Effective wet maceration

Pioneering design with long-term effectiveness The RotaCut® macerator for homogeneous media and reliable plant protection Whether in the food industry, pulp and paper industry or in abattoirs, effi cient maceration of coarse matter and fi brous material in fl uid media forms a key component of processes in many sectors. Smooth operation of biogas and sewage treatment plants depends on reliable heavy material separators and maceration of solid and disruptive matter in fl uid media. Macerators also signifi cantly impact the cost-effectiveness of agricultural businesses and disposal companies. Vogelsang developed the RotaCut macerator 25 years ago, and continues to prove its reliability – under the most challenging conditions – around the world. From fecal matter, liquid manure and organic suspensions to potato pulp, food waste and abattoir waste through to sewage and oil sludge – the RotaCut’s universal suitability for an ever-expanding range of sectors and applications is constantly tested – and its effectiveness validated. Its decisive advantage: the RotaCut separates critical heavy matter before the medium being prepared reaches the macerator’s cutter head. Thanks to clever details and sophisticated design, the RotaCut can even chop down hair and industrial fi bers, thereby reliably protecting all downstream components from foreign matter, as well as fi brous and solid matter. Innovative screen geometry Our engineers have developed software that calculates the specifi c optimal geometry of cutting screens designed for use with a specifi c medium – for all screen sizes and reduction ratios. This ensures that the cutting screen for your application has been individually tailored precisely to the medium you intend to process. Users therefore enjoy optimal geometry and the best possible results for their application. To augment cost-effectiveness as well, all cutting screens can be used on both sides. RotaCut® advantages at a glance • Reliable maceration of fi brous and coarse matter • Foreign matter protection for all downstream components • Lower mixer and pump power requirements thanks to more homogeneous and fl owable medium • Fully automatic, interruption-free and low- maintenance operation thanks to Automatic Cut Control (ACC) • Fully automatic monitoring of the unit as well as automatic fault elimination with PCU (optional)

04 | 05 Principle and technology Size reduction technology The RotaCut has many applications as a macerator. Fibrous and coarse matter are fi ltered through the cutter head of the RotaCut with the fl ow of the pump medium. The sophisticated cutting-screen geometry and an innovative blade-guiding system enable reliable maceration and an extremely smooth cutting result. The fl uid and the solid matter it contains are turned into a pumpable, homogeneous suspension. The RotaCut is also a very effective tool for homogenizing heterogeneous media. It can be used in the food industry, in slaughterhouses, biogas plants and wherever suspensions with stable consistencies are required. The RotaCut even safely macerates hair and industrial fi bers. Protection from foreign objects An important function of the RotaCut is protection from foreign objects by means of an effective heavy material separator. Stones or metal parts that cannot be mace- rated are safely retained and channeled into a collecting container. Thus, important components such as pumps, pipework, etc., are thoroughly protected. The principle The RotaCut combines two functions in a single machine. It separates and macerates, which transforms fl uids laden with fi bers, solid matter and foreign materials into pumpable suspensions. While the medium continually fl ows through the RotaCut, heavy material such as stones or metal parts are separated out by gravity. They are easily removed later through a cleaning port. All fl oating and suspended substances within the medium (fi bers, hair, bones, wood, entangled material, whole plant silage or grass) are transported to the cutting screen by the liquid fl ow and macerated by rotating, self-sharpening cutting blades. The medium is homogenized at the same time. Blade and rotor construction The blades inside the RotaCut are made of wear-resistant, martensitic stainless steel and positioned against the RotaCut cutting screen in a self-adjusting manner. Thanks to the clever design of the blade holder in the rotor there is constant contact between the blades and cutting screen. Combined with the optimized blade arrangement, this guarantees low-vibration during operation, along with high effi ciency and cost-effectiveness. Simple maintenance Like all Vogelsang machines, the RotaCut is designed for low and easy maintenance. All wearing parts, including the blades, are easily accessible and can be replaced in a few simple steps. The functional principle of the RotaCut® The medium fl ows steadily through the RotaCut macerator. Foreign matter (stones, metal parts, etc.) is separated out based on its size or weight and can be easily disposed of later via a cleaning port. All fl oating and suspended substances within the medium (fi bers, hair, bones, wood, etc.) are transported to the cutting screen by the liquid fl ow and chopped by rotating, self-sharpening blades.

While the medium flows continuously through the RotaCut, heavy material, such as stones or metal parts, are separated out by gravity while fibers and solid matter are evenly macerate while the medium is homogenized. Examples of tested RotaCut® applications: • Preventing rags and layers in digesters • Protection from foreign objects as well as waste- water treatment during vacuum extraction of small wastewater works or at sewage stations • Maceration of abattoir waste and by-products, in- cluding treatment prior to sanitation in accordance with EU Directives • Protects tankers from foreign matter and fibers in sludge, liquid manure, food waste, etc. • Increase in efficiency and gas yield in biogas plants through digestion and homogenization of organic suspensions • Protection of mobile pump systems from foreign objects and coarse matter

Consistent pressure for maximum performance ACC automatic cutting pressure control for uninterrupted performance ACC – Constant performance, long service life Automatic Cut Control (ACC) consistently ensures excellent cutting performance by the RotaCut. There’s no need for manual maintenance as the ACC automatically adjusts the cutting blades of the RotaCut and keeps the necessary contact pressure constant – as high as necessary and as low as possible. This means the pressure can be adapted to the medium at any time without interrupting operation, which not only reduces power consumption requirements, but also reduces wear and signifi cantly extends the lifetime of the cutting blades. Always informed with ACC plus: The optional ACC plus feature enables online monitoring of the RotaCut for the RCQ and RCX series. An external display and / or the control graphically indicates the status of the cutting blades and informs you when the blades require changing, so you can plan spare part orders and maintenance well in advance. Thus, ACC systems provide effi ciency gains and the greatest degree of automation for continuous use applications. ACC advantages at a glance • No manual blade adjustment required; fully automatic, uninterrupted operation • Contact pressure can be adapted to the medium at any time without interrupting operation • Low operating costs thanks to minimum wear and low power consumption • Optimal results due to consistently high cutting performance and constant size-reduction ratio

Performance Control Unit (PCU) If multiple pumps and grinders are grouped together into one unit, the PCU checks operation of each component, as well as other parameters. It ensures optimum communication between individual pumps and grinders and continuously monitors their loads. Individual components are controlled to ensure that the unit as a whole achieves optimum results. The PCU automatically detects faults early on and rectifi es them before they pose a problem. PROFINET enables the control system to communicate rapidly with higher-level systems, thereby enabling central collection and evaluation of detailed operating data. The OPC UA interface enables platform-independent data exchange or access for remote maintenance. The user- friendly Human Machine Interface (HMI) incorporates visual elements for intuitive user navigation, providing rapid overviews of operating statuses, data and settings. Operators benefi t from fully automatic control of operating parameters that can respond independently to various situations.Moreover, because PCU monitoring isn’t limited to any one location, it can even control pumping stations located at a distance, and unmanned sewage treatment plants. Auto-Reverse function Auto-reverse enables the RotaCut to react promptly when it comes into contact with coarse and hard extraneous materials. The system detects any blockage in the mace- rator and reverses the rotational direction of the blade rotor. Another cutting attempt then occurs from the other side of the disruptive matter. This process is repeated until the blocking matter is macerated. Another helpful function: Automatic reversal of the direction of rotation on a regular basis means that the pair of cutting edges in use at the screen and blades is always sharp, as it has been ground on the reverse side beforehand. As the operator, you benefi t from optimal cutting perfor- mance and simultaneously reduced power consumption. Thanks to the Auto-Reverse function, the system detects any blockage in the cutting head and reverses the rotational direction of the blade rotor. This process is repeated until the blocking matter is macerated. Advantages of the Auto-Reverse function at a glance • Increased effi ciency through reduced power requirements • Lower operating costs • Reliable operation thanks to automatic blockage elimination PCU advantages at a glance • Reduced maintenance thanks to autonomous operation and automatic remedying of disruptions • Fully automatic and situation-dependent control of operating parameters provides maximum effi ciency • Longer service life means lower operating costs • High throughput
