Vertical pre-heater is one of the main equipments of the lime production line,
Its main function is to heat the material eventy to 900"C in the pre-heater by the
Waste hot gas (about 1150 "C ) discharged from the kiln, after the material which
Was earned to the top of the kiln fed tothe pre-heater, during the preheat, about
30% CaCOa break down, which was later transferred to the kiln for calcination by
the Hydra ulic Lever. this flowchart not only short the calcination time, but also
You can get more higher activity grade of lime.
     Vertical pre-heater mainly consist of the following parts:
     1, Upper feeding system; 2, Pre-heater main body; 3, Pusher
4, Hydraulic system: 5, Lower feeding chamber; 6, Frame
