Shredding and Recycling Rigid Plastics

Rigid plastics are a type of plastic material that are produced through various thermoforming processes. These plastics are often used in private households and the industrial sector for products such as buckets, watering cans, plastic pallets, trash containers, and pipes.

Unfortunately, many rigid plastics are often mistakenly thrown away in the residual waste garbage can or bulky waste. When this happens, these plastics can no longer be recycled and are often incinerated to generate energy.

To combat this issue, it is important to recycle post-consumer and industrial rigid plastics. One effective way to do this is through shredding with machines like the Rumtoo shredder. By shredding rigid plastics into high-quality recyclate, we can create the foundation for all products made from recycled plastics, thereby promoting sustainable processing practices.

Overall, recycling rigid plastics is crucial for reducing waste and conserving natural resources. By properly recycling these materials, we can extend their lifecycle and create a more sustainable future for generations to come.

What are rigid plastics?

Rigid plastics are a type of plastic material that is stiff, strong, and retains its shape even when not in use. They are produced through various thermoforming processes and include products such as buckets, watering cans, flower pots, pasta strainers, garden furniture, laundry baskets, plastic pallets, trash containers, and pipes. Due to their durability and strength, these plastics are often used in private households and the industrial sector.

Rigid plastics differ from flexible plastics, which are soft and pliable, and are often used for products like plastic bags, packaging films, and shrink wraps. While both types of plastics can be recycled, rigid plastics are often more difficult to recycle due to their size and shape. However, with the use of advanced recycling technologies and machinery, recycling of rigid plastics is becoming more efficient and effective, and is an important step towards reducing waste and promoting sustainable processing practices.

What materials are rigid plastics made of?

Rigid plastics are made of various materials including:

PE (Polyethylene)
HDPE (High-density Polyethylene)
PP (Polypropylene)
PS (Polystyrene)
PET (Polyethylene terephthalate)
PA (Polyamide)
PC (Polycarbonate)
ABS (Acrylonitrile butadiene styrene copolymer)
PVC (Polyvinyl chloride)

Rigid plastics can be produced from thermoplastics using various processes. For example, toys and car parts are manufactured by injection molding, bottles and containers are produced by blow molding, and large hollow bodies such as industrial drums or water storage tanks are produced by rotational molding.

This document describes an effective Rigid Plastics Shredder Recycle Machine for processing large pieces of rigid plastics, such as plastic lumps, extruder purges, entire sheet rolls, and more.

Uvod

The Rigid Plastics Shredder Recycle Machine described here is an ideal solution for shredding rigid plastics due to its many impressive features.

One key feature is its continuous feeding mechanism, which allows for high shredding efficiency and uninterrupted shredding of materials. The machine also has a movable hopper that enables jam-free shredding of rigid plastics, ensuring smooth and efficient operation.

To further maximize productivity, the rotor is customized with a large rotating diameter, providing a greater shredding contact surface. This helps to increase the speed and effectiveness of the shredding process.

In addition, the transmission parts of the machine are connected by a coupling, reducing vibration and protecting the main shaft and reducer from damage caused by force. The machine also has stationary knives placed on the top and bottom of the main shaft, which effectively cut the rigid plastic material without warping the main shaft.

To ensure a safe and stable work environment, this Rigid Plastics Shredder Recycle Machine is equipped with a PLC self-programming electrical control system that allows for functions such as start, stop, forward rotation, and automatic overload protection. This fully automated system ensures the machine operates safely and efficiently.

Overall, these features make this plastic shredder machine a reliable and effective solution for shredding rigid plastics, allowing for increased productivity and reduced waste in the recycling process.

Uvod u sastav komponenti i princip rada jednoosnog šredera

Jednoosovinski drobilica je mehanička oprema koja se uglavnom koristi za drobljenje, obradu i recikliranje otpadnih materijala. Njene glavne komponente uključuju sljedeće dijelove:

Vratilo: Osovina je glavna komponenta drobilice s jednom osovinom, koja pokreće noževe za drobljenje materijala. Osovina je obično izrađena od čelika visoke čvrstoće i može izdržati radna okruženja s velikim opterećenjem.
Oštrice: Oštrice su važni dijelovi osovine koji se koriste za rezanje, kidanje, rezanje i mljevenje materijala. Oštrice su obično izrađene od legiranog čelika visoke tvrdoće i otpornosti na habanje kako bi se osigurao dobar učinak drobljenja i dugi vijek trajanja.
Lijevak za hranjenje: Lijevak za punjenje važan je dio jednoosovinskog usitnjivača koji se koristi za punjenje otpadnog materijala u stroj. Veličina i oblik lijevka za punjenje obično se projektiraju i optimiziraju prema karakteristikama materijala i zahtjevima obrade.
Izlaz za pražnjenje: Ispustni otvor je važan dio jednoosnog usitnjivača koji se koristi za ispuštanje usitnjenih čestica iz stroja. Dizajn ispustnog otvora obično se temelji na karakteristikama materijala i zahtjevima obrade.
Pogonski sustav: Pogonski sustav važan je dio usitnjivača s jednim vratilom, koji se koristi za prijenos snage elektromotora na osovinu i noževe. Pogonski sustav obično se sastoji od motora, reduktora, spojke i drugih komponenti.

Princip rada jednoosovnog usitnjivača je da otpadni materijali ulaze u stroj kroz lijevak za punjenje, noževi ih režu na male komadiće i kontinuirano se guraju naprijed dok se ne usitne na male čestice i ne ispuste kroz otvor za ispuštanje. Tijekom cijelog procesa drobljenja, velika brzina rotacije noževa uzrokuje različite sile poput trenja, smicanja i kidanja materijala, čime se učinkovito drobljenje i obrada otpadnih materijala.

Jednoosovinski u odnosu na dvoosovinski drobilice plastike

Jednoosovinske drobilice i drobilice s dvostrukom osovinom Obje se koriste za usitnjavanje plastičnih materijala. Međutim, drobilice s jednom osovinom dizajnirane su za obradu mekših i manje gustih materijala, dok su drobilice s dvije osovine prikladnije za tvrđe i gušće materijale. Drobilice s jednom osovinom također su općenito isplativije i zahtijevaju manje održavanja u usporedbi s drobilicama s dvije osovine. Međutim, drobilice s dvije osovine obično nude veću propusnost i proizvode ujednačeniji izlaz. U konačnici, izbor između drobilica s jednom i dvije osovine ovisi o specifičnim potrebama industrije i materijalima koji se obrađuju.
