Page 3: Introduction
INTRODUCTION The MATSYS Fluidized Fill Shoe System (FFS) is a powder delivery system designed for consistent, fast and uniform filling of small die cavities. It can be used on a wide variety of particulate materials. The FFS system includes a fluidized fill shoe and a control cabinet. -

1. Transport tube. The transport tube provides the connection between the particulate material supply hose and the delivery chute. It begins the process of conditioning the particulate material to a fluidized or loose state and conveys the particulate material to the delivery chute. 2. -
Page 5: Fluidization Principle
FFS BASIC PRINCIPLE Powder flows like a fluid when supported by a column of gas. The result is a reduction in the effects of head pressure, clumping and surge, both of which are common in gravity fed systems. The fluidized fill shoe creates a low pressure gas bearing below the powder inside the shoe to reduce the friction along the powder path to the fill point. -

SYSTEM SETUP AND INSTALLATION 1. Gas Supply The most optimal method of fluidizing is to use an inert gas such as Argon, alternatively compressed air can be used when properly treated, dried and filtered. When a compressed air source is used to supply air pressure to the fluidized fill shoe, the gas control supply pressure should be between 30 and 60 psi. -

Figure 2. It is recommended that the customer air supply line be plumbed as shown with a vertical inlet pipe to separator, trap, and drain valve. 2. Fluidizer Control Fluidization ‘ON’ / ‘OFF’ control is used to optimize the filling process. To use fluidization ‘ON’... -

Mounting the Shoe on the Press Mounting the fluidized fill shoe on the press is a simple procedure. However, it is important to strictly observe the following mounting requirements: 1. -
Page 9: Connection To Control Cabinet
The fluidized fill shoe should follow a reproducible path for each stroke. This can be observed by sprinkling some excess powder around the die opening and observing the powder wipe trail during each stroke of the shoe. If there is excessive lateral or axial play in the fluidized fill shoe retraction mechanism, the shoe will wander as it moves in and out. -

6. Verify that you get approximately the same flow values as those printed in the “Fluidizer Gas Calibration Chart”. If you experience problems obtaining similar values to those given in the chart, contact MATSYS before proceeding. Otherwise you are ready to operate the fluidized fill shoe. -

7. Operation For first time use you should adjust the gas pressure regulator and flow meters as follows: 1. Connect powder hose from hopper to transport tube. 2. With particulate material in the fluidized fill shoe, set the gas pressure regulator to a minimum of 0.25 psi. - Page 12 If cleaning the fluidizer porous plate in the described manner does not remove the contamination, the plate may need to be repaired or replaced. In this case it is recommended that the fill shoe be returned to MATSYS for service.

APPENDIX B FFS OPERATION Once the fluidized fill shoe is mounted on the press and proper operation is verified, it is important to periodically check the fluidized fill shoe performance during extended production runs. The following chart summarizes the fluidized fill shoe operational readiness checks along with the recommended time periods between checks. - Page 16 FLUIDIZER GAS FLOW SET POINT – The fluidizer gas flow Before each run settings should be checked to verify that they are at the correct values. See factory calibration values below. WEAR PLATE The wear plate around the chute Before each run opening should lay flat along the press table with no gaps.
