goovi® is the name of a newly developed multi vibrating screen from thyssenkrupp Industrial Solutions. “The name says it all: goovi ensures good vibrations in secondary and tertiary screening in the gravel and crushed stone, mining, mineral processing and recycling industries. A new patented drive technology in combination with an innovative control system provides a significant increase in operational flexibility, product quality and performance, coupled with greatly reduced weight and height.”
Achim Schönfelder, Head of Product Line Screens and Feeders at thyssenkrupp Mining Technologies: “With the goovi, all vibration modes (circular, linear and elliptical) can be realised in one machine, allowing flexible adaptation to changing job requirements and material properties. In addition, the low height of the goovi facilitates simple installation in existing plants.”
The goovi is driven at four different points, one on each side front and back, resulting in an optimum stress distribution in the side walls. It also uses fewer rotating parts than conventional screens, which translates into significantly lower weight and height as well as reduced maintenance and wear. Two or three standard unbalance motors are installed at each drive point, so each goovi is driven by a total of 8 or 12 motors, depending on size, which are synchronised via a patented PLC supplied with the machine.
With the patented control system, speed and flow direction can be steplessly adjusted so that all important operating parameters can be optimally adapted to the requirements of production at any time. In addition, with the goovi it is possible to react flexibly to changes in material properties (eg moisture) during operation and optimise the processing of difficult-to-screen materials. Different product qualities can be saved in recipes and retrieved as required at the touch of a button via the touchscreen supplied.
The goovi can also be integrated into control loops for product optimization. There is a preset cleaning function for the removal of clogged particles. The goovi is fully digitised and can be integrated into a higher-level control system, paving the way for Industry 4.0 in processing plants. Peter Berlitz, Product Manager Screens at thyssenkupp Mining Technologies: “To optimise costs and delivery times, thyssenkrupp has developed a range of standard machines. The single-deck and double-deck versions are available in six different widths and four different lengths with a maximum screening area of 26 m². However, due to the straightforward modular design, custom solutions tailored to a particular application can also be supplied.”
