Ore Processing and Haulage Plant: walk the fixed plant
Walk the full fixed plant from weighbridge to rail loadout: dumping, crushing, conveying, stockpiles, grinding, separation, tailings and site services.
About
Walk the fixed plant between a mine and a railhead, from the gate weighbridge in the south to the tailings pond in the north.
What is placed: 51 of the 56 designs as about 200 placements on an 80 by 78 m yard. Receiving (dump pocket, grizzly, jaw crusher, apron feeder, rock breaker), the crushing loop (cone crusher, vibrating screen, sample tower, dust units), a full conveying kit (straight, incline and curve modules, level and rising gallery bridges, two transfer towers, head and tail stations, walkways, trippers, three radial stackers and the 44 m feed flight), stockpiles with a reclaim tunnel, grinding and separation (SAG mill, ball mill, cyclone cluster, thickener, flotation bank, filter press, reagent farm), loadout (silo cluster, rail and truck bins, weighbridge), tailings and water (berms, decant tower, pond edges, spillway, pump house, pipelines, process tank), and site services (assay lab, MCC building, workshop, lamp room, change house, core shed with stocked tray racks, fuel island, site office).
What moves: nothing. The members snapshot lists zero animation clips across all 56 members, so every placement uses the default proximity setting and the plant reads as a working but paused site. No animate flags are set anywhere.
What is static and why: everything is static because the pack ships no clips. The caption points carry the process story instead, one per station along the walk from gate to pond.
What is not placed and why: the five composed environment scenes (plant overview, milling and separation area, stacker stockpile and reclaim tunnel, tailings storage with water plant and services, belt connector cases). Each is a precomposed multi building diorama tens of metres across, so placing even one would swallow the walkable plot. Their member buildings all appear here as individual models.
Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
Points of interest
Gate and weighbridge
Every load crosses the weighbridge by the site office before it tips. Start here, then walk north past the fuel island to the dump pocket.
Weighbridge and kiosk (Ore Processing and Haulage Plant)Truck dumping
Haul trucks tip into the dump pocket while the pedestal rock breaker handles oversize. The grizzly feeder and apron feeder meter rock to the jaw crusher.
Truck dump pocket (Ore Processing and Haulage Plant)Primary crushing
The jaw crusher station breaks run of mine rock, with the cone crusher and vibrating screen closing the loop. Dust units sit along the whole line.
Primary jaw crusher station (Ore Processing and Haulage Plant)Conveyor spine
Straight, incline and curve modules carry crushed ore east under gallery bridges, through the tall transfer tower to the stockpile trippers.
Conveyor transfer tower (Ore Processing and Haulage Plant)Stockpiles and reclaim
Radial stackers build the coarse cone and the product windrow. The reclaim tunnel draws ore back out to feed the grinding mills.
Reclaim tunnel entrance (Ore Processing and Haulage Plant)Grinding
The SAG mill and ball mill grind ore to slurry, with the cyclone cluster sorting fines. The long feed flight climbs in from the stockpile side.
Semi-autogenous grinding mill (Ore Processing and Haulage Plant)Separation
Flotation banks, the thickener, the filter press and the reagent farm turn slurry into concentrate. The sample tower checks grades along the way.
Flotation cell bank (Ore Processing and Haulage Plant)Rail loadout
Concentrate leaves through the silo cluster and the rail loadout bin, with a truck bin beside it for road haulage to the railhead.
Rail loadout bin with clam gate (Ore Processing and Haulage Plant)Tailings and water
Berms ring the tailings pond where the decant tower returns water. The pump house, pipelines, process tank and spillway close the water loop.
