Recycling of polyethylene film for recycling. Polyethylene processing: equipment, technology A fully equipped line contains

Pollution problem environment waste becomes more and more problematic every year. Polyethylene is used everywhere. It is used for packaging products, producing pipes, machine parts and building materials. The long process of decomposition of the material threatens the harmony on the planet. Therefore, it is so important to understand what technologies exist for recycling polyethylene.

Importance of Elimination

Modern material is not afraid of water, acids of various origins, alkali and solutions of chemical salts. For the production of products, such resistance to external influences only helps, but it may threaten an environmental disaster.

Polyethylene waste is very dangerous. The substance is subject to thermal aging and slow decomposition under the influence of heat, sun and air. During this period, the material begins to release caustic substances that pollute wastewater and soil.

The decomposition lasts at least a century. Looking at this, environmentalists are sounding the alarm and trying to prevent a catastrophe.

It is impossible to significantly reduce the production of polyethylene products, but organizing the production process correctly is quite possible. To do this, it is necessary to create and improve methods for recycling polyethylene. The modernization process will give waste another life: it can be used as secondary raw materials.

Every year the number of organizations whose activities are related to the processing of hazardous waste is growing. This is due not only to the deterioration of the atmosphere. Recycling of harmful substances is considered a profitable business sector.

From used film and polyethylene you can create raw materials for:

1. Garbage bins.
2. Panels.
3. Household and industrial containers.

Despite the emergence of new recycling technologies, the production of goods from such raw materials has limitations.

The recycling of polyethylene waste itself is not difficult. Materials used in Everyday life, remain unchanged, since their use does not last long, and their service life for industrial use is much longer.

Impact on polyethylene in such conditions has a large scale. The sun's rays and constant temperature changes have a strong impact on the material. Dust that appears during operation cannot be removed. Recycled raw materials are not famous high quality, therefore it is not suitable for production in any field.

Subtleties of waste recycling

The types of products that can be made from recycled products have some limitations. The first phase has minimal effects on the important properties of new products, but each new cycle reduces them. Raw materials become suitable only for the manufacture of products whose mechanical characteristics are not so important for comfortable use.

Stages of classical polyethylene waste recycling:

Selection of equipment for the process

Creating raw materials for reuse from polyethylene is impossible without professional equipment. It is similar to plastic recycling machines.

The fully equipped line includes:

• Washing machine.
• Unit for crushing material.
• Centrifuge.
• Drying unit.
• Extruder.
• Agglomerator.
• Granulator.

It is also recommended to use a conveyor or pneumatic conveyor. They automate production, simplifying the waste feeding process. The agglomerator is the main device. It is here that the main process of film processing takes place. Under the influence high temperatures waste is converted into secondary raw materials called agglomerate. On the machine it becomes a finished product. For high recycling productivity, it is necessary to use agglomerators with high power. The price of these machines is much higher than regular ones, but the quality is comparatively better.

Polyethylene granulation is the next step after grinding and agglomeration. A pellet making machine is most often included in the production line, but its use is not a requirement.

But it is worth remembering that the sale of polyethylene granules is in demand. Their production can significantly increase profits and expand the customer base.

The technology for processing polyethylene film is improving every year. Cross-linked polyethylene is especially popular. This is a material that has improved properties. It has a wide scope of application. It is used to produce gloves, packaging film for products, heat-shrinkable tubes and polymer pipes. The stitched material is very rigid. Its operating temperature after processing can reach up to 120 degrees.

Obtaining agglomerate is the first production step in processing recycled plastic. Of course, to reduce large waste to a fraction acceptable for crushing in an agglomerator, preliminary crushing in industrial shredders or crushers is necessary. However, many enterprises are focusing on processing more accessible materials that do not require preliminary preparation.

Application of agglomerator

The agglomerator is the equipment of the first processing line plastic waste- stretch films, polypropylene, polystyrene, as well as low and low polyethylene high pressure and other types of polymers. The machine allows you to obtain an output product - an agglomerate - that is ready for further use or sale.
In addition to grinding raw materials, technological process allows additional drying of the material during the agglomeration process, however, the use of raw material reduces the productivity of the equipment. For this reason, it is recommended to use more efficient solutions for pre-washing.

Production of plastic agglomerate

The crushing of plastic in the agglomerator occurs due to the rapid rotation of movable knives. The shape and sharpening angle of knives can have a significant impact on the efficiency of working with various types waste. Because due to the friction of the crushed mass against the agglomerator body and the surface of the moving and stationary knives, the material is heated. A homogeneous heated mass cools sharply and, under the action of chopping knives, rolls into separate uneven balls various shapes, ranging in size from 0.5 to 5 mm depending on the feedstock. The resulting agglomerate can be used directly in injection molding machines or sent for granulation.

FILM RECYCLING IS PROFITABLE, PROMISING AND ENVIRONMENTALLY FRIENDLY!

The demand for processing polymer waste and at the same time producing new film materials is increasing from year to year. In addition to large factories, quite a lot of small manufacturing enterprises have recently opened in need of timely processing of used film. Huge volumes of film waste are also provided by shopping centers and stores of various profiles. The segment of potential consumers of the product obtained after processing (agglomerate) are companies that are in one way or another engaged in the production of films, as well as various products from non-food polymers. If you build your business on processing film waste, you will be able to work with both their suppliers and consumers of the agglomerate.

What is needed?

Processing does not require large areas and a whole staff of specialists. You can organize this work on your own, even if you have limited space. For these purposes, you will need to purchase a rotary agglomerator - special equipment for processing HDPE (polyethylene). low pressure, LDPE (high-density polyethylene) and stretch films. Using an agglomerator, you can also process polypropylene bags and big bags, but it all depends on the modification of the equipment.

How does an agglomerator work?

This equipment is used for grinding, washing, drying and agglomerating waste. Depending on the configuration, agglomerators are single- or double-rotor. Structurally, the agglomerator consists of a frame, an electric motor, a housing and a unit with knives attached to the shaft. The operating principle is simple: film waste is loaded into the working chamber, after which it is crushed and sintered. Adding “shock” water allows this mass to cool and polymerize. The output is granules irregular shape(pellets) measuring 3-10 mm.

Depending on the performance of the equipment, it may be necessary to pre-shred the film with crushers before filling it into the chamber. This will allow the use of low-capacity agglomerators for processing. Powerful agglomerators (more than 200-250 kg/hour), as a rule, produce large granules. However, the smaller the agglomerate size, the more suitable it is for use as a secondary raw material.

Where is the agglomerate used?

The resulting product can be used both as a secondary raw material for the production of films and for granulation, which also expands opportunities for business development. Film materials are in great demand today in almost all areas, so there will be no shortage of customers for agglomerate.

How much can you earn?

The cost of a budget-class industrial agglomerator ranges from 195,000-370,000 rubles. According to average calculations, the difference in price between film and agglomerate is from 10,000 rubles/t. Let's take as a basis that the profit per kilogram of raw materials is 5 rubles (this figure can be twice as much).

In an hour, a two-rotor agglomerator easily processes 200 kg of raw materials - a total of 1000 rubles. (200 kg x 5 rubles = 1000 rubles/hour). For an 8-hour shift it turns out to be 8,000 rubles. (1000 x 8).

If you work in two shifts, then this is already 16,000 rubles/day (1000 x 16).

For a month (22 working days) the profit will be 352,000 rubles. (16000 x 22).

Thus, in one month you can completely recoup the purchase of equipment and start making a profit the next month.

Spin off

• To organize work and place equipment, large areas are not required, therefore, this is a significant saving on rental costs. You can organize film processing in a warehouse or other suitable premises.
• One or two specialists can work with the agglomerator (depending on the scale of processing and the model of equipment). No special qualifications or special knowledge are required either. Therefore, the costs for wages employees will also be insignificant.
• When purchasing a high-performance, but at the same time energy-efficient agglomerator, energy costs are also reduced.
• Other operating costs, such as maintenance and replacement of parts, also depend on the quality and reliability of the equipment. Based on this, it is advisable to buy agglomerators from leading manufacturers. Even if the payback period in this case increases, this will be compensated by the absence of regular repair costs.

Bottom line.

Organizing the processing of film materials to produce agglomerate is a stable business that does not depend on seasonality or fluctuations in demand. The demand for processing film and purchasing agglomerate for its production will only grow. Purchasing an agglomerator is a win-win investment with a quick payback and the possibility of further expansion of activities. Subsequently, it will be possible to purchase equipment of a different modification for processing a wider range of materials.

Agglomerator for film recycling is a knife or disk machine for mechanical and processing of thin-walled elastic polymer waste, which can have different shapes.

What is polymer agglomeration?

Film recycling by polymer agglomeration- a process in which thin-walled polymer raw materials are crushed, melted and naturally sintered.

Materials that can be processed using an agglomerator

• stretch film;
• LDPE film;
• polygon film;
• HDPE film;
• PP film;
• PP bag;
• other film waste.

Agglomerator design

Agglomerator for polyethylene is a tank with an elliptical or round, which is equipped with movable and stationary knives, a water supply system and a discharge system for finished raw materials. There are knife agglomerators (with a rotor equipped with knives) and disk agglomerators (with a movable disk - with knives on the bottom). The price of such processing machines is determined by their type, the presence of additional functions and productivity.

Working principle of the agglomerator

P Film processing using an agglomerator is carried out according to the following principle: polymer waste enters the processing zone, is crushed and heated. After this, the molten raw material is cooled with water, while the polymer particles are compressed and take the form of granules. After drying the equipment, the finished raw materials are removed to the storage hopper and the cycle resumes.

Polyethylene recycling is one of the few recycling technologies that provides a solution environmental problem waste, and can bring good profits.

The problem of polyethylene pollution on the planet is becoming more serious every year. The use of this material is so widespread that it is found in almost every area of ​​human life. Difficulties in disposal and long decomposition times threaten our planet. To solve the problem, processing technologies and reuse substances. This is a great way to get rid of the huge amount of garbage in landfills around large cities and build a profitable production on this basis. Implementation of this method in on a global scale- a chance to defeat an environmental disaster.

Relevance of polyethylene recycling

It is not easy to recycle this material - the structure and composition of polyethylene provide resistance to various chemical factors, which makes it so popular. In terms of use, these qualities are exactly what you need. However, these same properties lead to the impact of waste on the environment.

Polyethylene takes about 300 years to decompose. Another dangerous factor is that when decomposed, polyethylene objects can release hazardous substances into the biosphere. chemical elements that pollute the air, soil, and groundwater. These actions add up to environmental and public health impacts.

If this material has such amazing properties and is stored for several hundred years, the question arises, why not take advantage of these qualities of the waste. Modern technology allows for the recycling of polyethylene waste at such a level that the material becomes again suitable for use. This is both a way to save on new materials and a solution to the problem of environmental pollution.

For the smooth and constant functioning of the processing system, it is necessary to collect raw materials and have the necessary equipment. Subsequent processing will provide waste new life as everyday household items.

The number of enterprises involved in processing polyethylene waste naturally increases every year - this is facilitated by the relevance and demand for this service. The cheapness of the starting material and the wide possibilities for producing goods for which the demand does not fall are the key advantages of such a business.

Important point. The use of products made from recycled polyethylene must be stated on the product packaging, while the quality of the recycled product is inferior to virgin polyethylene. This fact should be taken into account.

How does the raw material processing process take place?

Waste is processed in several successive steps:

• collection of raw materials;
• sorting;
• primary processing;
• grinding;
• centrifuge processing;
• effect of temperature;
• use of material for the production of products.

Collecting raw materials and sorting them is the beginning of the process. At this stage, waste is divided into categories that correspond to the type of raw material. Sorting can be done manually or using mechanized devices.

Sorted waste must be cleaned of contaminants and parts made of foreign material. Raw materials are cleaned in special washing machines. Some collectors of raw materials themselves carry out this procedure, increasing the price of it.

Grinding of purified and prepared raw materials is carried out in special machines using crushing. The next processing step is centrifugation. This removes moisture and impurities from the material. After grinding, heat treatment of the material follows.

The raw materials are ready for recycling and the production of items from them.

Necessary equipment for polyethylene processing

For a complete and high-quality recycling process, the following equipment is used:

• washing machine;
• waste shredding machine;
• centrifuge;
• heat treatment plant;
• agglomerator - to reduce the volume of raw materials;
• granulator;
• extruder - to form homogeneous raw materials using temperature.

Automation of the process is carried out using a conveyor - this speeds up the process and allows you to control it step by step.

Using an agglomerator is one of the ways to increase the efficiency and economy of processing. The output is a commercial product - an agglomerate.

See the video for the operating principle of the agglomerator for polyethylene processing:

Using an extruder makes it possible to obtain low-density polyethylene, which is resistant to physical and chemical factors.

Extruders are also used to process raw materials (agglomerate) into a homogeneous melt and give it a certain shape.
