Recently, the Belgian sawdust drying and pelletizing production line project undertaken by Zhengzhou Dingli has been installed and put into operation.

Zhengzhou Dingli biomass drying and granulating production line adopts the principle of die-roll extrusion to process biomass raw materials such as agricultural and forestry residues into solid briquettes to achieve continuous and stable industrial production. The processing route adopts the mixing process of primary drying, secondary crushing, continuous feeding and regulated feeding. The molding rate of pellet molding fuel reaches 98%, and the bulk density and particle density are high.
