The new Nordberg NP13 uses the same design as the NP15 but for smaller capacity requirements.
“Performance, profitability and maintenance of the crushing plants are at the heart of this new crusher,” says Vincent Schmitt, Metso’s product manager for NP Series impact crushers.
To improve crushing efficiency and produce more end products with less recirculation load, NP13 features a steeper feed angle. This increases material penetration into the rotor and makes the discharge curve less sensitive to blow bar wear, enabling more consistent end products over time without having to change blow bars. NP13 accepts feed material up to 350mm and can be equipped with a 315kW motor on a single drive. Its maximum throughput capacity is said to be up to 20% more than that of the existing NP1213, and it can be installed on a lighter steel structure.
The number of different side liners has been cut by nearly half compared with the NP1213. NP13 only requires seven different liners. This clever wear part arrangement means more flexibility in the use of side liners and less need for parts in stock.
Thanks to Metso IC crusher automation, product quality is both predictable and consistent. The Metso IC crusher automation system is available for NP13 as well as for all of Metso’s crushers to give accurate control of the crusher parameters for a high-quality product and improved plant profitability.
The wide selection of blow bars ensures that customers always have the right tool, regardless of the abrasiveness of the crushed material. Metso’s triple-wedge blow bar attachment system is the easiest on the market and provides a very rigid assembly that allows the use of blow bars with ceramic inserts, even with coarse feed material.
To make maintenance safer and easier, NP13 has a new two-part rear frame that combines safety with easy, wide access. The operator can choose which way to open the frame, depending on where access is required.
The removable breaker plate cassette on NP13 ensures the safe replacement of breaker plate liners. This patented innovation consists of a removable assembly so that the breaker plate liners can be changed in a safe place outside the crusher. An additional spare cassette can be prepared in advance to further ease and speed up liner changes.
The NP13 maintenance bridge is an innovative and professional solution that provides safe and easy access to both the highest side liners and the rotor. This means that the operator performing the maintenance is always working under safe conditions.
The patented Self-Rotation Rotor (SRR) system is the centralised point for the setting adjustment and blow bar change, and further increases safety during maintenance operations.
