Iron Concentrate

1. Material Overview

Iron concentrate is a mineral powder produced from iron ore through crushing, grinding, and beneficiation. It is the main raw material for pelletizing, and its iron content directly affects the quality of the pellets. Ultra-pure iron concentrate with TFe≥71.5% and hydrochloric acid insoluble matter ≤ 0.3% is used in the powder metallurgy industry.

2. Process Introduction

Wet iron concentrate from the upstream section is fed into the steam rotary dryer. Inside the dryer, as the cylinder rotates, the wet iron concentrate is lifted and dispersed by the heating tubes, and it is dried by multiple heat exchange methods, including convection, conduction, and radiation. The material moves from the higher end to the lower end due to the dryer's inclination, and is finally discharged through a rotary discharge valve at the tail end of the steam rotary dryer. Adjusting weir plate at the discharge end of the dryer is installed to regulate the material filling rate within the cylinder. Combined with the cylinder's inclination and rotation speed, this allows for adjustments to the material's residence time, filling rate, and output requirements.
