We write the mass balance. We cut the steel. We sign the first-ore sheet.
Ridgecast designs and builds crushing, screening, and conveying plants for hard-rock mines and quarries. One office, one drawing set, one name on the handover — from ROM intake to the stockpile belt.

01 / The works
One office, pit face to stockpile
Most plant failures are paper failures — a balance that never closed, a liner nobody stocked. Ridgecast keeps the whole chain in one office so the numbers survive contact with rock.
01
Design from a sample, not a brochure
Circuits are sized from your UCS, abrasion index, and a 200 kg PSD — never from a catalogue t/h. Circuit design →
02
Machines built to a frozen drawing
First article ships with a liner set and the dimension sheet. Every repeat part goes out against the same drawing number. The machines →
03
Handover is a sheet, not a handshake
CSS, stroke, and amps at the agreed t/h, signed on the pad at first ore. That sheet drives your wear forecast for the next six months. Commissioning →
02 / Machine catalog
Four machines, one circuit logic
Each machine is sized to sit in a Ridgecast circuit — gape to CSS to deck cut to belt width. They also sell standalone, against the same drawings.
Secondary crushing
RC-C900 Cone Crusher
Secondary cone, 900 mm head, closed circuit with the RC-S2460 screen.
220–310 t/h at CSS 22–32 mm

Screening
RC-S2460 Triple-Deck Screen
2.4 × 6.0 m triple-deck screen, modules for wire or PU.
Up to 400 t/h feed · depending on cut

Conveying
RC-B1200 Overland Conveyor
1 200 mm overland belt in modules, transfer tower included.

Three programmes, delivered as one circuit
Ridgecast sells circuits, not crates. Each programme ships as a mass balance, a steel list, the machines, and the first wear set — with civil and HV on the mine's side of the fence, in writing.
OP
Open-Pit Crushing Circuit
Jaw, cone, screen, and overland belt as one circuit, with mass balance and first wear set. 400 t/h nominal; 16-week first circuit
UG
Underground Transfer Plant
Low-headroom secondary plant for decline and shaft-fed ore. 180 t/h in 4.2 m headroom
04 / Services
Paper, pads, and parts
Three services cover the life of a Ridgecast plant: the balance before the steel, the crew at first ore, and the liners for as long as the pit pushes back.
Before the steel
Circuit Design and Mass Balance
Mass balance, steel list, and wear forecast from a rock sample and a product spec.

Wear Parts and Relines

Where the plants go, what the stages are
Line categories
Open pit — Primary and secondary circuits for surface mines: jaw, cone, screen, and overland conveyors sized to the haul cycle.Underground — Low-headroom crushers and transfer conveyors for decline and shaft-fed plants — designed to the mine's envelope, not the other way around.Aggregate — Quarry plants for roadstone and concrete sand, with a published wear-part cycle. Built for a single shift and a Saturday wash-down.
Process stages
Primary crushing — ROM intake: jaw or gyratory, grizzly, and the first belt.Secondary crushing — Cone or HSI reduction to a closed-circuit product.Screening — Multi-deck screens and wash modules that hold the spec.Conveying — Plant belts, overland lines, and transfer towers.
