McLanahan has introduced a Mini Direct Drive Crusher — the Mini DDC-Sizer — as a cost-effective means of fine crushing at small throughputs in mineral processing plants. Developed as a result of customer demand, the Mini DDC-Sizer is suitable for crushing for final product or as preparation for heavy media separation of fine particle sizes down to 3–4mm. The McLanahan Mini DDC-Sizer is suitable for pilot plants or processing battery minerals such as lithium and graphite. Other applications include agglomerated iron ore, phosphates, and heavy metals extraction.
Conceived as a hybrid between traditional McLanahan double roll crushers and toothed sizers, this sizer can be wheel-mounted for easy access or installed as a fixed machine. Its direct drive system, with right-angle gear reducers, allows for installation in low-headroom areas and provides a compact footprint. Additionally, roll adjustment plays a key role in the Mini DDC-Sizer’s design, as both roll shafts can be adjusted forward or backward to provide versatility in crushing settings and wear compensation.
The crushing surface of the Mini DDC-Sizers can be hard-face welded or laser clad with a variety of wear resistant materials and textures to build up or maintain the roll profile, increase the life of wearing surfaces and maintain product quality. The McLanahan modular assembly design also allows for quick changeout of the sizing rolls when maintenance is required. Wear liners are symmetrical, bolted in place for easy replacement and made from abrasion-resistant material.
Additional Mini DDC-Sizer features include:
- Direct mechanical drives that provide reliability and ease of maintenance
- Fluid couplings for overload protection
- Large diameter to feed size ratio for a positive gripping action
- Large diameter crushing rolls to maximise the wearing surface area providing longer service life
- Drive system components sourced from globally recognized OEMs
The Mini DDC-Sizer is the latest in the McLanahan range of DDC-Sizers, which are operating in markets around the world. Like all McLanahan’s machinery, the Mini DDC-Sizer can be engineered to suit a site’s specific requirements. Adaptations include a variety of roll designs, tooth configurations and drive orientations.
