What is a screw briquette machine？
Product Description
Core Definition: Continuous Biomass Densification Equipment
A screw press briquetting machine is a specialized piece of equipment that uses a screw shaft to compress and generate heat through friction, converting loose biomass raw materials into high-density briquette fuel. Belonging to the category of biomass briquetting machines, it differs from hydraulic wood briquette making machines and flat-mode briquetting machines, primarily targeting continuous, large-scale production scenarios. Its core function is to densify the raw materials through physical processes, without the addition of chemical binders. The finished product density can reach 1.0-1.3 g/cm³, and the calorific value is stable at 4200-4800 kcal/kg, making it the mainstream model for industrial-grade biomass fuel processing.
Core Structure: Four Systems Working Together
The sawdust charcoal extruder machine consists of four core parts: a feeding system, a screw extrusion system, a forming system, and a transmission system. Compared to ordinary briquetting machines, it has a more complex structure and a higher degree of automation. The feeding system includes a hopper and a mixing device to prevent raw material accumulation and bridging. The screw extrusion system uses an alloy steel screw shaft, whose wear resistance far exceeds that of ordinary briquetting machine parts. The forming system is equipped with replaceable die holes to adapt to different specifications of finished products. The transmission system consists of a motor and a reducer to ensure stable power output; the motor power of small models is 15-37kW, and large models exceed 55kW.
Differentiated Characteristics: Advantages of Screw-Type Briquetting Machines
Compared to hydraulic and flat-mode briquetting machines, the core advantage of the screw-type briquetting machine lies in its continuous operation capability-hydraulic machines are intermittent, limiting hourly output; flat-mode machines are suitable for small-scale scenarios, while screw-type machines can achieve an hourly output of 1-5 tons, suitable for large-scale processing. Simultaneously, relying on frictional heating, it requires no additional heating device, resulting in 20%-30% lower energy consumption than hydraulic briquetting machines, and producing high uniformity of finished products with a breakage rate of less than 5%, resulting in superior overall performance.
Industry Positioning: Mainstream Choice for Mid-to-High-End Briquetting Machines
Small screw briquette machine is widely used in biomass fuel plants and large-scale wood processing plants due to their mature technology and high stability, making them a core category in the mid-to-high-end briquette machine market. While their price is higher than flat die wood chip briquette machines (mid-sized models costing 80,000-150,000 RMB), their long-term operating costs are lower and their production capacity is higher, making them the preferred equipment for those seeking economies of scale and aligning with industry development trends.
