Henan Hongke Heavy Machinery Co., Ltd. just completed installation and commissioning of a rotary kiln for magnesium oxide (MgO) calcination in Liaoning, China. The system is now running. Here's the story.
What the Customer Needed
This customer makes refractory materials. They wanted to expand their MgO production. Their old equipment couldn't keep up—quality was inconsistent, and output was too low.
They needed:
Consistent MgO quality – stable reactivity, every batch
24/7 operation to meet demand
Precise temperature control – MgO is sensitive to heat
Dust control that meets environmental rules
Brand-new equipment – no used machines
Why They Chose Us
They looked at several suppliers. Here's why they picked us:
We know MgO calcination – it's not the same as lime or cement
We built it for their magnesite – sized for their feed, their moisture, their target
We supplied the whole line – kiln, burner, dust collection, controls, everything
We stay after commissioning – spare parts, technical help, maintenance advice
What We Supplied
A complete MgO calcination line built around a rotary kiln.
| Key Spec | Value |
|---|---|
| Application | Magnesium oxide calcination |
| Kiln type | Rotary kiln with refractory lining |
| Temp | Up to 1,200°C (zoned control) |
| Drive | Heavy-duty gear with backup |
The system includes:
Controlled feed system
Rotary kiln with high-alumina refractory
Multi-fuel burner (gas or coal)
Dust collector (cyclone + bag filter)
Discharge and cooling system
PLC controls with temperature monitoring
