PET bottle crushing washing drying machine

PET bottle crushing washing drying machine

PET bottle crushing washing drying machine is equipment for recycling waste PET bottles, which can crush, wash, and dry PET bottles to obtain clean and dry PET bottle flakes. Here is a detailed introduction:

Working principle of PET bottle crushing washing drying machine

Crushing: The PET bottles are sent to the crusher through the conveyor. The crusher uses high - speed rotating blades to break the PET bottles into small flakes.

Washing: The crushed PET bottle flakes enter the washing unit. The washing methods include high - pressure water jet washing, friction washing, and floating washing. High - pressure water jets can wash away the dirt on the surface of the bottle flakes, and friction washing can remove stubborn attachments through high - speed friction. The floating washing utilizes the density difference to separate the bottle flakes from impurities such as PP caps and labels.

Drying: After washing, the PET bottle flakes are sent to the drying unit. The drying methods mainly include centrifugal dehydration and hot - air drying. Centrifugal dehydration removes most of the moisture through high - speed rotation, and hot - air drying further dries the bottle flakes with hot air to reach the required dryness.

The main equipment of the PET bottle recycling production line:
Conveyor, bag opener, stripper (dry stripper or stripper with water), sorting system (manual sorting can also be equipped with automatic sorting equipment), metal detection system, crushing (crushing) machine, rinsing Tank, thermal cleaning machine, friction cleaning equipment, downstream rinsing tank, dehydration machine, drying system, label separation system, and packaging equipment; through the above series of equipment, the label on the bottle surface can be effectively removed, the bottle cap and the glue can be removed. , Silt and other impurities, and finally get clean flakes.

Structural composition of PET bottle crushing washing drying machine：

Crushing part: It mainly includes a crusher with a motor, a blade, and a feeding hopper. The motor drives the blade to rotate at high speed to crush the PET bottles.

Washing part: Usually includes a 漂洗水槽 (floating washing tank), a hot washing tank, a friction washer, etc. The floating washing tank is used for the preliminary separation of bottle flakes and impurities, the hot washing tank can remove glue and other stubborn dirt with hot water, and the friction washer can enhance the cleaning effect through friction.

Drying part: Commonly used drying equipment includes a centrifugal dehydrator and a hot - air dryer. The centrifugal dehydrator is equipped with a rotating drum, and the hot - air dryer is equipped with a heating device and a fan to blow hot air for drying.

Conveyor part: Composed of belt conveyors, screw conveyors, etc., it is used to transport PET bottles and bottle flakes between various processes to ensure the continuous operation of the production line.

Features of PET bottle crushing washing drying machine：

High - efficiency recycling: It can process a large amount of waste PET bottles in a short time and convert them into reusable bottle flakes.

Good cleaning effect: Through multiple - stage washing processes, it can effectively remove dirt, labels, caps, and other impurities on the surface of PET bottles to ensure the cleanliness of bottle flakes.

Energy - saving and environmental protection: Some equipment adopts energy - saving designs, and at the same time, it can realize the recycling of waste PET bottles, which is in line with the requirements of environmental protection.

Application scope of PET bottle crushing washing drying machine：

It is widely used for the recycling and processing of various waste PET bottles, such as mineral water bottles, cola bottles, beverage bottles, and pesticide bottles. The processed PET bottle flakes can be used to produce PET polyester, short - fiber, long - fiber, sheets, and other products.
