    Top Features

    Barmac® B7150SE™ is available as stationary, mobile or portable

    Barmac® B7150SE™ is the medium-sized model of Barmac® B Series™ family. Thanks to precise reduction, it is performing best at third or fourth stage of the crushing process.

    Generally, Barmac® is utilized in demanding crushing operations in construction, industrial minerals, metallic minerals and waste recycling applications. The crusher is available as stationary, mobile or portable version.

    Superior product quality

    As other models in the same family, Barmac® B7150SE™ uses rock-on-rock crushing process where the feed material is utilized to crush itself. This autogenous crushing process results in homogenous, cubical-shaped end products that have less moisture.

    In addition to rock-on-rock crushing, Barmac® B7150SE™ can be equipped with metallic anvils on request. In anvil solution the rock-on-rock cavity ring is replaced with an anvil ring, and the rocks are thrown against metal anvils instead of a rock bed. This improves reduction ratio and enables finer end products, but the downside is slightly higher wear costs because the anvils must be replaced from time to time.

    Less downtime

    Barmac® B7150SE™ is energy efficient. Especially when equipped with the traditional rock-on-rock cavity ring, the crushing process requires less energy since rocks also crush each other.

    In addition, wear rates tend to be lower, which extend the intervals between maintenance and service, resulting in increased uptime.

    Barmac® B7150SE™ with an anvil cavity ring calls for maintenance a little more often, but the benefit is more effective size reduction.

    Simple to install and maintain

    Whenever service is required, Barmac® B7150SE™ has been designed to be easy to maintain.

    An automatic lubrication handles the daily greasing of the main shaft.

    An access to rotor parts is easy via an inspection door. Maintenance lifting tools, such as a roof lifter and rotor service arm speed up servicing internal workings and rotor changes.

    Barmac® B7150SE™ has minimal foundation requirements due to the low static and dynamic forces in operation, which ensures easier installation.

    Safer operation

    With Metso IC™ crusher automation, Barmac® B7150SE™ can be connected to any plant automation system. This enables centralized control, allowing the operator safely to control and adjust the operating parameters according to production needs from a distance.
