The Vogelsang RotaCut Sludge Grinder is an economical solution for sludge laden with rags, heavy solids, and other debris.

The RotaCut is a highly effective solution for eliminating heavy solids that can cause damage to pumps, valves, and other equipment. Unlike simple shredding methods, it reduces wipes, rags, plastics, and fibrous materials into small confetti-sized particles. Additionally, it features a built-in “rock trap” that captures and removes hard objects like metal or stone before they reach the grinder. This not only extends the life of the grinding blade but also keeps the objects from interfering with the system.

Designed to address the vulnerability of pumps and dewatering equipment to damage caused by sludge containing hard solids, fragments, and debris commonly found in wastewater sludge, the RotaCut is an ideal solution. It can be placed in front of such equipment to protect them. Furthermore, it can be used for sludge conditioning prior to dewatering equipment or digesters, as it creates a homogenized slurry.

The RotaCut offers various sizes and is suitable for a wide range of wastewater applications, including:

1. Primary sludge
2. Thickened sludge
3. Sludge transfer
4. Dewatering equipment feed
5. Digester feed and recirculation
6. Septage and FOG receiving

One of the standout features of the RotaCut is its service-friendly design. All maintenance tasks can be completed within minutes without the need to disconnect any piping. Most models feature a hinged cover that grants easy access to the cutting blades and screen. The cutting screen is available in multiple material options, patterns, and hole sizes. Additionally, the screens are reversible, allowing for a fresh cutting surface without the need to purchase a new spare screen.

Vogelsang has a range of specialized grinders and macerators ideally suited for the challenges associated with wipes, rags, and other debris at wastewater treatment facilities. In addition to the RotaCut grinder, Vogelsang also provides the XRipper twin-shaft grinder, which uses two hardened steel monolithic ripper rotors to cut and shred debris in the sludge waste stream.
