RotaCut – reliable and effective treatment of waste water or sludge
If fibers and entanglements in waste water and sludge are causing problems, the RotaCut is the solution. With its contact-based cutting principle the cutter even reliably shreds hair and the finest fibers of (Q-Tips). Foreign matter contained in waste water or sludge is also reliably separated in the RotaCut’s integrated heavy material separator (stone catcher). In this way, the cutter protects pumps and other components in the sewage treatment plant and sewers from damage caused by foreign matter while also preventing clogging. At the same time, the sludge is homogenized, which significantly reduces the costs and effort needed for sludge thickening and sludge dewatering. Thanks to the disintegration of the sludge performed by the RotaCut, the decanter and separators run more evenly, free of disruption, to deliver superior dewatering performance. Integrated into the supply line of the digestion tower, the cutter finely shreds hair and fibers. The RotaCut therefore prevents the formation of entanglements and floating layers, while also preventing disruptions during circulation or sludge removal. Specially adapted designs and sizes are available to make integration into existing sewage treatment plants as straightforward as possible. Comprehensive features and options enable individual adjustment to the on-site situation at the respective sewage treatment plant. Thanks to the RotaCut’s user-friendly service concept, maintenance and parts replacement can be performed quickly on-site. Simply pivot out the cutter head for optimal access; wear parts can then be easily replaced by sewage treatment plant staff or by a service partner.
RotaCut – reliable cutter for industrial applications
The RotaCut, our cutter with an integrated heavy material separator, can be used in a wide range of industrial applications. This cutter offers direct contact between the blades and cutting screen, which allows it to deliver defined cutting performance, which is a major advantage for processing fibrous materials. Moreover, as the RotaCut simultaneously homogenizes the medium, it offers much more than merely pump protection for downstream systems. Medium that has been disintegrated in this manner an also be easily used in additional processes.
In industrial applications, the RotaCut is usually used together with other Vogelsang products, such as rotary lobe pumps, progressive cavity pumps or other cutters, such as the XRipper. For example, in applications involving food wastes, not all materials are suitable for being pumped onward directly after an initial shredding step. Fish, meat and vegetable waste, in particular, often contain coarse fibrous materials that are separated in a heavy material separator.
Two RotaCut models in particular have proven themselves effective in industrial applications: The RotaCut RCX is used in abattoirs as part of the RedUnit in order to meet the requirements of the EU directive on hygiene. Thanks to its compact design and reliable shredding performance, the RotaCut MXL is used on tankers to protect the pumps from foreign matter.
With features and options such as Automatic Cut Control (ACC) and Auto-Reverse function, the cutter is a key product for the shredding required in industrial applications.
