GRINDING TECHNOLOGY
TENOVA. INNOVATIVE SOLUTIONS FOR METALS AND MINING
Optimized solutions for comminution within the mining and cement industries
The extensive know-how of our highly qualified engineers creates a solid foundation for the engineering and construction of such equip-ment.
Rapid delivery and assured high quality are guaranteed by TAKRAF’s policy of close co-operation with clients and decades of experience in the engineering, design, fabrication and installation/commissioning of mining and bulk handling equipment and systems.
Through our own in-house fabrication facility, we are also able to offer “Made in Germany” fabrication solutions. Thanks to a skilled and passionate workforce and the adoption of TAKRAF’s integrated management system certified according to ISO 9001, ISO 14001 and BS OHSAS 18001, our Lauchhammer fabrication facility is able to maintain the highest quality standards whilst meeting the most demanding of delivery schedules.
OUR COMPETENCE IN GRINDING AND CRUSHING TECHNOLOGY
TAKRAF, a Tenova company, is an integrated solutions provider to the global mining, bulk material handling, minerals processing and beneficiation industries, offering innovative technological solutions as well as process and commodity knowledge along the industry value chains. With the integration of the well-known DELKOR and Tenova Advanced Technologies (formerly Bateman Advanced Technologies) brand of products into TAKRAF as specialized product lines, our portfolio for the minerals processing and beneficiation sectors has been considerably enhanced.
