Leelink Resource Technology Co., Ltd is committed to the circular economy. We convert waste from non-metal refractory materials into high-value raw materials and creative products in a low-carbon-emission and sewage-free recycled manner.
Recycled Malay Sand
Our innovative material features an exclusive patented process that reduces carbon emissions by 90% compared to original ore sand. The grains are smooth, ensuring good air permeability and a low dust content. With high refractoriness and excellent resistance to thermal shock, this material is designed for demanding applications. Additionally, it boasts stable physical and chemical properties, a low expansion coefficient, and high volume stability, making it a reliable choice for various industries.

Recycled silica sand
Our advanced material features round and breathable particles that enhance airflow and performance. With a small expansion coefficient and good volume stability, it maintains its integrity under varying conditions. Additionally, it contains iron oxide, which improves the strength of the sand core and facilitates the collapse of the sand mold during demolding, ensuring efficient production processes.

Recycled Castable Refractory Clay
Our product is composed of various refractory raw materials as aggregates, combined with a precise amount of high-aluminum cement. It is provided as a dry material, which requires the addition of water during construction for mixing. Utilizing diverse construction methods such as pouring, painting, and plastering, this material is effectively cast into a solid refractory body, making it ideal for high-temperature applications.

Integrating Materials and Expanding Recycling
Integrating material characteristics with industry demands, we not only reverse cycle waste foundry sand back into the original manufacturing processes of the foundry industry but also continuously expand the diversity of recycled products, making the circular economy platform for refractory material waste more comprehensive.
