Product Description
Core shell sand thermal reclamation lines are specialized systems for recycling used core - shell sand in foundries, which mainly rely on high - temperature calcination to decompose and remove residual binders on the sand surface, enabling the reclaimed sand to meet the requirements of remaking core - shell sand, thereby reducing new sand consumption, lowering production costs, and minimizing environmental pollution. The following is a detailed breakdown of its application, composition, and capabilities.
Applications
Core shell sand thermal reclamation lines are mainly applied in foundries that use core - shell sand for core - making and molding, especially in the following fields:
- Automotive Industry: For manufacturing engine components, such as cylinder heads, intake manifolds, and valve seats, which require high precision, good surface finish, and complex internal structures.
- Aerospace Industry: Suitable for producing castings with high - performance requirements, like turbine blades, aircraft engine casings, etc., which demand high - temperature resistance and dimensional stability.
- Precision Machinery: Used for casting precision parts such as gears, bearings, and hydraulic components, where strict control over casting defects is essential.
- General Foundry Production: Applicable to castings of various materials, including steel, iron, aluminum alloys, etc., particularly those with high requirements for core strength, collapsibility, and casting surface quality.
Composition
A typical core shell sand thermal reclamation line is a continuous and automated system composed of the following key components:
| Component | Function |
|---|---|
| Shakeout and Crushing Unit | Breaks down the used core - shell sand after casting, separates castings from the used sand, crushes large sand lumps, and conveys the used sand to the subsequent process |
| Magnetic Separator | Removes iron impurities from the used sand to prevent them from affecting the quality of reclaimed sand and castings |
| Screening Equipment | Screens the sand to ensure uniform particle size and remove large debris |
| Calcining Furnace (Core Component) | Heats the used sand to 500-800°C to decompose and burn off organic binders on the sand surface. Common types include fluidized - bed furnaces and rotary drum furnaces, which ensure uniform heating of sand particles |
| Cooling System | Cools the high - temperature reclaimed sand after calcination to the temperature required for core - making (usually below 50°C). Fluidized - bed coolers or water - cooled + air - cooled combined coolers are often used |
| Air Classification and Dust Removal System | Removes fine powder and dust from the reclaimed sand through cyclones and pulse dust collectors, improving the sand quality and meeting environmental emission standards |
| Sand Storage and Conveying System | Stores qualified reclaimed sand and conveys it to the core - making process as needed |
| PLC Control System | Achieves automatic control of the entire line, including parameters such as calcination temperature, sand feeding speed, and cooling temperature, to ensure stable operation |
Capabilities
- High Reclamation Rate: The reclamation rate can reach 90% - 98%, significantly reducing the demand for new sand and the cost of waste sand disposal.
- Excellent Binder Removal Effect: The binder removal rate is over 95%, and the reclaimed sand has stable physical and chemical properties, low ignition loss, and good particle - size distribution, which can ensure the quality of remade core - shell sand and castings.
- Stable Sand Performance: The reclaimed sand has similar properties to new sand, with good thermal stability and fluidity, ensuring consistent core strength and collapsibility, and reducing casting defects such as gas holes and sand sticking.
- Energy - Saving and Environmental Protection: Equipped with heat exchangers to preheat combustion air using waste heat from hot sand, reducing energy consumption. The dust removal system ensures that exhaust emissions meet national standards, reducing environmental pollution.
- Strong Adaptability: Can handle used core - shell sand with different degrees of binder content and sand temperatures. It can also be combined with mechanical reclamation to further improve the sand reclamation effect. The production capacity can be customized according to the foundry scale, generally ranging from 1 to 20 t/h.
- Automation and Intelligence: The PLC control system realizes automatic operation, reducing manual intervention, improving production efficiency, and ensuring the stability of the reclamation process.
