The JDX series straw briquetting machine adopts the principle of the interaction between the extrusion force between the flat mold block and the pressing wheel, as well as the friction force of the mold hole, to achieve the formation of materials. The material does not require any additives or binders to be added during the processing. Straw and other materials contain a certain amount of cellulose and lignin, which are structural monomers in the material and are high molecular compounds of phenylpropane type. It has the function of enhancing cell walls and binding cellulose.

Straw machine refers to a machine that uses agricultural crops such as corn straw, wheat straw, cotton stalks, straw, rice husks, peanut shells, corn cobs, tree branches, leaves, sawdust, and solid waste (such as edible mushroom residue, wine residue, furfural residue, etc.) from rural areas as raw materials, which are crushed, pressurized, and densified to produce "straw coal".
