Liming Heavy Industry LM Vertical Roller Mill Facilitates High-Value Utilization of Solid Waste Recycling

South Africa has a large stockpile of waste glass and has long been plagued by difficulties in waste absorption and insufficient value unlocking. A local enterprise focuses on high-value resource utilization of waste glass solid waste and plans to build a high-standard waste glass powder production line. After multiple rounds of technical verification and on-site inspections, the project finally selected Liming Heavy Industry LM Vertical Roller Mill as its core main equipment.

Waste glass has long been regarded as hard-to-dispose industrial residue and municipal solid waste. Its stockpiling occupies land space, and large volumes of waste glass end up incinerated or landfilled. This not only consumes precious land resources and brings potential environmental risks, but also wastes the recyclable silica-rich resources contained in glass. As a recyclable industrial raw material with stable chemical properties, glass can be processed into high-value glass powder via fine grinding. It is known as “urban mineral”with great exploitation potential.

In the transformation of waste glass from raw material to high-value products, grinding serves as the core link determining finished product quality and application value. Targeting the material characteristics of waste glass such as high hardness and strong abrasiveness, Liming Heavy Industry has developed a waste glass recycling solution centered on LM Vertical Roller Mill. Adopting integrated grinding, drying and classification processes, this system can stably produce standard glass powder ranging from 325 to 600 mesh. It suits large-scale processing of open-stock and high-moisture waste glass, and provides reliable raw material support for the high-value application of glass powder in the construction industry.

With stable chemical properties, waste glass micro-powder serves as an indispensable recycled resource in the green building materials system. As a supplementary cementitious material for cement and concrete, waste glass powder contains approximately 70% silicon dioxide, which can effectively improve the mechanical properties and durability of concrete. It can be used to manufacture new composite materials featuring thermal insulation, sound insulation and fire resistance. Besides, it is applicable to waterproofing and protection systems for underground projects, as well as the processing of artificial stone and building decorative products.

Processing Material: Waste Glass

Finished Fineness: 325 Mesh

Finished Product Application: Waterproof Materials / Admixtures

Equipment: Liming Heavy Industry LM Vertical Roller Mill

Using waste glass as raw material, the project maintains a stable finished fineness of 325 mesh. The glass micro-powder produced features uniform particle size and consistent purity, and serves as a high-quality admixture in waterproofing works, effectively enhancing the impermeability and weather resistance of waterproof materials. Since the production line went into operation, it has delivered triple value large-scale absorption of solid waste, green and low-carbon production, and increased economic benefits establishing a new benchmark for the high-value utilization of waste glass in the region.

Waste glass is hard and difficult to process, imposing stringent requirements on the stability and refinement of grinding equipment. The Liming Heavy Industry LM Vertical Roller Mill integrates grinding, drying, classification and conveying in one unit, requiring no additional drying equipment. To cope with the highly abrasive nature of glass, the mill roller sleeves and grinding table liners are made of special materials to effectively extend service life. The system is equipped with a fully automated intelligent control system, supporting remote operation and interlock protection for convenient operation.
