The Swiss AlpTransit Line choose Baioni Machinery

Baioni Crushing Plants Spa successfully gained success one year ago when, for the Ceneri base tunnel, the contractor consortium Condotte Cossi opted for Baioni's latest mobile crusher to carry out the excavation. One model repeated four time. Four are the crushers bought to complete the whole work.

Besides the works of the renown Gotthard Base Tunnel in Switzerland, part of the Swiss AlpTransit line, there is another important tunnel: the 15.4 km long Ceneri Base Tunnel in the canton of Ticino from the north portal near Camorino, the south portal at Vezia and in the installations cavern of the intermediate heading at Sigirino. This tunnel with two single-track bores continues the Swiss AlpTransit line south of the  

Gotthard Base Tunnel and is, like Gotthard, built under contract from the Swiss Federal Government by Alptransit Gotthard AG.

The commercial operation of the Ceneri Base Tunnel is planned to start at the end of 2019. Upon its completion it will allow high-speed rail and heavy freight trains, both of which were not possible in the existing steep track over the mountain of Monte Ceneri.

BAITRACK 130/85B AP, fully customized by the contractor for tunnelling purposes, is a complete crushing and screening system that can work large quantity of big size materials, even in confined and narrow spaces like tunnels. It consists of an apron feeder BAIONI AVS 200/1, designed to ease the feeding load by lowering the hopper, a pre-screen BAIONI V122/250. BAITRACK 130/85B AP is built around Baioni's large jaw crusher, the BP 130/85B, which has feed opening measuring 1,300mm x 860mm. The inclined apron feeder delivers the feed load from a low-level hopper to the crusher, with the finest material being pre-screened by the grizzly.

BAITRACK 130/85B AP combines the phase of primary crushing and a first granulometric control, as to reduce the feeding size that will be eventually conveyed outside. The whole unit exploits the crushing capacities of the big crusher to its maximum extent, with a max. production of 450T/h (0-250mm). It is the only one of its kind in the world to be fully driven by electric motors, both for unit motion and production. For the first time ever this self-propelled machine is equipped with an electric motor to power the movement of the tracks, which is especially beneficial where operating space is limited, such as on smaller quarry or demolition sites, but where high performance is  still required.

The mobile crusher can be operated remotely via a standard remote-control system, while a range of optional equipment allows the creation of custom-made units for improved work flexibility. It is also easy to transport and quick to set-up, and complies with safety and environmental standards.

BAITRACK 130/85B represents a totally new concept in tracked crusher design, with the aim of increasing production and reducing operating costs. The advantages over hydraulic versions are said to include: a more energetic performance; lower operating costs; lower maintenance costs; reduced disposal of oil filters; lower environmental impact; and smoother, more accurate drive.

Baioni Crushing Plants is an example of quality evolution and research applied to the production of machinery and plants for crushing, screening and washing quarry and mine aggregate materials as well as machines for recycling demolition material. The company can boast many years of experience in the sector and a deep knowledge of the markets, which guarantee the development and careful production of specific machines and plants for the mining and stone industry at large, offering a complete range of solutions for the entire cycle of industrial treatment.
