What Type of Equipment Do I Need For Recycling Asphalt Shingles?


Specialized equipment is necessary for recycling asphalt shingles. Horizontal grinders are central to this process, as they efficiently handle the density and abrasiveness of asphalt shingles.


Besides horizontal grinders, key equipment includes conveyors, shaker screens, density separators, and trommel screens. Conveyors facilitate the steady flow of shingles, while shaker screens and density separators clean and sort the material, removing contaminants. The discharge conveyor plays a crucial role in this process.


Each piece of equipment is crucial. Shaker screens ensure only appropriately sized materials proceed, and density separators remove debris. These machines work together to maximize efficiency and output, making asphalt shingle recycling both viable and profitable.


New vs. Used Shingle Grinders


Choosing between new and used shingle grinders involves several considerations. New grinders provide better reliability and performance, often featuring the latest technological advancements. They typically come with warranties, offering long-term security.


Used shingle grinders are attractive for their lower initial cost, but this can be offset by higher maintenance and repair expenses. These grinders often need more frequent repairs, affecting operational costs and efficiency. Weighing immediate savings against potential long-term expenses is crucial.


Ultimately, the decision should be based on your specific needs and budget. New grinders offer reliability and advanced features, while well-maintained used horizontal grinders can be a cost-effective solution.


Key Features in a Shingle Grinder


Choosing the right shingle grinder means looking for features that enhance performance and ease maintenance. A water spray system cools shingles before grinding, reducing wear in the grinding chamber. This prolongs the grinder’s life and ensures smoother operation.


Quick access to components like the rotor and screens minimizes maintenance downtime, enabling faster repairs and replacements. Effective shingle grinders usually operate within a horsepower range of 600 to 750, balancing power and efficiency.


Magnetic systems are crucial for removing nails and other ferrous metal materials from processed shingles. This ensures the quality of the recycled product and protects the grinder from metal damage. These features significantly impact performance and efficiency.


Essential Wear Parts for Shingle Grinders


Maintaining a shingle grinder’s efficiency involves paying attention to wear parts like rotor teeth and sizing screens. These components endure the grinding process and require regular replacement. Models like the RG-1 are designed for easy part replacement.


Manufacturer support is crucial for ensuring replacement parts are readily available, minimizing downtime and lost profits. A reliable source, such as GrinderCrusherScreen, for wear parts streamlines maintenance and keeps the grinder productive. Conducting daily inspections and following a preventative maintenance program prolongs the life of internal components.

Regular maintenance extends the lifespan of wear parts and ensures consistent production quality. Monitoring critical wear parts and maintaining strong manufacturer support maximizes the efficiency and longevity of grinding operations.


Specialized Shingle Grinding Equipment


Specialized equipment optimizes the shingle recycling process. Magnetic cross-belt magnets efficiently remove roofing nails and other ferrous materials, ensuring product quality and protecting the grinder from damage.


Mobile grinding services provide a flexible solution for shingle recycling, using custom equipment for on-site processing. This reduces transport costs and creates sellable products from materials otherwise destined for landfills. Municipalities benefit by adding a valuable revenue stream to their recycling programs.


Using existing site equipment and personnel, mobile grinding services reduce operational costs and enhance efficiency. Specialized equipment is essential for optimal results, making asphalt shingle recycling more efficient and economically viable.


Lowering Wear Costs


Lowering wear costs in shingle grinding is crucial for profitability. Addressing small issues promptly prevents costly breakdowns and maximizes productivity. This proactive approach ensures efficient operation, reducing downtime and maintenance costs.


Shingle grinding recycles materials and recovers about 25% oil, enhancing asphalt production’s economic viability. Using recycled materials in asphalt production reduces drying costs and preserves residual oils, lowering overall production costs.

Regular cleaning of components like sizing screens prevents buildup that hinders efficiency. Maintaining these components and promptly addressing wear can significantly reduce costs and ensure the longevity of grinding equipment.


End Product Quality and Precision


High-quality recycled asphalt shingles (RAS) are crucial for meeting performance standards. Precision in RAS processing directly influences asphalt mixture characteristics like durability and resistance. Shingle grinders are essential for producing RAS that meets strict specifications.


Grind size and consistency of shingles are critical for asphalt pavement quality. Multi-purpose horizontal grinders can also process yard waste and wood, providing versatility and broadening the uses of grinding asphalt shingles.


Quick screen changes at ground level minimize downtime and allow easy adaptation to different product specifications. The right screen configuration depends on the material and desired end product. Ensuring end product quality and precision is key to successful recycling operations.


The Role of Shingle Grinders in Asphalt Plants


Recycled asphalt shingles (RAS) are significant in asphalt plants, offering a cost-effective and eco-friendly alternative to virgin asphalt. Shingle grinders process asphalt shingle waste, recycling over 11 million tons of shingles annually and reducing landfill waste from roofing materials.


Efficient sorting is crucial for removing contaminants and ensuring high-quality recycling shingles material. In 2014, recycled shingles contributed 2 million tons to new pavements, saving over $2.8 billion. They are processed to a specific size and stored to maintain moisture control until used in asphalt mixes.


Partnering with asphalt plants streamlines the recycling process and reduces transport costs. Collaboration ensures a steady supply of high-quality recycled material, benefiting both parties and promoting sustainability.


Maintenance Tips for Maximizing Uptime


Regular maintenance maximizes the uptime productivity of shingle grinders. Regularly examining sizing screens is essential, as their condition affects the final product size and efficiency. Frequent checks of wear parts like rotor teeth and screens maintain production quality.


Regular inspections identify contaminants that cause wear and impact productivity. Monitoring the gap between the cutter and screen is important, as it can widen over time. Remote monitoring systems track wear parts’ lifespan and schedule timely replacements to avoid interruptions.


Rotochopper shingle grinders feature a high abrasion package and water spray system for enhanced durability and uptime. Flipping grinder screens when they start to wear extends their lifespan. Following these maintenance tips ensures consistent operation and lowers maintenance costs.
