TAKRAF is continuing to boost its market share in the comminution sector after receiving a contract to supply two high pressure grinding rolls (HPGR) to a cement plant in Turkey.

Demand for HPGR technology from the mining sector has been on the up in recent years as companies, especially those in the iron ore game, look to increase the grades of their product to satsify the increasingly ‘green’ requirements of consumers in China and elsewhere.

TAKRAF’s HPGR machines have been designed with maintainability in mind, the company said.

“A clear target to achieve this goal is the reduction of downtime, which includes integrated maintenance tools and a focus on the changing of wear parts,” the company said.

Furthermore, the machines boast a load optimised frame structure, which ensures effective operations under varying load conditions.

In this application in Turkey, each HPGR incorporates rolls with a diameter of 1,800 mm, a width of 1,600 mm and a weight of more than 50 t. Two variable frequency drives with a combined output of around 3,000 kW provide the power to process more than 1,000 t/h.

Additionally, each roll’s surface is protected from wear by weld-hardfacing.

The company recently installed a specialised welding machine for this very purpose, which is able to guarantee consistent quality throughout the entire hardfacing process and ensures the hardened rolls are able to meet the demands placed upon them, TAKRAF said.

Engineering will be conducted by a joint team based at TAKRAF’s production facilities in Lauchhammer, Germany, together with members of the Cologne team. The machines will be manufactured in Lauchhammer, with delivery scheduled for the first half of 2019.

“We are pleased to be part of this project, which marks an important milestone in respect of TAKRAF’s ongoing strategy to develop within the comminution equipment market and ensure that our clients are best-served to increase efficiency within their operations,” Dr. Frank Hubrich, CEO of TAKRAF, said.
