Precision-Manufactured Roller Compactor Machines

Pharma High Containment Compactors



Provides optimized particle size and density characteristics for granulated material to reduce segregation while enhancing flow and compressibility in downstream processing steps for oral solid dosage manufacturing




Sanitary, Food and Industrial Roll Compactors


Designed to similar operational standards of the CCS Chilsonator line, but with a more modular configuration to improve application flexibility, for applications requiring a reduced level of containment.


Designed for high-capacity, heavy-duty compacting and briquetting. Widely used in chemical processing, food manufacturing and other industrial applications.

Laboratory Roll Compactor



The new CCS320 is ideal for laboratory roll compaction, with capacities of up to 50 kgs/hr, making it the perfect roller compactor for R&D or small-scale production.




Discover the Technology Powering Our Roll Compaction Equipment

Our roller compactors provide the most important characteristics sought by manufacturers in a variety of exacting industries; ranging from food to plastic, to chemicals and pharmaceuticals. Whether you’re interested in high-volume, heavy-duty compacting and briquetting, for applications ranging from chemicals production to food manufacturing — or you’re focused on the strict need for effective containment required for safe, efficient processing of pharmaceuticals — The Fitzpatrick Company has a roller compactor to meet your unique process needs. 

For instantaneous, continuous compacting of fine pharmaceutical powders, we’re proud to offer the Chilsonator™ Roll Compaction System. Recognized throughout the world as the leader in dry granulation compaction equipment, the ingenious design of these machines ensures best-in-class containment, including optional wash-in-place (WIP) capability, and fewer parts, to minimize down time and facilitate cleaning, maintenance and changeovers. Of course, our roller compactors for pharmaceuticals are cGMP compliant.

Maximized containment means operators are at decreased risk of occupational exposure to active pharmaceutical ingredients. It also ensures there’s less chance that raw materials will be exposed to the environment, minimizing potential product contamination, and reducing product waste. Even better, our Product Containment System (PCS) may be further enhanced through the addition of the optional N2 inerting system.

The Chilsonator™ series also offers secure, fully automated controls, and our scalable equipment parameters facilitate rapid process development and reliable scalability. Of course, scalability is an important factor when it comes time to move from the development phase to full production runs.

Principles of Roll Compaction

The basic concept of roll compation is to force fine powders between two counter rotating rolls. As the volume decreases through the region of maximum pressure, the material is formed into a solid
compact or sheet. Some of the factors controlling the compaction process are roll surface, diameter, peripheral speed, separating force or pressure capabilities, feed screw design and basic compaction characteristics of the material being processed.

As the rolls turn towards each other, the material in the slip region is moving downward at a rate less than the surface speed of the rolls. In the nip region, the material is caught or trapped by the rolls and is moving at the same speed as the roll surface. This forces the material through the region of maximum pressure, which is on a line between the centers of the two rolls. Maximum density will usually approach, but not reach the theoretical density of the material.
