A well-designed radial stacker conveyor brings efficiency and flexibility to aggregate stacking while reducing material handling costs. As a professional bulk material handling solution provider, ZOOMRY supplies a complete range of radial stackers and portable stacking conveyors for mining and quarry applications. This guide explores why radial stackers are worth the investment.

Why Choose a Radial Stacker?

Radial stacker conveyors solve a common stacking challenge: stacking aggregates higher maximizes space utilization, but taller stacks make efficient and safe operation more difficult. Radial stacker conveyors lift aggregates to discharge points up to 40 feet above the stack while rotating to store material in a higher and wider arc — allowing more material storage without repositioning equipment. This delivers:

• Higher safety — reduced equipment movement and operator interaction
• Lower material handling costs — eliminates wheel loader re-handling
• Reduced fuel and labor overheads
• Reduced dust and material waste
• Increased profitability through operational efficiency

With slopes of up to 20° and lengths of 150 feet or more, radial stackers move materials at speeds up to 1,200 TPH and handle a variety of aggregates: quarry stone, sand and gravel, mining overburden, frac sand, salt, and fly ash. ZOOMRY's wheeled radial stackers handle up to 3,500 m³/h with stacking heights reaching 20 meters.

Radial Stacker Design Options

Design Type	Description	ZOOMRY Solution
Telescopic	Discharge head moves further from the loading point — increasing capacity by building larger stockpiles without repositioning.	Telescopic Radial Stacker
Portable	Lightweight construction for smaller units moved between temporary locations — road camps, wellhead supply points.	Portable Radial Stacker
Tracked	Crawler-mounted for soft ground mobility — self-propelled, no towing required.	Tracked Radial Stacker

Key Components of a Radial Stacker System

Component	Function
Assembly Truss	Frame that supports the conveyor and material load — heavy-duty steel construction.
Radial Landing Gear	Movable component allowing the stacker to rotate — enables radial stockpile formation.
Conveyor Belt	Designed according to material characteristics — width, cover grade, and carcass type matched to application.
Head (Discharge Point)	End of conveyor where material discharges onto the stockpile.
Tail (Loading Point)	Point where material is loaded onto the conveyor — typically from a hopper feeder or upstream conveyor.
Drive Unit	motor and reducer mounted in the head, connected to the discharge pulley.

Cost Drivers for Radial Stacker Conveyors

Radial stacker conveyors are customized machines — overall cost is determined by several key factors:

• TPH (tonnage per hour): Determines belt width (24-60 inches) and speed required.
• Elevation: Maximum stacking height — structures range from 30-150 feet, discharge heights up to 40 feet at 18-20° elevation.
• Belt width: Determined by TPH, material weight, density, sharpness, particle size, cohesiveness, moisture, and dust levels.
• Material properties: Weight, density, abrasiveness, and specific handling characteristics influence belt carcass selection — fabric belts for standard applications, steel cord for heavy-duty.
• Portability: Wheeled, tracked, or fixed — determines chassis design and mobility features.
