Maximizing efficiency in cement and aggregate processing with Komatsu crushing equipment

The cement and aggregate industries rely on efficient and high-capacity crushing equipment to handle large volumes of raw materials while minimizing waste. Komatsu’s range of crushing solutions — including surface feeder breakers, sizers and reclaim feeders — offer innovative technology engineered to enhance efficiency, reduce fines and optimize material throughput. These machines are designed to handle large input sizes, minimize dust generation and improve product shape and size, making them an excellent alternative to traditional crushing methods.

This article explores the unique advantages of Komatsu’s crushing equipment and how it provides cost-effective, high-capacity solutions for cement and aggregate processing.

1. Surface feeder breakers: Maximizing throughput with built-in crushing

Large input size and efficient crushing

Surface feeder breakers combine a chain feeder and primary crusher in a single frame, allowing for efficient material handling and crushing. Unlike traditional crushers, which rely on compression, Komatsu’s surface feeder breakers use tensile breaking technology (which pulls materials apart rather than compressing them), helping to reduce fines and produce uniform material output.

Key benefits of Komatsu surface feeder breakers:

• High throughput capacity: With a maximum capacity of 5,400 metric tons per hour (MTPH), these machines help enable consistent material flow, reducing the need for additional processing stages
• Integrated crushing and screening: Feeder breakers help regulate feed rate while crushing material, simplifying the process and potentially reducing the need for separate feeders and primary crushers
• Versatility across cement and aggregate applications: Surface feeder breakers are designed to handle limestone, aggregates, cement additives and industrial minerals
• Low total installation height: Unlike traditional primary crushers, feeder breakers operate at ground level, potentially reducing the need for extensive civil works
• Efficient equipment utilization: Integrating crushing and feeding into one unit may, in certain applications, result in fewer machines required, potentially leading to lower capital expenditures and maintenance costs

These advantages make surface feeder breakers an ideal solution for cement and aggregate applications where high efficiency and mobility are essential.

2. Sizers: Engineered to produce uniform material with fewer fines in a compact design

Optimized crushing for a range of materials

Komatsu’s primary and secondary sizers use matched velocity technology (MVT) to help break material efficiently while reducing fines generation. This is particularly beneficial in cement and aggregate production, where excessive fines can lead to lost material, increased processing costs and dust issues.

Key advantages of Komatsu sizers:

• Large input size handling: Sizers accept run-of-mine material, processing large lumps into transportable sizes
• Minimized fines generation: Unlike traditional compression crushers, Komatsu’s sizers use tensile breaking, which by pulling material apart rather than compressing it, can significantly help reduce fines
• Customizable output size: Adjustable breaker bars and pick selections allow operators to control product size, potentially reducing the need for secondary crushers
• Reduced risk of clogging: While traditional jaw and gyratory crushers can clog with wet or sticky materials, Komatsu’s sizers are designed to handle high-moisture materials with ease, making them ideal for cement and aggregate applications
• High-capacity crushing: Komatsu sizers, ranging from less than 300 metric tons per hour (MTPH) to less than 3,000 MTPH, provide efficient crushing solutions for various material types

Komatsu’s sizers are designed to improve product quality and reduce energy use by minimizing over-crushing and facilitating consistent, cubic-shaped material.

3. Skid-mounted design potentially eliminates the need for civil works

In many regions, civil construction approvals can be a significant barrier to new equipment installations. Traditional crushers and feeders often require extensive foundation work, which can be time-consuming, costly and subject to the requirement for regulatory approvals.

Komatsu’s skid-mounted equipment offers a major advantage by potentially eliminating the need for permanent civil foundations.

Key benefits of skid-mounted equipment:

• Designed to reduce the need for civil works: Since skid-mounted units rest on a solid surface, they can help lessen the need for concrete foundations, reducing project lead times and costs
• Fast installation and relocation: Skid-mounted machines are designed to be moved quickly and easily, making them ideal for semi-mobile operations
• Simplifies regulatory and planning burden: In many regions, obtaining approvals for civil works can take months or even years, but skid-mounted equipment is designed to help avoid this hurdle, enabling faster deployment
• Flexible deployment: While traditional crushers are usually fixed in place, skid-mounted units can be conveniently relocated as production needs change

By potentially eliminating the need for extensive civil works, Komatsu’s skid-mounted feeder breakers and sizers are designed to provide a cost-effective, rapid-deployment solution for cement and aggregate operations.

4. Reclaim feeders: High-capacity material handling

Efficient material blending and feed rate control

Komatsu’s reclaim feeders play a critical role in material blending and feeding operations. They are designed to enable a steady flow of material to downstream crushers, reducing the risk of bottlenecks in cement and aggregate plants.

Key benefits of Komatsu reclaim feeders:

• Handle a wide range of materials: Reclaim feeders are built to process coal, aggregates, limestone, clinker, fly ash and gypsum, making them highly versatile
• High-capacity operation: With throughput reaching up to 3,750 MTPH, Komatsu reclaim feeders help enable smooth material flow
• Reduced maintenance and downtime: Built with heavy-duty steel components, reclaim feeders are designed to offer an average service life of over 15 years, helping reduce long-term maintenance costs
• Fast deployment: The standard Stamler RF-5 model offers 30-40% faster delivery than customized alternatives, allowing for rapid plant expansion

Reclaim feeders are an essential component of cement and aggregate processing, helping enable a consistent feed rate while minimizing operational disruptions.

5. Lower total cost of ownership (TCO)

Komatsu’s crushing equipment is designed to deliver substantial cost savings across the entire lifecycle of a project. Several design features help contribute to lower TCO:

• Regulates installation costs: Skid-mounted and modular designs can potentially eliminate the need for civil construction, helping you save time and reduce costs
• Fewer equipment requirements: Integrated screening and crushing functions can help reduce the number of machines needed, lowering capital and maintenance costs
• High durability for extended equipment lifespan: Heavy-duty construction and durable wear components extend operational productivity between scheduled maintenance periods, helping to promote a longer service life with fewer replacements
• Energy efficiency: Komatsu's sizers use matched velocity technology (MVT) to help reduce power consumption compared to traditional crushers
• Fast lead times: Standard models like the Stamler RF-5 reclaim feeder can be delivered 30-40% faster than customized alternatives

These factors help make Komatsu’s crushing solutions a cost-effective choice for cement and aggregate producers.
