Does your business need to convert abrasives and sedimenting melts, such as catalysts and suspensions, into pastilles for safe and easy transportation, storage, dosing, and reprocessing? The Rotoform 4G AS can help.

Based on IPCO’s market-leading pastillation technology, the Rotoform 4G AS incorporates design innovations for the efficient granulation of abrasive and sedimenting melts.

Efficient pastillation of abrasive and sedimenting melts

Our patented Rotoform pastillation process produces consistently sized pastilles directly from the melt to help you maximize competitiveness through improved quality and productivity.

The Rotoform 4G AS has been designed with modifications to both equipment and process to minimize separation and friction. As a result, you can apply this market-leading solidification solution to a range of abrasive and sedimenting melts. Typically, these contain solids, in the form of a powder or ground material, of a severely abrasive nature, many of which it was previously impossible to form into pastilles. These include:

Nickel catalysts (containing up to 30% sharp edged nickel powder)
Sulphur bentonite
Stearate
Suspensions of wax and solids

How it works

Rotoform 4G AS

Like all Rotoform lines, the Rotoform 4G AS combines a drop depositor with a steel belt-based cooler. Drops of molten product are deposited onto the moving belt by means of a perforated rotating shell that turns concentrically around a heated stator.

The heat of the drops is transferred via the steel belt cooler to water sprayed underneath, resulting in controlled cooling. The solidified droplets are discharged from the steel belt as uniform hemispherical pastilles.

Very low vapor/ gas emissions

More about the Rotoform family

Benefits

Designed for abrasive and sedimenting melts

The Rotoform 4G AS is adapted to convert melts containing abrasive powders into granules of a consistent shape and size:

Low-volume processing – fewer solids in the system at one time reduces the risk of separation
High-velocity product flow – meaning less time available for separation to occur
Elimination of ‘dead corners’ where sediments might otherwise separate
Minimal moving parts for reduced friction
