Product description

Introduction

The Three-cylinder Dryer for Ore is purpose-built for mining and beneficiation: ore concentrate, tailings and mineral raw materials. It turns wet concentrate into dry, stable product ready for smelting, briquetting or transport.

The thickened shell and wear-resistant lining stand up to high-hardness ore, while the dedusting system recovers fine dust as product — all with triple-pass heat exchange cutting fuel by 30-40% versus a single-drum dryer. With 8-75 t/h models from 2.0×4m to 3.6×8m, mining operations of every scale get reliable ore drying.

Hot Questions Ore Buyers Ask Most

1. Ore is hard and abrasive — can the dryer handle the wear?

Yes. The thickened shell, wear-resistant lifting plates and replaceable inner lining are built for high-hardness ore, and proven in 24/7 mining duty with low maintenance.

2. What ore sizes and moisture levels can it process?

Granular ore and concentrate up to 30 mm with 10-20% moisture are standard; the uniform material curtain exposes every particle to the hot air stream for even drying.

3. Is dust control available for concentrate drying?

Yes. A cyclone plus bag filter captures fine dust and returns it to the product — keeping emission clean and recovering fines that would otherwise be lost.

Ore Application Scenarios & Complete Line

Concentrate Drying: Copper, iron and zinc concentrate dried before smelting — lower transport cost and higher smelter value.

Tailings Handling: Dried tailings for safe storage, backfill or reuse as construction material.

Mineral Raw Materials: Bauxite, manganese ore and quartz pre-dried for refining and processing.

Briquetting Feed: Dry fine ore prepared for briquetting and pelletizing lines.

Complete ore drying line: concentrate thickener → filter press → vibrating feeder → three-cylinder dryer → multi-cyclone & bag filter → product silo — engineered for continuous, single-operator-per-shift production.

Working Process for Ore Drying

1. Feeding: Filtered concentrate or crushed ore is fed evenly into the three-layer nested cylinders via belt or vibrating feeder at a stable, adjustable rate.

2. Turning & Dispersing: Wear-resistant lifting plates lift and turn the ore into a uniform material curtain — every particle dried evenly, plate wear minimized.

3. Heat Exchange: Hot air at 700-750°C passes through the ore three times inside the short shell, maximizing moisture pickup per unit of fuel.

4. Moisture Evaporation: Ore travels from the inner cylinder to the outer one; final moisture drops to the level your process needs — 3-8% for concentrate, lower for special products.

5. Discharge & Dedusting: Dry ore discharges to the product silo; fine dust is captured by the multi-cyclone and bag filter and returned to the product — clean emission, zero fines lost.

FAQ

1. How is the dryer protected against ore wear?

A thickened cylinder shell, wear-resistant lifting plates and a replaceable inner lining are standard, giving long service life in high-hardness ore duty.

2. What ore sizes and moisture can it process?

Granular ore and concentrate up to 30 mm with 10-20% moisture are standard; the uniform material curtain dries every particle evenly.

3. How is dust controlled during concentrate drying?

A multi-cyclone plus bag filter captures fine dust and returns it to the product — clean stack emission and zero loss of valuable fines.

4. What final moisture can be achieved?

Typically 3-8% for concentrate and tailings, adjustable down to lower levels for special products, via temperature, rotation speed and feed rate.

5. What capacity range is available?

Eight models from 2.0×4m to 3.6×8m cover 8-75 t/h, serving small beneficiation plants up to large mining groups.
