In vertical conveying systems such as grain storage facilities, cement plants, and bulk material processing lines, conveyor belts must handle continuous lifting loads while maintaining dimensional stability and secure bucket fixation. Our bucket elevator conveyor belt is engineered specifically for these high-demand applications, delivering reliable vertical transport with enhanced strength and low elongation. Built on a high-strength fabric carcass, it features multiple reinforced plies designed to provide excellent tensile strength and resistance to tearing under heavy bucket loads. The belt is manufactured with precisely controlled thickness and rigidity to ensure stable tracking and secure bolt holding for bucket installation, minimizing the risk of misalignment or detachment during operation. Using high-quality rubber compounds, it offers strong resistance to abrasion, wear, and mechanical stress, ensuring durability in continuous service. With stable performance across a typical operating temperature range of -20℃ to +80℃, it is suitable for conveying materials such as grain, cement, sand, and other bulk goods in vertical systems. Compared to standard conveyor belts, this solution is optimized for elevator applications, offering a better balance of strength, dimensional stability, and service life—helping reduce maintenance, improve safety, and ensure efficient, uninterrupted material handling.
Carcass:
Optional special strengthened tear-resistant polyester canvas (EP) or steel cord tear-resistant layer—maintains low elongation (≤1.8%) and high tensile strength, bearing the weight of buckets and materials without deformation.
Top/Bottom Cover Rubber:
Wear-resistant rubber (Shore abrasion ≤120mm³) with high adhesion to buckets; the top cover resists friction from bucket bolts, while the bottom cover reduces wear from conveyor rollers.
Anti-Tear Layers:
1-2 layers of top/bottom cover breakers (steel cord or high-strength fabric) to prevent belt tearing from foreign objects (e.g., hard gravel) during material lifting.
Core Rubber:
High-elastic core rubber ensures tight bonding between carcass layers, avoiding separation under frequent vertical tension changes.
Optimized carcass rigidity and flexibility balance enables stable operation in vertical (0-90°) or steep-incline lifting, adapting to bucket elevator structures of different heights.
Special tear-resistant polyester canvas (EP) or steel cord tear-resistant layer provides tensile strength up to 400N/mm, bearing heavy loads of buckets + materials (single bucket load up to 50kg).
Low elongation (≤1.8%) reduces belt adjustment frequency; wear-resistant cover rubber (service life ≥24 months) lowers replacement costs.
Cover rubber has strong adhesion to bucket bolts (pull-out force ≥800N), preventing buckets from detaching during high-speed lifting (conveying speed up to 3m/s).
Stable belt operation ensures uniform material feeding; compatible with large-capacity buckets (≥20L), meeting high-throughput requirements (up to 500m³/h).
Special Options: Flame-resistant (MT668 for coal-fired power stations), heat-resistant (≤150℃ for asphalt mixing plants), acid-alkali resistant (for chemical fertilizer transport)

Q1:What is a bucket elevator conveyor belt used for?
A1:
A bucket elevator conveyor belt is used for vertical conveying of bulk materials such as grain, cement, sand, and minerals. It works together with buckets attached to the belt to lift materials efficiently in industries like agriculture, mining, and construction.
Q2:Why does a bucket elevator belt break or tear?
A2:
Common causes include excessive load, improper tension, poor belt quality, misalignment, and stress around bolt holes where buckets are fixed. Repeated impact and material buildup can also weaken the belt and lead to tearing or sudden failure.
Q3:What type of belt is best for bucket elevators?
A3:
Belts with high tensile strength, low elongation, and strong carcass construction (such as polyester or nylon) are preferred. In heavy-duty applications, steel cord belts may be used. The belt should also have good resistance to wear, impact, and temperature based on the working environment.
Q4:How do you choose the right bucket elevator conveyor belt?
A4:
Selection depends on material type, lifting height, load capacity, bucket spacing, and operating conditions. Important factors include belt strength, thickness, bolt hole reinforcement, and resistance properties such as heat or oil resistance.
