Acrowood

Acrowood and its predecessors Black Clawson and Sumner Iron Works have supplied chippers and forest products equipment for more than 100 years. The common thread for all this machinery has been efficient and reliable operation with minimal maintenance. Since the 1970s, Acrowood's robust design disc scalpers have provided years of trouble free operation, reliably segregating grossly over-sized material and contaminants from wood chips, sawdust, bark, and other biomass or fuel stocks. Acrowood Slant Disc Chippers have long been used to efficiently reduce wastewood from sawmills, producing high quality pulp chips from sawmill residues. Dual drive suspended rotary screens sort over-length material and fines from wood chips and are also used to screen sawdust and biomass prior to further processing. The unique screen design locates drive components outside the screen pan for easy maintenance access. Acrowood also manufactures and supplies disc thickness screens and its unique DiamondRoll thickness and fines screens which offer superior screening efficiency for chip thickness screening systems. Air density separation systems process a variety of feedstocks, removing high density contaminants such as biological knots, metal, or rocks.
