GNR K Series Cubicizer Crusher

The GNR K series cubicizer crusher shapes flaky/elongated grains into cubical ones and lowers the Flakiness Index. Capacity 45–250 tph, rotor 1000×750–1550×1800 mm, feed 120–210 mm, 45–160 kW. It improves grain shape for concrete/asphalt and raises manufactured-sand quality. The GNR K series cubicizer crusher shapes flaky/elongated grains into cubical ones and lowers the Flakiness Index. The aim is not reduction but improving grain shape for concrete/asphalt and meeting ASTM C33-style shape requirements. It raises manufactured-sand quality. Technical data Working principle Cubicizing is a function, not a separate crusher class; in practice a high-speed rotor/impact breaks and reshapes flaky grains (a relative of the VSI and special cone). Stage: tertiary/shaping. Material and application Suitable: crushed aggregate with a flaky/elongated grain problem — mainly shape correction for concrete/asphalt spec; limestone and medium-abrasive rock. Note: under very high-silica continuous abrasion, wear-part cost rises and ceramic/high-chrome is needed. Flakiness rises as feed size grows and speed drops. Reduction and wear (TCO) Reduction is low (for cubicizing); the target metric is a lower Flakiness Index and a higher cubical ratio. Wear parts are blow/shaping bars and liners: high-chrome or ceramic-MMC by material. As cubical product is premium-priced under concrete/asphalt spec, the added product value offsets part cost in the TCO. The cubicizer completes manufactured-sand quality alongside the VSI and washing chain; we supply the line and concrete batching from a single source. S: What does a cubicizer do? C: It shapes flaky/elongated grains into cubical ones and lowers the Flakiness Index. S: Does it reduce? C: Little; its main function is shaping. S: Why is cubical aggregate important? C: Concrete strength and asphalt performance require shape specs (ASTM C33/EN). S: How does it differ from a VSI? C: It is in the same shaping family; the cubicizer is a dedicated shaping configuration. S: How can I get a quote?
