Blow bars, impact plates and side liners for Metso NP13, NP15, NP20, NP1110, NP1213, NP1313, NP1315, NP1415, NP1520, NP1620 and NP2023.
Blow bars, impact plates and side liners for the NP range, NP1110 through NP2023 plus the short NP13, NP15 and NP20 designations. Impact work is less about tonnage and more about how the rotor is loaded, and the wear parts show that clearly.
An impactor tells you what it is doing through its wear pattern. Reading it takes one photograph and saves a set of bars.
High chrome resists abrasion and chips under impact. Martensitic steel resists impact and wears faster in abrasive rock. A bar that shatters at the first lump is the wrong alloy for a coarse primary feed, not a bad casting. For mixed feed with some oversize, the honest answer is usually martensitic and a shorter life, or a ceramic insert at a higher price. We do not sell high chrome into a primary impactor and call it an upgrade.
Even wear across all bars means the feed is distributed and the rotor is balanced. One bar worn far more than the others means the feed is entering on one side. A single deep groove on one bar is usually one contaminant, not a wear problem. Bars worn at the leading edge only means the bar is too hard for the duty and is breaking down rather than wearing. Each of these has a different fix and only the last one is a metallurgy question.
The gap between the bar and the plate is the product size control, and getting it wrong costs twice. Too wide gives coarse product and lets lumps hammer the bars instead of being thrown. Too tight wears the plate through and loads the rotor. After a plate is replaced the gap has to be re-set and checked, not set once and forgotten. We ask for the gap the plant runs when a plate set is ordered.

NP1110, NP1213, NP1313, NP1315, NP1415, NP1520, NP1620, NP2023, plus NP13, NP15 and NP20. Bars and plates are listed per model above.
We can quote them. They cost considerably more and only pay back on a highly abrasive feed with a controlled top size. On a feed with oversize they tend to fail at the insert. We will say when the arithmetic does not work.
Yes, and sometimes it should be. Tell us the feed and the failure mode and we will recommend a grade. That recommendation may differ from the original part number, and we will explain why.
