RDF Pellet Mills Are Machines For Making Refuse Derived Fuel Pellets From MSW, SRF, And RDF Waste. The Pellet Size in 20mm-30mm, 3000-5000 Kilo Calorie High Heat Value. This Is New Waste Treatent Of Solid Waste.
RDF pellet mills of punching type and ring mode type are the most commonly used Types. Their pellet size, output, and raw material processed range is different. Which machine is more suitable can be determined according to the project needs.
RDF ( refuse derived fuel ) pellet mill is also called RDF briquetting machine. The crushed MSW waste is transported into the RDF pellet machine, and after many high-frequency punching, you could get RDF pellets without any adhesive. This machine is a stamping-type pellet mill. The motor configuration is between 45kw and 75kw, the output can reach up to 3 tons/hour, and the energy consumption is less than 50% compared with other types of MSW pellet machines.
RDF pellets or SRF Pellets refer to the cylindrical pellets made by the RDF pellet machine. After crushing and screening the municipal solid waste (or industrial waste), the RDF material is pressed into 20-30 mm pellets. To ensure the service life of the mold and reduce the cost of crushing and pressing, unless there are special requirements, the pellet diameter is not suggested too small (8-10mm).
At present, the most commonly used raw materials for making RDF pellets usually include MSW waste, SFR, industrial solid waste, waste from the paper mill, waste woven fabrics, waste soft plastics, leather, rags, etc. RDF pellets can be used as alternative fuels, suitable for power plants, cement factories, large boilers, gasification power generation projects, etc. But that’s not all boilers workable for the pellets.
We all know that the cost of making RDF pellets is not low, and this is not a small investment project also. There is an unavoidable key point, since the waste can be burned directly, why pressing into pellets or briquettes?
This is because the calorific value of raw MSW is only about 1000 kcal, and the average moisture content can be up to more than 40%, the combustion effect is not satisfied. In addition, the transportation cost is very high, which limits the MSW treatment. After making RDF pellets ( crushing, sorting, drying, pressing ), the calorific value increased by 3-4 times (depending on the raw materials and ingredients). The moisture content is very stable within 20%, and the combustion calorific value is stable, which can be used in many high-energy-consuming projects and factories.
Different from traditional biomass pellet production, the pre-treatment process of RDF pellet will be more complex, which is caused by the raw material composition. The moisture content is high and uneven, and the material is light and soft. If the processing flow design is unreasonable, it is easy to consume too much energy, and the RDF pellet mill out lower than expected.
In the plant, there are one or two shredding processes, at least one sorting process, the drying process determined according to the waste composition, and last is pellet making.
The combustible RDF is generally light and soft (paper, textiles, plastic ). Therefore, in the material conveying and feeding process, a special design to prevent winding&clogging is a must, a uniform device to ensure capacity is also required. From many years of experience, we have successfully solved these technical difficulties and can provide turnkey project services.
There are many types of RDF pellet mills on the market now, however, the RDF pellet mill should be market-oriented. What we need to do is not only to help you solve pellet making but also to support you develop your fuel market beforehand.
Different markets have different requirements for pellets( size, moisture content, and calorific value ), so all the production lines are designed and customized according to your end market needs. Our most popular product line is the output demand of 5-6 tons per hour, and our largest production line designed has achieved 40 tons per hour, and the output and operation are very stable.
Double head and split-type molds design produce different diameter pellets by one machine
It has a wide range of moisture adaptability, and the material can be pressed without drying, energy-saving
Siemens automatic control system, equipped with a material uniform tool, solves clog
Equipped with a water cooling system and dust removal system, 24 hours continuous production
The stamping type MSW pellet machine is very convenient to maintain, only needs to replace the worn parts regularly, fully automatic forced lubrication, no need to add grease like other machines. Notes are as follows.
For the large size of MSW waste or industrial waste, it is necessary to use a shredder and screening of incombustible materials. The remaining RDF can be mixed evenly for pellet making.
We have provided many machines for many large-scale RDF pellet and briquette production projects. The following is the working video for your reference.
The processing process of municipal solid waste and industrial waste is different from the traditional production of biomass pellets. Especially in the heating process, we must ensure that the entire system sealing well, and minimize dust leakage. We could design a central dust removal system, spark detection, and automatic fire extinguishing system in the workshop as an optional option.
Industrial waste does not need to be dried, but MSW and landfilled waste need doing that sometimes. Such projects generally require the support and subsidies of government policies.
In the planning stage of the project, you may face many problems. We are glad to communicate with you in detail on the following issues.
The area required for this pellet line workshop depends on the daily production capacity and material storage situation. But it generally requires three areas, raw material storage, processing workshop, and finished product storage workshop. Raw material & finished product area can be adjusted according to your workshop.
Power plants have requirements for pellet’s calorific value and moisture content. Which depends on your material composition. The requirements for large industrial boilers are higher. You can contact us for more details.
Depending on the project scale, the delivery time usually ranges from 30 days to 120 days. We will deliver the plant in a short time as soon as possible while ensuring product quality and service.
We manufacture pellet production lines and briquetting production lines for biomass, MSW, and industrial waste. We are a professional factory with more than twenty years experience in machinery production, so we believe that we are the best choice for each other.
