Switchgrass Grinder Millsfrom United States

Switchgrass (Panicum virgatum L.) is a perennial grass that has been designated as an herbaceous model biofuel crop for the United States of America. To facilitate accelerated breeding programs of switchgrass, we developed both an association panel and linkage populations for genome-wide association study (GWAS) and genomic selection (GS)

    these goals were met. The design target for the switchgrass handling system was 12.5 ton/h (11.3 tonne/h), which we exceeded after a redesign of the secondary grinder in our system. We had hoped to burn over 3,000 tons (2,722 tonnes) of switchgrass during this first round of testing

    Basically, this involved shredding the switchgrass bales in a tub grinder. The result was varying lengths of switchgrass from 0.25” up to 8”. Ultimately this resulted in difficult to feed material that hung up in the system and bunched easily. A better approach involved processing the switchgrass with a hammer mill

Due to the fact that primary mill residues are relatively homogeneous and concentrated at one source, nearly 98 percent of all residues generated in the United States are currently used as fuel or to produce other fiber products.

However, the elevated temperature in future can have differential sensitivity to switchgrass populations as huge genetic variations exist in switchgrass population [8]
