plastic flake recycling process

This PP PE flake recycling line mainly consists of a conveyor belt-crushing machine- rinsing tank - dewatering machine - conveyor - granulator - cooling tank - pelletizer and other components. It is also possible to configure exhaust gas purification devices, storage bins, bagging machines, and other related equipment according to customer needs. Through the above steps, the waste plastics are recycled for reprocessing. The entire production line from waste to finished products is easy to operate, with high efficiency, environmentally friendly, and energy-saving.

Belt conveyor

Belt Conveyor: Convey PP PE  material to the crusher machine.

Plastic-crusher

Crusher: Crush PP, PE material into small pieces

The waste plastic crusher is used for crushing the PP/PP material to small chios, it has the characteristics of low speed, low noise, and no slag material.

At the same time, wet pulverization not only enhance the water cleaning effect of plastic chips, but also reduce the friction heat due to the cooling effect of water, prolong the service life of the blade, low maintenance cost, long service life, therefore, so this type plastic crusher has received unanimous praise from customers

Rising tank

Rinsing tank: Rinse the crushed PP, PE

The rinsing tank is used for rinsing the broken material to precipitate impurities.

It is made of stainless steel or iron plate. There are many many toothed plates in the tank, it can force plastic chips to move forward and shift the material in the pool from this end to the other end of the pool.

Horizontal dewatering machine

Drying machine: Remove the water from PP, PE pieces.

Horizontal dewatering machine is specially used for cleaning and dewatering of waste plastic flakes and granules.

High degree of dehydration, dehydration rate of over 97%, low power consumption, high efficiency, high degree of automation, and greatly reduced labor intensity

Plastic pellet extruder

Plastic extruder: Heat and melt the PP, PE pieces, then extrude them with strip shape.

Waste plastic granulation extruder is a device for extruding, cooling, and dicing polyethylene (green film, lining bag, etc.) or polypropylene (old woven bag, packing bag, tying rope, etc.) to produce plastic granules. The granules produced are widely used and are ideal for PP PE plastic recycling.

This equipment is matched with the crushing and cleaning machine and the pelletizer. Broken and cleaned plastic can be directly put into extrusion granulation. Simple process, advanced technology, and suitable for different waste plastics.
Waster Plastic granulation extruder adopts automatic temperature control and electromagnetic heating, with less electricity, no pollution and high automation.

cooling tank

Cooling tank: cooling the soft strip plastic.

Cooling the soft strip plastic,make them hard then cutting them to pellet.

It is made of stainless steel, also, you can choose iron type, just choose it according to your demands.

pellet cutting machine

Pellet cutter: cutting the hard strip plastic to pellet.

This pellet cutting machine has superior performance and reasonable structure. The sealing performance of the whole machine is better, e less leakage ,and It is convenient to adjust the cutting distance.

The rotary cutter is made by hard alloy hob, its wear resistance is extremely high, the whole machine without gear design effectively reduces the machine noise with the belt rotation. and the independent electrical box is Convenient, safe, and beautiful. Cold-drawn pelletizing for various high-yield, high-strength engineering plastics.

storage bin

Storage bin: The storage bin is made of stainless steel, and the stock bucket and the wind-feeding material are combined into one, occupying less land and saving labor.

It can be docked with various granulators for easy movement. The fan power is small, the feeding speed is fast, save cost. The storage bucket size is customized according to customer requirements, and the size is optional.

What is the difference between PE and PP plastic?

There is no doubt that modern society is very dependent on plastic products. From product packaging and common household items to automobiles and industrial facilities. In the field of plastics used for consumer goods, two types are far more popular than others: polypropylene (PP) and polyethylene (PE). Then, there is a question: what is the difference between PE and PP plastic?

  • Polypropylene (PP) is a polymer made from the monomer propylene. It is a thermoplastic that is second only to polyethylene in terms of the rate of global production. PP is an excellent packaging material. It has excellent moisture resistance and resistance to a wide range of acids and bases. It also has a good combination of flexibility, strength, impact resistance, and fatigue resistance. It is widely used in product packaging, fabrics, healthcare, and automotive applications.
  • Polyethylene (PE) is the most widely used plastic in industry and daily life. It is generally divided into two types: high-density polyethylene (HDPE) and low-density polyethylene (LDPE). PE has excellent resistance to acidity and alkalinity. Almost all the plastic bags and various translucent or opaque plastic bottles seen on the market are made by HDPE, such as detergents, shampoos, shower gels, edible oils, pesticides, etc. Cling film and plastic film are usually made of LDPE.

Working principle of plastic pelletizing machine

This plastic pellet making machine is developed through the introduction, digestion, and absorption of advanced concepts and technologies at home and abroad, combined with the needs of today's development and the characteristics of recycling of waste plastics. It can meet the environmental protection requirements for the recycling of waste plastics at home and abroad. Handle hard plastics such as discarded plastic baskets and barrels.

Methods for the plastic pelletizing machine does not discharge

In the process of using the plastic granulator, the problem of non-discharge is prone to occur, there are some following suggestions:

1.The causes of the low lubricating oil pressure are listed as following. The pressure setting value of the pressure regulating valve of the lubricating oil system is too low, the oil pump is faulty or the oil suction pipe is blocked. The solution is to check and adjust the pressure regulating valve of the lubricating oil system and then check the oil.

2.The rotation speed of the main motor is not uniform, the rotation speed of the feeding motor is not uniform, and the feeding amount fluctuates. The treatment method is to check the main motor control system and bearings.

3.If there is no problem with the pelletizing machine, you can check is there any iron or orther things like a large piece of hard material has been introduced, and affect the normal operation of the machine.
