What it does
Coal slime is a pain to handle. It comes out of the washing plant wet, sticky, and clumps together the moment it sits still. This rotary dryer is built specifically for that problem.
Inside the drum, special anti-sticking lifting plates keep the material moving and breaking apart as it tumbles. Hot air moves through the drum, pulls the moisture out, and what's left is dry, loose coal slime that's actually usable. Power plants burn it. Briquette makers press it. Fuel processors blend it. What used to be a disposal headache becomes a product with real market value.

What makes it work
It doesn't gum up. The internal structure is designed around the stickiness problem. Those anti-bonding plates keep the slime from gluing itself to the drum walls-the exact issue that kills most coal slime drying setups.
It handles volume. This isn't a small-batch machine. It runs steady and continuous, which is what you need when a washing plant is dumping waste by the truckload.
Heat source is your call. Coal burner, gas burner, diesel, or a hot air furnace-whatever fuel makes sense for your site and your budget, the dryer matches it.
Safety isn't an afterthought. Coal slime burns. That's the point. So the system comes with dust removal and fire protection built in. Combustible material needs handling carefully, and this setup does that.
Where you'll see it
Coal washeries getting rid of waste. Briquette plants making fuel. Thermal power stations prepping material. Mineral processing operations recovering what used to be thrown away.
How we handle the project
You tell us your hourly capacity, how wet the slime is coming in, and what fuel you want to use. We'll build the scheme around that. Layout drawings and installation guidance come with it.
Every unit runs a factory test before it's packed and shipped. ISO and CE paperwork available. After it arrives, remote video guidance gets your crew up to speed, and spare parts stay available long-term.
Common questions
Q: Coal slime sticks to everything. Will it clog the drum?
That's the exact problem this machine solves. The lifting plates are designed to stop bonding from the start. If your slime is wetter than usual, we'll adjust the internal structure to match your working conditions.
Q: What heat source should I use?
Most coal slime operations run a coal-fired hot air furnace. Fuel is cheap, running costs stay low. If coal isn't practical for your site, gas or oil burners work just as well.
