The variable speed infeed system on the 6400XT Wood Hog horizontal grinder consists of a top feed wheel with internal drive, and a 60-inch wide live floor equipped with four individual strands of WDH-120 chain in a staggered configuration. The MICS system will automatically adjust the feed speed of the bed chain and feed wheel in real time during operation, based on engine load and a variety of other parameters. This will provide more effective settings to the grinder, allowing better engine efficiency, increased production, and a more consistent end product.
