Structure features and process  of vertical  kiln

1.Composition :The kiln body is rectangular or cylindrical. There are double-deck burner girders in the kiln body with periphery burners in the middle kiln body. Waste gas drawing-out girder is set on the kiln top. The kiln is divided into five parts: material storage zone, preheated zone, calcining zone, posterior calcining zone, cooling zone.

◊storage zone  is between the kiln gas drawing-out device and the crown. it can store adequate lime stone in order not to stop producing when the crown feed device needs short-term maintenance.

◊ preheating zone is between the kiln gas drawing-out device and the upper burner gireder to preheat lime stone.

◊The part between the upper burner girder and the lower girder the calcining zone where lime stone is calcined into fine lime .Its height can be regulated according to requirement of quality or lime stone physical property.

◊posterior calcining zone is between the lower burner girder and lower gas drawing-out girder  . The lime that was calcined will gain the even and refine quality and raise the activity, when through this zone that has the high temperature and no pressure.

◊ cooling zone joins  lower berner and  lime output , cooling air comes into the kiln from the bottom cools lime stone to 75c and comes out of the kiln.Heated secondary air comes into calcining zone to help burn.
