Background Status

With the widespread application and rapid consumption of plastic products, the amount of plastic waste generated has increased sharply. These plastic wastes often contain high levels of moisture, which poses great difficulties for their disposal. Traditional dehydration methods, such as natural air drying and chemical dehydration, are not only inefficient, but also susceptible to limitations such as weather and environment, which cannot meet the needs of large-scale plastic waste treatment. Therefore, it is particularly important to find an efficient, stable, and environmentally friendly dehydration treatment solution.

Why choose mechanical dehydration technology

We choose mechanical dewatering technology because it can efficiently and quickly remove moisture from materials, shorten processing cycles, and is particularly suitable for large-scale plastic waste and sludge treatment. Mechanical dehydration equipment has a compact structure, easy operation, and is easy to automate, reducing labor costs and safety risks. At the same time, this technology reduces the use of chemical agents, has strong environmental friendliness, and conforms to the concept of sustainable development. In summary, mechanical dehydration, with its high efficiency, compactness, and environmental friendliness, has been widely used in multiple fields and has become the preferred solution for processing materials with high moisture content

Squeezing machine

Core mechanical equipment

Squeezing machines and squeezing granulators are the core dehydration equipment in the field of plastic waste treatment. Squeezing machine uses a spiral shaft or screw to rotate and strongly squeeze and shear plastic waste with high moisture content, granular or small pieces, quickly removing moisture, and the dewatering effect can be adjusted, making it easy to operate. The squeeze drying granulator further integrates dehydration and granulation on the basis of squeezing, extruding the dehydrated material into granular products for storage, transportation, and subsequent use. At the same time, the particle specifications can be adjusted according to market demand.

Process flow

Preliminary sorting: Mixed plastic waste is sorted by type, color, and pollution level through manual or automated sorting equipment.
Cleaning and purification: The sorted plastics are cleaned by high-pressure water guns, vibrating screens, and other equipment to remove impurities and ensure cleanliness.
Shredding refinement: The cleaned plastic is sent to the shredder and crushed into smaller pieces for subsequent processing.
Mechanical squeezing: The shredded plastic is strongly squeezed by a squeezing machine to remove moisture and reduce its moisture content.
Granulation molding: The extruded plastic fragments are heated and melted, extruded into a mold, cooled and shaped into plastic particles of uniform specifications.
Terminal processing:
High temperature cracking for oil production: Some plastic particles are converted into cracking oil and cracking gas in a high-temperature cracking furnace, which are used as chemical raw materials or energy.
Preparation of RDF fuel: Another portion of plastic particles are processed into high calorific value and stable combustion RDF fuel for power generation and heating.
