Over the past few decades in rural areas, after the harvest of crops, a large amount of crop straw was a problem due to lack of storage space. Households without livestock would burn the straw to address the land issue. Burning was both unsafe and polluted the air. Now, with the continuous popularization of mechanization replacing manual labor, small agricultural machinery is scattered throughout households, and the advent of shredders has brought relief to the disposal of crop straw. Livestock farmers also have an abundant supply of forage and feed, and power plants have access to raw materials for electricity generation. As a result, the urgent need for large-scale, high-yield straw shredders has emerged.

The small corn straw shredder can process crop straw and feed into powder form, mainly used for shredding straws, wheat straw, cotton stems, peanut shells, corn cobs, tree branches, and medicine powder. Working principle of the small corn shredder: The shredded material enters the shredding chamber from the feed hopper, where the cutting knife first cuts the material, followed by the hammer blades for further shredding, all in one go. The fineness is controlled by the screen mesh, and the wind pressure generated by the shredder directly expels the shredded material.

The large automatic grass powder machine can process a variety of dry materials such as corn stalks, wheat straw, rice straw, sorghum stalks, chrysanthemum stalks, soybean stalks, wheat straw, peanut vine stalks, sweet potato vine stalks, peanut hulls, dry weeds, corn, sorghum, dried sweet potatoes, broken soybean cakes, and other杂粮. It can grind these materials into powder with lengths ranging from 3mm to 10cm.
