Throughout life, we must deal with different polymers. They have been used for the past few decades for the manufacture of a wide variety of products, from plastic containers to parts for space construction. In just one year, about 180 million tons of plastic for various purposes are produced on the planet.
A significant part of them is occupied by polymers that do not decompose and are unable to dispose of themselves. All this cannot but affect the ecological situation and often leads to ecological disasters. But the processing of polymers is not such a technologically difficult task. Moreover, on their basis, you can make useful things. Recycled plastic is virtually indistinguishable from virgin polymer and has almost the same performance characteristics.
Types of crushers
The whole variety of plastic recycling devices can be represented in the form of several groups according to the purpose and design of the main working elements.
Depending on the device and application, plastic waste crushers are of the following types:
With a more thorough study of a plastic shredder, among their many options, plastic shredders can be distinguished, and designed to process certain types of polymer waste:
Scope of application
The main users of plastic shredders are:
As a result of the processing of defective products, as well as other types of industrial plastic waste, a continuous supply of recycled plastic is ensured, from which new goods with the necessary consumer properties can be made. The process of reusing defective products and recyclable materials allows manufacturing enterprises to save considerable amounts of money on the manufacture of plastic products. This reduces the cost of finished products.
Organizations involved in the processing of used plastic products cooperate directly with companies that are direct manufacturers of polymer products. Therefore, the sale of recycled plastics can bring a very significant profit to the enterprise.
The principle of operation of crushers for plastic
Secondary plastic raw materials, which are most often presented in the form of bottles and film fragments, have a heterogeneous composition, which requires the use of various processing methods in relation to it. After all, these wastes can have different strength characteristics, viscosity, and brittleness.
Even though it is not difficult to cut film waste, it is almost impossible to crush it using impact crushers. Particularly laborious in this regard is ABS plastic, which has high rates of thickness and strength, and can only be crushed by sawing or impact.
To select the most suitable recycling method for recycled plastic, it is necessary to consider its thickness. It is for this reason that each grinding apparatus must be designed in such a way as to process a certain type of secondary raw materials most efficiently and quickly.
- Summing up
Considering the huge number of polymer products used by mankind, it is not surprising that in recent years interest has grown in such devices as plastic shredders. The main purpose of this device is to recycle plastic waste, which can later be reused to make new things that, in terms of their performance, will practically not differ from the original ones.
