Types of Plastic Bottle Recycling Machines

The plastic bottle recycling machine helps reduce plastic waste by reusing it, resulting in a more sustainable and circular economy for plastics.

The different types of recycling machines are as follows:

• Plastic Shredder:

  The primary step in most recycling processes is shredding or cutting the plastic into smaller pieces. A plastic shredder performs this task. It breaks down the plastic into more manageable pieces that are easier to recycle. The advantages of a plastic shredder are more manageable pieces, a streamlined recycling process, and automated feeding systems. Plastic shredders have multiple blade configurations and sizes, enabling them to shred different types of plastics.

• Granulator:

  Once the plastic has been shredded, it is then ground into even smaller pieces called plastic granules. Granulators perform this task by grinding the plastic into granules that can be used as raw material for new products. The advantages of a granulator are increased versatility, consistent product output, energy efficiency, and space-saving design. Plastic granulators can be centralized in the manufacturing facility rather than placed next to every production line.

• Plastic Extruder:

  The plastic granules produced by the granulator are then fed into an extruder. A plastic extruder machine melts the plastic and forms it into new products. After heating, the melted plastic is pushed through a mold to form new items. The advantages of a plastic extruder include high production rates, greater material utilization, automated controls, and lower operation costs. Depending on the type of product, different molds are used, such as for film, sheets, pipes, etc.

• Separator:

  Separators are used when different types of plastics need to be separated. It can use manual or automated systems to segregate the plastics based on shape, size, weight, and material. The advantage of a separator plastic recycling machine is the more pure product output, faster, and more efficient separation. Advanced automated separators use artificial intelligence and image recognition to sort better.

Specification & maintenance of plastic bottle recycling machines

The specification of plastic bottle recycling machines varies depending on the manufacturer's model. Here are some of the key plastic bottle recycling machine specifications to help business buyers narrow down their options.

• Production Capacity

  The production capacity of plastic bottle recycling machines often comes in tons per hour (TPH). Small-scale shredders, for instance, can handle 20 to 50 kg per hour of plastic bottles. On the other hand, larger industrial machine models can have a capacity of 500 kg to 1 ton per hour.

• Power Requirements

  Plastic bottle recycling machines have different power requirements depending on their size and capacity. For example, small-scale plastic bottle crushers use around 1 to 5 kW. Larger industrial crushing machines have power requirements of up to 100 kW or more.

• Machine Dimensions

  The dimensions of the recycling machine will vary according to its type. For instance, a shredder machine can measure around 2,200 mm (length) x 1,500 mm (width) x 1,400 mm (height).

• Material Compatibility

  Some recycling machines are manufactured to handle specific materials. For example, plastic recycling machines will only process plastics with particular resin codes — such as bottles made from PET (Polyethylene Terephthalate) plastic.

• Separating Mechanisms

  Some advanced plastic bottle recycling machines have automated separation mechanisms, like optical sorters, to discern and separate different plastic materials. Such specifications are crucial in large-scale recycling setups.

Proper maintenance of plastic bottle recycling machines increases their lifespan and ensures efficiency. Here are some essential tips on machine care.

• Routine Inspection

  Establish a weekly routine checklist and model maintenance schedule. Use it to inspect critical machine components, such as bearings, belts, and blades.

• Lubrication

  Remember to grease moving parts of the recycling machine. These include chains, bearings, and drives. Doing this reduces wear and tear and ensures smooth operation.

• Cleaning

  Regularly remove any leftover plastic debris after recycling. Do a thorough cleaning periodically to prevent the build-up of dirt, contaminants, and dust. This practice helps maintain product purity.

• Calibration

  Check and fine-tune the settings of the plastic bottle recycling machine occasionally. This procedure helps ensure that it reprocesses material at the desired size efficiently.

• System Updates

  When necessary, consider upgrading the machine's systems. These may include software and automatic sorting mechanisms. Such updates enhance productivity and simplify operation.

Scenarios of plastic bottle recycling machines

• Municipal recycling facilities

  Municipal recycling facilities are one of the main application scenarios for plastic bottle recycling machines. They usually collect a large number of waste plastic bottles from the entire city every day and have built the whole set of machines to deal with them. Given the volume and complexity of the bottles, there are usually more important and advanced machines featured in the recycling facilities to crush, wash, sort, dry, and granulate the bottles of different materials. It is also an automated assembly line, which means there is plentiful output, so it is suitable for municipalities to invest in such machines.

• Small plastic recycling plants

  Small plastic recycling plants also provide a suitable scenario for the bottle recycling machine. Compared to the municipal recycling facilities, the scale of the plants is smaller, but they can process local plastic bottles. The operators must think about how to run the business to make it economically viable, so the input capacity of the recycling machines may not be as big as the machines in the municipal facilities. Yet, the combination of the machines here is still useful, and it's probably more flexible. It may include mobile machines, which can be temporarily set up in flea markets or street vendors to deal with plastic bottle waste with a lower volume.

• Factories that produce recycled plastic products

  Some factories specialize in producing recycled plastic products and need plastic bottle recycling machines to obtain raw materials. They may focus on specific types of plastic products, such as T-shirts, sweaters, and other textiles or construction materials like insulation boards. Such factories may have more advanced machines that can not only recycle plastic bottles but also produce end products, such as plastic granules. They may feature injection machines that can mold the granules into new plastic products.

• West to East recycling model

  Recently, a new recycling model has been adopted in some areas, which is the west to east recycling model. In this model, all the plastic waste is collected in the western part of the region, where it is processed using recycling machines, and the end products are delivered to the eastern part of the region for sale. In this kind of model, the areas that have more plastic waste can set up recycling machines, and those that have the demand for the products can benefit from them.

How to choose plastic bottle recycling machines

When buying a plastic bottle recycling machine, the intended use and processing capacity are good starting points for consideration. An upright or horizontal model may suit the needs if space-saving is a priority, whilst an all-in-one metal, glass, and plastic bottle crusher may be essential for safeguarding against the risk of any glass bottle remnants within the end product.

For large-scale operations, such as industrial recycling, selecting a machine that can handle up to 2,200 kg/ph (kilograms per hour) of plastic bottle waste will help to attend to high-volume waste. Another area to focus on for large-scale operations is the storage capacity of the bales produced by the machine, which must be large enough to adequately store output before bales are sold further down the supply chain.

The removable parts are essential in a large-scale industrial recycling machine. It's critical that the blades and other parts exposed to shredding or crushing action are easy to remove and replace as necessary. In particular, when large-scale operations are targeted, ensuring that parts can quickly and easily be removed, replaced, and serviced is crucial.

For small-scale operations, ease of use becomes vitally important. Compact machines that can be used in the home, on a campus, or in a retail outlet should be easy to understand, use, and empty. They should also offer some vital security measures and low noise levels to ensure they can be used in a retail outlet.

Energy consumption is another area of focus, as operators will want to know how much electricity is used when shredding or crushing plastic bottles and how that may affect operating costs.

Emergency stop buttons or those required to stop the machine quickly should be accessible and clearly labeled, while operation manuals should be provided in various languages to ensure the machine can be adequately understood and operated.

A further consideration for some operators is whether a mobile or portable recycling machine is available that can travel to collection points instead of having to move waste material to the machine.
