Sintering Machine for Large-Scale Iron Ore Agglomeration

Description

When you choose the SYM belt-type sintering machine, you select a robust unit designed for continuous, reliable operation under significant thermal and mechanical stress. It delivers stable sinter quality and predictable output for long-term productivity. We provide various sizes and grate area options to match your specific production goals, plant layout, and investment plans.

Key Benefits

As the central equipment in a large-scale sintering line, the SYM belt-type Sintering Machine creates sustained value for our customers in the following key areas:

How It Works

SYM’s sintering machine is based on the proven straight-grate (belt-type) sintering principle, widely adopted in large iron and steel plants worldwide.

In this configuration, sinter pallet cars travel continuously along a straight strand, passing through charging, ignition, sintering, and discharge zones. Downdraft suction through windboxes drives the sintering process, ensuring controlled heat transfer and uniform sinter formation across the bed.

This straight-grate design supports long strand lengths, large grate areas, and stable thermal profiles—key requirements for modern high-capacity sinter plants.

During operation, the main drive system of the sintering machine drives the head star wheel, pulling the pallet cars into continuous circulation.

• On the upper strand, pallets receive a hearth layer and mixed raw materials via a precision charging system
• The material bed is ignited under the ignition hood
• Continuous downdraft airflow through the windboxes supports progressive sintering along the strand
• At the discharge end, finished sinter is tipped and discharged
• Empty pallet cars return along the lower strand to the charging zone, completing the operating cycle

This continuous operating mode enables stable output, consistent sinter quality, and predictable process control.

Key Features

Our disc granulator is proven across copper smelting, lead smelting, and iron ore pelletizing projects, delivering measurable improvements in production performance.

Solving Critical Sinter Plant Operating Challenges

SYM engineers its sintering machines to directly address the main factors affecting energy consumption, reliability, and maintenance cost.

Air Leakage Control for Energy Efficiency

Air leakage between pallet cars and windboxes reduces effective airflow and increases fan power consumption. SYM addresses this through:

• High-integrity double-leaf spring pallet seals
• Reinforced sealing at windbox inlets and main flue interfaces
• Optimized tail-end sealing design

Ensuring Pallet Car Train Stability

To prevent pallet lifting (“arching”) and misalignment—common causes of wear and unplanned downtime—the sintering machine incorporates:

• Precision-engineered star wheel tooth profiles and tail curve geometry
• Freely moving tail carriage with accurately calculated counterweight systems
• Durable pallet wheels, axles, and slide plates designed for long service life
• Clear guidance on synchronized replacement of rails, seals, and wear components
