Metso’s new NP13 impact crusher
By Andrew Macklin
October 26, 2015 – Metso is introducing the new Nordberg NP13 impact crusher, the newest addition to its range of NP Series impact crushers. Designed for increased safety and performance, NP13 is built for secondary and tertiary applications.
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.
More throughput, less recirculation
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 350 mm (14″) and can be equipped with a 315 kW (400 hp) motor on a single drive. Its maximum throughput capacity is up to more than 20 per cent more than that of the existing NP1213, and it can be installed on a lighter steel structure.
Automation and smart wear part arrangement increase cost efficiency
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 the 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.
Metso innovations make maintenance safe
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 a 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 centralized 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, NP13 offers numerous customization 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.
