to the vertical kiln’s high flexibility, it can
