In non-metallic mineral processing and industrial raw material production, moisture control directly affects product quality, transportation costs, and downstream processing efficiency. Whether dealing with kaolin, bentonite, gypsum, silica sand, barite, or clay, excess moisture leads to agglomeration, increased grinding energy consumption, reduced product value, and even compromised end-use performance.
The Mineral Dryer is a professional drying system specifically developed for industrial minerals and non-metallic mineral processing. Utilizing rotary drying technology combined with gentle drying processes and anti-burn design, it efficiently removes moisture while preserving mineral crystal structure, maintaining whiteness, and retaining activity. Whether you are processing sticky clay, fine powder minerals, or granular ores, one Mineral Dryer can handle the job, helping you enhance product value and reduce operating costs.
The Mineral Dryer is widely used for drying various industrial minerals and non-metallic minerals:
| Mineral Type | Typical Materials | Value of Drying |
|---|---|---|
| Clay Minerals | Kaolin, bentonite, ball clay, fire clay | Control moisture to improve plasticity, whiteness, and market value |
| Carbonate Minerals | Limestone, dolomite, calcite | Reduce moisture for grinding and downstream processing |
| Sulfate Minerals | Gypsum, anhydrite, barite | Dewater to meet building material and chemical industry standards |
| Silicate Minerals | Silica sand, feldspar, diatomite | Remove moisture to improve purity and flowability |
| Other Industrial Minerals | Talc, graphite, mica, vermiculite | Precise moisture control to preserve layered structure and physical properties |
This industrial mineral dryer utilizes a co-current rotary drying process, optimized for mineral characteristics.
Feeding & Breaking: Wet minerals are fed into the cylinder via a conveyor. For sticky minerals (such as clay and kaolin), a powerful breaking device at the feed end forcibly disperses agglomerated material to ensure uniform drying.
Gentle Heat Exchange: A hot air furnace generates hot air (temperature precisely adjustable between 120°C-600°C based on mineral thermal sensitivity), which fully contacts the minerals inside the cylinder. The cylinder interior features a combined lifting plate system, constantly lifting the material to form a uniform “material curtain” that maximizes heat exchange efficiency.
Anti-Burn & Quality Protection: For high-whiteness minerals (such as kaolin and gypsum) and heat-sensitive minerals, we employ low-temperature drying modules and precision temperature control systems to prevent discoloration, decomposition, or loss of activity due to overheating.
Gas-Solid Separation: The dried minerals are discharged via a discharger, while dust-laden exhaust gas enters a high-efficiency pulse baghouse filter to ensure environmental compliance. Recovered fine powder can be directly returned to the final product, achieving zero loss.
