Hairise Provides Modular Belt, Slat Conveyor Chain And Automatic Conveyor System Solutions Since 2004.
Regular conveyors, such as belt or roller systems, are designed for one primary job: moving materials along a straight, horizontal path. To navigate corners or reach upper floors, they require bulky add-ons—like transfer stations, elevators, or lengthy ramps—that devour factory floor space. A typical warehouse moving grain from ground-level storage to a second-floor mixer might need 20 meters of belt conveyors plus a separate elevator, sprawling across valuable square footage.
Spiral conveyors’ spiral design crushes this inefficiency. By wrapping the conveyor’s “working part” into a rotating spiral within a tube or trough, they eliminate the need for linear paths. The spiral blade’s rotation pulls materials forward while leveraging gravity and centrifugal force to handle inclines and even vertical lifts. A spiral conveyor can ascend 90 degrees in just 3 meters of vertical space, replacing 20 meters of traditional conveyors and elevators.
This compactness is transformative for industries like food processing, where factory floors are crammed with mixers, ovens, and packaging lines. A bakery using a vertical spiral conveyor to move flour from storage silos to mixers reduces its material handling footprint by 60%, freeing up space for additional production lines. In pharmaceutical facilities, where cleanroom space is at a premium, spiral conveyors’ ability to move powders vertically through walls or ceilings eliminates the need for clunky ductwork or transfer belts.
Regular conveyors are inherently open systems. Belt conveyors, for example, rely on a flat surface to carry materials, but gaps bet·ween belts and frames, or sudden jolts, send powders, grains, or small particles spilling onto floors. In a cement plant, this means tons of valuable material wasted annually—and a hazardous, dusty environment that endangers workers’ lungs. In food facilities, open conveyors risk cross-contamination, as airborne debris or pests can land on exposed products.
The spiral design of spiral conveyors solves this with its enclosed structure. The rotating flight sits within a sealed tube or trough, creating a barrier that traps materials inside. Whether conveying fine flour, abrasive sand, or sticky sludge, there’s no room for spills or dust leakage. This enclosed design is a game-changer for:
Food and pharmaceuticals: Spiral conveyors meet strict FDA and EU 10/2011 standards by preventing contamination. A cereal manufacturer reported a 95% reduction in product loss after switching from open belt conveyors to enclosed spiral systems.
Chemical processing: Toxic or corrosive powders (like fertilizers or industrial chemicals) stay contained, protecting workers from exposure.
Mining and construction: Aggregates like gravel or coal no longer spill onto conveyor belts or floors, cutting cleanup costs and reducing slip hazards.
Regular conveyors struggle with materials that are sticky, moist, or irregularly shaped. Belt conveyors gum up when moving wet clay or dough; roller conveyors jam when handling stringy materials like wood chips or fibers. In wastewater treatment plants, for example, traditional conveyors often seize up when moving dewatered sludge, requiring frequent shutdowns for manual cleaning—a process that wastes hours and risks worker injury.
Spiral conveyors’ spiral design turns this weakness into a strength. The rotating flight acts like a built-in agitator, continuously loosening and pushing materials forward. Its helical shape creates a scraping action against the conveyor’s inner walls, preventing sticky substances from adhering and building up.
Moist materials: Sludge, wet sand, or dough is “scrubbed” by the spiral flight, ensuring steady movement without clogs. A municipal wastewater plant reduced unplanned downtime by 70% after installing spiral conveyors for sludge handling.
Fibrous or stringy materials: Wood pulp, animal feed, or recycled paper is chopped and pushed by the spiral, avoiding the tangles that plague roller systems.
Abrasive materials: Gravel or metal shavings wear down belt conveyors quickly, but spiral conveyors’ hardened steel flights resist damage, lasting 3–5 times longer in such environments.
Regular conveyors often struggle to maintain a steady flow of materials, especially when dealing with light, fluffy substances like flour or plastic pellets. Belt conveyors can create uneven “piles” as materials shift during movement; vibrating conveyors may shake fragile items (like seeds or granules) into fine dust. In industries where precise dosing is critical—such as chemical blending or pharmaceutical manufacturing—this inconsistency ruins batches and increases waste.
The spiral design of spiral conveyors delivers unmatched flow control. The rotating flight’s uniform pitch (distance between spiral turns) acts like a metering pump, moving a consistent volume of material with each rotation. Operators can adjust the spiral’s speed to fine-tune flow rates, ensuring exactly 50kg of powder is delivered to a mixer every minute.
Precision dosing: In fertilizer production, spiral conveyors ensure exact ratios of nitrogen and phosphorus, avoiding over- or under-dosing.
Gentle handling: Delicate materials like seeds or pharmaceutical granules are moved smoothly by the spiral flight, reducing degradation. A seed processing plant reported a 40% drop in broken seeds after switching from vibrating conveyors to spiral systems.
Uniform mixing: Some spiral conveyors are designed with specialized flights that blend materials as they move, eliminating the need for separate mixing equipment. This saves time and energy in industries like animal feed production.
A mid-sized chemical plant producing industrial adhesives faced recurring issues with its regular conveyor setup: open belt conveyors spilled sticky resin pellets, 占据 30% of the factory floor with ramps and transfers, and jammed weekly when moving thick, paste-like materials. After upgrading to spiral conveyors:
Space savings: Vertical spiral conveyors replaced 15 meters of belt conveyors and two elevators, freeing up 200 square meters for a new production line.
Waste reduction: Enclosed design cut resin spills by 98%, saving $12,000 annually in material costs.
Downtime reduction: Spiral flights eliminated clogs, reducing maintenance shutdowns from 8 hours/week to 1 hour/week.
The plant’s ROI on the spiral conveyor upgrade? Just 14 months.
Spiral conveyors don’t just move materials—their spiral design solves the fundamental flaws of regular conveyors: wasted space, spills, clogs, and inconsistent flow. By enclosing materials, handling tricky substances, and enabling vertical movement, they transform how industries from food processing to mining operate.
In a world where efficiency, safety, and precision matter more than ever, the spiral conveyor’s spiral design isn’t just an innovation—it’s a solution to the oldest headaches in material handling. For factories drowning in clogs, spills, or wasted space, the answer is clear: the spiral design doesn’t just move materials—it moves industries forward.
