Green (Clay) sand mixer
Green sand mixer
1. Summary:
Green sand mixer is a critical piece of equipment in the foundry industry, used for preparing green sand(molding sand), a type of molding sand that is used to create molds for metal casting. The term “green” refers to the fact that the sand mold is not baked or cured; it is used in its natural, damp state.
2. Components and Operation:
- Mixing Chamber: The main component where the sand, clay, water, and additives are thoroughly mixed to create a uniform moldable material.
- Mixing Blades/Arms: These are the rotating parts within the chamber that churn and blend the materials. They are designed to ensure an even mixture and proper conditioning of the sand.
- Water System: This system adds the precise amount of moisture needed to achieve the desired sand properties. It can include spray nozzles or other water delivery methods.
- Discharge System: Once the molding sand is mixed, it is discharged through a system that delivers it to the molding line or storage.
3. Process: The mixing process involves several key steps:
- Loading: Sand, clay (typically bentonite), water, and any other additives are loaded into the mixer.
- Mixing: The blades or paddles within the mixer rotate, blending the materials until a homogeneous mixture is achieved. The mixing time and blade speed can be adjusted based on the specific requirements of the mold.
- Conditioning: During mixing, the sand is conditioned to have the right moisture content and plasticity, which are crucial for forming strong and stable molds.
- Discharge: The well-mixed molding sand is then discharged from the mixer and transported to the molding area.
4. Applications: Green sand mixers are essential in foundries for:
- Mold Making: Creating sand molds for casting ferrous (iron and steel) and non-ferrous (aluminum, bronze) metals.
5. Advantages:
- Consistency: Ensures uniform mixing of sand, clay, and water, resulting in consistent mold quality.
- Efficiency: Automates the mixing process, reducing labor costs and increasing production speed.
- Adaptability: Can be adjusted for different sand compositions and moisture levels to meet specific casting requirements.
- Quality Control: Advanced mixers with computerized controls offer precise monitoring and adjustments, leading to better control over the properties of the green sand.
6. Selection Considerations:
- Maintenance: Regular maintenance of mixing blades, motors, and control systems is essential to ensure efficient operation and longevity of the mixer.
- Capacity: The mixer should be chosen based on the volume of sand required for the foundry’s production needs.
- Safety: Proper safety measures, including guarding moving parts and providing training for operators, are crucial.
7. Conclusion:
Green sand mixers play a vital role in the foundry industry by ensuring the preparation of high-quality molding sand. Their ability to mix and condition sand efficiently and consistently makes them indispensable for producing reliable and precise metal castings.Steven Wang

Clay(Green) sand production line
Clay (Green) sand casting production line—Automatic molding & Pouring
1. Summary:
- Automatic Clay (green) sand molding pouring line is an advanced manufacturing system used in foundries to produce cast metal parts.
- The process utilizes green sand, which is a mixture of sand, clay, water, and other additives, to create sand molds for metal casting.
2. Components:
- Sand Preparation and Mixing System:
Sand Mixer: This machine mixes sand; clay; water; and other additives to produce green sand. The mixture must have the right consistency and properties for mold making.
Sand Conditioner: Ensures the sand has the correct moisture content and other properties before it is used in the molding process.
- Molding Machine:
Automatic Molding Machine: This equipment automatically compacts the green sand around a pattern to form the mold. The pattern can be made of metal, wood, or other materials and is typically mounted on a molding board or plate.
Pattern Removal: After the sand mold is formed, the pattern is carefully removed, leaving a cavity in the shape of the desired cast part.
- Core Making and Insertion (if needed):
Core Making: For complex shapes, cores made from sand and binders are created and inserted into the mold cavity to form internal passages or features.
Core Setting: These cores are placed into the mold before the two halves of the mold are closed.
- Mold Assembly:
Mold Closing: The mold halves (cope and drag) are assembled together. If there are any cores, they are positioned properly within the mold cavity.
- Pouring System:
Molten Metal Pouring: Molten metal is poured into the mold cavity through a gating system. This is often automated in an automatic line to ensure precise and consistent pouring.
Pouring Machine: An automatic pouring machine can be used to control the flow rate and amount of molten metal poured into each mold.
- Cooling and Solidification:
Cooling Line: The filled molds are allowed to cool and solidify as they move along a conveyor system. Cooling times vary depending on the type of metal and the size of the casting.
- Shakeout and Sand Reclamation:
Shakeout System: After the metal has solidified, the sand mold is broken apart (shaken out) to release the cast part.
Sand Reclamation: The used sand is processed to remove impurities and prepare it for reuse in the molding process.
- Finishing Operations:
Cleaning: The cast parts are cleaned to remove any residual sand and surface imperfections.
Inspection: Parts are inspected for quality and accuracy.
3. Advantages:
- Increased Efficiency: Automation reduces the cycle time for each mold, increasing the production rate.
- Consistency and Precision: Automated systems ensure consistent mold quality and precise control over the pouring process, resulting in higher quality castings.
- Labor Savings: Automation reduces the need for manual labor, lowering labor costs and reducing human error.
- Flexibility: Modern systems can be quickly reconfigured for different casting designs and sizes.
- Improved Working Conditions: Automation minimizes the exposure of workers to high temperatures and other hazardous conditions associated with foundry work.
4. Applications:
- Automatic green sand molding pouring lines are widely used in the automotive industry, machinery manufacturing, and for producing various metal parts such as engine blocks, cylinder heads, and various other complex castings.
In summary, an automatic green sand molding pouring line integrates advanced machinery and automation to streamline the process of creating high-quality metal castings efficiently and consistently.

No bake Sand molding process
No-Bake Sand Molding Process
Furan Resin Sand Mixer with Sand Storage Tanks,
Phenolic Resin Sand Molding Plant
No-bake is a casting process that involves the use of chemical binders to bond the molding sand. Sand is conveyed to the mold fill station in preparation for filling of the mold. A mixer is used to blend the sand with the chemical binder and catalyst. As the sand exits the mixer, the binder begins the chemical process of hardening. This method of mold filling can be used for each half of the mold (cope and drag). Each mold half is then compacted to form a strong and dense mold.
A rollover is then used to remove the mold half from the pattern box. After the sand has set, a mold wash may be applied. Cores, if required, are set into the drag and the cope is closed over the cores to complete the mold. A series of mold handling cars and conveyors move the mold into position for pouring. Once poured, the mold is allowed to cool before shake-out.
The shake-out process involves breaking the molded sand away from the casting. The casting then proceeds to a casting finishing area for riser removal, casting finishing and finalization. The broken pieces of molded sand are further broken down until the sand is returned to grain size. The sand can now be either reclaimed for reuse in the casting process or removed for disposal. Thermal reclamation is the most efficient, complete method of Nobake sand reclamation.
