EPS (Expanded Polystyrene) recycling machines are specialized equipment designed to process and recycle foam plastic waste. As global environmental awareness increases, EPS recycling technology has become a crucial solution for addressing packaging and construction waste challenges. This article provides a comprehensive analysis of the complete operational workflow of EPS recycling machines.
The Importance of EPS Recycling
EPS materials are widely used in packaging, insulation, and construction applications, but their composition of 98% air and only 2% polystyrene makes them bulky and expensive to transport. Traditional landfill disposal not only occupies substantial space but also causes long-term environmental pollution. Professional recycling can reduce foam waste volume by over 90%, significantly lowering transportation costs while converting it into high-quality reusable raw materials. EPS strojevi za recikliranje Main Types of EPS Recycling Equipment
The market offers three primary types of EPS recycling equipment, each suited for different application scenarios:
- Cold Press Compactors
- Hot Melt Densifiers
- Pelletizing Recycling Systems
Complete EPS Recycling Operational Workflow
Step One: Waste Collection and Sorting
The recycling process begins with collecting EPS waste from various sources, including packaging facilities, retail stores, construction sites, and manufacturing plants. After collection, waste must be sorted and cleaned to remove potential contaminants. Before feeding, it is essential to ensure removal of tape, plastic films, metals, and stones, as these materials can block filter screens or damage equipment crushers, screws, and cutters.
Step Two: Crushing Process
Sorted EPS waste is fed into specialized crushers for shredding. Crushers cut large foam materials into smaller fragments, typically 10-20mm in size. This step is crucial for subsequent melting and compaction processes, as smaller fragments are easier to handle in equipment and prevent long strips from tangling and blocking conveyor systems.
Step Three: Melting and Compaction
Crushed EPS fragments are fed into the core processing unit of the recycling machine. During this stage, equipment employs different processing methods based on type:
- Cold press equipment uses high-speed rotating screws (approximately 1000 RPM) to compress foam, forcibly expelling air and gradually compacting the material.
- Hot melt equipment heats EPS through heating chambers to temperatures of approximately 200-210 degrees Celsius, causing it to melt and compress.
Step Four: Cooling and Solidification
After melting or compaction, extruded EPS material requires cooling and solidification through cooling systems. For thermally processed materials, molten foam is extruded into thin strips, then cooled through water tanks. Cooling systems ensure materials maintain stable shape and consistency, preparing them for subsequent cutting or storage.
Step Five: Cutting and Pelletizing
When using complete pelletizing systems, cooled EPS strips are fed into cutting machines for pellet formation. Cutters typically feature 19 blades, enabling material cutting into uniform pellets. Cut pellets pass through vibration screens for screening, with unqualified pellets automatically rejected to ensure final product quality.
Step Six: Storage and Reuse
Final products are stored in silos as dense blocks or pellets, conveniently transported to manufacturers. These recycled materials can be used to produce new building insulation materials, picture frames, plastic products, and other items, achieving resource circulation. Recycled EPS materials enjoy high market acceptance, creating additional revenue streams for enterprises.
Core Components of EPS Recycling Machines
Complete EPS recycling systems typically include the following key components:
- Feeding System
- Melting Chamber or Compaction Chamber
- Screw Extrusion System
Sustav hranjenja - Cooling Device - Cutting System - Control System Critical Operational Considerations - Temperature Control is the core of hot melt equipment operation. The first extruder temperature is typically set to 210 degrees Celsius, the second extruder to 197 degrees, and the die head temperature to 200 degrees. Operators must observe material melting degree, raising temperature if material is too hard and lowering it if too thin. - Maintenance is crucial for extending equipment lifespan. After daily production, residual materials in screws must completely flow out to avoid cooling and solidification. If materials are not completely melted during second-day startup, screw wear increases, potentially damaging equipment components in severe cases. Blowtorches can be used to accelerate temperature rise, rapidly melting solidified materials. Regular addition of lubricating oil and component cleaning are also important measures for maintaining equipment in good condition. Safety Operating Procedures require operators to ensure waste contains no hard impurities such as metals or stones, which can damage crushers, screws, and cutters. Equipment is equipped with hydraulic stations, electrical control panels, and movable plates as safety devices. All systems must be carefully checked for normal operation before starting. Economic and Environmental Benefits of EPS Recycling Kontrolni sustav manifest in multiple aspects. By reducing EPS volume by up to 90%, enterprises can substantially lower transportation and storage costs. Recycled foam materials can be sold as raw materials or internally reused, creating additional revenue. Meanwhile, recycling processing is more economical than landfill disposal, reducing waste handling expenses.
