Granulation and size reduction have evolved as important steps in total production. Granules are useful in plastic procedures and are sold as commodities. The need for granulation has risen with the increasing cost of materials and greater customer demands to include recycled materials in the product. It is now viewed as an important marketing opportunity, in addition to providing a cost-saving method.

A granulator machine calculates scrap plastic into a smaller, more manageable size. Today, granulators, also known as plastic grinders, are not just lying useless in the corner of your plant. The importance of an efficient granulating system has been realized to manage your material cost and raise recycled content in the products.

The most important task for efficient granulation is to choose the right granulator according to your application type. You must determine a few things, like your parts’ size and shape. This will include the style of your material, its size, and how much you need to granulate.

It is important to note that there is no all-in-one granulator. Depending on your material and application, you need a different granulator type for better efficiency and cost-saving. Therefore, it is important to determine what kind of rotor, chamber size, and horsepower you will need to undertake the granulation work.

Once you have determined your plastic feed stream, the next task is to consider the specific granulator components. First is the rotor, which has three basic types: closed, open, and staggered. If you want to grind large and thick parts, a fast rotor machine is for you. For thin materials, an open rotor is best suited to ensure effective flow. On the other hand, staggered rotor designs are a hybrid between open and closed rotors, enabling more cuts per revolution.

Granulators can help processors be more efficient and profitable. Another important consideration is the granulator’s chamber size and shape. It would help if you chose between a divergent and a standard chamber. A common room will be efficient for thick-walled parts and materials. A tangential feed section is more appropriate for bottles, buckets, and other large materials.

Next is the screen, which is very important as the part goes to the net after being cut into pieces. The ultimate particle size depends on the screen’s size, which usually ranges from .25″ up to 2″. Screen size matters as smaller holes lower the throughput, while larger holes let more plastic pass through. After determining your feed stream, you must set up the machine to find the correct granulator. The final stage in the process is the evacuation of the granules. Again, there are various methods to do this, and the most common is Airveyor discharge.

You have an efficient granulator configured specifically for your application. Due to advances in cutting technology, machine design, and energy consumption reductions, many cost-effective solutions are available for granulation and size reduction to cut material efficiently today. Thus, you only needto to determine your feed stream and learn the features and workings of different types of granulators to find the ultimate granulator machine that is best for you.
