DIGI-FEEDTM I

Digital Cold Feed Materials Blending System

for Asphalt Plants

DFeed1.jpg (27518 bytes)

DIGI-FEEDTM I is designed for precise cold feed bin aggregate delivery control on continuous mix or drum mix plants that have scales on their virgin aggregate conveyor belt.

DIGI-FEEDTM I controls start/stop and ratio blending of up to six cold feed bins to exacting mix formulas. It should also be considered for batch plants running screenless.

DIGI-FEEDTM I features a digital output single electronic control board that requires no field adjustment. This provides easy troubleshooting or replacement. Fully digital SCR feeder motor speed controls, that also require no field adjustment, provide accuracy of one RPM, at any speed, for exact aggregate blending.

DIGI-FEEDTM I provides easy calibration in one minute or less per bin. The operator may store two easily entered aggregate mix designs enabling "on the fly" mix changes without interruption of plant operation. The unique alarm system warns if a feeder is over maximum, out of tolerance, or has a feed loss (and provides automatic shutdown, if required).

DIGI-FEEDTM I includes operator panel pre-wired to the control electronics, digital DC motor speed controls and digital motor tachometers.

with manual backup

EZ-FEEDTM is a computerized aggregate cold feed control system for Drum, Batch or Continuous Mix asphalt plants. It can simultaneously control up to 12 cold feed bins and the software is specifically designed to perform "on the fly" sequential aggregate mix formula and/or TPH changes, including coordinated starts and stops. The system can handle up to 500 raw materials and 500 mix formulas (virtually unlimited numbers optionally). A menu-driven method is used to access data and to provide maximum flexibility in data management by pressing either a single letter, number, or using arrow keys to move to the desired topic. Both plant and system parameters can be changed using this menu system. The EZ-FEEDTM can be supplied as a stand alone unit or integral part of EZ-BLENDTM

or multi-tasked in the same computer with EZ-BATCHERTM.

The standard features include monitor, computer, keyboard, disk drives, computer interface printed circuit board with 12’ shld. cable, plant interface NEMA box with buffer printed circuit board and

rails, 4 bin control printed circuit board, and 4 bin control software. A digital tach for each feeder controlled is required, but not supplied.
