What if your crushing circuit could deliver higher throughput, fewer fines, and lower operating costs all while reducing infrastructure demands? In this article, we explore how Komatsu is helping cement and aggregate producers rethink material processing with integrated surface feeder breakers, sizers, and reclaim feeders built for performance, flexibility, and sustainability.
Efficient comminution is critical to cement and aggregate operations, and the choice of crushing and feeding equipment directly affects throughput, operating costs, and product quality. Komatsu offers an integrated portfolio of surface feeder breakers, primary and secondary sizers, reclaim feeders, and skid-mounted systems designed for the demands of bulk material handling. Across these solutions, Komatsu emphasizes controlled material flow, reduced fines, lower infrastructure requirements, and improved total cost of ownership.
By combining mechanical durability with efficient control philosophy, Komatsu positions its equipment to support higher productivity, lower energy use, and more sustainable processing in quarry and plant environments.
1. Surface feeder breakers: Integrated crushing and feeding for high-volume operations
Komatsu’s surface feeder breakers combine a drag chain feeder and primary crusher in one compact, skid-mounted unit. Using tensile fracturing rather than compression, they control feed, reduce material size, and generate fewer fines while using less power. With tensile strengths far lower than compressive strength on average, this method can improve energy efficiency while delivering consistent output sizing.
Key advantages: Surface feeder breakers can handle feed rates up to 6600 tph and top-size run-of-mine material up to 59 in. They combine feeding and crushing in one machine, simplify plant layouts, support materials such as limestone, additives, industrial minerals, and aggregates, and reduce civil works through a low-profile, ground-level installation. Resulting in a practical alternative to conventional jaw or gyratory crushers where mobility, throughput, and reliability matter most.
These features make feeder breakers especially attractive for high-volume applications that need semi-mobile equipment, dependable performance, and efficient size reduction with less waste.
2. Primary and secondary sizers: Controlled size reduction with minimised fines
Matched velocity technology for controlled reduction
Komatsu’s primary and secondary sizers use matched velocity technology to align roll speed with incoming material, improving throughput and reduction while limiting fines. Self-cleaning impact teeth help sized material pass freely, reducing buildup and supporting consistent performance. Compared with high-speed crushers that create excess fines or slower systems that encourage grinding, this design helps preserve usable product and improve downstream processing.
Performance highlights: Sizers accommodate large run-of-mine feed as well as secondary or tertiary material, with capacities ranging from under 300 - 3000 million tph. They allow adjustable product sizing, limit over-grinding, and perform reliably with high-moisture, clay-rich, or sticky material that can clog traditional gravity-fed crushers.
That combination of size control, dust reduction, and reliability makes Komatsu’s sizers well suited to cement and aggregate plants facing variable feed conditions.
3. Going mobile: The skid-mounted advantage that reduces civil construction bottlenecks
Traditional crushing installations often require major civil works, adding cost, delays, and permitting complexity. Komatsu’s skid-mounted systems offer a modular alternative that can be placed on compacted surfaces or simple supports, reducing the need for foundations and accelerating project schedules.
Benefits: Factory-assembled, tested units can be deployed quickly, often with fewer regulatory hurdles than fixed installations. Offering relocation flexibility through crawler, wheel, or skid-mounted options, ideal for shifting production needs, phased expansions, and haul-distance optimisation.
By eliminating fixed foundations, these systems can shorten time to production, lower capital exposure, and simplify expansion or temporary deployments.
4. Reclaim feeders: Regulated feed control for continuous plant operation
Consistent material flow is essential to efficient crushing and blending. Komatsu’s reclaim feeders regulate volumetric material flow from stockpiles to crushers, mills, or loadout systems, helping plants maintain continuous operation and accuracy across processing lines.
System capabilities: Komatsu reclaim feeders handle materials including aggregates, limestone, ores, clinker, fly ash, gypsum, and coal. Capacities range from 200 - 4000 million tph, and heavy-duty wear components support long service intervals, with average operating life around 15 years. Standardised machine models offer significantly faster delivery times than custom-built alternatives.
For producers trying to scale quickly, this mix of durability, feed control, and faster delivery helps prevent bottlenecks and improve overall plant performance.
5. Designed for what’s next
Komatsu’s crushing technology is designed not only to improve current operations but also to support a more sustainable future for cement and aggregate producers.
By reducing energy use, waste, and environmental impact, these systems help producers pursue regulatory and ESG goals while maintaining productivity. Their modular, mobile, low-impact design aligns with the changing needs of construction, infrastructure, and mining markets.
For companies aiming to raise throughput, cut downtime, and control costs without waiting on major construction or long permitting cycles, Komatsu’s line of feeder breakers, sizers, reclaim feeders, and skid-mounted systems offers a compelling solution.
