direct reduction process of nickel ores using rotary kiln as the main equipment
Fines generation in kiln process of direct reduction
Direct Reduction Studies : The rotary kiln process of direct reduction was simulated in the laboratory by conducting batch scale tests using Linder test apparatus. The equipment is an electrically heated horizontal reduction tube of size 160mm dia and 630mm length with a facility for rotation of the reduction tube at different speeds.

WORLD DIRECT REDUCTION STATISTICS Midrex
2016 World Direct Reduction Statistics Page 3 SECOND QUARTER 2017 The increase of Indian DRI by almost 800,000 tons can be attributed to a combination of causes. Gasbased DRI plants were aided by lower costs for imported liquefied natural gas and by the stabilization of the coal gasification plants that supply direct reduction furnaces.

Grate kiln systems
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 800900 deg C. The heat used to dry and preheat the pellets is typically hot air pulled from the Kiln and cooler.
