Sand Storage Hopper

In LFC black area, the sand storage hopper is used to store molding sand and continuously supply sand to the molding station. It is usually installed above or near the shower sand feeder, providing stable “bottom sand” and “cover sand” for the sandbox, and connecting to the sand processing system for circulation and cooling.

RUIOU’s LFC sand storage hopper is designed for dry sand conditions and negative-pressure pouring process. By coordinating with dust collection pipelines, level sensors and rain shower sand feeders, it helps ensure uniform sand filling, stable mold density and a cleaner working environment.

Sand Storage Hopper Structure

• Basic structure: cover plate, straight bucket (cylindrical or square), conical bucket, support columns; optional ladder and maintenance platform for safe inspection.

• Dust & environmental: upper feed inlet and lower sand outlet are designed to connect with dust removal pipelines; when matched with RUIOU dust removal system, it can significantly reduce dust in the workshop and improve labor conditions.

• Level & temperature monitoring (optional): high/low level sensors and temperature sensors can be added to avoid overflow or empty running, and to support cooling management in continuous operation.

• Discharge device: the hopper bottom is typically connected with RUIOU RO sand shower feeder or movable shower sand feeder to achieve uniform sand showering and precise control of sand volume for bottom and cover sand.

  
  

Product Performance and Characteristics:

1. Used to store molding sand, it provides enough sand for transfer and moulding. By connecting shower sand feeder or simple sand feeding device, it controls sand falling and moulding in LFC production.

2. Reasonable structure layout. The coordination of straight bucket and cone bucket can not only guarantee the quantity of sand storage, but also meet the requirements of moulding. It is also equipped with ladder and maintenance platform to facilitate production and maintenance.

3. Environmental protection dust-free, the upper feeding inlet and sand feeding inlet works with dust removal pipeline to ensure workers' operating environment.

Model Selection and Technical Parameters:

(Note: the specific model is based on the actual design.)

Performance & selection notes

• Buffer capacity: the effective volume is selected based on the line’s cycle time and sand consumption. For stable operation, the hopper capacity should ensure at least 10–20 minutes of molding sand buffer time to smooth out upstream fluctuations (screening, cooling, return sand).

• Sand quality protection: the inner wall can be equipped with wear-resistant lining (especially in the cone) to resist abrasion and impact from sand flow, extending service life and keeping sand clean.

• Anti-bridging design: the cone angle and discharge openings are optimized for dry sand; if necessary, pneumatic arch breakers or vibrators can be added to prevent bridging and ensure smooth discharge.

• Interface with sand processing: the hopper can be integrated with RUIOU sand process system (cooling, magnetic separation, screening, conveying) to form a closed-loop black area sand system with minimal sand loss and stable sand temperature.
