Dry Granulation Expertise

At Fitzpatrick we are committed to improving the performance and profitability of our customer’s powder processing operations by supplying equipment that incorporates performance, reliability, and longevity.

Recognized as the most trusted name in roller compaction technology and dry granulation equipment for more than 70 years, our customers are supported by world-leading applications and development experts, offering budget-friendly, industrial-strength, high-performance roll compactors for dry granulation processing, with each new generation of machinery incorporating seven decades of knowledge.

Fitzpatrick roller compactors offer a truly scalable equipment growth path. As customers progress from research & development all the way through to full production, results obtained on smaller models are fully transferable to larger systems.

With continual investment in customer-driven innovative solutions to address market needs, Fitzpatrick provides long-term global support via their highly technical customer service and spare parts network.

Acknowledging that each individual process requires specific roll compactor operating features, Fitzpatrick offers two distinct model ranges; the IR (Interchangeable Rolls) Series and the CCS (Contained Compaction Systems) Series.

Both the IR and CCS-Series models utilize the world-class FitzMill™ to mill and granulate the ribbon. Process flexibility is maximized by Fitzpatrick’s unique ability to select either a knife or bar rotor, in addition to having access to an extensive range of perforated screens, including round-hole, rasp, and Conidur™ options.

Adjusting the parameters of roller compaction

1. PRE-COMPRESSION FORCE

The pre-compression force is supplied by the vertical feed screw. This force is necessary for the rolls to draw the material into the nip region and properly compress the material.

2. ROLL DIAMETER

Roll horizontally oriented to assist deaeration and pre-compression.

3. ROLL SPEED

The vertical feed screw deaerates and compresses powder before compaction by the rolls. Co-ordinated control of these components is critical to optimizing densification.

4. ROLL FORCE

The floating roll ensures consistent pressure. A dual hydraulic system ensures ‘floating’ rolls precise force for uniform compacts. Precise parallel roll forces are achieved using linear bearings.

5. ROLL GAP

Roll gap monitored via a linear variable differential transducer. Automatic gap control is achieved through operator interface. No external adjustments are required.

 

6. ROLL SURFACE PROFILE

Roll surface selection is product-dependent. Establishes friction between product and roll surface.

 

7. MILLING ROTOR DESIGN

Two milling alternatives:

  • Knife rotor for ‘in air’ size reduction. Typically used for harder compacts.

  • Bar rotor for ‘crushing’ reduction. Used at low speeds for softer compacts and to reduce fines.
