Straw briquette machine is an equipment that extrudes agricultural wastes such as straw, corn stalk, rice stalk, peanut shell into high-efficiency, high-density and environment-friendly fuel or feed.

According to different structural principles, straw briquette machine can be divided into different categories.

Ring molding briquette machine:

Ring molding briquette machine can be divided into single roller (roller) ring molding briquette machine and multi-roller ring molding briquette machine (usually double rollers, sometimes more than two). The molds of ring molding machine are generally I-shaped modules arranged in a circle, and the mold holes are mostly square, which can also be customized according to customer requirements; The ring mold also has an integral module, and the hole pattern is mainly round. This briquetting machine has a high rotating speed and a large output, but its pressure is very small, so it is only suitable for pressing concentrated feed, because the concentrated feed has a large raw material ratio, good fluidity, sugar content, easy molding and a little pressure.

Moulding briquette machine:

It has simple structure, convenient maintenance,  it is very suitable for small-scale manufacturers and individual users.

Stamping briquette machine:

It has high pressure, high molding rate and low power per unit. However, due to the limitation of stamping structure principle, the maximum output is often low. The punch and die are easily damaged due to frequent impact force, so it is not easy to replace, and the output is small, so it is not suitable for large-scale production lines.

Vertical ring mould pressing block briquette machine:

Vertical feeding, directly in place, stationary mould, rotating pressing wheel, centrifugal material, evenly distributed around, two layers of mould, dual-purpose upper and lower, ring mould, vertical structure, which is beneficial to heat dissipation in granulation room. The briquetting machine with this structure has the advantages of high pressure, extremely high molding rate, which can reach 95%, and large output, and is suitable for large-scale production lines. Vertical ring molding block machine has high automation degree and strong material adaptability.
