Bamboo Powder Pellet Press

Brief Introduction

The Bamboo Powder Pellet Press is a vertical ring die biomass pellet mill, specifically designed for pelleting hard bamboo materials such as bamboo powder and bamboo shavings. It relies on pressure rollers to compress the material, utilizing the bamboo's own lignin to bind and form the pellets without the need for additional adhesives. This machine can compress bamboo processing scraps into high-density bamboo pellets. Addressing the high hardness of bamboo fibers and the tendency for the die to wear easily, this machine uses a high-compression-ratio alloy steel ring die, making it suitable for continuous industrial bamboo production. It is the core pelletizing machine for the resource utilization of bamboo waste and can be integrated into a complete bamboo pellet production line for automated pelleting.

Processing Technology

Core Equipment Is Bamboo Powder Pellet Press

Bamboo scraps are crushed → hammer milled to a fineness of 2-5mm → drum drying with moisture content adjusted to 10-15% → conveying and feeding → high-pressure extrusion granulation in a bamboo powder pellet mill → fixed-length cutting by a cutter → cooling and hardening in a counter-current cooler → sieving and powder removal → automatic packaging of finished products. The material is subjected to strong extrusion and friction within the pelleting chamber, causing the lignin to soften and be forcibly pressed into the ring die holes for forming. After cooling, the pellet hardness increases, reducing breakage and powder loss.

Suitable Raw Materials

Bamboo powder, bamboo shavings, bamboo wood chips, bamboo branches, bamboo strips, bamboo scraps, and bamboo product processing by-products; also compatible with various biomass raw materials such as sawdust, straw, palm shells, and giant grass, supporting mixed pelleting of bamboo and sawdust to reduce mold wear. Raw materials need to be pre-crushed to remove mud and impurities and control the appropriate moisture content.

Application Areas

1. Energy Supply: The processing system produces pellets as an alternative fuel to coal and oil for industrial boilers and kilns. Typical applications include steam boilers for textile and food plants, as well as heating kilns used in ceramics and building material sectors. Consistent pellet output guarantees reliable energy delivery.

2. Power Generation: Biomass power stations consume massive volumes of standardized pellet fuel. Large-scale processing machinery satisfies power plants’ strict specifications on pellet calorific value and density, maintaining high combustion efficiency and steady power output.

3. Agriculture & Livestock: Certain models manufacture straw pellets for animal bedding or raw pellets for organic fertilizer production. Flexible process adjustments allow the equipment to cater to diverse agricultural applications.

Details

1.Gear‑box Unit: Custom‑developed by Zhejiang HUIXIN for TONY, marked with both brand logos. Internal gears are enlarged and thickened and gear‑shaft structurally reinforced to satisfy heavy‑load working conditions.

2.Corrosion‑Resistant Component Material: Feed inlet, discharge housing, dust collecting cover, lifting knife and built‑in cutting knife are constructed of grade 304 stainless steel, counteracting rust and corrosion caused by process steam and improving overall equipment service durability.

3.Reducer Configuration: HUIXIN hard tooth‑surface reducer is mounted under discharge housing. The structural arrangement offers high output torque and sufficient rotation power and decreases component failure occurrences.

4.Upper Discharge Housing: Fabricated from 304 stainless‑steel with arc geometry. High tensile strength prevents welding‑stress cracking risk; curved exterior reduces potential operator injury risks.

5.Rotary‑Support Improvement: Rotary‑support assembly is relocated beneath discharge housing. Compared with conventional top‑mount design, it prevents steam corrosion exposure and addresses rust and wear defects of internal steel balls.

6.Material Lifting Knife: Thickened stainless‑steel construction grants good resistance against high‑temperature steam. It guarantees effective material stirring circulation and prevents raw‑material accumulation inside pelletizing chamber.

7.Inner Cutting Knife Function: The internal cutting knife supports stroke adjustment. By changing cutter extension length, operators control finished pellet dimension with easy‑to‑operate tuning steps.

Unique Advantages

1. The comparison parts are the material-contacting chamber, feed housing, and discharge housing; the main frame base is made of carbon steel.

2. For the same 110 kW power output, Tony uses 304 stainless steel for the material-contacting parts, while some competitors use lower-cost 201 stainless steel. Although their hardware power parameters are the same, the material properties differ significantly.

3. Particularly suitable for processing biomass raw materials containing organic acids, such as bamboo powder, giant grass, and straw; suitable for humid southern plant areas; and for producing high-quality export pellets and feed pellets.

4.It has better toughness than 201 stainless steel, and is less prone to brittleness when subjected to abrasion from material particles, resulting in a lower failure rate of the casing and reduced replacement costs for later parts.
