Semi-toothed blow bar for Terex MAGNUM 120

The semi-toothed blow bar, part number 30076392, functions as a primary impact element within the rotor assembly of industrial crushers. By rotating at high speeds, this component strikes incoming feed material such as rock, concrete, or debris, effectively breaking it down into smaller, manageable sizes. Its semi-toothed geometry is engineered to balance initial impact force with the desired output particle size, allowing for versatility across various crushing applications.

This component is specifically configured for the Terex MAGNUM 120 mobile impact crusher. The dimensions of 304x440 mm ensure a precise fit within the rotor housing, which is necessary to maintain rotational balance and prevent operational vibration. Proper installation of this part is essential for the efficient processing of large volumes of material in quarrying, mining, and recycling operations.

Blow bars are critical wear components in impact crushers that transfer kinetic energy to the material being processed. Their configuration and mass distribution directly influence the throughput capacity and the gradation of the final product. Regular inspection and timely replacement of these bars are standard practices to maintain the integrity of the crushing chamber and protect the rotor from imbalance or secondary damage.
