The Advanced Manufacturing Process for Horticultural-Grade Vermiculite

The journey from raw vermiculite ore to a high-quality soil amendment involves a meticulous multi-stage manufacturing process, ensuring the final product meets stringent horticultural and agricultural specifications. As a leading vermikuliitti maaperän valmistajassa, our process emphasizes precision and quality control at every step.

Process Flow Overview:

1. Ore Mining & Extraction: High-purity vermiculite ore is extracted from designated deposits. Raw materials are rigorously inspected to ensure minimal impurities, typically with a focus on mineralogical composition (e.g., magnesium-aluminum-iron silicate content) to predict exfoliation characteristics.
2. Crushing & Screening: The raw ore undergoes primary and secondary crushing to reduce particle size. This is followed by multi-deck screening to separate different grades based on particle size (e.g., coarse, medium, fine), which directly impacts its end-use application.
3. Exfoliation (Thermal Expansion): This is the most critical stage. The sized vermiculite flakes are fed into specialized exfoliation furnaces operating at temperatures typically ranging from 800°C to 1100°C. The rapid heating causes the interlayer water in the vermiculite structure to flash into steam, expanding the flakes perpendicular to the basal planes by up to 8-20 times their original volume. This process transforms dense flakes into lightweight, accordion-like granules.
4. Cooling & Secondary Screening: The exfoliated vermiculite is rapidly cooled to stabilize its expanded structure. It then undergoes another screening process to remove any unexfoliated material and to sort the expanded vermiculite into specific particle size ranges (e.g., #1, #2, #3, #4 grades), suitable for various horticultural or industrial applications.
5. Dust Removal & Packaging: A final air classification or dedusting step ensures minimal fine particles, optimizing handling and product purity. The finished product is then packaged into various bulk or bag formats, ready for dispatch by vermikuliitti maaperän toimittajissa.

Quality Assurance and Testing Standards:

Our manufacturing facilities adhere strictly to international quality management systems, including ISO 9001:2015.
