Frequently Asked Questions (FAQs)
What types of minerals and industrial powders can VibraScreener equipment screen?
Our mineral screening equipment handles industrial minerals like gypsum, feldspar, and mica, base and precious metals such as gold, silver, and copper, plus materials like bauxite and clays. Contact us if your mineral isn’t listed here.
What does check screening mean in mineral processing?
Check screening is a final quality-control pass that runs already-sized mineral product through a screen once more to catch oversize particles or contamination. It’s typically the last step before packaging, standing between a clean shipment and a customer complaint.
How does de-dusting screening equipment work for mineral rocks and powders?
De-dusting equipment vibrates mineral material across a fine mesh screen that separates airborne dust from the coarser product before it escapes into the plant environment. It’s especially common with dry, powdery minerals like gypsum and phosphate.
Why does contamination control matter so much in mineral screening?
In a commodity business, one contaminated shipment can cost a mineral producer their reputation across the broader industry, since buyers talk to each other. Consistent, accurate mesh apertures are what keep contamination out of finished mineral screening batches.
Can VibraScreener equipment handle abrasive minerals like gypsum or corundum without wearing out quickly?
Yes, abrasion-resistant screen options are available, using wire mesh selected to withstand heavy wear from abrasive minerals like gypsum and corundum. Choosing the right resistant screen upfront extends the interval between replacements on high-volume lines.
Should I use a round screener or a rectangular separator for mineral processing?
Round screeners generally suit continuous, high-volume sizing of a single mineral product, while rectangular separators handle more complex separations across multiple size fractions. Your particle size range and required output purity usually determine which mineral processing configuration makes sense.
How do easy-to-clean screener designs benefit mineral processing plants?
Screeners built for quick opening and cleaning cut the time between product changeovers, which matters when a plant runs multiple minerals through the same line. Faster cleaning means less downtime for mineral processing plants and more time in production.
Does VibraScreener also handle wet mineral slurries, or only dry screening?
This equipment is built primarily for dry powders and granular minerals, but we manufacture separate equipment for wet mineral slurries under our liquids and slurries line.
