Reduce New Sand Consumption
Recover valuable silica sand from waste green sand and reduce dependence on new sand.
03 / SAND RECLAMATION
Green Sand Reclamation
Turn Waste Green Sand Back into High-Value Foundry Sand
LANCO combines pretreatment, thermal regeneration and intensive post-treatment to remove clay, fines and combustible residues from waste green sand and restore sand quality for foundry reuse.

WHY LANCO GREEN SAND RECLAMATION
Recover the material.
Restore its value.
Reduce Waste Disposal
Convert waste sand from a disposal burden into reusable production material.
Create Higher-Value Reclaimed Sand
The combined regeneration process removes residual clay, fines and combustible material and improves reclaimed-sand quality.
PROCESS / FROM WASTE TO REUSE
A complete route back
to foundry production.
Mechanical preparation, thermal regeneration and intensive cleaning work together to address different residues on the sand.

THREE CORE TECHNOLOGIES
Each stage has
a specific job.
CORE TECHNOLOGY
Pretreatment / Sheller
Removes fines and preliminary surface impurities before thermal regeneration.
≥80%Impurity removal efficiency
Moisture content, equipment speed and treatment time inform the pretreatment setup.
CORE TECHNOLOGY
Thermal Regeneration Furnace
High-temperature regeneration removes combustible residues such as coal powder and resin film from the sand surface.
100%Combustible impurity removal
LOI ≤ 0.1%
CORE TECHNOLOGY
Intensive Grinding & Cleaning
Removes residual fine powder and clay after thermal regeneration and improves particle sphericity.
≤0.2%Silt content
ADV ≤ 6 mL/g
Performance depends on incoming sand condition and the configured treatment process. Project specifications are established during engineering evaluation.

APPLICATION EXPERIENCE
Developed Through
China’s Foundry Scale
China is home to one of the world’s largest concentrations of foundry production. LANCO’s Green Sand Reclamation technology has been developed and proven through repeated industrial applications across automotive, engine and heavy-industry foundries.
This application experience allows LANCO to engineer reclamation systems around different waste-sand conditions, capacities and reuse requirements.
CAPACITY / PROJECT REQUIREMENTS
Capacity for Industrial Reclamation
LANCO configures each Green Sand Reclamation plant according to waste-sand volume, sand condition, target reclaimed-sand quality and downstream reuse requirements.
