Plastic granulators are a tool that help one get smaller granules of plastic by cutting it and reducing the size to make them more manageable. Plastic Granulators are seeing a consistent growth in demand especially for reduction in size. These small sized granules can be directly sold to the market or used in other plastic processes. If you are looking for a plastic granulator machine, then you must keep in mind that you want something that will facilitate the generation of recycled content, guarantee effective management and ultimately increase your profits.
Here are some things to consider while selecting a granulator for chopping scrap plastics-
Know Your Application
Your intended application will determine what kind of granulating machine you should buy. The material you need to granulate to a particular size and bulkiness and its amount are one of the first things to take note of. The physical size and form of the parts would have to be clearly defined. The material itself should be considered the next. Different types of plastic react differently to this process such as PVC, glass-reinforced plastic or polypropylene- all have different reactions. Also, when feed streams are being utilised, they should be assigned percentages. When you’re handling roughly 95% sprues and runners in addition to the sporadic purgings, it’ll be more effective to have a solution for your sprues and runners while allocating another system for the purge. A one size fits all machine is impossible to find in the world of granulation. And using the same machine on different materials and for different purposes can result in operational inefficiency and cost you a lot more in the long term. Understanding the important aspects of your application first will make it easier for you to define the size of the chamber, right kind of rotor and amount of horsepower required to do the job efficiently and effectively.
A Look at Granulator Parts
One of the most essential components to consider while selecting a granulator is the rotor. Whether to go for an open rotor for processing fragments with slim walls in which materials flow effectively or a closed rotor design to get large, thick scraps. There is also the staggered rotor, a hybrid of the other two types that has more cuts for each revolution.
Another factor to consider is horsepower requirement which is directly related to the engagement between the fly knife and the bed knife. In order to create the scissor cut, the two knives are offset against each other. The number of bed knives a granulator contains can range from one to even four to enhance cutting action. Also, consider chamber size and shape, of which can affect the size of cuts the knives can make with each action.
