KPI-JCI 52 (Plant)

Primary Hopper Belt Feeder:
The primary hopper has a 9 cubic yard capacity with a
top opening of 12’ x 6’-0”. The hopper is constructed of
1/4” thick A-36 steel.

The primary belt feeder is positioned underneath the
primary feed hopper. The belt feeder is powered with a
7.5 hp variable speed electric drive. The feeder has a
belt-width of 30” and is 10’-9” long.

Feed Conveyor:
The feed conveyor transfers material from the feed
hoppers to the pugmill mixing box. It has a heavy duty
channel-type frame, and is powered with a 7.5 hp
electric head end drive. The conveyor is 29’-0” long and
has a belt width of 30”.

Pugmill:
The twin shaft pugmill consists of an enclosed 4’ x 6’
mixing box with AR steel liners. Enclosed in the mixing
box are two heavy-duty 6” XH counter rotating shafts.
These shafts include 40 double tip Ni-hard paddles in
an overlapping spiral arrangement. Paddle tips have an
adjustable wall clearance range of ¾” to 2”.

Power is transferred to the rotating shafts from a 60 hp
electric motor through a v-belt drive. The reducer drives
a single shaft which in turn powers the other shaft
through a set of timing gears that rotate in an oil bath.

It includes an adjustable dam gate, a receiving hood
with spray bar, inspection doors, and a drop out bottom
to provide access for easy clean out.

Chassis:
The pugmill plant’s portable chassis consists of a heavy
duty channel-style frame with a gooseneck and kingpin
located at the feed end of the plant. The chassis utilizes
a walking beam-type tandem axle with dual 11.0 x 22.5
tires (8 total) located at the discharge end. The plant
includes manual landing gear.

Secondary Hopper: (Optional)
The optional secondary hopper has a 6.5 cubic yard
capacity with a 12’ x 6’-0” top opening. The hopper is
constructed of 1/4” thick A-36 steel.

The secondary belt feeder is positioned underneath the
secondary feed hopper. The belt feeder is powered
with a 3 hp variable speed electric drive. The feeder
has a belt-width of 30” and is 10’-9” long.

Water System: (Optional)
The water system includes a 150 gpm pump with 3 hp
variable speed drive, flowmeter, and a valve. The
system can be configured to be adjusted manually or
automatically from the control system.

Asphalt System: (Optional)
The asphalt system includes a 90 gpm pump (powered
by a 10 hp motor), a flowmeter, and a valve. The
system can be configured per customer request to be
adjusted manually or to be automatically proportioned.

Walkway:
The 24” wide walkway gives the operator access to the
pugmill mixing chamber. It consists of an operator’s
platform and a stairway with handrail to provide access
to the platform from the ground.

Automatic Proportioning:
Automatic Proportioning is a feature that utilizes
feedback from a belt scale to automatically adjust the
amount of additives (e.g. water, asphalt, fly ash) that
will be combined with varying amounts of material
being fed to the pugmill mixing box.

Controls:
Controls for the pugmill plant are located on a ground
accessible panel mounted to the side of the plant.
Operators have start/stop capability for the plant as well
as the ability to vary both the speed of the belt feeder
and the rate at which any additives will be blended into
the feed material.
