Recently, I have encountered many customers who inquired about the agglomerator, so today I write this article to introduce the agglomerator to everyone. I will discuss the definition, application, working principle, features, routine maintenance, and some precautions of the agglomerator. I hope it can be helpful to everyone.

1. Definition of plastic agglomerator

The agglomerator is a kind of recycling equipment, which is used for various soft plastic films, such as polyvinyl chloride, polypropylene, low-density polyethylene, high-density polyethylene, linear low-density polyethylene, etc., and bags, wires, belts, sheets, pipe waste and leftovers, then put into reproduction; it can also be used for the recycling and reproduction of degradable plastic film and corner material crushing and granulation; it can also crush and granulate chemical fiber materials (polyester, acrylic, polypropylene, etc.), and put into reproduction waste silk processing. Besides, it can also replace a mixer or dryer.

2. Application of plastic agglomerator

The agglomerator is mainly used for recycling and agglomeration of waste plastic products such as soft polyvinyl chloride, high-pressure polyethylene, low-pressure polyethylene, polypropylene. Also include other thermoplastics and foamed materials such as films, sheets, bags, silk, and nets. 

3. Working principle of plastic agglomerator

The agglomerators use the principle of frictional heat generation, which can directly crush various forms of thermoplastic films into pellets at one time. The main working principle is rapid pulverization, continuous stirring, friction heating, plasticization, cooling and shrinking molding with multiple tools; namely after the waste is put into the machine pot, the material is quickly cut into pieces by the shearing action of the high-speed rotating blade and the fixed blade. The chopped materials or pieces flow along the inner wall of the pot under the action of the centrifugal force of the rotary cutter disk, and at the same time, the materials are turned up and down by the action of the lower paddle, moving from the surrounding to the center of the pot. Due to the friction between the materials themselves and the friction with the pot wall and blades at high speeds, a large amount of frictional heat is generated, so that the temperature of the materials rises rapidly to a semi-plasticized state, and they adhere to each other into small pieces. Before the material is about to agglomerate, spray all the pre-prepared quantitative water into the material. When the cold water meets the hot material, it quickly vaporizes and takes away the surface heat of the material, so that the surface of the material is cooled rapidly to prevent agglomeration, and then passed through The crushing action between the rotary blade and the fixed blade causes it to be shredded into granules (irregular and irregular granules). In the shredding process, the appropriate pigments can be added for coloring as needed. The pellets produced by this machine can be directly supplied to extruders and injection molding machines to produce products. For products with strict requirements, they can also be pelletized by the extruder granulation before use.

4. Features of plastic agglomerator

After more than ten years of customer’s production practice, continuous innovation and optimization, this machine has successfully developed a cyclic pressure lubrication system, which greatly prolongs the service life of the bearing compared with ordinary yellow grease lubrication, thereby greatly reducing the maintenance rate of the equipment, and has gained a lot of favor of old customers. This technology is exclusive nationwide, absolutely value-added, and can stand the test of time.

5. Routine maintenance

In order to ensure the normal operation of the belt agglomerator, normal daily use and careful maintenance have a great impact on the service life of the equipment. It is necessary to formulate safe operation procedures and maintenance systems, and carry out regular repairs and replacement parts to prevent incorrect operation cause equipment and personal accidents. The safe operation regulations and reasonable maintenance system should be carefully formulated by the user according to the actual conditions on-site. The following precautions should be considered when formulating.

(1) Under normal use of the equipment, the agglomerator must not be used to complete tasks other than those specified in the design, and overload operation is not allowed.

(2) The passage to the emergency stop switch should be free of obstructions. Regularly check whether these switches are in good condition.

(3) Always pay attention to the condition of the transmission belt, pay attention to the tension in time; replace the failed V-belt in time.

(4) Clean up the materials stuck on the surface of the knife and the inner wall of the pot, and clean up in time.

6. Notes

The test run and operation of the machine should be carried out by personnel familiar with the process to prevent accidents. And strictly pay attention to the following precautions.

(1) Check whether there is any foreign matter in the pot before starting the machine, if there is, clean it immediately;

(2) Turn on the power supply, start the main motor, and check that the rotary knife is turned clockwise;

(3) Check whether the discharge door is working normally and whether the discharge door can be opened and closed as required.

(4) The craftsman must determine in advance the spraying temperature and the amount of spraying water for the materials to be agglomerated before feeding.

(5) The materials must be loosened before adding materials, and then gradually added, especially for strips and fibrous materials, which need to be added carefully to avoid material entanglement.

(6) When feeding, it should be noted that the short-term load of the motor should not exceed the rated power. When it exceeds, the feeding should be stopped for a while and the material should be loosened and added gradually.

 Finally, if this article still doesn’t solve your questions, welcome to contact me and we can discuss it together.
