Pellet drying

The plastic pellets are pumped through the piping into the drying equipment. Here, too, hoses play an important role – they control the air supply and heat the pellets.

Norres offers a good alternative to NEO or SIL hoses, namely HT-PUR. These hoses are particularly heat-resistant and they age comparatively slowly, even if the temperature reaches 150°C. The fact that the material shows a 40 percent improvement in mechanical stability and very high resistance to abrasion during heat exposure is an immense advantage.

Transport and distribution

The pellets exit the dryer and are fed through the downstream piping via more hoses. The transparent version of the Airduc 355 hose system is recommended for this step. It allows the process to be observed, so that any errors in production are detected before it is too late. The pellets are subsequently transported onward through the piping to the hose stations.

The hose stations are where other hose applications distribute the product to the various production stations and processes – for instance to the dosing equipment, the suction conveyors on the extruders or the injection moulding machines.
