Liujing Technology Group is one of the few high-tech enterprises in China with independent intellectual property rights and the ability to fully process both organic and inorganic waste sand. A highly intelligent, standardized, and systematic "one-stop", "fully utilized", and "near zero emission" waste sand regeneration and solid waste treatment process can regenerate old sand generated by molding and casting processes such as cold core, coated sand, and resin sand (including waste cores and old sand generated by core making, molding, sand treatment, and cleaning engineering departments), and provide excellent raw sand or coated sand for recycling by casting enterprises. While reducing customer procurement costs, it achieves the goal of green casting industry.
Technical features and advantages
● Efficient and energy-saving: Advanced roasting and grinding technologies are adopted to improve the regeneration efficiency of waste sand while reducing energy consumption.
● Environmentally friendly and pollution-free: The entire process achieves waste reduction, resource utilization, and harmless treatment, which meets national environmental protection requirements.
● High degree of automation: By adopting an intelligent control system, fully automated production from sand addition to finished products has been achieved, reducing labor costs.
● Superior product performance: Recycled sand has better performance than raw sand and can meet the demand for sandy materials in different fields. Recycled waste sand from wet molds can be 100% used for cold core production.
