2011 INERTIA 4048 FRAP

Description

CHASSIS

The chassis is constructed with W24 x 62 pound I-beam main frame rails. It has a heavy duty impactor

mount with both weld in and bolt on wear liners. Four 24” stroke hydraulic legs with 12volt pump are used

to raise and level the plant for operation. The plant comes equipped with king pin and a heavy duty triple

axle suspension with 11 x 22.5 tires, air brakes, lights, and mud flaps.

FEEDER

The feeder is an Inertia 48” x 16’ vibrating grizzly consisting of heavy channel and plate construction and

has ½” weld in floor and side liners. The feeder uses two Invicta BL 50-57 vibrating motors along with a

slight decline in angle to feed the impactor.

HOPPER

The hopper is removable and is 8’ wide x 17’ long, 7 cubic yards non-heaping. It is constructed of 5/8”

plate and a feedbox with heavy-duty chain curtain to prevent material blow back from impactor.

IMPACTOR

The impactor is an Inertia 4048 HSI (40” diameter x 48” wide) single rotor impact crusher with

sectionalized frame construction of both welded and bolted heavy plate steel. It has replaceable frame

liners of HARDOX-400 material with a wear resistant steel rotor and cast replaceable blow bars. The

impactor has two adjustable breaker plates lined with HARDOX-400 material to control product

graduation and a spring relief system for non-crushable material. It incorporates self-aligning spherical

roller bearings and 4 bolt, split pillow blocks which are protected from dust contamination via a nonrupturable

labyrinth seal. It has four access doors for internal observation, inspection, maintenance, and

repair, and two hydraulic cylinders for opening the impactor hood.

SCREEN

Inertia Spec Maker 6’ x 18’ 2-Deck screen with eleven variable speed (0-3600rpm) electric vibrators with

adjustable slide counterweight force amplitude settings. The screen has five independent screen panels

(6’x6’) with adjustable speed control via a/c inverters located in the electric enclosure.

DELIVERY CONVEYOR

The delivery conveyor is 42” x 46’ under crusher mounted. It has 5 five inch CEMA B impact idlers and

CEMA “B” five inch idlers. The tail pulley is a 12” wing pulley with 2 15/16” pillow block bearings bolted to

18” telescoping take-ups. The head pulley is a 16” crowned motorized drum pulley with vulcanized rubber

lagging that feeds the 6’ x 18’ 2-Deck high frequency screen. The conveyor has a 3ply V-Cleat belt with a

flexco belt splice.

TOP DECK CROSS CONVEYOR

The cross conveyor is 24” x 8’ under chute mounted that transfers material to the closed circuit conveyor.

It has CEMA “B” four inch idlers. The tail pulley is a 10” crowned drum pulley with 1 15/16” bearings

bolted to 9” telescoping take-ups. The head pulley is a 10” crowned drum pulley with 1 15/16” pillow block

bearings. The conveyor is belt driven by a 5hp electric motor and 215 reducer combination. The conveyor

belt is 2 ply 220 with a flexco belt splice. The conveyor is wired to a reverse switch on the electric panel to

remove all non aggregate material from the circuit periodically and discharge it to the ground or a bin.

SECOND DECK CROSS CONVEYOR

The cross conveyor is 24” x 17’ under chute mounted with 9’ fold for transportation. It has CEMA “B” four

inch idlers. The tail pulley is a 10” wing pulley with 1 15/16” pillow block bearings. The head pulley is a 14”

crowned motorized drum pulley with vulcanized rubber lagging bolted to 9” telescoping take-ups. The

conveyor belt is 2 ply 220 with a flexco belt splice.

CLOSED CIRCUIT CONVEYOR

The closed circuit conveyor is 24” x 31’ and takes oversized material from the top deck of the screen and

returns it to the feeder to be reprocessed. It has CEMA “B” four inch idlers. The tail pulley is a 10” wing

pulley with 1 15/16” pillow block bearings bolted to 18” telescoping take-ups. The head pulley is a 14”

crowned motorized drum pulley with vulcanized rubber lagging. The conveyor has a permanent

suspension magnet over a 2 ply 5/8” open cleat belt with a flexco belt splice.

FINES CONVEYOR

The fines conveyor is 48” x 20’ under screen mounted with CEMA “B” five inch idlers. The tail pulley is a

12” wing pulley with 2 15/16” pillow block bearings. The head pulley is a 16” crowned drum pulley with

vulcanized rubber lagging and 2 15/16” pillow block bearings bolted to 18” telescoping take-ups. The

conveyor is belt driven by a 10hp electric motor and 315 reducer combination. The conveyor has a 3ply

330 belt with a flexco belt splice.

POWER/DRIVE

The plant is powered by a 300hp Diesel engine that belt drives the impactor and 125kw 480V-113 amp

generator with 8V belts. The generator supplies power to an on-board electrical switch gear with 100 amp

disconnect and circuit breakers. The circuit breakers are used to supply power to the (2) Invicta vibrating

motors on the feeder, the vibrating motors that power the screen, and conveyor motors. The belt drive

has a fully enclosed guard with two service doors.
