Flow controlling intermediate diaphragm with adjustable scoops.
Its ability to maintain the material level in the diaphragm ensures it to regulate material load in the 1st compartment
Commerical Name : Opticontrol®.
Industries : Cement
Place of use : Ball mills
Technical specifications:
Flexible structure to absorb the dynamic deformation and forces of mill shell
The design & material hardness of the grates are the key points to keep slots as original for a long time
Central screen design is according to volume load
Reduced pressure drop because of cylinder use instead of cone design
Key Benefits:
Optimization of cement grinding
Lesser wear than conventional diaphragm 
Possibility of material retention independent of slot sizes and ball charge density
The material level in the 1st compartment is controlled by the level of the material level inside the diaphragm.
