Yes, PET, PP, HDPE, and LDPE bottle flakes can absolutely be transported automatically to a silo or storage unit after being crushed. The system is known as a Pneumatic Conveying System.

Here is a breakdown of how it works and its benefits, which aligns perfectly with XINYI MACHINERY's offering:

How the Automatic Conveying System Works:

1. Crushing: The plastic bottles are fed into the crusher (or shredder) where they are broken down into small, uniform flakes.

2. Picking Up: An air blower (or a vacuum pump/fan) is connected to the discharge outlet of the crusher. This blower creates a powerful airflow (typically negative pressure/suction) through a pipeline.

3. Transporting: The plastic flakes are immediately picked up by this airflow and transported through sealed pipes from the crusher to the destination.

4. Separation and Storage: The pipeline leads into the silo or storage bin. Inside the silo, a filter (like a cyclone separator or a bag filter) allows the air to escape while the heavier plastic flakes fall down due to gravity and collect at the bottom of the silo.

Key Benefits of This Automated System:

· Labor Savings: Eliminates the need for manual shoveling, carrying, or using forklifts to move flakes, significantly reducing labor costs.

· Hygiene and Cleanliness: The system is enclosed, preventing dust and flakes from contaminating the workshop and ensuring a cleaner production environment.

· Efficiency and Continuous Operation: Allows for non-stop operation of the crushing line, as the flakes are removed automatically without interrupting the crusher.

· Space Optimization: The silo can be placed in a location that optimizes factory layout, and the pipes can be routed around obstacles.

· Material Quality: Reduces the risk of contamination that can occur during manual handling.

The Role of Equipment Manufacturers like XINYI MACHINERY:

A manufacturer like XINYI MACHINERY provides integrated solutions. XINYI MACHINERY don't just sell a crusher; XINYI MACHINERY can supply a complete system that includes:

· The core Crusher or Shredder.

· The Air Blower (vacuum or pressure system) with the correct power and airflow for the material and distance.

· The Silo / Storage Bin with an appropriate separation and filtering system.

· The interconnecting Pipeline and fittings.

In summary, using an air blower and a silo is the most common and effective method to automatically transport PET, PP, HDPE, and LDPE flakes after crushing, and it is a standard offering from professional plastic recycling machinery manufacturers.
