SBM has introduced new machines to its JAWMAX and REMAX lines of crushers, targeting the 40-ton range with three tracked models.

The JAWMAX 400/450 are a new design, according to SBM, with options to run as diesel-electric or fully electric, with an optional mains connection. They are powered by a 6.7-litre Cummins diesel and a 200 kVa onboard generator that runs all electrical drives as well as electrically operated hydraulics for lifting cylinders and tracks.

A 110-kW electric motor is tasked to drive the new STE 110-70 jaw crusher, which has been specifically designed for mobile applications. An inlet opening of 1100 x 700 mm, nominal feed material size of up to 700 mm a max lump size of 1000 x 600 x 600 mm and a design for rock strengths up to 400 MPa allow this machine to work in a wide range of applications, from processing of large concrete pieces up to hard natural stone varieties. The machine offers a large stroke of 34 mm and a fully automated monitored gap adjustment of 40 to 160 mm that can be adjusted under load Optional overload protection also helps ensure continuous high production.

The JAWMAX and REMAX 450 - which is based on the REMAX 400 platform introduced in 2018 - both feature a high-performance pre-screening unit that effectively separates contaminated or valuable material, which helps in reducing crusher wear while improving results in terms of quality and output. This new double-deck pre-screen is designed as a circular vibratory screen and is directly connected to the vibrating chute in the feed hopper. The two fractions can be discharged in full or in part as fines, or added to end product as crusher bypass.

SBM says the use of this pre-screen can increase hourly capacity by about 50 tph. At the same time, the JAWMAX 450 using the pre-screen has shown significant improvements in fuel economy, and using the machine plugged into mains power chops energy costs even further.

The JAWMAX is designed for ease of transport, with a transport weight of 39.2 tonnes and slim dimensions. It can be loaded and unloaded easily, and hydraulics position things like the hopper walls, overband magnet and discharge conveyors, allowing the plant to be operational in just over five minutes Operators are supported by the standard multi-functional remote control and setup routines of the intelligent SBM Crush Control system, which also monitors and controls the fully automatic crushing operation along preset parameters. A web-based app allows remote access to important operating and production data.
