Minor
feed systems include: Surge hopper, Transition, Vibrator, Feeder tray,
Weigh hopper and related PLC controls. The feeder and weigh hopper are
sized to provide desired feed rate and weighing accuracy required.
Minor ingredient stand can contain up to eight individual ingredients.
Minor module is built to be completely wired and plumbed and tested
prior to shipment. Entire system is designed to fit standard shipping
containers for oversea's shipments.
Surge
hoppers can be build to different capacities. Typically the sizes
are 5, 10, and 15 cubic foot. Hoppers are available in
carbon steel or 304 stainless steel. Each hopper includes hinged cover
lid with handle and gas springs to assist in opening and closing. Most
of our systems have included (4) - 5 cubic foot hoppers, (2) - 10 cubic
foot hoppers and (2) 15 cubic foot hoppers. We can customize the hopper
capacites as needed.
This
end view of the minor system shows (8) ingredient systems and the weigh
hoppers range from 1KG to 30KG capacities. All of the weigh hoppers are
dumped on the belt conveyor that runs under the row of weigh hoppers.
The hoppers discharge is controlled by pneumatic cylinders with flow
controls. Conveyor belt includes skirts and speed sensor to monitor
operation before hoppers discharge. The belt conveyors discharge the
products into the "Re-Weigh" hopper which provides a check weight of
all of the ingredients to be assured all have discharged.
Screw
feed systems can feed such ingredients as TIO2 into the batch. Screw
feed system includes screw properly sized to deliver the amount at the
desired feed rate, hold hopper, vibrator, high and low level lights to
alert operator when refill is needed, control panel for pneumatic and
electrical connections to PLC. Hopper includes removable lid.
Weighing
system includes load cells, summing junction box, digital weight
indicator or direct PLC scale card, and communication module to PLC.
Scales are all NTEP approved and are fully tested with certified test
weights. Automatic calibration cycles are available as option as well
as automatic test weigh application to verify scale accuracy at the
touch of a button.
PLC
control panel utilizes the Allen Bradley PLC family and can be either
the SLC or Control Logix package. All controls are pre-wired and tested
at the factory. All systems include remote programming capabilities.
Tumblers
are provided to mix all of the pre-weighed ingredients. Variable speed
control provided to control the speed and duration of the mixing.
Special design discharge gate used to load and unload the tumbler. Gate
is pneumatically actuated with locks and sensors for monitoring.
Hartman
Scale will design, build and program for any number of alloys needed
and can include all support equipment such as powder (tio2) feeder,
tumblers, and or bucket elevators to move product to customer press. If you are building electrodes or briquettes we can help with the batching and mixing process.
