Shakeout Deck Attrition Mill Introduction
In modern foundries, resin-coated sand systems demand efficient recycling to maintain cost-effectiveness and environmental sustainability. The shakeout deck attrition mill serves as a critical link in this process, combining two core functions:
· Shakeout: Disintegrating cured resin sand molds to separate sand from binders and contaminants.
· Attrition: Cleaning reclaimed sand through abrasive action to restore its usability. This machine ensures high-quality sand reuse, reducing raw material waste and energy consumption.
The shakeout deck attrition mill is a highly efficient and essential machine in the resin sand reclamation line, designed to perform two critical tasks: disintegrating sand molds (shakeout) and cleaning reclaimed sand (attrition). It plays a pivotal role in ensuring the quality and reusability of resin-coated sand in foundries.
What is a Shakeout Deck Attrition Mill?
A shakeout deck attrition mill combines the functions of a vibratory shakeout table and an attrition device. The shakeout deck breaks the mold and separates the casting from the sand, while the attrition mill rubs sand grains against each other to remove residual resin film and binder. This process prepares the sand for reuse in the molding system with minimal binder content and high thermal stability.
Core Functional Mechanisms
The mill operates through synergistic mechanical processes:
Structure and Working Principle
1. Shakeout Deck:
- Vibrates to disintegrate hardened resin sand molds.
- Separates castings and lumps of sand.
- Screens larger particles for further crushing or handling.
2. Attrition Mill Chamber:
- Equipped with rotating or vibrating paddles and abrasion liners.
- Sand particles collide and rub against each other, removing resin coating.
- Cleaned sand exits through the discharge for screening and reuse.
Key Features
- Dual-function machine: Combines shakeout and attrition in a single unit.
- Heavy-duty construction: Handles hot and abrasive sand with durable liners.

- Heavy casting production lines with large molds
Why Choose a Shakeout Deck Attrition Mill for Your Foundry?
In today’s competitive foundry industry, efficiency, sustainability, and casting quality are key to success. One of the most effective ways to improve all three is by implementing a shakeout deck attrition mill into your resin sand reclamation line. This dual-function machine provides both shakeout and sand cleaning in a single system—making it a smart investment for any modern foundry.
1. Two Processes in One Machine
A shakeout deck attrition mill combines the shakeout function—breaking down molds and separating castings—with mechanical attrition, which scrubs off the residual resin binder from used sand. This integration streamlines your sand reclamation process and reduces the need for separate equipment.
2. High-Quality Reclaimed Sand
Attrition mills restore sand to a condition that closely resembles new sand by removing resin coatings from each grain. Cleaned sand improves mold integrity, reduces casting defects, and enhances surface finish. This leads to better overall product quality.
3. Cost Reduction
Reusing reclaimed sand significantly cuts down the consumption of fresh sand and binder materials. A shakeout deck attrition mill maximizes your return on materials while lowering waste disposal costs.
4. Improved Environmental Compliance
Foundries face increasing pressure to reduce emissions and waste. By reclaiming and reusing sand, a shakeout attrition system supports environmentally friendly operations and helps you meet local regulatory standards.
5. Compact and Efficient Design
Instead of using multiple machines for shakeout and attrition, a single integrated unit saves floor space and simplifies material flow. It is ideal for foundries aiming for lean, organized production lines.
6. Durability and Low Maintenance
These machines are built for tough foundry conditions, with wear-resistant liners and heavy-duty construction that can handle hot, abrasive sand. Designed for long-term operation, they minimize maintenance and downtime.
7. Increased Productivity
Efficient sand separation and cleaning allow faster turnaround in the molding line. Clean sand is easier to mix and mold, improving process flow and reducing delays caused by poor sand quality.
8. Supports Automation and Modernization
The shakeout deck attrition mill can be seamlessly integrated into automated sand handling systems, allowing you to modernize your operation and keep up with the demands of high-volume production.
Choosing a shakeout deck attrition mill for your foundry is not just about improving sand reclamation—it’s about transforming your entire operation. It helps you produce better castings, reduce operating costs, enhance sustainability, and future-proof your facility. Whether you run a large-scale foundry or a specialized casting shop, this versatile solution is a powerful upgrade to your resin sand molding line.
Advantages of Shakeout Deck Attrition Mill Over Other Shakeout Machines
In foundries using resin sand molding systems, the shakeout process is crucial for separating castings from sand molds and preparing the sand for reuse. While various types of shakeout machines are available—such as vibratory shakeouts, rotary drum shakeouts, and grid-type shakeout tables—the shakeout deck attrition mill offers a distinct competitive edge due to its dual-function capability and superior sand reclamation performance.
Below are the key advantages of a shakeout deck attrition mill over conventional shakeout machines:
1. Integrated Attrition and Shakeout Functionality
Unlike standard shakeout machines that only break molds and separate castings, a shakeout deck attrition mill combines shakeout with mechanical attrition, scrubbing resin-bonded sand grains to remove the residual binder. This means you get both mold separation and sand reclamation in a single machine, reducing equipment footprint and process complexity.
2. Improved Sand Reclamation Efficiency
Standard shakeout machines do not clean the sand; they merely dislodge it from the casting. In contrast, the attrition section of the shakeout deck attrition mill cleans the sand surface, allowing up to 90–95% binder removal, which greatly improves the quality of reclaimed sand for reuse.
3. Lower Operational Costs
Because it reclaims sand more effectively, the shakeout deck attrition mill reduces the demand for new sand and fresh resin binders. It also eliminates the need for a separate attrition machine, reducing equipment investment, energy consumption, and maintenance costs.
4. Better Casting Surface Finish
Clean, resin-free sand produces smoother mold surfaces, which results in fewer casting defects, better dimensional accuracy, and improved surface finish. Conventional shakeout machines do not offer this benefit since they don’t reclaim or clean the sand.
5. Space-Saving Design
In foundries where floor space is limited, a combined shakeout and attrition system eliminates the need for separate machines, freeing up valuable space and enabling a more compact, efficient production layout.
6. Environmentally Friendly
Conventional shakeout machines contribute to higher volumes of used sand waste. In contrast, the shakeout deck attrition mill promotes sustainability by reclaiming sand in-house, reducing waste disposal volumes and helping meet environmental regulations.
7. Enhanced Productivity and Process Flow
With less need to transfer material between separate shakeout and reclamation units, the integrated system streamlines material handling, shortens cycle times, and enables more continuous operation with minimal interruption.
While traditional shakeout machines serve a basic function in separating castings from sand molds, the shakeout deck attrition mill goes further—combining shakeout and reclamation in one step to improve sand quality, reduce costs, and boost foundry efficiency. For resin sand foundries aiming to modernize, minimize waste, and enhance quality, the shakeout deck attrition mill offers clear and measurable advantages over conventional shakeout systems.
Conclusion
The shakeout deck attrition mill is an indispensable machine for modern foundries focused on resin sand reclamation. By combining the disintegration of spent molds with the mechanical cleaning of sand grains, it significantly enhances sand reuse, reduces operational costs, and supports environmentally responsible casting processes. For foundries seeking efficient and sustainable sand handling solutions, this system is a smart investment.
