Product Description

Vertical Preheater   
There is a bin on the top of preheater and a level indicator that controls the height of materials layer; materials slipping pipe, set between the bin and preheater, can transfer limestone into preheater and meanwhile seal the materials to prevent the entrance of cold air. Raw materials, using waste gas of high temperature, moves in opposite direction of materials feeding to achieve full heat exchange. The materials, after being evenly preheated, are pushed into the kiln by hydraulic push rod to reduce the time that materials are calcined in the kiln. Flue gas is discharged into atmosphere after being treated by dust collector.
