When designing a production line for recycling cullet, the choice between dry and wet processes is pivotal and involves various intricate parameters. Below is a detailed comparison of these processes in key aspects:
I. Wet Sorting for Moist Glass
Critical parameters considered during wet sorting for moist glass:
Sorting granularity > 8 mm: Ensures effective waste glass processing, maximizing production efficiency.
Take-out ratio: Controlled take-out ratios are crucial for process economy.
Reduced dust: Wet processes reduce airborne dust, creating a cleaner work environment.
Loss of labeled and dirty glass: fficiently separates labels and impurities, minimizing glass loss.
80% of input material can be sorted: Handles 80% of raw materials, supporting high-yield recycling.
Sorting efficiency greater than 90%: Ensures high sorting efficiency, guaranteeing recycling quality.
II. Dry Sorting for Dried cullet
Key considerations for dry sorting of dried cullet:
Sorting granularity > 2 mm: Ensures efficient sorting of smaller particles.
High investment cost: Requires multiple processing machines, leading to higher investment costs.
Strict equipment requirements: To ensure high operational efficiency, strict control over drying machines, organic material sorters, and dust removal systems is essential.
90% input material sorted: Capable of sorting 90% of raw materials, ensuring substantial recycling yield.
Sorting efficiency ＞90%: Guarantees sorting efficiency exceeding 90%, producing high-quality reusable products.
III. Recommendation
Considering the strengths and weaknesses of wet and dry methods, we recommend selecting based on specific production needs. Wet processes are ideal for moist environments, while dry processes are suited for higher investment returns. The final choice should consider investment costs, available resources, and production efficiency to achieve optimal recycling and reuse results.
