The ultimate for cutting and shredding

The RotaCut - the pioneering technology, developed in the 1990s, is the essential workhorse in many systems and plants today. This is the reason why it's often copied by competitors. As a high performance wet cutter with an integrated heavy object separator, it's the perfect solution for problems involving coarse and fibrous foreign matter and foreign objects in liquid media. Foreign objects are separated while coarse and fibrous materials are chopped up, thus making the liquid medium homogeneous. The RotaCut keeps all foreign objects away from pipe system, prevents pump clogging and assures a trouble-free operation of the system. Even if defined cutting grades are needed- e.g. in the disposal industry - the RotaCut, thanks to its proven cutting concept, is the ultimate choice.

How it works

Separation variants:
The RotaCut is available with 4 different heavy object separators. We have the perfect one for your application:

• Cyclone separator, with heavy object separator
• Inline, intake and discharge are arranged in-line
• MXL, ideal for mounting onto a vehicle
• MX, the small compact unit

Application areas / types of liquids:
The Vogelsang RotaCut has been proven under the harshest conditions and is therefore ideal for the following applications:

• sewage
• sludges
• bio-suspensions
• co-enzymes
• food industry
• food scraps
• slaughterhouse waste
• fish industry
• potato pulp
• carcass disposal
• meat fillings
• paper and cellulose industry
• waste disposal industry
• oil sludge
• agriculture
• manure slurries

This makes the RotaCut indispensable

The right choice for every application

Whether small and mobile or mounted as a stationary unit in a pipe system: The variety of models within the RotaCut range offers the appropriate solution for any problem regarding pumping and protection from foreign objects or for a defined cutting grade. The RotaCut, which was introduced onto the market by Vogelsang over 10 years ago, has been and continues to be optimised as it has become the indispensable component in pumping systems for abrasive, heavily charged liquid media. The RotaCut is available in four versions using different materials, drive systems, cutting screen sizes and pump combinations. The RotaCut, with its excellent features, is exceeding all customers expectations.

Advantages and features

• Prevents clogging, while homogenising the liquid media.
  Damage to downstream pumps and pipe systems are therefore prevented.
  
• Shredding grade is variable.
  By regulating the volumetric flowrate and/or the drive speed, cutting screen and rotor geometry, the cutting grade can be adjusted as desired.
  
• High throughput with minimal drive power.
  Economical with the best cutting.
  
• Blockage protection through the Auto-Reverse function.
  Where other macerators fail, the RotaCut keeps on cutting.
  
• Clean and easy removal of separated foreign objects.
  Through the large-size opening in the RotaCut hatch all foreign objects can be quickly and easily removed.
  
• Simple and quick parts in location.
  Simply open the cutting head and all wear parts are accessible.
  
• Easy and economical to maintain.
  Both sides of the cutting screen may be used. Minimal work is needed for maintenance and service.

It's all in the cut!

The exchangeable cutting knives made of tool steel are optimally arranged on a 4-wing knife rotor, they are held against the cutting screen by a self-adjusting pressure system. The cutting screen made of hardened steel with a specially developed geometry may be used on both sides. The constant contact between the rotating knives and the stationary cutting screen assures the highest efficiency with respect to function and economy. The shaft seal between the gearbox motor and the cutting head is provided by a mechanical seal with an oil buffer chamber.

LifeGuard and the RotaCut

The following LifeGuard factors increase the lifetime of the RotaCut.

Cutting knife

• the optimal arrangement yields the best cutting results
• made of specially hardened steel
• self-sharpening
• self-adjusting

Cutting screen

• made of specially hardened steel
• optimal geometry
• usable on both sides
  

ACC (Automatic Cut Control)

• Optimal cutting pressure, adjustable from outside the RotaCut.
  ACC allows the optimal cutting pressure to be selected while the machine is in operation and is automatically kept constant.

The difference when compared to other macerators and double-shaft shredders is the cutting principle. Because of the constant contact between the knives and cutting screen everything from thick pieces of wood to extremely fine fibers (e.g. hair) are reliably cut and shredded.
