cement mill dampers operation

KELD :: Industries :: Cement

Dampers need to be designed to compensate for the high dust build-ups near the blades as clinker and cement dust can build up rapidly and can obstruct the operation of the damper. KELD uses special materials in this application to ensure long operating life. The typical locations of Expansion Joints and Dampers are:

The operator then notices that the mill temperature is rising and opens one of the dampers on the separator this changes the air flow in the separator. It does begin to cool the mill off but the false air introduced to the separator lowers the differential pressure on the separator and allows more of the course material to return to the mill.

Dust Extraction Systems – Clair

Cement Storage: The cement clinker which is stored is blended with Sulphates, resulting in the formation of gypsum and anhydrite. It is then fed to mills for grinding which results in the production of cement of different qualities. The cement then is sent to silos for storage and then packed in packing plant.

Dampers - Clarage

Routine maintenance can also be performed on the bearings and linkage while the fan is in operation. Clarage designs and manufactures both opposed blade (MLOB) and parallel blade (MLPB) multi-louver dampers. MLOB dampers are commonly used on fan outlets. MLPB dampers, when used on fan inlet boxes, provide increased fan efficiency at reduced loads.
