Japanese company Tetsugen Corporation has acquired two mobile cone crushers and a Doublescreen screening plant from Sandvik.
The Tokyo-based business, a national leader in slag processing, chose the machines to produce a variety of aggregates. They were selected for their high performance, reliability and low running costs, thanks to a direct link to Sandvik's Global Support Centre, which helps provide aftermarket backup in Japan.
Tetsugen decided to buy Sandvik equipment following a visit to the manufacturing plant in Ballygawley, Northern Ireland, in 2015.
The delegation from Tetsugen was accompanied by Shigehiro Kimura, sales manager for Sandvik Mobile Crushers and Screens in Japan, and a representative from the company’s dealer Imagiire.
When recycling slag material, Tetsugen must produce a number of precise aggregate sizes. The end product is employed by construction and steel companies for the purposes of road construction and use in concrete foundations. To this end, the company currently uses a Sandvik QS331 gyratory cone crusher, a QH331 Hydrocone crusher and a QA441 Doublescreen.
The large slag feed size of 400 mm (16 in) is accommodated by a jaw crusher, which is then fed directly into the QS331. This features the high performance Sandvik CS430 gyratory cone which is easily able to accept feed sizes up to 340 mm (13 in). The material is then processed by the QH331. The cone crushers feature Sandvik’s renowned Hydrocone technology.
Sandvik’s patented Doublescreen technology has two independently adjustable screenboxes which allow for ultimate precision while screening, resulting in high-quality products for Tetsugen’s customers. When performing together in normal conditions, the Sandvik trio’s output is approximately 250 t/hr, helped by the QA441's massive screening area.
