Even if granulation might not have been a vital element in the plastics reduction process some years ago, granulation is a chance to present clients with regrind and salvaged materials in products. Nonetheless, choosing the correct granulator for your needs can be tough. The incorrect granulator can even be perilous when utilized in certain situations or environments. Here are some elements to pay attention to in order to select the right granulator.
Intended use. The type of granulator that’ll fit your needs will depend on how you plan to use it. Without the right size granulator and components, plastic that’s too small or too big will not be rightly processed, which can result in increased wear on the knife, higher energy use, and additional noise and dust. To choose a granulator that suits your intended use, consider its size. To find the correct granulator, consider:
Application: There are various demands on the granulator based on the process; is it injection molding, recycling, extrusion, or blow molding?
Material: What kind of plastic do you process? Different plastics might react dissimilarly in a granulator.
Feeding method: They include roll feeding, robot, manual, conveyor, and more.
Product: The granulator might require to get configured differently if sheets or bottles are being processed.
Dimensions: The thickness and size of the product getting processed are crucial.
Capacity: How much material can get processed per hour?
Screen size: What dimension will the processed material be?
Plastic granulators require to get maintained thoroughly and often to ensure quality products and lower dust in the materials and in the air at the site. There are many reasons why granulator maintenance is taxing and might not be done as frequently as it should.
The equipment might not be made with maintenance in mind.
Instruction manuals might be inadequate or poor.
Proper maintenance can be time-consuming, increasing downtime.
It is simply tough to find the right maintenance services.
Maintenance of the granulator knives is a particularly tough task; however, it is also among the imperative tasks. When the knives are improperly spaced or worn down, it can lead to excess dust and fines. A machine with sharp knives can better energy efficiency and slice the material more effectively, assisting reduce dust, noise, and tearing of the material.
Knife design. There are numerous elements to pay attention to regarding knife design in a granulator, such as the number of knives, the way they’re arranged, sharpness, and the tip angle. The overall design of the granulator can affect the quality of the end granulates and the effectiveness of the tool. Knives are generally mounted directly on the rotating motor or on a stationary bed. The amount of space between these sets of knives will be determined by the size and kind of plastic getting processed. For shorter, more malleable materials, a small space is going to increase effectiveness and produce a cleaner cut. If you require granulates of alike size, a slower knife pace will lessen noise, lower wear on the knives and slicing chamber, and increase the production of uniform material.
