Pergande Rotor Granulation(IPT-Pergande GmbH)

The process:
The rotor granulator is characterized by a rotating base which causes such specific centrifugal and shear forces to act on the granulate nuclei as to produce spherical granules. The granules grow like snowballs by accumulating successive layers of the continuously injected formulation powder with simultaneous spraying of the agglomeration liquid. The sufficiently large pellets are continuously removed from the process in a downstream screening fraction.

Product properties:

Spherical agglomerates
Shell-like structure
Controlled release
Particle diameter: ±0.1mm
Variable: small to large particle size distribution
High mechanical strength of the agglomerate
Not susceptible to abrasion
Suitable for closed-loop control and automation.

Process principle:

Powder Agglomeration liquid
Agglomeration of powder on granulates
Liquid bridges between powder particle and agglomerates.

Pergande – Rotor Granulation Process for Pigment-Granules-Manufacturing

The Process:

The Pergande rotor granulation for pigment manufacturing is the result of intensive research and development in cooporation with our cutomers.
For the first time, the process combines a continuous mixing process for powdered bulk goods.
The required agglomerate liquid will be dosaged continuously during the mixing process.
The rotor garnulator are charaterizid by a rotating bottom.
The selective centrifugal- and shearing stresses are affecting the granulegerms. The outcome of this is a spherical granule.
Through lowering of the rotor disk the (centrifugal stress) product will be carried out.
The above mentioned process will be completed by an established PERGANDE fluidized bed spray process and security sieving.

Product properties:

Higher bulk density/ smaller volume
Spherical agglomerate
Dust free granules
Particels diameter: 0,5 - 1 cm (according to your demand also bigger)
Good starage and shipment abilities
Good resistance of granules
Improved handlings qualities for end consumer

Instead of conventional technology, PERGANDE offers the technology of tomorrow, customized to meet specific customer requirements.

The focal point of our corporate strategy is on continual research and development in our state-of-the-art technology center.

We are constantly striving to directly implement the innovative insights gained through this commitment in our process technologies and advances in plant development projects – but only after rigorous functional and safety testing.

Our creative, highly-trained development team, always on top of the latest scientific developments, enables us to preserve and extend the technological advantage that we place at your disposal with maximum flexibility and performance.

One of our fundamental principles is to provide our customers with verifiable quality and reliability of the highest standard. Our extensive plant and production experience, our 30 years of successfully serving the chemical industry and our own production facilities embodying the latest pharmaceutical and chemical standards form the ideal basis for this.

We are constantly seeking to further intensify proven forms of working with our business associates, such as production cooperation and the construction of process-technical production equipment at either our facility or the customer’s site in the form of custom-tailored service.

One of our key principles is to work closely with our partners and associates. We carry out project developments on our pilot plants according to our customers’ recipes and in close consultation with them.

Our customers are involved in all decisions at all times, and are the focus of everything we think an do.

We strive to be a fair and open partner for our suppliers at all times.

We are especially committed to preserving and creating jobs in a working climate that emphasizes the pleasure of superior performance.
