Flowability Aids for Coal and Iron Ore: What Every Bulk Material Handler Must Know
Wet coal and sticky iron ore are among the most persistent operational headaches in mineral handling. When bulk material clings to chute walls, clogs bunkers, or jams conveyors during the rainy season, production throughput suffers immediately. The solution is not more manpower or unplanned shutdowns. It is chemistry applied at the right point.
At Sudha Speciality Chemicals Private Limited, our SUFLOW range of flowability aids is engineered specifically for Raw Material Handling Plants (RMHP) dealing with coal and iron ore.
What Are Flowability Aids?
Flowability aids are specialty chemical additives applied to bulk materials to prevent clumping, moisture absorption, and surface adhesion. When coal or iron ore becomes wet, surface tension causes particles to bind together, making them stick to equipment and resist gravity-fed movement.
A high-performance flowability aid works by absorbing or repelling moisture at the particle surface, restoring free-flow characteristics without altering the material’s core properties.
Two Main Categories of Flowability Aids
Flowability aids are broadly grouped into two types based on their mechanism of action:
Category | Mechanism | Best Used For |
|---|---|---|
Moisture Absorbers (Hygroscopic Agents) | Chemically absorb free moisture from the bulk material surface | Wet coal in monsoon season, high-humidity storage yards |
Surface Conditioners (Anti-Caking Agents) | Coat particle surfaces to prevent inter-particle adhesion and sticking to equipment | Iron ore in transit, chute and bunker discharge, conveyor belt movement |
Both types can be used independently or in combination depending on the severity of material wetness and the specific handling equipment involved.
SUFLOW: Sudha Industries' Engineered Solution
The SUFLOW range covers both categories and is formulated for Indian mining and power plant conditions.
SUFLOW Parameter | Coal | Iron Ore |
|---|---|---|
Dosing Rate | 150 to 200 GPT | 70 to 110 GPT |
Moisture Absorption Ratio | 1 gm absorbs approx. 100 to 120 gm of moisture | 1 gm absorbs approx. 100 to 120 gm of moisture |
Application Point | Conveyor belt, bunker inlet | Conveyor belt, screening section |
Primary Problem Solved | Chute jamming, belt clogging | Chute blocking, screening inefficiency |
This absorption ratio is what sets SUFLOW apart. Very few commercially available flowability aids achieve this level of performance per gram of chemical applied.
Where SUFLOW Delivers Results
Coal Handling Plants: During monsoon, coal fed from stockyards to boilers through conveyor belts becomes wet and blocks chutes. SUFLOW instantly conditions the surface, restoring discharge flow.
Iron Ore Processing (DRI and Sinter Plants): Wet iron ore creates screening jams and delays feed to DRI and sinter units. Post-SUFLOW treatment, ore passes through screens freely with measurably higher throughput per hour (TPH).
Bunkers and Silos: Stagnant wet material creates bridging inside bunkers. SUFLOW prevents inter-particle bonding that causes bridging.
