OverviewPrimary sizers use wear-resistant pick technology developed from shearers, continuous miners and feeder breakers to reduce oversized lumps and control product size. Multiple pick designs and adjustable breaker bars enable adaptation to hard, abrasive or sticky materials while maintaining a compact machine envelope suitable for mobile and underground installations.
Features and benefits- High capacity - Engineered to handle large lump sizes and deliver high crushing ratios, reducing the need for multiple downstream crushers or dump stations.
- Compact installation - Fits into restricted envelopes where other crushers cannot be installed, lowering installation costs and enabling mobile or underground use.
- Wet and sticky material handling - Integrated cleaners and frame design reduce material build-up; effective on clay, marl and tunnel spoil.
- Efficient powertrain - Uses helical gear reducers, robust power transmission components and automatic lubrication to extend service intervals.
- Ingress protection - Outboard bearings with custom seals minimize water and dust ingress when sprays are used for dust suppression or washing.
- Replaceable wear elements - Exchangeable picks extend component life compared with disposable alternatives.
- Instrumentation - Bearing temperature, vibration monitoring and locked-rotor detection improve reliability and protect against tramp metal damage.
