This is a project about milk jug crusher in New Zealand. The client in this project is a medium-sized recycling facility located in the Waikato region. The facility primarily processes post-consumer plastics, with a strong focus on polyethylene terephthalate (PET) containers used for milk and dairy products.
This is a project about milk jug crusher in New Zealand. In recent years, New Zealand has been actively enhancing its recycling infrastructure and waste management strategies. Among the innovative technologies adopted by recycling facilities, the milk jug crusher has become a vital solution for efficiently processing post-consumer plastics.
This case study examines the installation of a single milk jug crusher in a New Zealand recycling facility, detailing the project background, client requirements, equipment selection, and operational benefits.
The client in this project is a medium-sized recycling facility located in the Waikato region. The facility primarily processes post-consumer plastics, with a strong focus on polyethylene terephthalate (PET) containers used for milk and dairy products.
With the increasing return rates of milk jugs from households and local dairy suppliers, the facility faced challenges in efficiently handling irregularly shaped containers. Their previous shredding equipment often struggled with throughput and required frequent manual intervention, which slowed down operations and increased labor costs.
To address these challenges, the client opted to purchase a standalone milk jug crusher. Unlike a full production line upgrade, this approach allowed them to integrate a single robust machine that would handle preliminary crushing of milk jugs into approximately 3 cm pieces. This unit was designed to complement existing equipment, preparing the plastic for downstream washing and pelletizing processes.
Name:
milk jug crusher
Country:
New Zealand
Date:

Capacity:
Flexible
Model:
SSJ800
Main Motor Power:
22*2 kW
knife disc:
260mm
Knife disc material:
55crsi
The main materials for this project consisted of 1- to 2-liter PET milk jugs collected locally. These containers often had irregular shapes and varying thickness, which made conventional shredders inefficient. The client required a machine capable of consistent, high-efficiency processing of these materials.
After evaluating several models, the SSJ800 was selected. It features a 22*2 kW motor, a 260 mm alloy steel knife disc, and customizable knife disc teeth configuration to optimize crushing performance. This model aligns with the facility's throughput needs, processing several hundred kilograms of milk jugs per hour. The equipment reliably reduces the containers to 3 cm pieces, ensuring smooth operation in subsequent washing and pelletizing stages.
The milk jug crusher is equipped with a hexagonal shaft and removable knife discs, allowing for high crushing efficiency and easy maintenance. The knife discs are forged from alloy steel and precisely machined, offering excellent toughness, wear resistance, and the ability to be repaired or reused.
The machine’s heavy-duty shell, constructed with carbon dioxide welding and fully annealed, minimizes deformation and extends the service life. Sealed bearings prevent dust and moisture ingress, and automatic overload protection with reverse rotation safeguards the crusher from blockages, reducing downtime and maintenance costs.
The integration of the milk jug crusher into the facility brought several benefits:
With the SSJ800 milk jug crusher, the recycling facility in New Zealand was able to streamline its plastic processing workflow. The machine effectively transformed bulky, irregular milk jugs into manageable 3 cm pieces suitable for mechanical washing and subsequent extrusion into plastic pellets. These pellets are then sold to manufacturers who produce recycled plastic products, contributing to the circular economy and reducing environmental impact.
For this project, the milk jug crusher was shipped via sea freight to the Port of Auckland, one of New Zealand’s main commercial ports. From there, the machine was transported to the facility in Waikato, ensuring safe delivery and installation.
The milk jug crusher in New Zealand is a versatile piece of equipment suitable for processing a wide range of irregular plastic waste, not limited to milk jugs. It can handle containers of varying shapes and thicknesses, PET bottles, and other rigid plastic waste. Its hexagonal shaft, removable knife discs, high-capacity motor, and customizable blade configuration make it suitable for diverse industrial applications, including recycling plants, waste-to-energy facilities, and agricultural processing centers.
The client reported high satisfaction with the performance of the milk jug crusher machine. They highlighted the efficiency of reducing irregular plastic containers to uniform pieces and the ease of maintenance. According to the facility manager, "The SSJ800 has significantly improved our processing speed and reduced downtime. We can now handle larger volumes of milk jugs without the bottlenecks we used to face."
The deployment of the RICHI milk jug crusher in New Zealand demonstrates the machine’s effectiveness in modern recycling operations. Its robust design, high efficiency, and versatile capabilities make it a valuable investment for facilities aiming to improve plastic processing and recycling outcomes. For any recycling facility looking to enhance operational efficiency, the RICHI milk jug crusher offers a reliable and durable solution backed by expert support and engineering expertise.
This project showcases how a single, well-selected unit can transform a facility’s workflow, improve sustainability, and provide long-term operational benefits.
