on the market; the uniformity and shape of the pellets also ensure they have a lower moisture content,” it claims. This, it says, eliminates the need for time-consuming post-drying of the product. The system also has very good handling
characteristics. The cutting chamber is designed to be opened and closed quickly and safely with one hand. Cleaning, assembly and commissioning requires minimal effort, so the product can be changed rapidly. The long life
process a wide range of polymers at high rates, according to Maag. It is used, for example, in production of raw materials, compounds and masterbatches, wood/polymer composites, elastomers, and hot-melt adhesives, including recycling lines. Maag says a key feature of the Pearlo unit is that
it produces very uniform spherical pellets. “This not only results in an excellent appearance, which clearly distinguishes the pellets from other products
of the cutting tools is also claimed to be unique. “Thanks to the innovative design of the knife head, knives and cutting chamber, fast agglomerate-free start-up is possible within a very wide processing window,” says Maag. “The longer process length of the knives results in a long service life, and drastically reduces the downtime as well as the number of blade changes required.”
Engineering decision According to Maag, Hexpol TPE’s choice of Pearlo was mainly based on process engineering reasons and particularly those connected with pellet quality and process stability. It says start-up on changing product takes considerably less time compared to
