Installation for the manufacture of cement by dry process with precalcination furnace.

摘要

An installation for the dry manufacture of cement comprises a preheater heat-exchange unit of series-connected cyclones, a precalcination kiln and another cyclone associated therewith, a clinkerization kiln and a clinker cooling chamber associated with this kiln. To distribute the hot air coming from the cooling chamber suitably between the precalcination and clinkerization kilns, a device is provided for creating a gas pressure loss in the circuit between the last cyclone of the preheater and a point where a smoke gas outlet conduit of the cyclone associated with the precalcination kiln is connected to the circuit downstream of the last cyclone.
