Is Your Foundry Throwing Away Thousands of Dollars in Usable Resin Sand?

Every day, foundries produce tons of used resin bonded sand after shakeout.

Many plants still dispose of large quantities of this material because the sand lumps are too large to be reused efficiently.

The result?

❌ High new sand consumption

❌ Expensive resin costs

❌ Increased waste disposal fees

❌ Low sand recovery rates

❌ Higher production costs

The good news is that most of this “waste sand” still contains valuable silica sand.

The challenge is not the sand itself—it is how efficiently you reclaim it.

This is why modern foundries install an Industrial Resin Sand Crushing Machine as the first mechanical stage of a complete resin sand reclamation system.

What Is an Industrial Resin Sand Crushing Machine?

Resin Sand Crushing Machine is designed to crush hardened resin-bonded sand lumps into reusable sand particles before secondary reclamation.

Unlike ordinary crushers, this machine is engineered specifically for foundry applications.

It provides controlled crushing while protecting the original sand grains from excessive breakage.

The processed sand can then enter:

• Mechanical reclamation machines
• Thermal reclamation systems
• Sand screening equipment
• Sand cooling systems

for further cleaning and reuse.

Why Crushing Is the Most Important Step in Resin Sand Reclamation

Many foundries focus only on secondary reclamation equipment.

However, if large sand lumps are not properly crushed first, downstream equipment cannot operate efficiently.

Typical problems include:

Poor Sand Recovery

Large agglomerates reduce reclaim efficiency.

High Resin Residue

Binder cannot be removed effectively.

Equipment Wear

Oversized lumps overload reclaim machines.

Higher Energy Consumption

Downstream equipment works harder while producing lower-quality reclaimed sand.

Proper crushing solves these problems before they occur.

How the Resin Sand Crushing Machine Works

Step 1: Feeding Used Resin Sand

Large resin sand blocks enter the crushing chamber directly from:

• Shakeout machines
• Sand collection conveyors
• Return sand systems

Step 2: Controlled Crushing

Wear-resistant crushing rollers or impact components gradually reduce the sand lumps into smaller particles.

The crushing force is optimized to:

• Break resin bridges
• Preserve silica grains
• Minimize excessive fines

Step 3: Uniform Particle Size

The crushed material reaches a consistent particle size suitable for downstream reclamation.

Oversized particles remain inside the crushing chamber until properly processed.

Step 4: Material Discharge

Processed sand moves automatically to:

• Mechanical reclamation units
• Fine hexagonal screens
• Cooling beds
• Dust collection systems

Step 5: Complete Reclamation Process

After crushing, reclaimed sand undergoes:

• Friction scrubbing
• Dust removal
• Screening
• Cooling

before returning to the molding process.

Technical Parameters

Machine specifications can be customized according to foundry production capacity.

Key Advantages of an Industrial Resin Sand Crushing Machine

1. Maximize Sand Recovery

Efficient crushing allows downstream reclamation equipment to remove residual binder more effectively.

Benefits include:

✅ Higher reclaim rates

✅ Lower new sand purchases

✅ Better utilization of existing resources

Many customers achieve:

90–98% reusable sand recovery.

2. Reduce Raw Material Costs

New silica sand prices continue to increase worldwide.

Higher reclaimed sand usage means:

• Lower sand purchasing costs
• Lower transportation costs
• Reduced inventory requirements

3. Improve Reclaimed Sand Quality

Uniform particle size improves:

• Core strength
• Mold strength
• Sand flowability
• Surface finish

This leads to more consistent casting quality.

4. Lower Equipment Wear

Proper pre-crushing reduces the load on:

• Mechanical reclaimers
• Thermal reclaimers
• Screens
• Conveyors

This extends equipment life and reduces maintenance costs.

5. Support Fully Automated Sand Reclamation

The machine integrates seamlessly into:

• Resin sand reclamation plants
• Automatic sand handling systems
• Intelligent foundry production lines

enabling continuous, automated operation.
