APPARATUS FOR SLAG MELT GRANULATION AND GRANULATION METHOD TO PRODUCE A DRY PRODUCT Russian patent published in 2020 - IPC C04B5/02 

FIELD: mining.

SUBSTANCE: group of inventions relates to a slag melt granulation apparatus, a slag melt granulation method to produce a dry product. Slag melt granulation unit comprises a molten metal chute, a metal drum configured to load metal balls therein and can be rotated about a horizontal axis together with balls which do not fall out during its rotation. Installation also contains a hollow drum with a meshed body, which is filled with metal balls by 20–30 %. Melt chute is located on the drum end face. Under the chute nose there is a liquid slag dispenser made in the form of a water jet with nozzles directed upward at angle of 30–45 degrees and towards the drum rotation direction at angle of 15–30 degrees relative to the drum axis. Proposed method comprises granulation of liquid slag in metal drum with metal balls rotating around its horizontal axis. Liquid slag is fed into grate drum from its end along melt chute, dispersing slag flow falling from tip of said chute, by water jets in ratio from 0.35 to 0.5 t/t of slag.

EFFECT: technical result is improved operation reliability.
