travelling grate in iron ore pelletising

Traveling grate - After feeding the pellets to the traveling grate, the unit operations of green ball drying, concentrate dehydration, partial calcination, and partial induration are performed on a traveling grate, whereupon heat transfer occurs in zones of the grate from the cross flow of process gas (hot air) repeatedly passed through the pellet.travelling grate in iron ore pelletising,Iron Ore Pellets Induration Solutions - Metal 7So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process. Once fired, they can be handled, loaded in ships or trains and delivered to the end users. Two indurating furnace technologies dominate the pelletizing industry, the straight travelling grate and the.

Study of the induration phenomena in single pellet to traveling grate .

The process for pelletizing iron ore fines is an important operation unit for producing high quality of raw materials for the subsequent reduction processes such as blast furnace or direct reduction. The process essentially involves production of green pellets and induration on a traveling grate furnace to promote inner partial.

Drying and preheating processes of iron ore pellets in a traveling grate

Abstract: A mathematical model of drying and preheating processes in a traveling grate was presented based on the laws of mass, momen- tum, heat transfer, and drying semiempirical relations. A field test was systematically carried out in a traveling grate. The effects of pellet diameter, moisture, grate velocity, and inlet gas.

A schematic diagram of the grate-kiln induration process is shown in Fig.1. The mixture of ground iron ore, additives, binder and coke breeze are rolled into balls by pelletizer. These green balls are deposited on the traveling grate to form a bed of 180mm-220mm depth by the feed conveyer. First, the moist pellets are dried.
