Design and Engineering Excellence

The design of the MR130Z Blow Bar is intrinsically linked to the innovative engineering of the MR 130 Z EVO2 impact crusher. The crusher unit features a large 1,300 mm x 900 mm inlet, allowing it to accommodate feed materials with maximum dimensions of 1,100 mm x 700 mm. The blow bars are mounted on a robust rotor, which is driven by a powerful electric motor with a crushing power of 250 kW. This setup generates tremendous force upon impact, necessitating a blow bar that can withstand repeated high-impact shocks without premature failure.

A significant feature that enhances the service life of the MR130Z Blow Bar is the crusher’s Continuous Feed System (CFS). This intelligent system monitors the load on the impact plates and the rotor, automatically regulating the frequency of the vibrating feeder and pre-screen to ensure a consistent and even flow of material into the crushing chamber. By preventing uneven feeding and cavity flooding, the CFS ensures that the blow bars are subjected to a steady stream of material, which promotes optimal crushing action and significantly reduces wear. This not only extends the operational life of the blow bar but also contributes to lower operating costs per ton.

Furthermore, the MR 130 Z EVO2 utilizes innovative C-shaped blow bars (also referred to as hammers or plate hammers). This specific geometry is designed to maintain an optimal impact crushing effect over an extended period. The C-shape allows for better utilization of the material, as it can be rotated to expose a fresh, sharp edge after the initial wear face becomes dulled. This feature effectively multiplies the service life of each blow bar, offering excellent value.

Durability, Material, and Serviceability

Built to withstand the most demanding conditions, the MR130Z Blow Bar is manufactured from high-quality, wear-resistant alloys. The exact metallurgical composition is tailored to the specific application, whether for crushing abrasive natural stone like limestone or tougher construction waste like reinforced concrete. This focus on material science ensures maximum resistance to impact and abrasion, directly translating to longer service intervals and reduced downtime.

Serviceability is a cornerstone of the EVO2 design philosophy. Replacing the blow bars is a secure and streamlined process, facilitated by the “Lock & Turn” safety system. This system ensures that maintenance personnel can safely access the rotor and replace the blow bars or clear blockages. The ability to perform these tasks quickly and safely is crucial for maximizing the plant’s operational availability, making the MR130Z Blow Bar not just a durable part, but also a user-serviceable one.

Application Versatility and Performance

The MR130Z Blow Bar is central to the crusher’s renowned versatility. It is engineered to handle a wide range of materials, making it an ideal choice for both quarry operations and construction sites. Its typical applications include:

• Processing soft to medium-hard natural stone at both primary and secondary crushing stages

• Recycling construction and demolition waste (C&D), such as concrete rubble, bricks, and asphalt

In recycling applications, the MR130Z Blow Bar demonstrates exceptional capability in processing construction demolition materials while maintaining high throughput and consistent product quality. The performance of the MR130Z Blow Bar is fundamental to achieving optimal results, ensuring that the final product meets stringent standards for grain shape, size distribution, and cleanliness, which are essential for high-quality concrete and asphalt mixes.

Conclusion

In summary, the Kleemann MR130Z Blow Bar is far more than a simple wear part; it is a precision-engineered component that is vital to the reliability, high productivity, and cost-effectiveness of the MR 130 Z EVO2 mobile impact crusher. Its advanced design, coupled with high-wear-resistant materials and the support of intelligent systems like CFS, ensures superior performance in a variety of demanding applications. For operators seeking to maximize their crushing potential and minimize operating costs, selecting the genuine MR130Z Blow Bar is a decisive factor for success. The blow bar’s robust construction, combined with its innovative C-shaped design and compatibility with advanced crushing technologies, makes it an indispensable component for modern crushing operations demanding both efficiency and reliability.
