Product introduction of straw coal forming machine

Straw coal briquetting machine is also called straw coal forming machine. This machine refers to a machine that uses rural crops such as corn straw, wheat straw, cotton straw, rice straw, rice husk, peanut shell, corn cob, branches, leaves, sawdust and other solid wastes (such as edible fungus residue and furfural residue) as raw materials, and then produces "straw coal" after crushing, pressurizing and concentrating. Production and processing procedures of straw fuel molding machine: cut materials over 60mm with straw cutter or crush them with pulverizer, and the particle length and water content of the materials are within the specified range; The material is evenly delivered to the material port above the molding machine by a feeder (belt conveyor) or manually, and the finished product is obtained by press molding. From the source of raw materials to the use of fuel, the process is as follows: material recovery → chopping → automatic metal removal from feeding → pressing → molding → output → cooling → transportation → biomass power plant or small boiler or civil use.

The principle of solid briquetting XH series straw briquetting machine uses the principle of the interaction between the extrusion force between the flat die and the press wheel and the friction force of the die hole to shape the material. In the process of processing, there is no need to add any additives or adhesives to the material. Straw and other materials contain a certain amount of cellulose and lignin, which is a structural monomer in the material and a phenylpropane polymer compound. It has the functions of strengthening cell wall and binding cellulose. Lignin is amorphous, its main part is insoluble in any solvent at room temperature, and it has no melting point but only softening point. When the temperature reaches a certain value, the softening and cohesive force of lignin increases. Under a certain pressure, its cellulose molecular groups are dislocated, deformed and elongated, in which adjacent biomass particles mesh with each other and recombine to form briquettes.

The application scope of straw coal forming machine "straw coal";

Straw coal can replace firewood, raw coal and liquefied gas, and is widely used in household stoves, heating stoves, hot water boilers, industrial boilers and biomass power plants.
