CPG-13 Vibrating Feeder 350-500 T/H

The CPG-13 Vibrating Feeder represents a critical engineering solution in modern stone crushing operations, designed to handle capacities between 350 and 500 tons per hour. This robust feeding system serves as the essential link between material storage and primary crushing equipment, ensuring consistent material flow while protecting downstream machinery from operational stress. With its substantial 4,880 x 1,370 mm body dimensions and dual 11 kW motor configuration, this model addresses the fundamental challenge that has long plagued crushing facilities: irregular material feeding.

CONSTMACH has engineered the CPG-13 to eliminate one of the most costly problems in aggregate production. When material enters jaw crushers or primary impact crushers in sudden, uncontrolled bursts, it creates a cascade of operational issues. The immediate impact hits the crushing chamber hard, but the real damage extends far beyond that initial point. Conveyor systems downstream become overwhelmed with sporadic material surges, screens struggle to maintain consistent separation, and the entire production line experiences efficiency losses that can reach 60 percent. This isn't just about reduced output; it's about accelerated wear on components that were never designed to handle such erratic loading patterns.

The CPG-13's grizzly section, spanning 1,840 mm in length, performs pre-screening that fundamentally changes how material enters the crushing circuit. Oversized rocks that would normally jam or overload the primary crusher get separated early, while properly sized material flows through at a controlled, steady rate. This selective feeding protects hammer assemblies in impact crushers from catastrophic failures and prevents the thermal stress that builds up in cone crushers and vertical shaft impactors when material arrives in unpredictable waves. The hopper volume options of 30, 45, or 50 cubic meters provide flexibility to match different quarry operations and production schedules.

What makes this vibrating feeder particularly valuable is how it addresses wear patterns across the entire crushing line. When crushers receive material at irregular intervals, hammers and blow bars don't just wear out faster; they wear unevenly. This uneven degradation forces premature replacement of parts that still have usable life in sections less exposed to the sudden impacts. The same principle applies to conveyor systems, where material surges cause one-sided belt wear, roller bearing failures, and drum shaft stress fractures. These aren't minor maintenance issues; they're production-stopping failures that require emergency shutdowns and expensive repairs.

The dual-motor system generating smooth, consistent vibration keeps material moving without the jolting action that can cause structural fatigue in surrounding equipment. At 26,000 kg, the unit's substantial mass contributes to operational stability, dampening resonance that might otherwise transfer through mounting points into the supporting structure. This weight, combined with the engineered vibration profile, creates a feeding pattern that maintains material flow even when dealing with sticky or moisture-laden aggregates that tend to bridge in conventional hoppers.

Production managers understand that screening efficiency drops dramatically when material arrives in surges rather than steady streams. The CPG-13 acts as a buffer, transforming the irregular dump truck delivery cycle into continuous crusher feeding. This consistency allows screens to operate at their designed capacity rather than toggling between overload and idle states. The result shows up in the gradation curves of finished products, which maintain tighter specifications when the entire plant operates at stable throughput rates.

Maintenance costs in crushing operations often spiral upward not from normal wear but from stress-related failures triggered by operational inconsistency. The CPG-13 reduces these costs by extending service life across multiple equipment categories simultaneously. Crusher liners, conveyor belts, screen media, and bearing assemblies all benefit from the controlled loading that proper feeding provides. For facilities processing 350 to 500 tons per hour, these savings compound quickly into substantial annual figures that justify the investment in quality feeding equipment
