Henan Hongke Heavy Machinery Co., Ltd. recently delivered a Φ2.2×45m rotary kiln for catalyst calcination to a chemical plant in Hubei, China. Here's the story.
The Job: Calcining Catalyst Materials
Our customer makes chemical catalysts—used in refineries and environmental systems. These materials need precise heat treatment to develop the right surface area, pore structure, and strength. The customer's old batch furnaces couldn't keep up:
Inconsistent quality – every batch came out a little different
Low output – couldn't meet demand
High energy use – old equipment wasted heat
Poor temperature control – hard to get consistent catalyst activity
They needed a continuous system that could run 24/7 and deliver consistent, high-quality calcined catalyst.
What We Supplied
A complete calcination line built around a Φ2.2×45m rotary kiln.
| Key Spec | Value |
|---|---|
| Diameter | 2.2 m |
| Length | 45 m |
| Operating temp | 300–650°C |
| Temp accuracy | ±5°C |
| Drive | Heavy-duty gear + backup |
The package includes:
Screw feeder – variable speed for consistent feed rate
Φ2.2×45m rotary kiln – continuous calcination, precise temperature control across zones
Atmosphere control – can run inert or reducing gas if needed
Dust collector – cyclone + bag filter keeps it clean
PLC controls – full automation, data logging for quality records
Cooling system – cools product before packaging
Why Catalyst Calcination Needs a Rotary Kiln
Catalyst production is picky. You need:
| Requirement | Why |
|---|---|
| Consistent temperature | No hot spots—uniform product quality |
| Controlled residence time | Get the right surface area and pore structure |
| Gas atmosphere control | Some catalysts need inert or reducing conditions |
| Gentle handling | Avoid breaking formed catalyst particles |
A rotary kiln delivers all of this. Batch furnaces can't match the consistency.
What the Customer Gets
| Benefit | Impact |
|---|---|
| Consistent quality | Stable catalyst activity, batch after batch |
| 24/7 production | No batch changeover losses |
| Higher throughput | Meets growing orders |
| Data logging | Full records for quality certification |
| Lower labor needs | Automated system runs itself |
