Product structure

Main functions and advantages

Function: Cooling and sand storage. The sand drop device adopts a plug-in method, and the switch of the sand drop device is automatically controlled through PLC and temperature detection device. The sand drop device can only be opened after meeting the sand temperature requirements, ensuring that the molding sand meets the usage temperature. And it can be linked and controlled with the front and rear equipment to ensure the sand temperature of the production line and the normal application of other equipment.

Energy saving: This equipment does not require power and uses cooling water equipped on the production line. The molding sand wriggles downwards by gravity, achieving the goal of controlling the sand temperature by controlling the falling process.

No noise: As the equipment does not require power, the molding sand wriggles downwards, so there is basically no noise during use.

Low one-time investment in equipment: The sand temperature regulator is compatible with sand storage and cooling functions, and the cooling process can store a certain amount of molding sand, providing support for the operation of the production line.

Node temperature control, effective detection and control of sand temperature: The equipment controls the sand outlet through the sand temperature detection device. Only when the molding sand meets the usage requirements can the plug-in board be opened and the molding sand be transported, effectively ensuring the temperature of the molding sand.

The equipment has no vibration, a solid structure, and stable operation, greatly reducing the failure rate of the equipment. The sand temperature regulator uses closely arranged seamless steel pipes to achieve sand heat exchange, with a large contact area and high cooling efficiency.

Our sand cooling machine a type of lost foam casting equipment, is specially designed for high-efficiency sand cooling, continuous operation, and long-term reliability in industrial foundry environments.

• Stable Temperature Control
  Water ring circulation ensures uniform sand cooling, effectively preventing temperature fluctuation and improving molding quality.

• Efficient Heat Exchange
  Optimized water–sand contact design delivers fast heat dissipation with low energy consumption.

• Reliable & Continuous Operation
  Designed for long-term, high-load foundry environments with stable performance and minimal downtime.

• Flexible System Integration
  Easy to integrate into existing sand preparation lines or complete foundry production systems.

• Low Maintenance Design
  Simple structure, corrosion-resistant components, and reduced maintenance cost over the equipment lifecycle.

Application in Lost Foam Casting Production Lines

This sand cooling machine is widely used in:

• Lost foam casting sand recycling systems

• Sand circulation and cooling units

• Mold filling and compaction processes

• Continuous production workshops

It effectively reduces reclaimed sand temperature and stabilizes sand performance before reuse.

Working Principle

The sand cooling machine adopts a rotary drum cooling structure combined with air cooling and material lifting mechanisms.

During operation:

• High-temperature reclaimed sand enters the cooling drum

• The drum rotates continuously to ensure uniform mixing

• Internal lifting plates improve heat exchange efficiency

• Cooling air flows through the sand layer

• Cooled sand is discharged for further screening and reuse

This design ensures stable cooling performance and uniform temperature reduction.

Integrated System Compatibility

The sand cooling machine can be seamlessly integrated with:

• Vibrating sand screening machines

• Dust collection systems

• Sand storage hoppers

• Conveying and lifting equipment

• Centralized control systems

It supports full-line automation and intelligent sand management.
