Granulators

Searching for Plastic Granulators? Granulators are a key component in today’s increasingly sophisticated plastics, pharmaceutical and recycling industries. They are used to reclaim plastic scrap reducing it to granular particles to facilitate the removal of contaminants and for further processing. They prepare powdered granule for tabletting and in the recycling industry they recycle plastic scrap found in the environment so it can be used again. Given the increasing amount of plastic in our environment and the rising cost of plastic resins, using a granulator to reclaim and recycle plastic is not only cost effective, its environmentally friendly.

Choosing the Right Granulator

Choosing the right granulator depends on a variety of things the most important being your requirements for granule size, quality and volumes. Granulators come in a variety of sizes, with different feed hopper sizes, different horsepower rates, different rotor sizes and designs, and different throughput rates. The quality of the granulator is of paramount importance. While the initial cost of the granulator is a consideration, it cannot be the deciding factor. While a granulator might be cheaper upfront, the manpower, maintenance and longevity of an inexpensive unit could end up costing you more in the long run. Here are some other factors to consider:

Model Type: there are several different kinds of granulators and choosing a design type depends on your process setup, i.e., space requirements, connection requirements, etc., and the material that you have to granulate. There are central models, beside-the-press grinders and below-the-press designs. Different models feature larger feed or infeed hoppers, lower hopper heights, interchangeable components, different rotor configurations and different cutting chambers designs for easier access.

Feed Hopper Size and Design: granulators are typically sized according to the feed hopper size which can range from as small as 4″ x 6″ inches, to as large as 100″ x 12 feet. The trend is that bigger is better depending on what you are trying to recycle. Hopper type is also something you should think about. While hopper type machines are ideal for most materials, long scrap material can be a problem.

Power Source: some plastic granulators are powered by diesel and others that are hydraulic based. Most are powered by electric motors ranging anywhere from 2 to 600 hp.

Throughput Rates: for a recycling system to achieve maximum throughput rates and to be energy efficient, it cannot have undersized throughput components that will create costly bottlenecks. When there’s a bottleneck, not only is there a backup in discarded plastic scrap, there is a loss of money and operator time. Most granulators are rated in terms of pounds per hour ranging from 200 to 10,000 lb/hr. Inside the cutting chamber, volume and rotor speed are obvious factors impacting throughput, but the real key is the number of cuts per revolution of the rotor. Unless the granulator is designed to cut quickly and efficiently, the material will end up spinning around inside the cutting chamber without being converted into something useful. A granulator that cuts the most material per revolution will reduce and size more plastic per hour.

Ease of Maintenance: when there is a machine failure it is crucial that you keep downtime to a minimum. One of the ways to reduce downtime is to make sure that the granulator’s cutting blades are easily accessed and changed. Modern designs take this into account most often by allowing operators to preset blade tolerance outside the cutting chamber.
