How In-Line Sand Blending Plants Work
Screened -4 mesh (<5mm) sand fractions are pumped to a Hydrocyclone mounted above a Hydrosizer™. The Hydrocyclone serves to concentrate the feed to the Hydrosizer™ for more efficient operation and also to remove amounts of -200 mesh (<75µm). They Hydrosizer™ splits the feed into two streams: nominally coarse and fine. Generally, the cut is between 30-50 mesh (600-300µm).
After the coarse and fine material is separated as underflow and overflow respectively, the coarse fraction is directed to the product stream while the fine fractions are directed to a blending vessel via a Hydrocyclone. A programmable logic controller-based algorithm then controls the ratios by which the fractions are blended on the fly.
Final products are dewatered using Dewatering Screens for a drip-free discharge. Any sand resulting from controlling the main product is directed to a separate dewatering process.

Frequently Asked Questions
My deposit is variable. Is this a problem for this plant?
An In-Line Blending Sand Plant can handle some variation if it is understood up front and designed into the plant. In cases of large variation, a Recipe Sand Plant may be a better fit because of the bin capacity built into the plan
