CPI-1415 Primary Impact Crusher 350-400 T/H

The CPI-1415 primary impact crusher represents a robust solution engineered for operations requiring high-capacity processing of soft to medium-hard materials. This machine stands out in quarrying and mining applications where efficient primary crushing is essential. With a rotor measuring 1,400 x 1,540 mm, the crusher delivers production rates between 350 and 400 tons per hour while maintaining the cubical product shape that downstream processes demand.

What makes this model particularly effective is its substantial reduction ratio. Many crushing plants struggle with bottlenecks at the secondary stage, but the CPI-1415 minimizes this concern by achieving significant size reduction in a single pass. This capability translates directly into improved plant throughput and reduced operational complexity. The machine accommodates feed material up to 1,000 x 1,000 mm, giving operators flexibility when processing varied rock sizes from the quarry face.

The rotor assembly forms the heart of this crusher's performance. CONSTMACH constructs the rotor through arc welding followed by thermal stress relief, a process that eliminates internal stresses and enhances structural integrity. Manganese steel impeller bars handle the continuous impact forces, wearing predictably over time rather than failing catastrophically. These bars can be replaced during scheduled maintenance without compromising the rotor body itself. Supporting this assembly are large spherical self-aligning roller bearings that compensate for minor misalignments while handling the substantial rotational forces generated by the 315 kW motor.

The crusher's frame incorporates thick side sheets reinforced with manganese liners in high-wear zones. This design approach concentrates wear-resistant material where impact and abrasion occur most intensely, extending service life without unnecessary weight. The inlet features a generous opening protected by chain curtains that absorb rebounding material, preventing damage to upstream equipment and reducing safety risks. Discharge occurs through unobstructed openings that prevent material bridging and maintain consistent flow.

Operational adjustments are handled through a hydraulic setting mechanism that eliminates the manual effort typically associated with crusher maintenance. Operators can modify the adjustable breaker bar position to fine-tune product sizing without stopping production for extended periods. This system reduces downtime and allows quick response to changes in feed characteristics or product specifications.

At 28,000 kg, the CPI-1415 requires substantial foundation work, but this mass contributes to operational stability. The weight dampens vibrations and maintains alignment under the continuous shock loads inherent to impact crushing. Primary impact crushers like this model serve operations where reduction ratio and product shape matter more than absolute fineness, making them ideal first-stage equipment in multi-stage crushing circuits processing limestone, dolomite, gypsum, and similar materials.
