Product Description
Product Description of Attrition Scrubber Regenerator
The Attrition Scrubber Regenerator is a high-efficiency sand reclamation device based on mechanical attrition and frictional peeling principles, specifically designed to remove residual fired binder films (resin, silicate, or coated layers) from used foundry sand. It is widely used in reclamation systems for no-bake resin sand, CO-silicate sand, and shell sand. Through intense rubbing, impact, and shearing between a high-speed rotor and wear-resistant liners, sand particles are stressed and abraded against each other, effectively stripping off inert surface layers. This restores the original activity and surface cleanliness of quartz sand, reducing Loss on Ignition (LOI) to ≤0.5%—meeting high-quality mixing process requirements.
With a capacity of 3–30 tons/hour, this machine is suitable for new green foundries, smart sand system upgrades, or retrofitting of outdated reclamation lines. It can be integrated with crushers, coolers, screens, magnetic separators, and dust collectors to form a complete sand reclamation line, achieving zero waste discharge and sand reuse rate ≥95%—significantly reducing raw sand consumption and solid waste disposal costs, supporting sustainable manufacturing.
Working Principle
1.  Feeding Stage
Used sand (typically after shakeout or primary crushing) is fed uniformly into the regenerator via belt conveyor or bucket elevator. Sand temperature should be ≤60°C to protect equipment and enhance reclamation efficiency.
2. Attrition Regeneration Stage (Core Process)
Sand enters the regeneration chamber formed by a high-speed rotor and wear-resistant liners. The rotor accelerates sand particles, causing intense impact and rubbing against the liners. Simultaneously, particles shear, abrade, and roll against each other under high stress, peeling off the sintered surface films. The process is dry reclamation—no water or chemicals required—making it energy-efficient and eco-friendly.
3.  Discharge & Dust Control
Regenerated sand continuously discharges from the bottom outlet to downstream cooling, screening, and magnetic separation processes. The fully enclosed design with a pulse cartridge dust collector efficiently captures dust, with emissions ≤5 mg/m³—compliant with national standards.
4. Intelligent Monitoring System
Optional vibration sensors, temperature sensors, and current monitoring enable real-time equipment status tracking, preventing overload or abnormal wear for long-term reliability.

Key Features
High Reclamation Rate, Superior Sand Quality
Regenerated sand LOI ≤0.5%, low gas evolution, excellent flowability—can replace 90–95% of new sand, significantly reducing raw material costs.
Dry Reclamation, Energy-Saving & Eco-Friendly
No water or chemicals required—zero wastewater; energy consumption 40–60% lower than wet reclamation—ideal for green foundries.
Robust Structure, Wear-Resistant & Durable
Rotor blades, liners, and housing use NM400 steel, ceramic composite, or tungsten carbide cladding—critical components last 1–3 years depending on conditions.
Easy Maintenance, Long Service Intervals
Features quick-opening inspection doors and modular liners—wear parts can be replaced without disassembling the entire machine, minimizing downtime.
Intelligent Control, Stable Operation
Optional PLC + HMI touchscreen enables start/stop, fault alarms, data logging, and remote monitoring—supports MES integration.
Versatile & Widely Applicable
Suitable for furan, alkaline phenolic, silicate, and shell sands—adaptable to various grain sizes and binder systems.
