I. INTRODUCTION.

Grate-kiln-verkets konstruktion med en förvärmande bandugn (grate) och en roterugn (kiln) har sitt ursprung i cementindustrin där tekniken 

The traveling grate is used primarily to dry and preheat green balls for feeding into the rotary kiln, where they are indurated. Once the green balls are made they are spread out evenly across the grate.

In shaft furnaces the charge moves down by gravity and is heated by a counterflow of hot combustion gases, but the grate-kiln system combines a horizontal traveling grate… Table of ContentsProcess Design ImprovementsMechanical Design ImprovementsCoal Firing The economics of pellet plant operation, in terms of fuel and power consumption, flexibility in the selection of the cheapest fuel source, system availability, maintenance costs, and the simplicity of process design, contribute to the determination of building and profitably operating a pellet plant. Design Plant overview Grate-KilnTM iron ore pelletizing system The first Grate-KilnTM system pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed.

The traveling grate is used primarily to dry and preheat green balls for feeding into the rotary kiln, where they are indurated. Once the green balls are made they are spread out evenly across the grate. The first form of grate cooler used on British kilns was the Bucket Grate. The cooler was built into a greatly-enlarged kiln hood, with length about 1.9 times the kiln diameter, and width 15% greater than the length. A concave grate-plate occupied the entire base, with a pressurisation chamber below. 515 East Platt Avenue Nashwauk, MN 55769 (218) 885-0061 Office Slag formation in the grate-kiln process is a major problem for iron-ore pellet producers. It is therefore important to understand the slag formation mechanism in the grate-kiln production plant.
