Why McLanahan In-Line Sand Blending Plants
The key to utilizing an In-Line Sand Blending Plant is to understand the process up front and maintain a balance within the system. McLanahan and our highly experienced personnel have history and knowledge in doing both. Our in-house lab and proprietary simulations ensure a plant can be designed to meet specific needs and capacity requirements. With the full line of McLanahan equipment, industry experts and our world-class Field Service Team, a solution to your application is just a few steps away.
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.
Popular Applications for In-Line Sand Blending Plants
In-Line Sand Blending Plants can be used to create various types of sand, including foundry sand, plaster sand, glass sand, concrete sand, filter sand and sports sand.

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
