A sidewall belt conveyor — also called a steep incline belt conveyor or corrugated sidewall belt conveyor — is a continuous bulk material conveying system capable of transporting materials at any angle from 0° to 90°, including fully vertical lifts. The system consists of three integrated components bonded to a rubber base belt: corrugated sidewalls running the full length of the belt, and transverse cleats spaced at regular intervals. Together, these form enclosed pockets that secure bulk materials throughout the entire conveying path, eliminating rollback and spillage regardless of incline angle.

ec@shyychina.comIn compound fertilizer (NPK) and urea production lines, materials must be elevated between process stages — granulator to dryer, cooler to screener, screener to coating machine — multiple times within a compact plant footprint. A conventional flat belt conveyor cannot exceed approximately 20°–25° without material rollback. A bucket elevator solves the angle problem but introduces high-impact transfer points where hygroscopic fertilizer granules break, generate dust, and absorb moisture. The corrugated sidewall belt conveyor eliminates both problems: a single continuous run handles horizontal feed, the incline transition, and steep elevation — with no inter-stage transfer chute, no granule breakage point, and no spillage of corrosive or regulated fertilizer materials.
Widely specified in NPK, urea, ammonium nitrate, and compound fertilizer plants for steep-angle elevation between granulator, dryer, cooler, screener, and coating machine stages. SYM's chemical-resistant (CR) cover compound is suited for nitrogen-compound dust and mildly acidic fertilizer plant environments.
Other Industrial Applications
Structural Components
•Base Belt — High-tensile rubber, transversely rigid and longitudinally flexible. Prevents deformation during the return run on wide belts. Conforms to international standards.
•Corrugated Sidewalls — Canvas-reinforced with diagonal overlapping layers. Dynamic fatigue tested. Bonded to the base belt via secondary vulcanization.
•Cleats — High-stiffness rubber compound, precision-molded. Cleat spacing equals an integer multiple of the sidewall wave pitch to prevent leakage at incline transitions and pulley wrap points.
•Drive Components — Head funnel, drive drum, belt press rollers, upper/lower idlers, redirecting drum, take-up device, empty-section cleaner.
Selection depends on your conveying angle, material bulk density, lump size, and required throughput. Submit these parameters to SYM's technical team and a specific recommendation will be returned within 24–48 hours at no charge.
There is no fixed minimum order quantity. Replacement belts are typically produced within 4-8 weeks from order confirmation. Complete system assemblies are confirmed at the quotation stage based on project scope.
Both options are available. Belt-only supply covers retrofit and direct replacement applications. Complete system supply includes drive unit, structural frame, pulleys, take-up device, motor, gearbox, and control panel — with factory acceptance testing before shipment.
Routine maintenance covers belt tension and tracking, cleat and sidewall condition inspection, idler lubrication, and drive component servicing. Cleats, sidewalls, and idlers are the primary wear items — all available as SYM spare parts with short lead times from Shanghai.
