The Empire Series Rectangle has a multiple compartment cement silo in lieu of round silos.The Empire Series Rectangle's advantage is in the silo design. The Empire Series Rectangle plant has a silo from 200 tons to 375 tons with two to six compartments. This design eliminates screw conveyors, reduces the number of piers and footers required, increases yard space and increases storage. It also keeps a relatively low overall height. This plant can easily be enclosed and can produce concrete around 200 yards per hour.

Standard Equipment:
• Multiple compartment silo:  with 4” thick double wall partition with penetration check plug in wall. (4” wall will reduce total capacity of silo approx. 4%)
• One safety pressure-relief valve with cover mounted on top of each compartment.
• One 4” diameter fill line with camlock coupling on each compartment.
• Aeration diffusers (rectangle) in each cone with electric solenoid and filter regulator.
• Aeration blower strongly recommended.
• Outside ladder and safety cage, with toe board and pipe handrails around top of silo.
• Expanded metal service platform around batcher.
• Inspection hatch on top of each compartment. 
• 10” butterfly valve on each cone, with actuator and electric solenoids.
• Manual emergency slide gate on each cone of silo.
• Hi & low material level indicators in each compartment with lighted signals in control box.
• SOS-1020:  Silo cartridge vent, one (1) on each compartment

Easy erecting, modular type stationary plant.  Heavy duty H-beam columns support aggregate batcher and bins.  1/4" steel on sloping sides of batcher and bins.  All seams are welded inside and out.  All Stephens gates are permanently lubricated with six (6) 3/4" teeth per gate.  Gates bolt to bins and batcher for easy replacement and maintenance.

We can custom-build a plant to your size requirements or to hit existing footers and piers.

Standard Equipment:

Cement Batcher:
• 14YD cement batcher 140-Cu. Ft. with 10,000 LB lever system, one “s” type load cell (150’ cable) with 0-10 VDC digital readout, with inching gate on batcher, inspection hatch on top of batcher.
• 10” butterfly valve.
• Actuator with electric solenoid and flo-restrictors mounted in solenoid.
• Two aeration pads in cone of batcher with solenoid controls and filter regulator
• Turbine type air vibrator with electric solenoid.
• Hanger lugs for hanging test weights and safety chains to secure batcher

Batching Silo:
• 374 thru 606 BBL silo constructed of 3/16” steel plate with ¼” domed top.  837 thru 1,069 BBL similar with ¼” metal in 1st band. (All two compartment silos have 1/4” in each  band).
• Safety pressure relief valves.
• 4” diameter fill lines, inside silo per compartment.
• 8 aeration pads in each cone and filter regulator per compartment.
• Outside ladder and safety cage.
• Expanded metal service platform around batcher.
• Inspection hatches on top of silo.
• 10” butterfly valves on silo, with actuators and electric solenoid per compartment
• SOS-1020 silo cartridge vent per compartment. 
• Hi & low-level indicators per compartment.
• Manual emergency slide gate per compartment.
• Silo support structure constructed of steel “structural” beams 374-606 BBL = W8 x 31#, 837 BBL = W8 x 48# 1069BBL=w10x49 Based on 10c mph. wind/load. Consult factory for other models.

Overhead Aggregate Bin Section:
• Two clam gates on each compartment (when possible). Each gear type gate has six (6) ¾” teeth per gear. Each gate has permanently lubricated bronze bushings on each gear.
• Each gate has a 5” diameter air cylinder  with electric solenoid.
• Sloping sides of gate section fabricated of ¼” plate with remainder 3/16” vertical sides.
• Heap plates.
• Support structure constructed of steel “structural” beams.
• ¼” abrasive resistant steel (400 Brinnell) welded immediately above each gate (approximately 12” tall).
• Aggregate bins are rated at heaped capacity based on 100 lbs cu. ft.

Aggregate Batcher:
• 12 Yard capacity with 40,000 lb scale lever system.  One “s” type load cell (150’ of cable) with 0-10 VDC digital readout.
• 580 Cu. Ft. capacity at water level.
• Sloping sides fabricated of ¼” plate, 3/16” remainder.
• Two discharge openings in batcher with one (1) extra long double acting clamshell gate, under both openings.  
• Gear type gate with six (6) ¾” teeth per gear.  Gate has permanently lubricated bronze bushing.  Gate will be actuated by two 5” air cylinders, with flo-restricators mounted in solenoid, (NOTE:  If conveyor comes out the “wide side” the batcher will have only one discharge opening, one cylinder, and solenoid for gate.)
• Two turbine air vibrators.
• Filter, regulator, lubricator unit for solenoids and air cylinders.
• Hanger lugs for hanging test weights.

The stationary Stallion aggregate section is constructed of 1/4" steel on sloping sides and 3/16” steel on vertical. The aggregate batcher is 12 yd. and the plant is standard with a 30” transfer conveyor. 36” belt and A/R or poly liners are available. The stallion series aggregate bins can go up to 200 ton max. For larger size aggregate bins please consider the Empire Series Heavy Duty Plant. All aggregate gates will have permanently lubricated gear gates with six (6) 3/4” gear teeth. All cylinders are 5” x 8” with coated shafts for extra protection.

The round Stallion Batching silo has a 14yd cement batcher and the silo can range between 374 BBL to 1069 BBL. We can do single or double compartments. Each Silo can be customized with different cement silo dust collectors, ladders, cages, and platforms. All silos will have a 3/6” cone, 1/4” domed top. Larger silos will have bottom rings constructed from 1/4” steel and all two compartment silos will have all the rings fabricated from 1/4” steel.
