High-Capacity Chain Conveyor for Fertilizer & Mining

Description

Our systems utilize high-strength, heat-treated alloy chains to drive precision-engineered scrapers through a fully enclosed trough. This ensures that even the most hygroscopic (moisture-absorbing) fertilizer granules, such as NPK or Urea, are transported without spillage, dust emission, or exposure to external humidity.

Applications & Use

Our drag chain conveyors are customized for the following heavy-duty industrial scenarios:

Fertilizer Industry: Specifically designed for NPK, Ammonium Phosphate, and Urea handling. Our corrosion-resistant chains combat chemical aggression.
Mining & Metallurgy: High-capacity transport of coal, iron ore, ash, and minerals in abrasive environments.
Biomass & Energy: Efficiently moving wood pellets, biomass fuel, and coal powder with dust-tight configurations.
Animal Feed & Agriculture: Gentle handling of grains and feed pellets to reduce product breakage during long-distance conveying.

Key Benefits



Extreme Corrosion Resistance

SYM chains are specifically heat-treated and surface-coated to withstand the acidic and alkaline nature of chemical fertilizers, ensuring a long service life in aggressive environments.



Zero-Spillage & Dust Containment

Featuring a fully enclosed design with bolted removable covers, our conveyors prevent material loss and protect your facility from hazardous dust and moisture.



Smart Safety Features

Equipped with zero-motion sensors, overflow sensors, and emergency stop switches, SYM conveyors detect blockages at the outlet before they lead to equipment failure.



Adjustable Tensioning System

Our precision-engineered tensioning section allows for easy chain adjustments, preventing "chain jumping" and ensuring smooth operation even under maximum load.

FAQ

How do you reduce residue in the conveyor?

We use durable UHMW-PE scrapers that provide a clean-sweep action against the trough, minimizing material cross-contamination and residue.

Can SYM chain conveyors handle long-distance transport?

Yes. Our high-capacity designs are engineered for stable, long-distance horizontal conveying, often used as the backbone of fertilizer production lines.

What happens if there is a blockage at the outlet?

Our integrated anti-block sensors and overflow sensors will trigger an automatic emergency stop, preventing damage to the chain and motor.
