Current background

With the global installed capacity of photovoltaics breaking through the 1TW mark, the environmentally friendly treatment of retired photovoltaic modules has become a core proposition for the sustainable development of the industry. Monocrystalline silicon and polycrystalline silicon photovoltaic panels, as the mainstream of the market (accounting for over 90%), have driven the innovation of specialized equipment due to their efficient recycling needs. The monocrystalline silicon/polycrystalline silicon photovoltaic panel recycling pulverizer has become the core equipment for reconstructing the photovoltaic resource recycling chain through technological innovation.

Core principle

The solar photovoltaic panel silicon powder mill achieves efficient grinding and environmentally friendly treatment through the synergistic effect of mechanical force and intelligent control: the core of the equipment adopts a high-speed rotating grinding disc or roller structure. During operation, it gradually crushes the mixture of silicon material, glass fiber, and metal welding strip in retired photovoltaic panels into small particles through strong squeezing, shearing, and grinding actions. During the grinding process, friction between the grinding disc and the material generates heat. At this time, the built-in circulating cooling system will promptly dissipate excess heat to avoid damage to material properties caused by high temperatures. At the same time, the equipment is equipped with an efficient dust removal device, which captures the tiny dust generated by grinding through multi-layer filtration technology, ensuring that the emitted air cleanliness meets environmental standards

Unique design and advantages

Fully automatic framework design: Modular truss structure, supporting quick disassembly and horizontal adjustment, suitable for fixed production lines and mobile recycling scenarios.
Stainless steel cyclone separator: Using 304 stainless steel pipes, high-efficiency separation of silicon powder and impurities is achieved through cyclone centrifugation technology, with a separation efficiency of ≥ 99%, reducing material residue.
Water cooling cycle: covering the grinding chamber, feeding pipeline, and bearing seat, and exporting frictional heat through constant temperature coolant.
Air cooling assistance: Axial flow fans forcibly dissipate heat from the casing to ensure that the surface temperature of the equipment is ≤ 60 ℃ during continuous operation, preventing oxidation of silicon materials.
Dual mode sieve: standard 25 mesh (particle size ≈ 0.71mm) coarse sieve and 30 mesh (particle size ≈ 0.6mm) fine sieve, compatible with different particle size requirements.
Corrosion resistant design: Made of food grade materials, it can directly handle special materials such as fluorine containing backplates for photovoltaic panels.
Core component: Schneider contactor, equipped with digital ammeter and voltage monitoring module, real-time display of energy consumption data.
Brand guarantee: Using original bearings from France/Germany and undergoing special heat treatment, the service life is extended by three times compared to ordinary bearings.
Sealing performance: The double lip sealing structure effectively blocks the invasion of silicon powder, and the maintenance cycle is extended to 2000 hours.
