The inclusion of primary and secondary sizers in engineering consultant Tenova Takraf’s product offering enables it to integrate its own crushing machines into complete mining solutions for its clients.
Introduced in April at the bauma 2016 trade fair in Germany, Tenova Takraf’s primary sizer product range covers inlet sizes from 2.5 m to 4 m with a throughput of up to 10 000 t/h, while the secondary sizer range covers inlet sizes from 2 m to 4 m with a throughput of up to 3 500 t/h. Both ranges are suitable for the comminution of all material types.
Special focus was placed on attributes such as ease of maintenance, reduced downtime and the long service life of equipment during the sizers’ initial development. As a result, Tenova Takraf’s sizers offer unparalleled levels of maintenance efficiency and service life, allowing for quick and easy changing of crushing segments, as well as the use of advanced wear-resistant materials such as hard-faced segments and tungsten picks. Other features include an inching drive for roll maintenance, which significantly increases safety, a heavy-duty drivetrain system and an efficient oil lubrication system, which ensures greater environmental sustainability.
Rock fragmentation and abrasion are critical elements with regard to material characterisation and Tenova Takraf is, moreover, able to conduct material tests across several conditions at its in-house test facilities in Germany. The determination of material crushability and wear behaviour is analysed by specialised test machines and the results can then be employed to assist in sizer selection. In this way, customised wear predictions of the crushing tools can also be determined.
Tenova Takraf is a supplier of equipment and systems for openpit mining and bulk handling. The international company offers technological solutions, as well as process and commodity knowledge, along with various industry value chains, which are supplied in South Africa, where Tenova Takraf Africa is based in Kempton Park.
