Straw bales shredder The Straw shredder allows you to break up the bale with a minimum of power consumption, lower noise, lower auger speeds and a minimum of wear and tear on the machinery. Consequently it is a highly durable system that can handle stones and other contamination in the straw, without any stops in production and a huge reduction in the risk of creating sparks that can cause a fire. It consists of two contra-rotating augers which are equipped with knifes to break down the bale.
