Frequently Asked Questions
1. Can the MJ-2 machine be used for both waste plastic (PE, PP) and waste tyres?
Our pyrolysis plant for sale is designed to process both waste tires and plastics, but we will suggest not to mix in one batch, better separately.
2. How much time is required to heat the reactor to the optimal operating temperature? How long does the cooling process take before obtaining the final pyrolysis oil?
MJ-2 process for waste Plastic can be expected to be finished within 20 hours, highest temperature in the reactor around 420 ℃,
Feeding 1 ton : 20 mins
Pyrolysis Period: Around 4-5 hours
Reactor cooling down: 4 hours
ØCarbon discharging : 1 hours
Reloading 1 ton: 20 mins
Pyrolysis Period: Around 4-5 hours
Reactor cooling down: 4 hours
Carbon discharging : 1 hours
3. What is the expected purity of the oil produced by the MJ-2, and how much oil can be obtained from processing 1000kgs of PP or PE?
PE(Thin film, bottle, electrical insulating materials, hand bag, water pipe, oil drum , staple goods etc.) oil yield is about 70-80% for pure material.you will get 700-800 kg fuel oil.
PP(Thin film, rope, table ware, furniture, woven bag, bottle cap, car bumpers etc.) of pure oil yield is about 80% ,you will get about 800 kg fuel oil
4. Can we use the pyrolysis plant to proces MSW ?
Yes, from the MSW, pyrolysis machine mainly recovers fuel oil from waste plastic and waste rubber, before loading, we will suggest to do the pre-sorting to remove the inert materials at least , like metal, glass, stone, etc, to make sure the performance of the machine.
5. How can we use the distilled diesel from waste tires or plastics?
1. Can be used for heating.
2. Can be used in the low speed and heavy duty engines, like boat, diesel generator.
6.What can we do with the heavy oil from distillation machine?
1. Can be sold as asphalt, if there is a market at your local.
2. Can be put back into the pyrolysis machine and refine it again.
7. How can we use the carbon black from pyrolysis?
1. Can be pressed to be briquettes and used as fuel.
2. Can be further reprocessed to be higher quality, and used as fortifier and filler of plastic and rubber industry or as color master batch for producing some rubber products.
8. Can we process the mining tires in the pyrolysis plant?
Yes, but Mining tires generally have large dimension, for further discussion, please let us know what is the maximum diameter of the tires you are going to process, if larger than 1200mm, we will suggest to cut it firstly.
9. Do we need to wash the materials before loading into the pyrolysis machine?
The machine can accept dirty materials, so, there is no need for washing . But washing process will absolutely improve the quality of the oil.
10. How should we do the maintenance to the machine?
Take the batch plant for example, we suggest to stop the machine once a week for regular checking mainly for the wearing parts and lubricant, for each month, stop for one day for maintenance , mainly do the cleaning jobs.
For the continuous machine, when processing waste tires, once a month, we peocessing waste plastics, suggest to be twice a month.
11. What are the pyrolysis system guarantees?
All the plants from Mingjie has a 12 months guarantee since the act of acceptance is signed, during the warranty period, all the problems cause by quality will be resolved by Mingjie at its own cost, which will be indicated in the contract,
