Mining rotory dryers are equipment specially designed for the mining and metallurgical industries, mainly used to process mineral raw materials or industrial by-products containing water. Its main uses and applicable scenarios are as follows:

Drying of mineral raw materials

1. Metallic ores (such as iron, copper, lead, zinc, etc.): In mineral processing, the ore often needs to be crushed, floated, or magnetically separated. Drying can reduce moisture and improve the efficiency of subsequent processing.

2. Non-metallic ores (such as quartz sand, kaolin, bentonite): Remove moisture to meet industrial standards (such as raw material moisture content requirements in ceramic and glass production).

3. Coal: Drying can reduce transportation costs, improve combustion efficiency, or be used to prepare water-coal slurry.

Handling of industrial by-products

1. Slag and tailings: After drying, they can be used as cement admixtures and building materials (such as brick making) to achieve resource recycling.

2. Sludge or waste residue: Metal-containing waste generated in metallurgical or chemical processes, which is easy to extract valuable components or safely stack after drying.

Auxiliary mineral processing technology

1. Drying before flotation: Some ores need to control the moisture content to optimize reagent adsorption and flotation effect.

2. Dehydration of concentrate: Drying can be used as a supplementary step after filtration or centrifugal dehydration to ensure that the concentrate meets the sales or smelting requirements (such as copper concentrate water content must be less than 10%).
