Sand Recovery and Preparation Systems
Green sand casting is the most widely adopted method in the global foundry industry, and it begins with precise sand preparation. TES-SAN designs and manufactures complete sand recovery and sand preparation systems that cover every stage of the green sand casting process — from sand reclamation and cooling to mixing, conditioning, and automatic dosing.
Sand casting products and sand casting parts demand consistent sand quality. TES-SAN's sand casting equipment controls the critical variables of the sand casting process: moisture content, compactability, permeability, and green strength. Whether you operate a small jobbing foundry or a high-volume sand casting foundry processing sand casting steel or gray iron, the right sand preparation system directly determines your casting yield and surface quality.
As a sand casting equipment manufacturer based in Turkey, TES-SAN delivers turnkey sand preparation systems with complete engineering support. The product range covers every application within the green sand casting process and resin sand preparation — from portable mixers for core shops to rail-mounted and hydraulic piston mixers for high-volume operations. Sand casting foundry operators benefit from in-house engineering, domestic stock availability, and post-commissioning technical service.
Why Sand Recovery Systems Matter in Foundry Operations
Spent foundry sand recovery reduces raw material costs and supports environmental compliance. TES-SAN sand recovery systems use mechanical and pneumatic methods to strip binder residues from used sand, returning it to the sand preparation loop. Higher recovery rates translate directly into lower operating costs per ton of sand casting products produced. The sand casting method's economic viability depends heavily on efficient sand management — TES-SAN systems are engineered with this principle at their core.
Turnkey Sand Preparation System Projects
TES-SAN manages the complete project lifecycle: process analysis, engineering design, equipment supply, mechanical installation, electrical and automation integration, commissioning tests, and operator training. Turnkey sand casting equipment projects range from single mixer installations in small sand casting foundries to fully automated sand loops processing hundreds of tons per hour for sand casting steel and gray iron foundries. Every project is delivered under single-source responsibility.
Frequently Asked Questions (FAQ)
What is the difference between sand recovery and sand preparation systems? |
| Sand recovery systems reclaim spent foundry sand through thermal or mechanical processes, removing binder residues and contaminants so it can re-enter the production loop. Sand preparation systems then condition that reclaimed (or new) sand — adjusting moisture, clay content, and additives — to meet the full specification of the green sand casting process. TES-SAN manufactures equipment for both stages and integrates them as a single turnkey system. |
Which mixer is suitable for the green sand casting process? |
| For the green sand casting process, the Double Arm Screw Mixer or Double Arm Belt Mixer combined with an Automatic Dosing System delivers homogeneous mixing of sand, bentonite clay, water, and additives. The Hydraulic Piston Mixer is the correct choice for high-viscosity resin sand casting applications. TES-SAN engineers specify the optimal configuration based on your sand casting foundry's capacity and sand type. |
What factors influence sand casting equipment selection? |
| Key selection factors include hourly throughput capacity (tons/hour), sand type (green sand or resin), required automation level, floor space constraints, and integration with existing sand casting foundry conveying and cooling systems. TES-SAN performs an on-site process analysis before specifying equipment to ensure the sand casting process requirements are fully met. |
Does TES-SAN supply complete turnkey sand preparation systems? |
| Yes. TES-SAN delivers fully integrated turnkey sand preparation systems covering engineering design, equipment supply, installation, commissioning, and operator training. Project scope ranges from standalone sand casting equipment (single mixer plus dosing unit) to complete closed-loop sand management systems for large-scale sand casting foundry operations. |
What sand casting products and parts can be produced using TES-SAN-prepared sand? |
| TES-SAN sand preparation systems support production across all major foundry applications: sand casting products in the automotive sector (engine blocks, housings, manifolds), agricultural machinery sand casting parts, construction equipment components, and sand casting steel structural parts. The systems are equally effective for gray iron, ductile iron, aluminum, and steel casting. |
People Also Ask (PAA)
What is the green sand casting process?
The green sand casting process uses a mixture of silica sand, bentonite clay, water, and additives to form disposable molds. The term 'green' refers to the moisture content present in the mold at the time of casting, not its color. It is the most cost-effective sand casting method for high-volume production of sand casting parts and is widely used for sand casting steel, iron, and non-ferrous alloys.
What sand casting equipment does a foundry need?
A complete sand casting foundry requires a sand mixer (screw, belt, or hydraulic piston type), an automatic dosing system for binder and additive control, sand testing equipment, and a sand cooling and transport system. TES-SAN supplies the full range of sand casting equipment for both green sand casting process lines and resin sand casting foundry operations.
How does the sand casting method compare to other casting processes?
The sand casting process uses disposable compacted-sand molds, making it the most versatile casting method for complex geometry and a wide range of part sizes. Compared to die casting or investment casting, the sand casting method offers significantly lower tooling costs and greater flexibility for sand casting steel, iron, and aluminum — making it the dominant choice for sand casting foundry operations worldwide.
