ASR to SRF: From Waste to Resource
Automotive Shredder Residue (ASR) is an inevitable by-product of vehicle dismantling and metal recycling. It typically consists of plastics, rubber, fibers, foams, coating fragments, and small amounts of metal, with a complex composition and large density differences. If disposed of directly in landfills, it not only occupies land but may also cause environmental pollution. Converting ASR into Solid Recovered Fuel (SRF) provides an effective way to utilize these materials as a resource, creating economic value for enterprises.Challenges in ASR ProcessingAlthough ASR is combustible, its processing faces three major technical challenges:Complex composition and difficult separationASR contains various plastics, rubber, and fibers that are tightly interwoven, making separation inefficient and limiting fuel purity.Irregular material shape and inconsistent particle sizeASR often consists of lightweight, flexible, and sheet-like materials. Uneven particle sizes after shredding can impact the efficiency of

Hammer Crusher — High-Efficiency Crushing Solution
In the field of solid waste recycling and resource utilization, the crushing stage directly affects system efficiency and material recovery rates. GEP ECOTECH's hammer crusher, with its powerful impact force, robust structural design, and high crushing efficiency, has become the ideal equipment for industrial solid waste, end-of-life vehicles and metals, and lightweight mineral slag — enabling high-efficiency crushing and fine material processing.Working PrincipleThe hammer crusher consists of a casing, rotor, hammers, liners, and screen plates. Material enters the crushing chamber from the top and is crushed by the impact, shear, and grinding actions of the high-speed rotating hammers. Material meeting the target particle size passes through the screen plates, while oversized material continues to be crushed until it reaches the required size.With an optimized rotor and hammer arrangement, the machine maintains stable crushing force and consistent output particle size at high rotational speeds, reducing

RDF Bulk vs. RDF Pellets: GEP ECOTECH Comprehensive Analysis and Optimal Solution Customization
With the globalization of carbon emission reduction targets, the utilization of waste resources has become an indispensable part. Refuse-Derived Fuel (RDF) is receiving increasing attention as a key technology for transforming household waste from a "burden" to a "green energy". However, when planning RDF projects, companies face a core decision: should they produce RDF bulk materials or further process them into RDF pellets?There is no single answer to this choice, as it profoundly affects the investment return, operational model, and market prospects of the project. RDF bulk materials are known for their low initial investment and specific industrial application scenarios, while RDF fuel rods demonstrate enormous commercialization potential due to their high energy density, excellent storage and transportation performance, and wider market adaptability. As a complete solution expert in the field of solid waste treatment and resource utilization, GEP ECOTECH will deeply analyze the advantages and

The Ultimate Guide to Roller Screens: Function, Application, and Selection
Roller screen is a widely used pre-treatment screening equipment in industries such as mining, coal, electricity, and building materials. It is known for its sturdy structure, large processing capacity, and particularly good at handling sticky and wet materials. Below, we will help you sort out the common knowledge about roller screens from five aspects: working principle, main functions, production capacity, application field, and applicable materials, so that as your reference when purchasing equipment and evaluating project requirements.Working PrincipleStructural composition: The roller screen is mainly composed of multiple parallel arranged screen shafts, screen discs (or screens) installed on the screen shafts, transmission devices (motors, reducers), boxes, and brackets.Movement mode: Each sieve shaft is driven by a transmission device to rotate in the same direction. The installation method between the sieve shafts allows the sieve plates on adjacent sieve shafts to be arranged in a staggered manner

Application Scenarios and Selection Recommendations for Impact Crushers and Cone Crushers
Choosing between impact crushers and cone crushers in the mining and construction waste disposal industry is a critical decision that impacts investment, operational costs, and final product returns. First, let's clearly define their roles: both are typically used in the second and third stages of crushing, positioned after jaw crushers (primary crushing). We will provide a detailed analysis of their applications and selection recommendations from three aspects: principles, advantages and suitable scenarios.Impact CrusherWorking Principle:The impact crusher utilizes impact energy to break materials. The high-speed rotating rotor drives the hammer plates, striking the material entering the crushing chamber. The material gains kinetic energy and is thrown toward the impact plate for further collisions. Simultaneously, the material particles collide with each other repeatedly until they meet the required particle size and are discharged through the outlet.Advantages:Excellent finished particle shape: Due to the
