Dillman silos are built top to bottom with the highest
quality materials and loaded with dependable features.
HANDRAILS, WALKWAYS, AND DECKING
OSHA standard handrail, walkway and checker plate decking are
standard on all Dillman silos. The integral kick plate on the top
deck eliminates spillage down the sides of the silo.
Dillman silos feature OSHA standard handrails,
walkways and decking.
SUPPORTS
Dillman silos feature an all welded support structure. Heavy-duty
steel beam legs with cross bracing offer structural integrity for all
seismic zones. Welded-on legs reduce set-up time.
DUAL CLAM GATES
The dual clam gates on the silo allow for more even and accurate
loading. Includes safety gates which act as a backup to the clam
gates. The safety gates can stop the silo from emptying out on a
truck, preventing a serious accident.

With Dillman silo systems, contractors can achieve
increased production runs, improved truck turnaround
times and an on-hand inventory of different mix designs.
SILO INSULATION
Industrial grade insulation maximizes heat retention. 10” of insulation in the top deck and bottom enclosure, plus 5” running the
entire length of the silo helps you store mix overnight.
A combined five inches of insulation surrounds each
Dillman silo.
HI-LO BIN INDICATORS
Each Dillman silo has a hi-lo bin indicator. A radio frequency rod
extends through the top deck. The design eliminates weak points
and allows service of the rod from the deck.
Hi-lo bin indicator information is transmitted to the control house
so that personnel can track mix level. The high bin level indicator
signal prevents overfilling the silo. The low bin indicator prevents
running the silo completely empty so that when you load from the
batcher you are loading onto material rather than the cone.

REINFORCED CONE
The reinforced cone includes standard electric heat or optional hot
oil heating. The dual clam gate design with insulated safety doors
is supplied for quick and easy load-out. Optional ceramic full
sheet AR or Hi-Tech premium cone liners are available.The Dillman
safety gates come standard with rubber seals, to help eliminate
mix oxidation. Long term storage gates are available for special
applications.
TRUCK SCALES
Heavy-duty all-welded truck scales provide accurate load-out and
quick turnaround times. An optional remote ticketing system is also
available.

Rugged features are solidly constructed to stand up to
years of hard work at an asphalt plant.
EXCLUSIVE CHAIN TENSION INDICATOR
The Dillman exclusive chain tension indicator saves time by letting the operator know when the chain needs to be tightened. This
smaller sized roller is positioned so that as the chain stretches and
sags the roller will start to turn. An operator will know that the
chain needs to be tightened when the roller starts to turn.

DRAG SLAT DRIVE SYSTEM
A powerful drag slat drive system is equipped with a heavy duty
drive chain, segmented sprockets, gear reducer and hydraulically
operated take-up assembly.
DRAG SLAT
The Dillman drag slat at 50” deep and 36.5” wide is the largest in
the industry with a capacity of up to 750 tph (680 metric tons per
hour). Single or double sided stairways are available. The massive
single chain arrangement has A-36 slats. Tri-segmented sprockets
allow for easy maintenance, drastically reducing the time and effort required to change. Wear resistant high chrome flooring with
integral side-wall liners offer significant wear resistance. The high
chrome liners are bolted in for easy replacement. Also includes hydraulically adjusted take-up assemblies, special anti-warp access
doors, an all welded U-box frame and floating and fixed idlers.
HYDRAULICALLY ADJUSTED TAKE-UP
The hydraulically adjusted take-up makes it easier to adjust the
main chain in the drag instead of having to use a jack, porta
power or manually wrenching the adjustment bolts.
Chain tension indicator alerts operator to tighten.

HEAVY-DUTY SINGLE CHAIN
This single chain arrangement for the main drag is equipped with
extra hard rollers, pins and bushings for increased operational
life. Thick all-welded reinforced slats decrease maintenance.

DILLMAN
Dillman drag slat and transfer conveyors are ruggedly
constructed with an all welded U-box frame and
constructed to provide years of trouble-free operation.
TRANSFER CONVEYOR
A horizontal transfer conveyor transfers hot mix from a slat conveyor or bucket elevator to the second and third silos. The transfer
conveyor is equipped with motors and coupled to in-line heavy-duty
reducers. The Dillman transfer conveyor has a strong, all welded,
U-box frame which eliminates cracking potential and improves the
structural integrity. The main frame, which is fabricated entirely
with 3/8” structural steel, consists of unitized sidewalls and sub
floor resulting in an extremely high strength, rigid, frame assembly. The heavy-duty chain arrangement includes reinforced slats.
Segmented sprockets allow for easy maintenance. For strength and
durability, the segmented head sprockets are wear hardened to RC
58/60. High chrome blend liners protect the floors and sidewalls
from wear. A heated floor with insulated heat covers helps prevent
material build-up during start-up and keeps the floor clean. Includes return-run idlers and adjustable take-up assemblies.
EXCLUSIVE BOLT-ON DIVERT GATE
The transfer conveyor includes an exclusive bolt-on divert gate assembly with liners. No more welding gates to shafts inside of the
transfer body. The Dillman divert gate is easily replaced by simply
unbolting the divert gate from the transfer conveyor. This allows
replacing the highest wear area on the transfer conveyor without
welding or torching and without having to also take the transfer
down to the ground. The divert gate ships ready to install and only
takes eight one-inch bolts. The divert gates are lined with wear
resistant plates for added life and have an access door for clean
out. It also allows matching up to different manufacturers easier.
Most divert gates are incorporated into the transfer itself, making it
harder to work on or to add another transfer.
BATCHER
The Dillman batcher features a built-in splitter to protect the leading
edge of the gate and minimize maintenance. The splitter splits material as it drops to help reduce segregation. Square design. Three ton
capacity. Ceramic liners are optional along with AR or Hi-Tech liners.
Optional batcher extensions can increase the batcher capacity to match
an existing set-up or capacity request. With an optional batcher lock,
the hinged flat gates help block air transfer to extend storage time.

With a Dillman silo, you will have an opportunity to configure
your facility with options to better serve your customers and
your community.
OPTIONAL BLUE SMOKE PACKAGES
Blue smoke (hydro-carbon vapor) is generated at mix transfer
points. Blue smoke is actually a haze of petroleum droplets suspended in the air. The blue smoke collection system prevents the
vapor from escaping when asphalt is transferred from the mixer
to the storage silo. The blue smoke system captures the vapor and
uses a fan to transport it back to the drum where it is incinerated
by the burner flame. The result is extremely effective. Virtually no
blue smoke escapes into the air during silo filling.
Blue smoke systems collect hydro-carbon
vapors at mix transfer points.
Load-out tunnels and fiberbed mist collectors can also be supplied
for installations where environmental compliance is a priority.
LOW PROFILE, ELECTRONIC SCALES
The LPSII truck scale is a totally electronic scale with a low profile. It
only needs small foundation pads at each load cell. Weigh sections
have checkered-steel deck plates. The scale is wired in conduit.
When a silo is used without a truck scale, Dillman can provide an
optional weigh batcher.
Load out tunnels capture unwanted vapors.
STAND ALONE CONTROL PANELS
Dillman silos are as well suited to retrofit applications as they are
to new plant installations. The optional stand alone control panel is
designed to integrate into any brand control system.
