In today’s society, the extensive use of plastic products has led to a large amount of plastic waste. In order to deal with these wastes effectively, various kinds of waste plastic crushing machines have come into being. In this article, we will focus on two common types of plastic crushers: plastic film shredder and PET bottle crusher. These two machines play an integral role in waste disposal, but they differ significantly in design and function.
Plastic film shredder
The plastic film shredder is a machine designed to process plastic film waste. It has some unique features that make it excel in processing film plastics. Here are the key features of the plastic film crusher.
Screen size
Plastic film crushers have larger screen sizes compared to PET bottle crushers. Typically, the screen size used for plastic films is about 90 mm. This relatively large screen size helps to process plastic film efficiently, preventing clogging and excessive wear.
Applicable materials
Plastic film crushers are mainly used to process plastic films such as plastic bags, packaging films and agricultural films. These materials usually have low density and soft characteristics and require a specially designed crusher to process them effectively.
Cutting method
The waste plastic crushing machine usually adopts the shearing method for cutting. This cutting method can effectively cut film plastic into small pieces without causing excessive dust and heat.
PET bottle crusher
PET bottle crusher, also known as universal plastic bottle shredder, is a multi-functional equipment suitable for processing all kinds of hard plastic wastes. The following are the main features of plastic bottle shredder.
Screen size
Compared with plastic film crusher, the screen size of PET bottle crusher is smaller, usually 24mm. This smaller screen size enables it to crush hard plastic waste into smaller pieces.
Applicable materials
The hard material crusher is suitable for processing hard plastic waste, such as plastic containers, pipes, injection moulded products and so on. These materials are usually harder and require more powerful crushing force to handle.
Cutting method
The PET bottle crusher usually adopts the blade-cutting method to cut. This type of cutting can effectively break hard plastics into small particles and use them for recycling or other disposal.
Importance of waste plastic crushing machine
Whether it is a plastic film crusher or a plastic bottle crusher, they play a key role in the processing and recycling of waste plastics. The ability of waste plastic crushing machines to break down waste plastics into a form that can be easily processed helps to reduce the volume of waste, increase recycling efficiency, and reduce reliance on natural resources.
