Detailed introduction of each section of the production line

Crushing Stage:

 The integrated crusher is the front-end equipment of the production line, primarily crushing various types of trees, small-diameter timber, logging residues (such as branches and twigs), and wood processing residues (such as bark, strips, log cores, veneer, etc.). It can also crush materials such as demolition waste, construction formwork, and urban recycling waste, as well as wood-iron mixtures containing nails, metal, and thin sheet metal. Furthermore, it can crush non-wood materials (such as hemp stalks, reeds, bamboo, corn stalks, and cotton stalks). Based on our company’s experience in manufacturing drum chippers, this machine was meticulously designed according to the characteristics of raw materials and the particle size requirements of biomass power plants. It features wide raw material adaptability, high output, reasonable structure, simple operation, safety and reliability, and convenient maintenance, making it an ideal integrated biomass crusher both domestically and internationally.

Fine Grinding Stage:

The teardrop-shaped pulverizer is a meticulously developed and standardized product of our company, primarily used for pulverizing various wood chips, wood strips, straw, weeds, etc. This series of teardrop-shaped pulverizers adopts direct-drive shaft transmission and a high-speed motor. The pulverizing chamber utilizes secondary impact technology, resulting in finer and more uniform particle size. Furthermore, the machine can rotate clockwise and counterclockwise, ensuring even wear of the pulverizing rotor and hammers, maintaining effective pulverization balance throughout use. This avoids structural issues reported by customers, such as high output and stable operation initially, followed by significant vibration and output decline after a few months. The main shaft bearing uses imported NSK high-quality bearings, and the main unit features a sliding door and elastic pressure screen structure, simplifying operation and maintenance. This machine boasts high output and low power consumption, capable of general pulverization as well as fine and micro-fine pulverization. It is widely used in large and medium-sized biomass pellet plants, feed mills, citric acid plants, food factories, and other industries.

Drying Stage:

The stacked high-efficiency rotary drum dryer differs from traditional airflow dryers, single-drum dryers, three-pass dryers, three-cylinder dryers, and vacuum dryers. It overcomes many shortcomings of other models, such as the low output of airflow dryers, the low thermal efficiency of single-cylinder dryers, the ignition susceptibility of three-pass dryers, the slow discharge speed and low air pressure of three-cylinder dryers, and the high cost and large footprint of vacuum dryers. Its thermal efficiency ratio is currently industry-leading both domestically and internationally, based on real customer feedback, reaching up to 1:12.5. Furthermore, it can be designed with various combustion methods according to user needs, including biomass burners, log combustion chambers, wood chip combustion chambers, and natural gas. The working principle of the rotary drum dryer is to dry sawdust through hot air and mechanical motion. First, hot air is generated in the combustion chamber and sent into the drum. The material undergoes mechanical motion inside and outside the drum, allowing for full contact and conduction of hot air and moisture, thereby evaporating the moisture in the sawdust and achieving the drying effect.

Pellet production stage:

The vertical ring die biomass pellet mill is a meticulously developed product series by our company. It incorporates the best features of pellet mills both domestically and internationally. Its core component is a “two-layer mold, integrated through-shaft, two fixed and two vertical transmission” assembly structure, ensuring stability and scientific design. The pressure roller is made of high-alloy wear-resistant material, resulting in a lifespan several times longer than similar products. The transmission structure features automatic grease filtration for thorough lubrication. It boasts a unique design, reasonable structure, low energy consumption, high efficiency, and robust wear resistance.
Applicable raw materials include, but are not limited to: wood (pine, poplar, fir, branches, bark, sawdust, shavings, etc.), straw (corn stalks, wheat stalks, rice straw, rice husks, peanut shells, cotton stalks, etc.), and waste materials (construction templates, furniture scraps, wooden pallets, municipal waste, medicinal residue, mushroom residue, sludge, etc.).
