Leda plastic recycling  Plastic recycling washing line 
 
Again, cutting is a costly matter.
 
The right choice can make you save lots of money from investment, maintenance (that's very high for this machine) and operating point of view.
 
We also strongly suggest you get a sharpening machine together with it to make you save money, and time, when sharpening is needed.
 
And it will be very often.

 Granulators for plastic recycling

BACK

 

Plastic scraps must be converted to flakes for processing.
Because here we are talking about granulators that will handle dirty stuff, characteristics we should look after are steel used to build wearing parts, and how long it takes to replace blades.
In fact, downtime caused by replacing blades of granulator does effect the cost of final product.
There are two main categories this machine can be divided into: Dry and Wet.
Everybody can understand the difference between the two but now let's see the good and bad points of each one of them:
Granulators running dry are used for all industrial scraps that doesn't need washing.
Dry operation makes machine more productive because it can be equipped with a powerful aspirator (blower) sucking chips out of the grid and, in the meantime, cooling the chamber, the rotor and the material itself.
Maintenance is pretty easy due to the fact nothing will get rusted, including the screws holding the rotating blades.
Shaft bearings will last forever if some lubrication is provided, because water will never get to them.
Granulator running wet (it means with water) will be less productive, comparing two granulator of the same size, but blades life will last a little longer in case of dirty material and, most important thing for us, making friction it definitely has a washing effect, that's exactly what we want. Isn't it ?
So, while in the dry operation friction does create useless, and sometimes unwanted heat, in a wet environment it is very helpful doing what we want it to do.
Cutting and washing together.
At this point it's easy to understand materials used for the construction of the body and the rotor, is an important matter indeed.
Blades are another story because, does not matter what you do, they wear out according to quantity and quality of dirt it arrives to the machine and very little can be done about it.
A pre-washing machine can help to overcome the problem but, still, your feeling will be that time between blades replacement is always too short.
Shape of the blades, steel used, the hardening, the speed of the rotor and another hundred parameters effect blades life so, to buy a granulator is not an easy job because it should be very specific for the situation you are going to be in.
One more important matter is the time it takes to replace blades and how long it takes the fine tuning meaning adjusting the gap between rotating and fix blades.
If you do have a granulator already, you know what we are talking about while if you're just starting, pay a lot of attention to it because, once again, downtime cost a lot of money and every hour you save, as far as maintenance,  decrease you final costs quite a bit.
There are two other factors about the working environment:
Vibrations and noise.
Both of them can be avoided; it is just matter of money so, you better choose to take care of this right at the beginning because later modifications will cost much more.
