To support the company's One Komatsu global strategy and the integration of legacy companies into the Komatsu brand, sizers, reclaim feeders and surface feeder breakers have rebranded to Komatsu natural yellow (from Joy orange). The newly rebranded yellow MVT-II 600 sizer was displayed in the Komatsu booth at CONEXPO-CON/AGG 2023.
For waste reduction in the quarry and cement production process, the Komatsu MVT-II 600 sizer uses matched velocity technology (MVT) to generate less fines in product and help minimize waste production. The process uses tension — rather than compression. Timed center-sizing rolls enable teeth to mesh together and control product size in three dimensions.
The no-clog crushing of the MVT-II 600 can crush a combination of hard abrasive minerals and wet sticky material. Engineered for performance, the MVT-II 600 has replaceable bolt-on roll wear segments and durable pick technology. Shaft assemblies include cast wear segments with replaceable teeth.
The MVT-II sizer can be installed where many other crushing technologies would not fit. Designed for mobile or underground applications with a small machine envelope, secondary sizers can often be installed between conveyor transfer points to reconcile material handling issues. The sizer can potentially reduce the number of crushing or dump stations required and can work with very large lump sizes to increase crushing ratios.
