Brief Introduction to Solid Waste Treatmment
The working principle of solid waste treatment technology applied in subgrade filling is to reconstruct the particle composition and structural characteristics of solid waste materials through a crushing machine, so as to meet the technical standards for highway subgrade filling materials. Researches show that when construction solid waste is crushed by an aggregate crushing machine to a particle size range of 0～60 mm, the interlocking effect and friction between particles reach an optimal balance, forming a stable skeleton structure. Optimally crushed construction solid waste materials achieve a California Bearing Ratio (CBR) of over 80%, fully satisfying the strength requirements of expressway subgrades.
Ninon Solid Waste Treatment Equipment Technology
The crushing technology of Ninon solid waste treatment equipment adopts professional crushing machines such as jaw crushers, hammer crushers and VSI crushers to apply strong mechanical force to solid wastes, so as to crush them into fine particles. The core of Ninon's solid waste treatment lies in the high-efficiency operation of the crushing machine, which ensures the stability of the crushing effect.
Ninon's solid waste treatment equipment, equipped with a high-performance aggregate crushing machine, reduces the material porosity to below 18% through gradation optimization, with the CBR value reaching 85%–90%. It not only improves material properties but also expands the application scope of construction solid waste. After reasonable proportioning, demolition waste with diverse sources and components can fully meet the technical standards for subgrade filling materials, relying on the reliable performance of the crushing machine in solid waste treatment.
Adopting a special curing agent enables convenient construction via two processes: dry spreading and premixing. The generated compounds effectively fill material pores. Meanwhile, the quality monitoring platform developed by Ninon for its solid waste treatment equipment—integrated with the crushing machine and aggregate crushing machine—based on Internet of Things (IOT) technology realizes digital and intelligent management of the entire subgrade construction process.

Through a comparative analysis with traditional sand and gravel subgrade, construction solid waste fillers processed by the aggregate crushing machine present prominent economic advantages. In terms of material cost, on-site demolition waste is recycled to eliminate raw material procurement expenses, with only the operation cost of the crushing machine for solid waste treatment required. Comprehensive calculation shows that the cost per cubic meter of filler can be reduced by 35%. From the perspective of resource conservation, the mining volume of natural sand and gravel can be decreased by 35,000 tons per kilometer of subgrade, equivalent to protecting 1333 m² of mine land, which fully reflects the environmental value of the crushing machine and aggregate crushing machine in solid waste treatment.
