Drum Cooler
Industrial Cooling Solutions for Post-Carbonization Charcoal Pellets
Drum Cooler Overview
As a core Industrial Cooling Equipment, the Rotary Drum Cooler (also known as Industrial Drum Cooler or Cooling Drum Machine) is a high-efficiency cooling system tailored for high-temperature charcoal pellets from continuous carbonization machines. It enables a seamless “carbonization-cooling” workflow, safeguarding pellet quality and enhancing production safety. By rapidly reducing pellet temperature from 800–1000℃ to ≤50℃, it eliminates spontaneous combustion risks and ensures stable subsequent processing—ideal for biomass carbonization plants, mineral processing facilities, and chemical industries.

Core Components of Drum Cooler
The reliable performance of the Rotary Drum Cooler relies on six specialized components, optimized for continuous industrial cooling demands:
Constructed from Q345R low-alloy high-strength steel (12–20mm thick), the drum’s inner wall features welded spiral guide plates. This design ensures charcoal pellets move uniformly forward without clumping, perfectly matching the feed rate of continuous carbonization machines.
- Air Cooling Unit: A sealed wind hood and variable-frequency centrifugal fan dissipate surface heat from hot pellets, preventing external overheating.
- Water Cooling Unit: An internal spiral water-cooled coil absorbs residual internal heat, forming “internal-external dual cooling.” Together, they achieve rapid temperature reduction and eliminate spontaneous combustion risks.
Equipped with an industrial-grade gear reducer and heavy-duty bearings, it drives the drum at a constant 5–15 rpm. The calibrated gear ratio avoids particle buildup (from rapid rotation) and incomplete cooling (from slow rotation), ensuring uniform cooling for every batch.
- Feeding End: High-temperature resistant sealed hopper (ceramic-lined) minimizes heat loss and air leakage, maintaining cooling efficiency.
- Discharging End: Star-shaped discharger enables steady output, preventing blockages and reducing air backflow—limiting pellet-oxygen contact to avoid spontaneous combustion.
Comes standard with a pulse bag filter that captures 99.5% of cooling dust, ensuring emissions ≤10mg/m³. Complies with China’s GB 13271-2014 and EU’s EN 303-5 standards, preserving pellet purity.
Features high-precision temperature sensors and automatic adjustment of drum speed, fan airflow, and water flow. Temperature fluctuations are limited to ±2℃, with over-temperature alarms (triggered at 60℃) and self-diagnostic functions—ideal for 24/7 continuous production.
Working Principle of Drum Cooler
The Rotary Drum Cooler integrates seamlessly with continuous carbonization machines, following a streamlined four-step workflow:
- Feeding Stage: Hot charcoal pellets (800–1000℃) from carbonization machines are transported to the sealed hopper via a heat-resistant conveyor, ensuring smooth, jam-free entry into the drum.
- Dynamic Cooling Stage: The drum rotates at 5–15 rpm, and spiral guide plates move pellets along the axis. External air cooling removes surface heat, while the internal water coil absorbs deep-seated heat—realizing “synchronous internal-external cooling.”
- Temperature Control Stage: The PLC system monitors discharge temperature in real time. It boosts cooling intensity if pellets exceed 50℃, or reduces it if temperatures are too low—ensuring consistent, safe output.
- Discharging & Dust Removal Stage: Cooled pellets (≤50℃) exit via the star-shaped discharger for packaging or storage. Simultaneously, the pulse bag filter captures dust, and purified air is discharged in compliance with environmental standards.
Core Advantages and Features
Why Choose Our Drum Coolers？
Designed for 24/7 feed and discharge, matching the rhythm of high-volume carbonization lines. Eliminates downtime from batch cooling, boosting overall production efficiency by 8–10x.
Dual-circulation system cools pellets from 800–1000℃ to ≤50℃ in 30–60 minutes. Spiral guide plates ensure uniform contact with cooling media, with batch temperature differences ≤5℃.
Recycled water reduces consumption by 60% vs. single-pass cooling; variable-frequency fans lower energy use by 15–20% compared to traditional coolers.

FAQ About Drum Coolers
Match the cooler capacity to the carbonizer’s hourly output (add 10–20% redundancy for fluctuations) and ensure the drum material (Q345R/304 stainless steel) withstands 800–1000℃ pellets. For example, a 5-ton/hour carbonizer needs a 6–7-ton/hour cooler.

How to Buy the Best Drum Cooler？
Use the formula: Cooling Load (kW) = Material Capacity (kg/h) × Specific Heat (kJ/kg·℃) × Temperature Difference (℃) ÷ 3600. Add 10–20% redundancy for temperature spikes.
Small-scale (≤3t/h): Air cooling (affordable); Large-scale (>3t/h): Dual cooling (24/7 continuous production).
Ordinary pellets: Q345R steel (cost-effective); Weary/impure pellets: 304 stainless steel (longer life). Select industrial-grade motors/reducers to avoid breakdowns.
PLC system for automatic adjustments; IoT remote monitoring for multi-line management (check temperature/energy use via phone).
