Considerations When Purchasing a Low Speed Granulator
Granulation was not always an important aspect of the plastics size reduction process, but it is now a chance to supply consumers with regrind and recycled materials in goods.
But, choosing the best plastics low speed granulator for your needs might be difficult. When utilized in particular conditions or situations, the unsuitable low speed granulator might potentially be dangerous.
The optimum low speed granulator for your needs will be determined by its intended usage.
Plastic that is either too big or too small will not be adequately processed without the right size low speed granulator and components, resulting in excessive energy consumption, noise and increased wear and tear.
The size of the equipment is an important consideration when choosing a plastic low speed granulator for your intended usage. Consider the following while selecting the appropriate size low speed granulator:
The low speed granulator faces varying needs depending on the process, whether it is blow molding, injection molding, extrusion, or recycling.
Which sort of plastic is being processed? In a low speed granulator, various polymers may behave differently.
Manual, conveyor, roll feeding, robot, and other feeding methods are available.
Product: If bottles or sheets are being processed, the low speed granulator may need to be adjusted differently.
Dimensions: The size and thickness of the processed product will also be considered.
How much materials can be processed in an hour?
Size of the Screen: What size will the processed material be?
Plastic low speed granulators must be serviced on a frequent and thorough basis to ensure a high-quality product and to decrease dust in the material as well as in the facility’s air.
There are various reasons why low speed granulator maintenance is difficult and may not be performed as frequently as it should be.
It is possible that the equipment was not constructed with maintenance in mind.
Instruction manuals may be deficient or insufficient.
Appropriate maintenance might take longer, resulting in more downtime.
It’s just difficult to find reliable maintenance services.
Maintenance of the low speed granulator knives is a particularly difficult chore, but it is also one of the most necessary.
Excess dust and particles might occur when the knives are worn down or poorly spaced. When the machine has sharp blades, it may enhance energy efficiency and cut the material more effectively, reducing dust, tearing, and noise.
A plastic low speed granulator should include several safety switches, power-assisted tilt-back hoppers, rotor locking mechanisms, and easily accessible and removable screen cradles and screens.
Equipment operators should also have a clear sight route to check the equipment if the low speed granulator has to be cleaned between processing cycles.
Design of a Knife
In terms of knife design in a plastic low speed granulator, various elements must be considered, including the number of knives, how they are placed, tip angle, speed, and sharpness.
The general design of the blades can have an effect on the final granulate quality as well as the efficiency of the machine.
Knives are commonly installed on a fixed bed or directly on the revolving rotor.
The amount of distance between these pairs of blades is determined by the size and kind of plastic being processed.
A smaller area will boost productivity and give a cleaner cut for softer, more ductile materials.
The angle of the blades is also affected by the material being treated.
