Sidewall conveyor

The core feature of the sidewall conveyor is the flexible sidewall and diaphragm structure added on both sides of the conveyor belt. This equipment is mainly used to solve the technical limitation that traditional conveying equipment can only operate at a fixed angle, and can adapt to vertical lifting or large-angle conveying scenarios. Its applicable materials include block materials with a particle size of less than 500mm and powder materials with a fineness of less than 200 mesh, including ore, coal, grain, chemical raw materials, etc. By adjusting the height and spacing of the diaphragm, the equipment can match the flow characteristics of different materials and provide a stable and reliable conveying solution in the field of bulk material processing. Working principle of sidewall conveyor
The operation of the sidewall conveyor depends on the synergy of the base belt, sidewall and diaphragm. As the load-bearing body, the base belt is usually made of high-strength rubber or rubber and fabric composite materials, and the surface is covered with a wear-resistant rubber layer to extend the service life. The sidewall is fixed on both sides of the base belt in a wavy structure, and the height range is usually 40mm to 300mm. It is made of polyester fiber or steel wire rope reinforced rubber material, which has both flexibility and tear resistance. The diaphragm is installed vertically on the surface of the base belt, and the spacing is adjusted between 200mm and 800mm according to the material characteristics to form an independent material carrying unit. During the material conveying process, the drive system is configured with double rollers or multiple rollers, and the variable frequency speed regulating motor drives the conveyor belt to move. When the conveying angle exceeds 30°, the material forms a stable friction contact with the sidewall and the diaphragm, and stable conveying is achieved through mechanical balance. In the vertical lifting scenario, the equipment adopts a Z-type or C-type layout to achieve 90° material lifting by changing the conveying direction. To ensure the stability of operation, the equipment is equipped with a hydraulic automatic tensioning or spiral tensioning mechanism to adjust the tension of the conveyor belt in real time, and is equipped with an anti-deviation device to maintain the deviation control accuracy within ±15mm through a pneumatic or hydraulic deviation correction mechanism. During the material unloading stage, the sidewall conveyor is equipped with a mechanical cleaning device and a vibrating discharger. The cleaning device removes the adhered material by rotating the brush, and the vibration frequency can be adjusted from 50Hz to 200Hz to ensure that the thickness of the residue on the surface of the base belt is less than 0.5mm. For sticky materials, an air cannon auxiliary cleaning system can be installed to achieve deep cleaning through pulse airflow. Application of sidewall conveyor
In the mining field, sidewall conveyors are used for mid-stage transportation after ore crushing. The conveying angle can reach 60°, and the conveying height of a single machine exceeds 200 meters. In view of the space limitations of open-pit mines, the equipment adopts a modular truss structure, and the length of a single truss is adjustable from 6m to 12m to meet the layout requirements of complex terrain. In the bulk cargo loading and unloading of ports, the equipment forms a linkage system with ship loaders and ship unloaders to achieve efficient transportation of materials such as coal and ore, and the processing capacity of a single machine can reach 3,000 tons/hour.
In the building materials industry, the cement raw material conveying system uses a high-temperature resistant sidewall conveyor, which can operate continuously at 120°C, and the spacing between the diaphragms is optimized to 300mm to adapt to the characteristics of powdered materials. In the chemical industry, anti-corrosion equipment is configured, the base belt is coated with fluororubber, and the sidewall structure is additionally coated with polytetrafluoroethylene to meet the transportation needs of corrosive materials such as acids, alkalis, and salts.
In the field of grain storage, the equipment is used for the storage and transportation of grains such as wheat and corn. By adjusting the conveying speed to 0.8m/s, dynamic quality control is achieved with the online moisture detector. In the metallurgical industry, the sintering ore conveying system adopts a double-layer sidewall structure, with the upper layer conveying 10mm to 50mm block ore and the lower layer recovering powder below 5mm, and the comprehensive utilization rate is increased to 98%. The sidewall conveyor significantly reduces the floor space through the large-angle conveying design, which is particularly suitable for operating scenarios with restricted terrain or compact space. Its modular structure supports the rapid replacement of sidewalls and diaphragms, and the single maintenance takes a short time and has low maintenance costs. In addition, the sidewall conveyor can adapt to various working conditions such as open air, indoor, and corrosive environments. By optimizing the roller group structure and adding a soundproof cover, it can meet the noise control requirements in different scenarios.
