According to the basic principles of biomass briquetting of biomass in the molding process of the kind of raw materials, particle size and moisture content has certain requirements. Different ways of pressing the pellet mill feed requirements are also different, extrusion is the core of biomass curing technology, extrusion molding has intermittent and continuous extrusion mode. But the most used type extruder or single screw extruder biomass pellet mill in curing process, which is characterized by the density of briquette, good surface quality and high efficiency. In this way + moisture forming material has a significant impact on the molding, the moisture content is too low, the lignin softening temperature is high, the temperature is too high, the raw material during the extrusion process easy on fire; the softening temperature increases with decrease in moisture content , but the moisture content is too high, the water vaporized after the extrusion process will affect molding, ranging from the rod-like material surface cracks, while generating commonly known as "shooting" phenomenon, disruption of normal shape. In addition, part of the biomass lignin to be heated in order to reach its softening point and cellulose material cemented to each other. Thus, the particles in the extrusion molding machine process must be heated. Curing process of biomass as follows: raw materials → pretreatment (chipping or grinding) → drying → heating → molding, production and sales of new energy workers Yu straw particle machine, wood pellet machine is pressed biomass pellet fuel good choice . 1, composition and working process loop mode particles machine generally consists of feeding chamber, screw feeders, stirring mechanism, forming assembly (roller, ring die pellet mill, cutter, etc.), a gate, gearboxes and Composition motors and other parts of the spiral ring mold roll forming machine type particle feeders, mixing mechanism and forming assembly components: feed screw feeder role played by changing the speed and control of the gate opening to control the amount of feed screw . Stirring mechanism can adjust the angle of the stirring rods, stirring rod arranged in a spiral line, acts as stirring and pushing of powder materials. In the side wall of the mixing chamber is equipped with a nozzle supplying steam or additive, the discharged vapor or mist and powder mix straw particle machine production process, and then into the ring mold chamber molding. The purpose is to increase the feed plus steam temperature and humidity, it is a good shape, improve productivity, and can reduce the wear ring mold. 2. The main components main components ring mold roll type particle molding machine is a ring mold and roll. 1) ring mold ring mold roll forming machine in the form of a ring-type particle structure of die most is monolithic. Drilling shape ring on the ring mold from straw pellet machine, generally circular hole straw pellet machine number of suppliers, the hole diameter of less than or equal to 25 mm, mostly raw materials, wood, molding cavity straight holes for processing particle formation fuel, see chapter 6.3. 2) roll roll roll straw pellet machine assembly ring pattern on the particles forming machine roll straight straw pellet machine volume manufacturing, often with an integral ring mold particles used in conjunction with a larger width dimension of the pressure roller. Roll outer edge shape of the structure and integral ring mold rod (block) -like structure on the same machine press roll, not repeat them here.
