FAQS on vermiculite

Q: What is coarse vermiculite primarily used for?

A: Coarse vermiculite is mainly used as a soil amendment in horticulture for improved aeration and moisture retention. It also serves as an insulation material in construction and a protective packaging filler. Industrial applications include fireproofing additives and lightweight concrete aggregates.

Q: How do I select reliable coarse vermiculite suppliers?

A: Verify supplier credentials like ISO certification, mineral purity test reports, and industry experience. Prioritize those offering consistent quality control and sample evaluations. Ensure they provide clear shipping logistics and responsive technical support.

Q: What capacity should a coarse vermiculite factory have?

A: Reputable factories typically handle large-scale production, often exceeding 10,000 tons annually with multi-grade processing lines. Facilities should feature exfoliation furnaces for particle expansion and automated screening for size consistency. High-volume output ensures timely bulk order fulfillment.

Q: Can coarse vermiculite manufacturers customize particle sizes?

A: Yes, leading manufacturers offer customized sizing, typically from 1mm to 8mm granules. They adjust crushers and sorting meshes to meet specific horticultural or industrial requirements. Custom bulk packaging options are also commonly available.

Q: Why choose coarse over fine vermiculite for construction?

A: Coarse grades provide superior insulation and fire resistance due to lower density and higher expansion ratios. Their thicker granules enhance structural integrity in plasters or lightweight concretes. This reduces material weight while maintaining thermal stability in high-temperature applications.
