Plastic recycling machinery: crushers, mills and complete lines

At Silmisa we manufacture plastic recycling machinery designed to optimize each phase of the recycling process for this material, guaranteeing maximum efficiency, material quality and profitability. Since our founding in 1987, we have established ourselves as a benchmark for plastic recycling companies.

Our equipment ranges from the most compact plastic recycling machine to complete industrial processing lines. Each of our machines can work with different polymers such as PET, HDPE, PP, PS, PVC, LDPE, etc., ensuring consistent results and high-quality polymer recycling ready for reuse in new products or production processes.

What plastics can you process?

Our machinery is designed to process most industrial plastics, both rigid and flexible. Each type of plastic requires a specific configuration of speed, screen, and cutting system, and our equipment can be adapted to each material to achieve maximum performance in the polymer recycling process.

PET (Polyethylene Terephthalate)

We reduce, wash and prepare the material for subsequent reuse in flakes or pellets, guaranteeing purity and performance in every cycle.

HDPE (High-density polyethylene)

Our machinery is designed to shred and homogenize HDPE while maintaining its structural quality.

PVC (Polyvinyl chloride)

Our equipment is designed for safe handling, preventing degradation and maximizing material recovery.

LDPE (Low-density polyethylene)

Our machinery facilitates the reduction and cleaning of this material, even in situations where it arrives highly contaminated.

PP (Polypropylene)

We have machinery for precise crushing and optimal classification for reintroduction into new processes.

PS (Polystyrene)

We adapt the equipment according to the density of the material, guaranteeing fluidity throughout the polymer recycling process.

Raffia

Our machines allow you to cut and prepare raffia without tangles or jams, ensuring a continuous level of productivity.

Plastic film

Our equipment recycles it without complications, allowing it to be washed, dried and prepared for pelletizing.

Thermal blanket

We offer stable and efficient material treatment for crushing and recycling.

Others

If you work with other types of plastic or mixtures, we design customized solutions. Our technical team analyzes your waste and develops the best treatment and recovery solution.

Machines specialized in recycling plastics

Recycling plastic requires a sequence of equipment working in a coordinated manner. From the initial size reduction to obtaining the clean, granulated material, each machine performs a specific function within the recycling line.

Pre-shredder - Shredder

The main function of these machines is to break down and condition materials before the main shredding process. They are primarily used for dirty, compacted, or mixed plastics.

Shredders

These machines are designed to reduce bulky parts and difficult materials such as film, raffia, jerrycans, pipes, or engineering plastics. Their robust construction allows for stable operation even during intensive shifts.

Granulators-mills

Mills and granulators offer homogeneous and precise grinding, ideal for processing industrial waste, production rejects, and post-consumer material. They are perfect for processing recycled plastics such as PP, PE, PET, and PS.

Laundry

Plastic washing systems ensure the removal of contaminants such as labels, dust, or product residue. They are ideal for treating polymers such as PET, HDPE, film, and raffia.

Centrifuge

Drying centrifuges allow the moisture content of washed plastic to be reduced to optimal levels for further processing.

Cyclone

This peripheral ensures efficient movement of granulated or crushed material, preventing blockages and losses. It is essential in lines requiring continuous flow between stages, such as mills and washing plants.

Overband

Overband separators allow the removal of ferrous metals from the plastic flow, thus protecting downstream machinery such as mills or granulators.

Conveyor belt

Industrial conveyor belts allow for a smooth movement of plastic material between the different stages of the recycling process.

Chain tape

The chain conveyor is ideal for the initial feeding of heavy or bulky material such as: boxes, technical parts or large sheets.

Recycling plants of plastic and processing lines

We manufacture complete plastic recycling plants configured to maximize efficiency at every stage of material treatment.

Each plant is configured according to the type of polymer, the level of contamination, the waste format, and the required final purity level. This allows plastic recycling companies, processing industries, and waste management companies to operate with complete reliability and achieve consistent performance over time.

Innovation and benefits of plastic recycling

Recycling plastic using specialized machinery reduces waste management costs, generates valuable secondary raw materials, and contributes to companies’ circular economy goals. Our equipment is designed to maximize process efficiency while minimizing energy consumption and downtime.

Higher performance per hour

Thanks to optimized cutting, washing and separation systems.

Reduction of operating costs

Through lower energy consumption and more efficient maintenance.

Higher purity recycled material

Ideal for reuse or sale with higher added value.

Safer and more automated processes

Reducing occupational risks and operational errors.

Adaptation to multiple polymers

Such as PET, HDPE, PP, PVC, film, raffia...

Long life

Throughout the machinery, thanks to reinforced components and proprietary technology.
