The variopactor, a newly developed reversible impact crusher for medium-hard to hard rock, has a modular design that allows it to be easily adapted to a wide variety of applications. By fitting different rotors, aprons or the optional grinding path, the variopactor can produce gravel, chippings or sand of consistent quality at high cubicity. At the same time, all the parameters that influence product quality, e.g. rotor speed, apron or grinding path position can be flexibly adapted to the specific requirements of customers in the minerals industry. Aprons and grinding paths can be easily adjusted at the press of a button. As an all-in-one solution, the variopactor will prove particularly beneficial to small and mid-sized quarry operators.
Since the housing, rotor and entire crushing chamber of the variopactor are symmetrical, the rotor can be operated in both directions and the direction of rotation changed at any time. Using the rotor in both directions means the blow bars always operate with a sharp edge and minimizes the need to replace or turn them. Besides, thyssenkrupp Industrial Solution is now offering, for the first time, the option of Metal Matrix Composite (MMC) blow bars with high-carbide inlays, which are cast into the matrix material in the main wear zone along the edge of the blow bars where most of the crushing takes place. This gives the blow bars a significantly longer service life than conventional high-carbon chromium steel ones. The matrix material for the MMC blow bars can be made from different steel alloys to suit the application and customer requirements.
The variopactor is ideal for use in small and mid-sized quarries and meets our customers’ demand for reliable, cost-efficient production and high quality products.

The variopactor offers good accessibility from both sides so that wear parts are easy to fit. As maintenance work can be carried out more quickly, downtime is reduced to a minimum. Last but not least, the variopactor is easily integrated into existing equipment to create an efficiency-enhancing system solution.
