What are the machines for plastic recycling？

There are many different types of machines to recycle plastic, like extruders, pelletizers, pyrolysis machine, all of which have different characteristics as follows：

Compared with extruders, pelletizers, pyrolysis machines offer a simpler and more efficient alternative for plastic recycling. DOING has designed three types of plastic recycling pyrolysis machine: batch type, semi-continuous type and fully-continuous type, recycling waste plastics into valuable fuels, carbon black and syngas. Below are some of the machines commonly involved in plastic recycling through pyrolysis:

1. Plastic Shredder

If you choose a semi-continuous type and fully continuous type pyrolysis machine, the first step requires using a plastic shredder to break down large plastic waste (such as bottles, bags, or containers) into uniform, smaller pieces or particles, which makes the material easier to handle in subsequent stages.

If you choose batch type plastic pyrolysis machine, there is no need to break down the plastic, just throw the plastic directly into the pyrolysis reactor.

2. Pyrolysis Reactor

Heats the plastic in an oxygen-free environment. Inside the reactor, temperatures range between 350°C and 500°C depending on the plastic type, causing the material to break down into simpler hydrocarbons without burning. This produces gaseous, liquid, and solid byproducts.

3. Condenser System

Following pyrolysis, the resulting oil gas then flows into a condenser system, where it is cooled and liquefied into diesel, which uses multi-stage cooling and has an oil and gas recovery rate of up to 99%.

4. Distillation Machine

If you want to obtain a better quality fuel, it can be further refined, and the distillation machine processes the condensate into diesel for industrial use.

5. Tail Gas Treatment Device

The non-combustible and non-condensable gases are purified by the tail gas treatment device designed by DOING to meet the environmental emission standards and are discharged.

6. Carbon black Collection Machine

For the carbon black obtained after pyrolysis, the batch type plastic pyrolysis reactor can use the front slag discharge, the side slag discharge or the rear slag discharge method to discharge the carbon black after cooling. The semi-continuous type plastic pyrolysis reactor discharges the carbon black into a small reactor to achieve high-temperature slag discharge. The fully continuous type plastic pyrolysis reactor uses a multiple cooling system to directly discharge low-temperature carbon black.

More importantly, due to the particularity of some plastics, wax is easily deposited during the pyrolysis process. DOING plastic recycling pyrolysis machines provide a wax removal device. Whether you choose a batch type, semi-continuous type, or fully-continuous type, each machine is designed to maximize resource recovery while minimizing environmental impact and making profits.
