Wobbler Feeder / Feeding For Crusher

Material handling in crushing and screening operations often faces a critical challenge: how to maintain consistent flow while dealing with problematic materials. Wet clay, sticky aggregates, and mixed particle sizes can bring conventional feeding systems to a halt, causing costly downtime and maintenance headaches. This is where wobbler feeders prove their worth, offering a robust solution that keeps material moving regardless of conditions.

CONSTMACH wobbler feeders stand out in the market through their carefully engineered design approach. At the heart of the system lies a series of rotating elliptical bars that create a distinctive wobbling motion. This isn't just for show – the motion serves multiple purposes simultaneously. As material travels across these bars, smaller particles naturally fall through the gaps while larger pieces continue forward. This built-in screening capability means your crusher receives a more uniform feed, and you're already removing fines before they even reach the primary crushing stage.

The technical specifications of CONSTMACH wobbler feeders reflect years of field experience. The body liners use HARDOX 450 steel at 10mm thickness, which translates to exceptional wear resistance in abrasive environments. You're looking at handling capacities between 150 to 200 tonnes per hour, suitable for most primary crushing applications. The unit measures 4,000mm by 1,000mm and weighs in at 18.5 tonnes, providing the mass and stability needed for consistent performance under heavy loads.

Power delivery comes from fourteen 3kW GAMAK brand motors running at 1500 rpm. This multi-motor configuration distributes the workload evenly across the feeder deck, reducing stress on individual components and extending service life. The heavy-duty gearbox handles the torque demands of processing dense, compacted materials without breaking a sweat. Walking platforms come standard, making daily inspections and maintenance tasks safer and more efficient. Steel legs provide a solid foundation, and the entire assembly is built to withstand the vibration and impact forces typical of aggregate operations.

What makes this feeder particularly valuable is its performance with difficult materials. Sticky, moisture-laden feeds that would clog a conventional grizzly or apron feeder move through with minimal intervention. The rotating bars don't provide a surface for material to build up on, and the constant motion prevents bridging. Clay content that would normally require manual breaking is handled automatically. This capability alone can justify the investment in operations dealing with high-clay overburden or wet recycled materials.

The adjustable settings allow operators to fine-tune performance based on current material characteristics. Gap spacing between bars can be modified to change the cut point for material passing through versus material moving forward. This flexibility means the same feeder can handle different material types across seasons or as quarry faces change. Feed rate adjustments ensure downstream equipment operates at optimal capacity without surge loading.

Maintenance requirements stay remarkably low compared to more complex feeding systems. The mechanical simplicity means fewer wear parts and straightforward servicing procedures. When wear does occur, HARDOX liners can be replaced without specialized tools or extended downtime. The robust construction handles the punishment of 24/7 operation in demanding environments, from Arctic mining sites to tropical aggregate plants.

In primary crushing applications, consistent material flow directly impacts overall plant efficiency. Surges overload the crusher, while gaps in feed waste capacity. CONSTMACH wobbler feeders deliver that steady, regulated flow that keeps crushers running in their sweet spot. The pre-screening function reduces the volume of material entering the crusher, which can extend liner life and reduce power consumption. For operations where every percentage point of efficiency matters, these advantages add up quickly.

The cost-effectiveness extends beyond the initial purchase price. Lower operating costs, reduced maintenance frequency, and improved plant utilization create ongoing value. When you factor in the elimination of downtime from material flow issues, the return on investment becomes clear. This is equipment that pays for itself through reliable performance rather than requiring constant attention to keep running.
