FITZMILL - Mixer - M5A

Mixer FitzMill, model M5A

The D6A FitzMill is ideal for use in continuous or batch production, research, and product development.

Characteristics:

- Quiet operation

- Low dust and low heat

- Wide range of process possibilities

- Easy to clean

- Compact GMP design

- Directly scalable to larger units

- Metered Feed

The metering feed system of the VFS-D6A can greatly enhance the milling process by providing improved product uniformity, and the elimination of operator variables, as well as complete process repeatability.

- Gravity Feed

The FitzMill process chamber is often fed simply by gravity. The S-Pan and VHP D6As, along with the SPV Cabinet Base D6A provide optimal GMP when gravity-fed milling is desired.

- In-Wall Design (VFS - Variable Feed Screw)

The in-wall and on-wall configurations of the VFS-D6A are designed to contain the drive motors in a separate room or technical area. This leaves only a few easily disassembled product contact parts in the process area.

- The RP Cabinet Base M5A incorporates the feed pan and feed throat in one piece. The cabinet base design also integrates the base and controls into a self-contained portable unit.

The VHP D6A featured above employs a large feed pan which is separate from the feed throat. The VHP design is ideal for efficient feeding of large material.

The Product Containment System (PCS) is designed to contain the product inside the process components in order to prevent airborne dust from escaping into the atmosphere. A second objective of this system is to facilitate operation in an inert environment. The method used to contain the product is similar to isolator technology. The process area is kept under a slight negative pressure to ensure that no powder migrates to the outside. The RV D6A PCS with remote electrics (controls not shown) includes a rotary valve feed system.

The PCS uses several primary filters in the machine discharge. These filters are connected to a vacuum system which maintains the proper condition inside the processing chamber. A Fitzpatrick exclusive backpurge cartridge (patented) is utilized to draw process gas in from one filter, in order to backpurge and thereby clean another filter.

Benefits of this new patented system:

- Backpurge cartridge is effective at keeping filters clean without pressurizing process area

- Inert processing with atmosphere monitoring and control is possible with minimal nitrogen consumption (ATEX compliant)

- PCS components are easy to clean and filters are disposable

- Minimal internal surface area with vertical orientation reduces product hang-up and loss

- WIP System available to wet product surfaces after processing
