The CONSTMACH CHB-400 hydraulic hammer breaker represents a critical solution in crushing plant operations, specifically designed to address one of the most challenging aspects of material processing: preventing primary crusher blockages. Operating within crushing circuits where oversized materials can halt production, this 350 kg unit serves as the first line of defense against costly downtime and equipment damage.
Built around a 68 mm tool diameter and powered by an 18.5 kW electric motor, the CHB-400 delivers consistent breaking force across a working pressure range of 100-150 bar with flow rates between 50-80 liters. This hydraulic configuration ensures the breaker maintains adequate impact energy to fracture large rocks and concrete blocks before they reach the primary crusher's feed opening. The system operates at a maximum reach of 9,000 mm, providing operators with substantial working coverage across the bunker area. With a full 360-degree working angle, the breaker can address material blockages from multiple positions without requiring repositioning of the entire assembly.
The control system combines both radio remote operation and manual valve control, giving operators flexibility based on site conditions and safety requirements. Remote operation allows personnel to maintain safe distance from the crushing area while maintaining full control over breaking operations. This dual-control approach proves particularly valuable during maintenance periods or when working in confined spaces where direct valve access becomes necessary. OMT 25-micron filtration protects the hydraulic system from contamination, while Bezek R2-rated hoses handle the demanding pressure cycles inherent to impact breaking applications.
Structural integrity comes from S355J2 steel construction, a material specification chosen for its high yield strength and excellent weldability. This grade withstands the repetitive shock loads generated during breaking operations while resisting fatigue crack formation. The 700 m² operational footprint accommodates the breaker's movement envelope and provides adequate space for material flow around the breaking zone.
In practical operation, oversized material entering the primary crusher's hopper triggers the breaking sequence. Rather than allowing these pieces to jam the crusher's throat or damage the crushing chamber, the CHB-400 intercepts them within the bunker. The operator positions the breaker tool against the material and activates the hydraulic hammer, fracturing the oversized piece into crusher-acceptable sizes. This intervention eliminates the need for manual breaking or the dangerous practice of using excavators to clear jams from active crushing equipment.
The integration of hydraulic hammer breakers into crushing circuits significantly improves overall plant efficiency. Feed interruptions decrease, crusher wear patterns become more predictable, and operators gain better control over material sizing entering the primary stage. For contractors running mobile crushing operations or fixed installations processing variable feed materials, the CHB-400 provides a cost-effective approach to maintaining consistent throughput while protecting expensive crushing equipment from damage caused by uncrushable or oversized materials.
