Engineers at a pennsylvania company have found a spinning solution to the dilemma of removing fine sand from sand-laden manure better than current technology can accomplish. They are currently field-testing a hydro-cyclone device that has been able to remove 98 percent to 99 percent of sand from manure (as part of a manure handling system) before it reaches storage lagoons or methane digesters. The prototype has been placed immediately following the test dairy’s Sand Manure Separator. As the former bedding material is fed into the cyclone, centrifugal force pulls sand grains finer than 200-mesh, or 0.0029-inches, out of suspension. The separated fines are then recombined with the sand produced by the Sand Manure Separator, and all the separated sand is reused for bedding.
