Radial Stacker Manufacturer in India
Radial Stacker Manufacturer in India
Neo Conveyors is a leading Radial Stacker Manufacturer in India, offering custom-engineered radial stacking conveyors for bulk material stockpiling. Our radial stackers reduce material segregation, equipment movement, and operating costs — building large stockpiles efficiently across cement, mining, aggregate, power, fertilizer, and biomass industries.
What is a Radial Stacker Conveyor?
A Radial Stacker is a specialised belt conveyor mounted on a pivoting mechanism that rotates around a central point to create large stockpiles of bulk materials — distributing material evenly and maximising storage capacity without requiring multiple fixed conveyors.
How a radial stacker differs from a fixed conveyor
A conventional fixed conveyor always discharges material at the same point — requiring the conveyor to be repositioned by machinery whenever one area fills, or requiring multiple conveyors to cover a stockyard. A radial stacker eliminates both problems: the conveyor boom swings in an arc (typically 180°) around a fixed central pivot, continuously distributing material across a fan-shaped area without any repositioning of the machine itself.
The pivot point is the only fixed element — the rest of the conveyor rides on steel-tyred wheels or rail-mounted carriages, swinging smoothly through the arc under manual or motorised control.
Why stockpile capacity increases dramatically
A fixed conveyor builds a cone-shaped stockpile directly below its discharge point — limited in radius by the material's angle of repose. A radial stacker builds a fan-shaped stockpile across the full arc of its travel — dramatically increasing the volume stored per unit of footprint. A 30 m radial stacker swinging 180° can create a stockpile equivalent to what would require 5–6 fixed conveyors at different positions.
This combination of larger stockpile volume, reduced equipment movement, and continuous operation makes the radial stacker the most efficient stockpiling system for bulk material handling yards.
How a Radial Stacker Works
Four elements work together to create the radial stacker's unique stockpiling capability — the fixed pivot, the swinging conveyor boom, the radial travel mechanism, and the infeed arrangement.
Bulk material is fed onto the conveyor belt at the tail (infeed) end — near the fixed pivot point — via a feed hopper, chute, or transfer from another conveyor. The infeed arrangement is flexible because the tail end's position changes only slightly as the boom swings.
The drive motor at the head end pulls the belt, carrying material from the tail end along the full length of the inclined conveyor boom. Trough idlers along the boom contain material during travel. Belt inclination is typically 18–22° for most bulk materials.
Material discharges over the head pulley at the elevated discharge end, falling into the growing stockpile below. As the stockpile builds directly beneath the head, the boom is incrementally swung through the arc — moving the discharge point to an unfilled area.
The conveyor carriage swings continuously or incrementally through its 180° arc — driven by a motorised travel mechanism or repositioned manually with a winch. The fan-shaped stockpile fills progressively across the full arc without any repositioning of the feed equipment.
Benefits of Radial Stackers
Five operational and engineering advantages that make the radial stacker the most efficient and cost-effective stockpiling system for bulk material handling yards.
Increased Stockpile Capacity
A 30 m radial stacker sweeping 180° creates a fan-shaped stockpile up to 5–6× larger than a fixed conveyor of the same length. More material stored per unit of yard area — reducing the land requirement for stockpile operations significantly.
Reduced Material Segregation
By continuously building the stockpile in thin, overlapping layers across the arc, the radial stacker deposits fine and coarse fractions together — reducing the size segregation that occurs when material is always dumped at the same point.
Lower Equipment Operating Costs
One radial stacker replaces 5–6 fixed conveyors, multiple transfer points, and the loaders or dozers that would otherwise be needed to reposition fixed equipment. Fewer machines, fewer operators, lower maintenance, lower energy cost per tonne stockpiled.
Efficient Bulk Material Handling
Continuous operation without stopping to reposition — the conveyor keeps running as the arc sweeps, maintaining full rated TPH throughout the stockpiling cycle. No idle time between repositioning moves that fixed systems require.
Improved Yard Management
A single radial stacker with one operator can manage the entire stockyard — positioning the boom by motorised swing control to fill different areas of the yard without additional machinery. Simplified operation, simplified maintenance.
Heavy-Duty Construction for 24×7 Operation
Fabricated in MS with heavy-duty channel frame, sealed pivot bearing, steel-tyred travel wheels, rubber lagged drive pulley, and EP belt — designed for continuous 24×7 operation in outdoor plant environments with minimal maintenance.
Industries Using Radial Stacker Conveyors
Radial stackers are deployed wherever large volumes of dry bulk material must be stockpiled efficiently — across India's cement, mining, power, agriculture, and port sectors.
Cement Plants
Limestone, sand, fly ash, and slag stockpiling at raw material storage yards. Clinker stockpiling before cement mill. Continuous 24×7 operation at 100–500 TPH.
Mining & Quarry Operations
Run-of-mine ore, coal, crushed stone, and mineral stockpiling at mine surface. Large-capacity radial stackers building multi-tier stockpiles at crusher and screening plant discharge.
Aggregate & Stone Crusher Plants
Multiple product fractions (10 mm, 20 mm, 40 mm, dust) stockpiled at screening plant discharge. One radial stacker per fraction — or multi-position stacker for smaller plants.
Power Generation Facilities
Coal and pet coke stockpiling at thermal power plant fuel yards. Radial stacker builds the coal stockpile from wagon tippler discharge — typically at 300–500 TPH across large outdoor yards.
Fertilizer Industry
Urea, DAP, MOP, and granulated fertilizer stockpiling at bulk storage facilities before bagging. Enclosed stockyard options for hygroscopic fertilizer materials that must be protected from moisture.
Biomass & Alternative Fuel Plants
Rice husk, wood chips, bagasse, and biomass pellet stockpiling at power plant fuel yards. 35° trough radial stackers for fine, light biomass materials — preventing spillage over lower-angle wings.
Ports & Terminals
Bulk cargo stockpiling from ship unloading lines at port material handling terminals. High-capacity radial stackers at 300–500 TPH building large stockpiles in limited port yard area.
Warehouses & Bulk Storage
Indoor radial stackers for grain silos, fertilizer warehouses, and bulk material covered storage — compact boom designs for indoor operation with reduced floor clearance.

Recent Radial Stacker Installations
Four recent radial stacker projects with full engineering parameters — demonstrating real-world capacity, boom length, and stockpile results achieved at customer plants.
Cement plant needed to build large limestone stockpile from crusher conveyor discharge — 180 TPH, continuous 3-shift operation. Fixed conveyor was creating a single cone stockpile requiring regular dozer intervention to spread material. 30 m radial stacker with motorised travel installed — swinging automatically through 180° arc.
Biomass power plant needed to stockpile mixed rice husk and wood chips (bulk density 0.15–0.25 t/m³) from multiple feed conveyors. Light, fine materials required 35° trough to prevent spillage. Outdoor installation in UP/Haryana required galvanised frame. 25 m radial stacker with manual winch travel installed.
Stone crusher plant needed to stockpile 20 mm and 40 mm crushed aggregate from two screens. Space-constrained site could not accommodate separate fixed conveyors for each fraction. Two 20 m radial stackers — one per product fraction — installed on opposite sides of the crusher screening plant, each building an independent stockpile.
Fertilizer blending plant needed to build urea granule stockpile inside a covered warehouse — space constrained by roof structure. Indoor radial stacker with reduced boom height profile designed to fit within 8 m roof clearance. Full MS enclosed casing on boom to prevent moisture absorption during conveying. Manual winch repositioning.
