Co-production of WPC Fillers and Incense Powder: Technical Selection Guide for Multi-functional Grinders

Co-production of WPC Fillers and Incense Powder: Technical Selection Guide for Multi-functional Grinders

In Indonesia’s biomass processing sector, enterprises are increasingly diversifying their operations. Many incense manufacturers are leveraging their raw material advantages to enter the Wood-Plastic Composite (WPC) supply chain. However, WPC fillers and incense wood flour differ significantly in particle size distribution and physical properties. To achieve compatibility on a single production line, equipment must possess exceptional fineness flexibility and thermal stability.

Comparative Performance Requirements
While the raw materials may be the same bamboo scraps or sawdust, downstream processes demand different wood flour specifications:
Incense Industry: Focuses on superfine powder (typically 80-200 mesh), requiring complete fiber pulverization to ensure a smooth surface and stable combustion.
WPC Fillers: Focuses on consistency in mesh size (typically 60-100 mesh). Overly fine powder (above 300 mesh) increases melt viscosity during plastic processing, while overly coarse particles compromise the strength of the composite.

Technical Logic for Multi-functional Production
High-performance wood powder machines utilize an integrated design to switch production modes on a single platform, meeting diverse industry standards.
1. 10-500 Mesh Stepless Adjustment System
By adjusting the speed of the Analyzer at the top of the unit, operators can rapidly switch between coarse powder (WPC grade) and superfine powder (Incense grade). Combined with a triple-stage crushing system—Type 7, Type 1, and Centrifugal knives—the machine ensures the production of high-quality acicular or spherical particles at various mesh sizes, enhancing the nail-holding power of WPC materials.
2. Consistency Assurance via Double-layer Water Cooling
Regardless of the product, heat buildup is the enemy of consistency. WPC fillers require low moisture content and zero thermal degradation. The double-layer body with circulating water cooling ensures that even under high loads of 15kW-90kW, the grinding chamber remains below 50°C. This prevents lignin charring and ensures chemical stability when the wood flour bonds with plastic resins.

Selection Guide: Evaluation Metrics for Multi-functional Lines
For B2B buyers in Indonesia, building a line that serves both WPC and incense markets should focus on these parameterized indicators:
Capacity-to-Power Ratio: For the high-volume demands of WPC, models like the WPM-800 or WPM-1000 are recommended to ensure an hourly output of 1-3 tons.
Feeding System Safety: Self-priming feeding is mandatory. As WPC raw materials may contain outdoor-collected waste, this system effectively filters out sand and stones to protect precision blade sets.
Environmental Integration: The risk of dust explosion increases when producing superfine powder. A Pulse Dust Collector must be configured to achieve Dust-free production, complying with Indonesian environmental regulations.
