The new Nordberg NP13 impact crusher can provide significant improvements in productivity

Designed for increased safety and performance, Metso stated that NP13 is the perfect choice for secondary and tertiary crushing applications.

The NP13 is the second addition to the renewed NP Series, which started with the NP15 launched in 2014. The new Nordberg NP13 uses the same design as the NP15 but for smaller capacity requirements.

Vincent Schmitt, product manager for NP Series impact crushers at Metso, said: “Performance, profitability and maintenance of the crushing plants are at the heart of this new crusher.”

To improve crushing efficiency and produce more end products with less recirculation load, the 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.

The NP13 accepts feed material up to 350mm and can be equipped with a 315kW motor on a single drive. Its maximum throughput capacity is up to 20% more than that of the existing NP1213, and it can be installed on a lighter steel structure.

Wear parts and automation

The number of different side liners has been cut by nearly half compared with the NP1213 - the NP13 only requires seven different liners. This wear part arrangement means more flexibility in the use of the side liners and less need for parts in stock.

Metso developed an advanced two-part rear frame for the NP13. The extra large opening of the new frame gives greater access to the breaker plates during wear part replacement

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.

Metso said that 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 provides a very rigid assembly that allows the use of blow bars with ceramic inserts, even with coarse feed material.

Safe maintenance

To make maintenance safer and easier, the 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 the NP13 ensures the safe replacement of breaker plate liners. This feature 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 self-rotation rotor (SRR) system is the centralised point for the setting adjustment and blow bar change, and further increases safety during maintenance operations. Thanks to its automated turning, the rotor provides a safe environment for changing the blow bars without any risk of injury for the operator.

In addition to these benefits, the NP13 offers numerous customisation options to help customers fit the crusher to their specific technical and business needs. These include a fully hydraulic setting adjustment, third breaker plate, drive equipment, sensors and automatic greasing, among others.
