We’re excited to share that we’ve just shipped a wood sawdust log maker machine to a customer in Angola! As one of Africa’s major agricultural players, Angola boasts a thriving sunflower plantation industry that produces tons of agricultural waste, like sunflower seed shells, each year. Our customer is investing in this machine to turn that waste biomass into valuable fuel.
Raw material characteristics and core requirements
The main raw material for the customer is sunflower seed husk, known for its impressive calorific value (16-18 MJ/kg), low density, and fluffy fiber structure. However, traditional processing methods come with a few hurdles:
- High storage costs and fire risks associated with loose materials.
- Low efficiency in direct combustion (only 35%-40%) leads to significant environmental pollution.
- A shortage of automated equipment to facilitate large-scale production.
The customer has clear needs, which include:
- Compressing sunflower hulls into standardized fuel rods with a density of at least 1.0g/cm³.
- Ensuring that a single machine can handle continuous operation of over 200kg/h.
- Adapting to the power fluctuations and the high temperature and humidity conditions found in Africa.
Technical suitability of SL-50 wood sawdust log maker
To meet the needs of Angolan customers, SL-50 biomass sawdust briquette making machine provides the following solutions:
| Molding method | High-pressure molding with four-side molds (peak pressure up to 120MPa) |
| Production capacity | 250kg/h (suitable for raw materials with moisture content of 8%-15%) |
| Power system | 18.5kW three-phase motor (compatible with 380-420V wide voltage) |
| Temperature control system | Dual redundancy temperature control by electric heaters + heating rings (±2℃ accuracy) |
| Structural design | Compact body (occupies an area of only 1.04 square meters) |
Customized upgrade and service guarantee
- This wood sawdust log maker machine comes with a pre-crushing module that breaks down sunflower seed shells into 3-5mm particles.
- It features reinforced motor insulation and a moisture-proof coating, making it suitable for environments with up to 85% humidity.
- The molded fuel produced has a calorific value of 4300kcal/kg, which can serve as a substitute for charcoal, helping to alleviate the pressure on our forests.
- Plus, it includes a free spiral pusher, heating ring, and other essential spare parts to help keep maintenance and operational costs low.
This project not only showcases how adaptable this wood sawdust log maker machine is to challenging climates and various raw materials, but it also sets a technical standard for the large-scale use of agricultural waste like cashew nut shells and bagasse in Angola.
