Sand Recovery Systems are industrial plants that enable used foundry sand to be cleaned from binder residues through mechanical, pneumatic, or thermal methods and reintroduced into the production loop. The Low Level Reclamation system manufactured by TES-SAN is an integrated foundry equipment that efficiently converts shakeout molds back into reusable foundry sand.
The Low Level Reclamation system is a combined sand recovery plant consisting of a shakeout (sarsak), a vibrating elevator (vator), a cooler-classifier, and a pneumatic transporter. The system begins by breaking down the mold blocks after casting using mechanical vibrations.
Shakeout Unit (Sarsak): With its strong body design and Hardox-lined surfaces, it rapidly returns molds to sand form. The sand passes through 6 laser-cut sieves within the system to separate impurities.
Vibrating Elevator (Vator): Thanks to its 90-degree vertical design, this conveyor takes up minimal floor space while transporting the screened sand to the cooling section.
Cooler Classifier: Operating on a fluidized bed system with a combination of air and water cooling, it reduces the sand to the optimum usage temperature while highly separating internal dust.
Pneumatic Propulsion: Utilizing compressor air, it sends the regenerated sand back to the mixer lines with minimum energy consumption and low operating costs.
Selecting the correct sand reclamation plant directly influences the operational costs of foundry investments.
Low Level Reclamation: Easy to install, requires less vertical headroom, and is ideal for low-ceilinged facilities since the shakeout and transport units are combined into a compact structure. It features fewer parts requiring maintenance.
High Level Reclamation: These are large-scale tower systems where sand cascades downward by gravity, requiring higher ceiling clearance and deep foundations.
Sand recovery systems reduce raw foundry sand consumption by up to 90%. This directly lowers new sand procurement, transportation, and waste disposal expenses, ensuring a rapid return on investment (ROI).
TES-SAN offers a wide range of production, starting from the TRM3 model at 2-3 tons/hour up to the TRM12 model at 13-15 tons/hour. Table dimensions and pneumatic propulsion volumes are optimized based on project requirements.
All surfaces subjected to heavy friction by sand inside the shakeout and vator units are lined with high-strength Hardox material. A special welding process and heavy-duty vibro motors guarantee uninterrupted operation under harsh conditions.
The fluidized bed system precisely separates unwanted fine dust and resin residues using adjustable air flaps. Uniform cooling of the sand enhances the casting surface quality and minimizes scrap rates.
Yes, TES-SAN delivers turnkey services from initial feasibility studies to operator training backed by 30 years of engineering expertise. PLC-based automation systems are supported by remote monitoring infrastructure and a 100% domestic spare parts guarantee.
A pneumatic transporter moves sand through enclosed pipelines using compressed air instead of mechanical conveyors. This method prevents dust accumulation, saves plant space, and lowers operating costs by reducing moving parts.
Mechanical reclamation (Low Level) physically breaks the resin bonds around the sand grains and removes dust. Thermal reclamation burns off chemical binders entirely at high temperatures. Mechanical systems offer significantly lower initial investment costs.
The hourly sand processing capacity of the foundry, the type of resin used (furan, cold-box, etc.), factory ceiling height, and power infrastructure are the primary parameters. The TES-SAN technical team conducts on-site analysis to define the optimum setup.
