Minprovise launches jaw crusher for Australian market


Mining services company Minprovise has launched a new jaw crusher in its range — the RXJ-Series.

Replacing the ASJ Astro Jaw, the RXJ-Series, or REXE-Jaw, is manufactured by Japan’s EarthTechnica, which is a subsidiary of global engineering and manufacturing company, Kawasaki Heavy Industries.

The REXE-Jaw features a redesigned crushing chamber and a new set adjusting device. These enhancements deliver an “industry-leading crushing capability and a significantly improved work efficiency”.

Users will benefit from reduced running costs as well as increased productivity, according to Western Australian-based Minprovise.

The crushing chamber features crushing blades aligned in a V shape, and a mechanism to smoothly discharge crushed rock with the stroke of a swing jaw. As a result, the crushing capacity has been improved by approximately 15 per cent over conventional models equipped with a wedge-shaped crushing chamber.

A new set adjusting device has been provided as standard for adjusting particle size. With this addition, the adjusting time has been shortened by a third to a quarter of the time required to adjust manually.

Earth Technica has also designed a simple yet robust structure, with parts subject to frequent wear being strengthened to realise a unit that can easily withstand years of use.

Minprovise believes that the RXJ series will “provide Australian operators with additional choice at the premium end of a market now dominated with low cost but often unreliable options whilst maintaining a competitive price point.”
