What it's for
Mine slag, water-quenched slag, mineral processing residue-whatever you call it, it comes out wet and heavy. Before it can be used as cement additive, building aggregate, or road base, the moisture has to come down.
That's where this rotary dryer comes in. Wet slag feeds into a spinning drum, gets lifted and dropped through hot air, and the water leaves. What's left is dry, usable material that was once a disposal problem.
For mineral processing plants and solid waste recycling projects, this machine sits at the center of the operation. It's the thing that turns waste into something someone will pay for.

Why it holds up
Slag grinds at everything it touches
The drum is heavy-duty, and the inside is lined with wear-resistant material. Abrasive particles bounce around in there all day. The liner takes the beating so the shell doesn't have to.
The material actually spreads out
Multiple groups of lifting plates keep the slag tumbling and scattering through the hot air instead of sliding along in a pile. Better dispersion means better heat use, which means you're not burning fuel for nothing.
It runs and runs
Big capacity, continuous operation. This isn't a machine you start and stop every few hours. It's built to run through shift after shift without complaint.
It plays well with others
Crushing and screening equipment connect directly. If you're building a full slag processing line-crush it, dry it, screen it, ship it-this dryer fits right in the middle without awkward modifications.
Where it's used
Mineral processing plants recycling waste. Cement plants prepping raw material. Building material operations making aggregate. Mine sites dealing with solid waste.
How we work with you
Give us three things: particle size, feed moisture, and how many tons you need to dry per hour. We'll match the drum to those numbers and send layout drawings and installation guidance.
Every machine completes a factory test run before packing. ISO and CE documents available. Spare parts stay stocked, and technical support continues after the dryer's running on your site.
Common questions
Q: What moisture range can it handle on the inlet side?
Most mine slag runs 12–30% moisture coming in. The outlet moisture depends on what you're doing with the material after it's dry. We set that to match your downstream process.
Q: Can it work with a crusher?
That's the standard setup for a lot of operations. We can provide a complete flow chart for a full crushing and drying line, so the whole system is designed to work together from the start.
