02-09-2013· In the Grate-Kiln System, independent speed control of the grate, kiln and cooler are available to the operator. This provides process flexibility to adjust to changes in concentrate feed.
If you're introducing a new process at your workplace or documenting an existing one, a process map template can help. A process flow chart template uses symbols and diagrams to depict complex processes from start to finish. Just enter your process data to the Excel flowchart template, then export to automatically create the shapes and connectors that visually tell the story.
compared to a traditional rotary kiln flowsheet which is typically applied in vanadium processing. Completion of the pilot scale roasting program enables the BFS engineering design for the concentrate preparation and grate kiln areas to be updated.

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.
11-03-2021· Completion of pilot testing has confirmed that well-established Grate Kiln technology can be used for vanadium extraction at Australian Vanadium's namesake project. Process optimisation by roasting a concentrate representative of average early years mine production has confirmed combined vanadium roast/leach extractions of up to 94.9 per cent.
Figure 3: 3D Model of Grate Kiln Showing Travelling Grate Pellet processing using the Grate Kiln process for vanadium extraction has the following advantages: • Higher reaction progress due to intimate contact with reactants. • Greatly reduced kiln build-up due to melting compounds being contained in the pellet.

The kiln can be preceded by a travelling grate or shaft type pre-heater for preheating the feed in order to improve its fuel economy. When processing lump ore or burnt pellets, it is, in the final analysis, the price of fuel that deter-mines whether a grate or a preheater is used. Compared with the travelling grate…

The Grate, the Kiln and the Cooler. The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed. The Travelling Grate is where pellets are dried and then heated up to a temperature of about 800-900 deg C.
The grate-kiln process, which has been inspired from furnaces designed in the cement industry, uses three distinct pieces of equipment to carry out the induration process: a preheat travelling grate, a rotary kiln, and an annular or straight cooler. Drying and preheating of the green pellets is accomplished on the preheat grate,
