Drying Ovens

High-performance hot air drying ovens engineered for reliable, uniform drying of mineral and laboratory samples in industrial and research environments.

LAARMANN industrial hot air drying ovens (HAD) are mostly used for easy drying of wet mineral samples for chemical analysis. The spacious and easy to operate the HAD-range will certainly impress you. The ovens are well proven and suit a range of application and sample loads, cores to granular and filter cake (coming from the pressure filter). They are cost effective and can be used ahead of crushing and pulverising, saving you valuable time. LAARMANN offers 3 sizes, 2,5m3, 5,0m3 and 10,0m3. We can recommend the best option for you based on your operational requirements.

Drying Ovens FAQ (Frequently Asked Questions)

A drying oven is an industrial hot-air chamber used to remove moisture from mineral and laboratory samples to prepare them for chemical analysis or processing. They ensure uniform drying without contamination and are essential in lab and industrial sample prep.

Choose based on sample volume and throughput needs. Small units (e.g., 2.5 m³) are ideal for labs, while larger units (5.0 m³ or 10 m³) handle higher production loads efficiently.

Temperature accuracy, chamber capacity, safety controls, energy efficiency, and ease of operation are key features that affect performance and usability.

Yes, LAARMANN drying ovens are suitable for granular material, filter cake, cores, and many wet mineral samples, providing consistent drying across various materials.
