Description
Product Description
S37 Impact Sand Crusher
The S37 Impact Sand Crusher is a high-efficiency spent sand crushing machine specially designed for foundry applications. It is primarily used to break down compacted or lumped spent sand (e.g., clay-bonded, resin-bonded, or sodium silicate sand) discharged from shakeouts, sand bins, or conveyors into loose particles with a size of ≤30 mm, ensuring uniform and free-flowing feed for downstream processes such as cooling, screening, reclamation, and mixing.
Featuring a high-speed rotating impact plate + fixed anvil liner crushing mechanism, the S37 offers compact design, high capacity (30–50 t/h), and reliable operation—widely used in medium-to-large foundries for automotive, rail, ductile iron pipe, and heavy equipment manufacturing.
Working Principle
Feeding: Compacted spent sand enters the crushing chamber through the top inlet.

High-Speed Impact Crushing: The main shaft rotates at 800–1200 rpm, driving multiple high-manganese steel impact plates. Sand lumps are thrown outward by centrifugal force and violently collide with high-chrome cast iron anvil liners fixed on the housing—achieving multi-stage crushing through impact, shear, and rebound.

Particle Size Control: Crushed sand exits through a bottom adjustable grate screen, with particle size controlled by screen aperture (typically Φ20–Φ40 mm) for consistent discharge.

Overload Protection: Equipped with mechanical or hydraulic safety devices—automatically unloads or shuts down upon foreign object entry (e.g., metal pieces, casting scraps), protecting the main shaft and impact plates.

Key Features
High-Efficiency Crushing, Uniform Granularity
High-speed impact + multi-stage rebound mechanism crushes lumps up to 200 mm into ≤30 mm in one pass, with a crushing ratio up to 6:1—ensuring consistent output and no oversized residues.
Wear-Resistant Construction, Long Service Life
Impact Plates: ZGMn13 high-manganese steel, solution-treated for superior impact toughness
Anvil Liners: Cr26 high-chrome cast iron, hardness HRC≥58
Grate Screens: Wear-resistant alloy steel, reversible for extended use
Key wear parts last 8,000–12,000 operating hours.

Compact Design, Flexible Installation
Vertical layout with small footprint (~2.5 m²)—can be installed directly under shakeouts or sand bin outlets, saving floor space and enabling easy system integration.

Easy Maintenance, Efficient Servicing
Side-opening housing allows quick replacement of impact plates or screens without full disassembly. Centralized lubrication system for main shaft bearings—maintenance interval up to 500 hours.

Stable Operation, Low Noise
Dynamic balance grade G6.3 ensures minimal vibration. Standard sound enclosure keeps noise ≤85 dB(A), meeting workshop environmental standards.

Intelligent Monitoring (Optional)
Optional PLC system monitors motor current, bearing temperature, and vibration—automatically alarms and shuts down on anomaly, with remote data transmission capability.
