Sand Belt Conveyor

Ruiou's foundry sand belt conveyor is a purpose-built molding sand conveying solution for the Black Area of lost foam casting (LFC) production lines and foundry sand processing plants. Handling up to 30 tons per hour of dry, unbonded silica sand or pearl sand, this heavy-duty sand belt conveyor is engineered to provide continuous, stable, and spillage-free transport between shakeout stations, screening conveyors, sand coolers, and sand storage hoppers — forming the backbone of any reliable LFC sand recirculation system.

1. Main technical parameters

Sand flow rate: 20m ³/ H (20-30 mesh quartz sand or pearl sand)

2. Product structure

① Belt frame body.

② 2 drums (including 1 electric drum, 1 driving drum, 4 sets of tensioning bolt devices, and 4 bearings).

③ Edge blocking rollers (quantity depends on the length of the conveyor belt).

④ Combination of upper and lower rollers (quantity depends on the length of the conveyor belt).

⑥ Conveyor belt B=650mm/800mm (length subject to actual size).

3. Main functions and advantages

① The belt conveyor is mainly used to transport dry sand to the sand storage hopper, and its working environment temperature is generally limited to -10 ℃ to+100 ℃. It cannot be used to transport materials with strong acid, strong alkali, oily substances, and organic solvents. Can be used for horizontal or inclined conveying.

② Specially designed for the transportation of casting sand, with stable operation and a three roller design, it can ensure that the sand does not scatter or overflow to both sides during the sand transportation process.

③ Simple structure, easy to use and maintain, produced according to national standards, ensuring product quality, and long service life.

④ It has multiple types of protection functions.

Product Structure:

Ruiou's sand belt conveyor is built from heavy-duty industrial components, designed to withstand the continuous duty, abrasive conditions, and elevated temperatures typical of foundry environments:

Belt Frame: Sturdy and durable, designed for long-term reliability.

Drums: Includes 2 heavy-duty drums (one electric and one driving), with tensioning devices and robust bearings.

Rollers: Edge blocking rollers and combination of upper and lower rollers prevent material spillage and ensure smooth operation.

Conveyor Belt: Available in multiple sizes, custom conveyor solutions are available to meet your specific sand transport requirements.

Key Features and Advantages:

Stable Operation:

The three-roller design ensures smooth, stable transport of sand without scattering or overflowing, even during high-capacity loads. This makes it the ideal choice for casting sand transportation in foundry environments.

Wide Temperature Tolerance:

Designed to withstand temperature extremes from -10°C to +100°C, our foundry sand conveyor delivers reliable performance across a variety of foundry processes.

Ease of Maintenance:

With a simple, low-maintenance design, our sand belt conveyors are easy to maintain, reducing downtime and extending the lifespan of your equipment.

Flexible Conveying Options:

Our sand transport system can be configured for both horizontal and inclined conveying, allowing you to integrate it seamlessly into your foundry's production line.

Safety Features:

Equipped with multiple protective functions to prevent malfunction and ensure the smooth operation of the system, even in challenging environments.

Applications of Sand Belt Conveyors:

Foundry Sand Systems

Designed specifically for molding sand, casting sand, and other granular materials, these conveyors are essential for foundry operations.

High-Capacity Transport

Capable of handling up to 30 tons per hour of sand, making it ideal for large-scale industrial operations.

Custom Sand Conveyors

Offering custom conveyor solutions tailored to your specific needs, ensuring optimal performance in your sand transport systems.

Lost Foam Casting Black Area — Sand Recirculation 

The foundry sand belt conveyor handles the horizontal and inclined transfer segments of this loop, forming the continuous transport backbone of the Black Area.

Shakeout Station to Screening Conveyor

Immediately after the casting is removed and the flask is emptied, recovered sand is deposited onto a sand belt conveyor for transfer to the screening conveyor (vibrating screen), where casting fragments, metal scraps, and coating debris are separated from the usable sand.

Sand Cooler Inlet and Outlet Transfer

The sand belt conveyor delivers hot sand to the cooler inlet and transports cooled sand from the cooler outlet to the magnetic separator or storage hopper.

Sand Storage Hopper Loading

The final transfer stage in the sand recirculation loop — delivering reclaimed, cooled, and screened sand from the magnetic separator to the elevated sand storage hopper, ready for the next pour cycle. This is often an inclined molding sand belt conveyor installation.

The Role of the Sand Belt Conveyor in a Lost Foam Casting Sand System

In a lost foam casting facility, the sand cycle is continuous and high-volume. After the casting is poured and solidified, the flask is tipped and the dry unbonded sand pours free. This recovered sand must then be transported through a sequence of processing stages before it is ready for reuse — and the foundry sand belt conveyor is the primary horizontal and inclined transport link connecting these stages.

A typical LFC sand processing flow where the sand belt conveyor operates:

Shakeout → Belt Conveyor → Screening Conveyor → Belt Conveyor → Sand Cooler → Belt Conveyor → Magnetic Separator → Belt Conveyor → Sand Storage Hopper → Sand Shower Feeder → Flask

At each horizontal or inclined transfer point in this loop, a molding sand belt conveyor provides the stable, continuous flow that keeps the entire sand recirculation system running at production speed. An undersized or unreliable conveyor at any point in this chain can bottleneck the entire Black Area operation.
