Komatsu sizers are helping to redefine performance standards and expand the boundaries of where sizers can be applied for maximum impact.
In the competitive world of mining and material processing, efficiency, reliability and cost-effectiveness are paramount.
Komatsu sizers offer a robust solution that’s designed to handle a variety of materials with high efficiency and minimal downtime.
The machines are high-performance double-roll crushers designed to excel in both hard and soft rock applications. With a capacity of up to 3000 metric tonnes per hour, they can be used as a primary or secondary crusher to reduce material size and prepare it for further processing.
Equipped with crushing blocks or picks, depending on the specific application, Komatsu sizers are engineered to efficiently crush material using compression, tension and shear forces.
Crushing efficiency
Proven to manage even the toughest materials, the sizers operate effectively in mine sites with compressive strengths exceeding 260 MPa.
Primary sizers incorporate wear-resistant pick technology, built from Komatsu’s extensive experience with feeder breakers, shearers and continuous miners.
Material is processed using a combination of gravity and rotational downforce from the heavy-duty centre sizing shafts.
Additionally, the sizers feature a breaker bar beneath the rolls to control product sizing in three dimensions. A key benefit of this technology is its ability to efficiently screen undersized material through the rolls, preventing over-crushing, reducing fines generation and minimising waste.
Durable design
Komatsu offers a range of primary and secondary sizers tailored to meet the specific needs of an operation.
Primary sizers are designed to handle large lumps and produce a consistent product size that can be easily transported. These machines are particularly effective with wet, sticky materials that often cause problems for other types of crushers. Secondary sizers are optimised for reducing fines while maintaining high throughput, due to their matched velocity technology and replaceable teeth segments, helping to extend the machine’s lifespan.
Sealed outboard bearings help to minimise water and dust ingress, reducing the need for water sprays and helping to maintain a cleaner work environment.
The no-clog performance of Komatsu’s primary sizers, even with challenging materials, enables consistent production and reduces the risk of operational delays.
Cost effective operation
One of the standout benefits of Komatsu sizers is their low total cost of ownership. The robust design and durable wear components help extend operational productivity between scheduled maintenance periods, resulting in lower running costs and longer machine life.
Komatsu sizers feature replaceable teeth and segmented wear parts, allowing quarries to replace the worn components instead of the entire unit. Customers can also rotate high-wear areas with low-wear areas within the crushing chamber.
Smart technology
Komatsu sizers are equipped with smart machine LINCS technology that provides real-time monitoring and proactive maintenance capabilities. Features like resistance temperature detectors, vibration sensors and torque-limiting clutch slip detection help protect the machine from damage and reduce downtime, so operations remain efficient and productive.
Customisation and flexibility
Every quarry operation has unique requirements. Komatsu sizers offer the flexibility needed to meet these demands with options like mechanically adjustable roll gaps, various pick designs and metallurgical cladding.
These machines can be customised to handle different material sizes and consistencies to optimise crushing processes.
The sizers can also be rail-mounted with wheels for a maintenance rollout feature. Configurable motor options are available for either singular or dual drives to suit a range of space configurations and power requirements.
Whether it’s a large-scale open pit, an underground mine, tunnelling/civil aggregates or cement applications, Komatsu sizers provide a flexible solution. •
