This JCI 8x20 Quarry Screener is a used screener — sometimes referred to as a screen plant — built to separate and sort bulk aggregate, crushed stone, sand, and similar quarried or recycled materials into multiple sized fractions. JCI is a recognised manufacturer of heavy processing and screening equipment serving the aggregate, mining, and quarry industries. This unit was manufactured in 2023 and is located in Montana, USA.
The machine is configured as a portable three-deck horizontal screen plant mounted on a tandem-axle chassis built from heavy-duty wide-flange beam. The running gear includes a heavy-duty 25,000 lb suspension with eight 11R x 22.5 radial tires, along with a full brake package comprising air brakes, an emergency valve, and associated plumbing, plus a light package covering brake lights and directional signals. Four hydraulic jacks powered by a Honda power unit are provided for levelling and stabilisation on site.
The screen itself is driven by a WEG 50 HP, 1,200 RPM electric motor. Material handling off the screen is handled by three conveyors: two 30-inch reversible cross conveyors, each powered by a Dodge No. 3, 7.5 HP motor, fitted with CEMA B idlers and a two-ply belt with a vulcanised splice; and a 60-inch under-screen conveyor with rear discharge, driven by a Dodge No. 4, 15 HP motor, equipped with CEMA C idlers, a two-ply belt, and a Martin wiper vulcanised splice.
All three decks feature roll-away chutes for ease of access and media changes. Each deck's overs chute — top, centre, and bottom — is fabricated from quarter-inch mild steel with welded-in 3/8-inch AR liners and fitted with blending gates. The under-screen hopper is also quarter-inch mild steel, lined with rubber for impact and wear protection. Guarding appropriate to the machine's configuration is included, with the responsibility for compliance with local codes resting with the end user.
Access and operator safety provisions are extensive. A hydraulic folding, diamond-decked catwalk with an access ladder and railing is installed on three sides of the screen. Catwalk access points feature self-closing gates, and an overhead safety tie-off cable is provided.
The electrical package is equally comprehensive. A complete switchgear assembly is housed in a NEMA 4 enclosure and built with Square D NEMA components, including breakers, reversing starters for the cross conveyors, main disconnect, emergency stop, and new-style pushbuttons. The package also includes four additional No. 2 starters for off-plant conveyors rated up to 20 HP each, along with a 100-foot cable lead. A chord holder completes the installation.
