The Vogelsang XRipper

The twin-shaft grinder that's changing the service and repair model

Traditional twin-shaft grinders are built with two long cutter stacks made of blades and spacers – as many as 150 blade/spacer sets on the largest grinders. When it comes time to service these things – or worse, when they jam or fail, the blades and spacers come apart easily for repair. But that’s when things go sour. We’ve heard maintenance guys tell us that putting our competitor’s twin-shaft grinder blades back together is a nightmare. Getting the spacers just right takes hours. And if you don’t see that you’ve misaligned something soon enough, you’re going to have to take the whole thing apart and start over.

So Vogelsang did it differently. Instead of the nasty stack of blades and spacers, the XRipper Twin-Shaft Grinder was engineered with two monolithic Ripper Rotors, each made from one solid block of steel. No spacers, nothing to align or stack. We also design the XRipper with no lower bearings, and an easy-to-replace cartridge mechanical seal.

Unlike a traditional twin shaft grinder, the XRipper grinder is easy to maintain. Everything can be done inline without removing any connected piping. Simply remove a few retaining hex nuts and the unit can be lifted vertically while the flanges and housing remain connected to the piping.  

The XRipper's ripper blades are both removed at the same time and come off in solid sections versus individual pieces like ordinary twin shaft grinders. Typical routine service such as changing ripper blades takes only a fraction of the time required to service a typical twin shaft grinder. In addition, there are no cartridge style parts that require factory refurbishment.

Vogelsang also has made it easy to replace a traditional twin-shaft grinder with drop-in replacement for many common grinders in the market.
