Pellet Durability Testing
Tekpro - Model Holmen NHP300 - Inline Pellet Durability Tester
The Holmen NHP300 Pellet Durability Tester is ideally suited to a busy, quality focused mill. Samples are automatically taken from the production line, the machine tests the pellets by agitating them with air at a fixed 70mBar pressure, returns them to the line, and a PDI result is provided to the NHP300 control software, or to your current mill management software without manual input from the mill operator during the test phase.
Tekpro - Model Holmen NHP200 Series 2 - Automated Pellet Durability Tester
The Holmen NHP200 Series 2, is our flagship pellet durability tester used worldwide for calculating the Pellet Durability Index (PDI) of feed and wood pellets by simulating the pellet transportation environment from mill to trough.
Tekpro - Model Holmen NHP100 - Manual Pellet Durability Tester
The Holmen NHP100 is our entry level Pellet Durability Tester which is designed to be easily transported around different testing locations. The NHP100 operates by loading a manually weighed sample of pellets into the test chamber, which cascades them in an air stream at 70mBar, causing the pellets to collide with each other and the perforated hard surfaces of the test chamber. After the test cycle the pellets are manually removed and weighed to obtain a ‘Pellet Durability Index’ (PDI) reading.
