Reaching 100TPH with AIMIX Crusher Machines: Ideal APJ and APF Models for Limestone Projects

Achieving consistent 100-ton-per-hour output in limestone crushing operations requires precise equipment selection that balances production demands with material characteristics. AIMIX’s APJ series jaw crushers and APF series impact crushers have emerged as preferred solutions for mid-sized limestone projects, offering the perfect combination of throughput capacity, particle shape control, and operational economy. These purpose-built machines address the unique challenges of limestone processing—from its moderate abrasiveness to its cleavage-dominated fracture patterns—while maintaining compact footprints ideal for mobile configurations.

The 100TPH benchmark represents a sweet spot for many aggregate operations, large enough to service commercial concrete plants and road projects yet small enough to permit flexible deployment. AIMIX rock crushers in this range incorporate specialized design features that optimize limestone processing, from wear-resistant alloy compositions to chamber geometries engineered for the material’s compressive strength profile. Their performance demonstrates how targeted engineering can extract maximum value from limestone deposits without over-investing in excessive capacity.

APJ Series Jaw Crushers: Precision Limestone Reduction

Optimized Chamber Geometry

The APJ-E75 model’s 750x500mm crushing chamber features a 27° nip angle and aggressive stroke profile that exploits limestone’s natural cleavage planes. This configuration produces interparticle crushing that reduces fines generation while achieving the 100TPH target with 90kW power consumption. The curved jaw plates ensure consistent pressure distribution across the crushing zone, preventing localized wear common in rectangular chamber designs.

Wear Management Systems

Manganese steel alloys with 18% Mn and 2% Cr composition provide 20% longer service life than standard alternatives when processing abrasive limestone varieties. The rotatable jaw plate design triples component lifespan by enabling position changes before complete wear-out. Hydraulic adjustment mechanisms maintain closed-side settings within ±2mm tolerance, ensuring consistent product gradation throughout wear cycles.

APF Series Impact Crushers: Cubical Product Specialists

Multi-Chamber Rotor Design

The APF-1214 impact crusher’s three-stage impact zones progressively fracture limestone while minimizing recirculation load. The counterflow rotor configuration produces 85% cubical product at 100TPH—ideal for concrete aggregate specifications. Adjustable grinding paths allow operators to fine-tune between maximum reduction (for raw feed) and optimal shape (for finished products).

Material Adaptability Features

When processing clay-bearing limestone, the APF series’ automatic clearing system prevents packing by periodically reversing rotor direction. Integrated rock shelves protect the rotor from direct limestone impact during feed fluctuations, reducing wear rates by 30% compared to conventional designs. The limestone crusher maintains 100TPH output even with 8-10% moisture content in feed material.

System Integration for Maximum Efficiency

Closed-Circuit Configuration

Pairing an APJ-E75 jaw crusher with an APF-1214 impact crusher in closed-circuit creates a complete 100TPH system that yields 98% usable product with minimal oversize. The jaw crusher’s consistent discharge feeds the impact crusher’s shaping action, while the onboard screen returns oversize for additional reduction. This arrangement achieves 15% better energy efficiency than single-stage crushing alternatives.

Mobility Advantages

The track-mounted versions (APJ-E75V and APF-1214V) maintain full 100TPH capacity while enabling site relocation within one workday. Their compact dimensions (under 3m width) permit access to confined urban sites where stationary plants cannot operate. The hybrid power option switches between diesel and electric modes, reducing fuel costs by 40% at grid-connected locations.

The AIMIX APJ and APF series demonstrate how purpose-designed crushers can optimize limestone processing economics. Their balanced approach to throughput, product quality, and operating costs makes them particularly suited for contractors and aggregate producers needing reliable 100TPH performance without the complexity of oversized systems. As limestone remains the backbone material for construction projects worldwide, these machines offer a compelling combination of German engineering principles and Chinese manufacturing value—delivering European-level performance at accessible price points.
