GRATE COOLER Page 1 of 1
Or, the design can be upgraded to one with airbeams or mechanical air flow regulators for small groups of grates. Some suppliers, borrowing from the airbeam technology, offer a grate plate design for pre1990's coolers where the air has to travel through a labyrinth in the grate – first up, then down – before exiting into the clinker bed.

Pelletizing LKAB
In the process, large amounts of energy are generated when the magnetite oxidised to form haematite, which reduces the energy requirement by 60 percent. As LKAB has two different types of pelletising plant – straight grate and gratekiln plants – the drying process varies slightly.

Pelletizing an overview | ScienceDirect Topics
Jan 01, 2012· In GrateKiln process, green pellets are fed on oil or gasfired endless Straight Grate machine where they are dried and preheated. The preheated pellets are then fed to a rotary kiln where their temperature is raised in oxidizing atmosphere to 1290–1400 °C. In induration, ore grains are sintered together with oxidation and slagforming bonds.

Moreover, the kiln skin will appear liquid phase in advance, which reduces its viscosity and deteriorates the kiln's ventilation, and eventually forms an even heavier reduction atmosphere. In the production process, we can tell if there is a reduction atmosphere by observing the clinker color and the gas composition parameters in the kiln.
