" Buy a crusher !" - you decided one day after reading a huge amount of literature about the benefits of such equipment for the production process and the environment. However, the acquisition of crushers is a rather complicated process. Therefore, any buyer should also know how to choose the right crusher for plastics and other polymer products.
The plastic crusher is primarily characterized by the brand, series and model. Depending on them, these devices are equipped with additional functionality and differ in a certain quality. However, the principle of operation is the same for all crushers used for plastics. Anyone who comes up with the idea of "buying a crusher" must first familiarize themselves with the essence of its work.
Basic principle of the plastic crusher
As a rule, such equipment is most often based on the rotary method, therefore the basis is still the system of functioning of the rotor units. It includes the following steps:
- Placing the raw material into the loading hopper, where special knives located on the rotor capture this material and cut it for the first time.
- Further crushing is done by quick blows of knives on the rotating rotor.
- A special sieve screen, which determines the size of the granules of the required secondary raw materials, is located directly under the chamber where the grinding process takes place. The crushing process will continue until the polymer materials reach the specified dimensions.
When choosing reliable crushing plants: what to look for
Try to base your choice on your own needs. If your enterprise needs to process thin plastic, PET bottles, then choose equipment with cascade cutters, for film it is enough to purchase crushers with V-shaped knives. Larger and harder materials require specialized knives. Of great importance here, as in any technique, is the engine power, which affects the rotational speed. The ideal option would be a copy with the ability to adjust it.
Pay attention to the shape of the screen holes. Square cells make the plant more efficient, round ones make the resulting granules more uniform.
Since the torches are at the heart of the Plastics Grinder , make sure they are made of high strength, wear resistant material. This will help you extend the life of the device.
With these simple rules, you will definitely buy a high quality grinder that will last you for years.
