Xrido Group RDF Pre-Shutter: The Core Engine of RDF Plant Raw Material Processing
RDF (Recycled Distillery Fuel) plants use mixed municipal solid waste and industrial solid waste as raw materials to produce high-calorific-value fuel through crushing, sorting, and drying processes. The "uniform crushing" of the raw materials is crucial to the quality and production efficiency of RDF. As the core equipment for front-end raw material processing in RDF plants, the RDF pre-shredder can crush large, mixed raw materials into uniform particles, laying the foundation for subsequent processes. Leveraging its deep understanding of RDF production characteristics, Xrido Group has launched a professional RDF pre-shredder, becoming a key support for the efficient operation of RDF plants.
The core advantage of the Xrido Group RDF pre-shredder lies in its strong adaptability to complex RDF raw materials. RDF raw materials have diverse compositions (including plastics, paper, wood, kitchen waste, etc.) and often contain large impurities (such as furniture and packaging barrels). Traditional pre-shredders are prone to problems such as "entanglement and jamming." This equipment employs a dual-shaft, low-speed, high-torque structure, coupled with an anti-winding blade design and wear-resistant alloy cutter heads (hardness up to HRC62). Through a dual force of "shearing + extrusion," it can crush large raw materials into uniform particles of 30-50mm. Even highly entangled plastic films and fibrous materials can be efficiently crushed, preventing equipment downtime. Data shows that RDF plants equipped with this equipment experience a 45% increase in front-end raw material processing efficiency and a 65% reduction in downtime due to material jams.
In the RDF plant's production process, the Xrido Group RDF pre-shredder further optimizes subsequent processes. The crushed raw materials have uniform particle size. During the sorting stage, air and magnetic separation equipment can more accurately separate metals and inert impurities (such as bricks), improving the purity of the RDF raw materials. During the drying stage, the uniform particles have a larger specific surface area, increasing heat transfer efficiency by 30% and shortening drying time by 25%, effectively reducing energy consumption. Meanwhile, the crushed raw materials are easier to mix with other auxiliary materials, allowing for precise control of the calorific value of RDF (typically stable at 16-22 MJ/kg), meeting the needs of different combustion scenarios and enhancing the market competitiveness of RDF products.
Furthermore, the Xrido Group RDF pre-shredder balances environmental protection and durability. The equipment employs a fully enclosed crushing chamber and a negative pressure dust removal system, controlling dust and odor generated during the crushing process within national standards, meeting the environmental requirements of RDF plants. The machine body is welded with 12mm thick wear-resistant steel plates, and core components undergo anti-corrosion treatment, resisting the erosion of corrosive substances in the raw materials (such as kitchen waste leachate), extending its service life to over 20 months. The built-in intelligent overload protection system can automatically shut down when encountering uncrushable hard objects, protecting the equipment and reducing maintenance costs.
Against the backdrop of the "dual carbon" goal driving the utilization of waste-to-energy, the Xrido Group RDF pre-shredder, with its characteristics of "high-efficiency crushing, quality assurance, environmental friendliness, and durability," has become a core piece of equipment for upgrading RDF plants. Choosing Xrido Group can solve raw material processing challenges, improve RDF production efficiency and product quality, and help RDF plants achieve high-quality development in the waste-to-energy sector.
