The purchase of such specific machinery as grinding mills can be a real headache if a series of fundamental factors are not taken into account for the perfect functioning of the entire recycling process. The wide variety of shredding mills that exists today makes them capable of shredding almost all types of plastics and we can choose between different powers, speeds and / or sizes for our company. Choosing between one or the other will always depend on the type of waste that we want to recycle.

What is a grinding mill?

Plastic shredders are a type of specific machinery that allows us to reduce large plastic pieces into much smaller volumes with a low cost in terms of investment, giving large volumes of plastic a second chance.

The grinding mill is made up of different elements that we must take into account to optimize the performance of our transformation process.

Elements to consider

• Inlet mouth

One of the most important parts of a grinding mill is its inlet. Depending on its size, our plastic transformation process can accommodate smaller or larger volumes. It is essential to know exactly what type of material we will go through our mill to adapt the entrance to it.

On many occasions, we focus the purchase of our machinery on a budget, but we must have adequate foresight to have a fully functional mill for our process.

• Blades

The use of blades and their condition is another of the most important points and that we must take into account when choosing our grinding mill. The use of blades that are not very sharp or in poor condition and even poorly adjusted, make our machinery consume more electricity and its production drops considerably.

Gester is a specialist in the manufacture of blades, as well as professional sharpening, so having experts in the field will give us that “plus” for a perfect operation and guarantees.

In addition, we must also consider the number of blades that we will need, as we have spoken in the previous point, an exhaustive planning will be essential to avoid making mistakes in the choice of our crushing machinery.

• Electricity and control

Another aspect that is taking the most strength both at the business level and technological advances, is the software and the added “extras”.

Today we can find great advances such as remote control, accounting of daily processes, frequency, acoustic damping to reduce noise, portability, automated systems, anti-blockage systems … endless improvements that can be important in our business model.

• Size

It is undoubtedly something very basic, the choice of the grinding mill based on the maximum size that our plant can have, but that a bad choice can take its toll on performance.

• New or second hand machinery

When choosing our mill, we can choose two options: new machinery market or revised second-hand machinery.

There is a wide market for revised and guaranteed used machinery that achieves very considerable economic savings on investment.

Companies like Gester dedicate their sale of second-hand machinery in the best possible conditions, reviewing them and guaranteeing their correct operation, so that the choice of a used crusher mill may be the best possible choice for our plastic transformation.
