Roll Compactors in Detail
Please select the numbers in the diagram below to read more about the components of the Fitzpatrick Roll Compactor.
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.
Roll horizontally oriented to assist deaeration and pre-compression.
The vertical feed screw deaerates and compresses powder before compaction by the rolls. Co-ordinated control of these components is critical to optimizing densification.
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.
Roll gap monitored via a linear variable differential transducer. Automatic gap control is achieved through operator interface. No external adjustments are required.
Roll surface selection is product-dependent. Establishes friction between product and roll surface.
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.

CCS-Series
The CCS-Series provides a truly scalable equipment growth path. Offering high containment, progress from R&D to full-scale, high-capacity production-scale models, with fully transferrable results at each stage.
LCS Model
Ideal for R&D or smallest volume production. The Lab Compaction System with a high-precision, twin feed screw system, delivers high-performance dry granulation with production-scale capabilities.
CCS220
Ideal for R&D proof of concept research
The CCS220 model is a compact, mobile unit which is easily movable. With consistently sized roll diameter across the CCS-Series of machines, scale-up to production size equipment is easily achieved.
Lab and pilot conversion kits allow for reciprocal conversion between the CCS220 and CCS320 models, dependent on pressure and capacity.
Suitable for mounting in-wall, free-standing, portable or in an isolator/flow booth.

CCS320
Ideal for small volume/pilot-scale production
Designed with three rolls, the CCS320 model is a compact, mobile unit which is easily movable. With consistently sized roll diameter across the CCS-Series of machines, scale-up to production size equipment is easily achieved.
Lab/pilot conversion kits allow for reciprocal conversion between the CCS320 and CCS220 models (pressure/capacity dependent).
Suitable for mounting in-wall, free-standing, portable or in an isolator/flow booth.

CCS520
Suitable for mid-sized production-scale capacities
The CCS520 model is available as a free-standing or in-wall installation. In-wall installations minimize clean room space requirements and allow for internal maintenance access without the need for PPE.
The optional Product Containment System (PCS) minimizes operator exposure to active ingredients for additional security and prevents product loss or contamination.
Simple straightforward design with clean-in-place (CIP)/wash-in-place (WIP) capability.

CCS720
Designed for large production-scale capacities
The CCS720 model is available as a free-standing or in-wall installation. In-wall installations minimize clean room space requirements and allow for internal maintenance access without the need for PPE.
The optional Product Containment System (PCS) minimizes operator exposure to active ingredients for additional security and prevents product loss or contamination.
Simple straightforward design with clean-in-place (CIP)/wash-in-place (WIP) capability.

CCS1025
The maximum volume capacity model in the CCS-Series
This is the largest capacity of the CCS range and comes as a free-standing or in-wall installation. The in-wall version provides rear access to the technical area, improving ease of use and eliminating the need for PPE.
The optional Product Containment System (PCS) enhances safety by reducing operator exposure and protecting product integrity.
A sheet-breaker is also available to increase the efficiency when milling broader ribbons.

Ideal for proof-of-concept work or trial batch production
The LCS is a low-volume benchtop system that processes powders with the same pressure as larger production-scale roller compactors. With a choice of roll surfaces, this machine is manufactured with a high-precision, twin feed screw system which ensures your development projects can progress from the lab to production with confidence.
Complete disassembly of all contact parts enables thorough cleaning that is quick and easy to carry out.
Optional touchpad control of all independent feed and compaction variables as well as cGMP software.
