Skirt belt conveyor

The skirt belt conveyor is a special continuous transportation equipment developed for the transportation of materials at large inclination angles. Its core features are the elastic skirt and transverse partition structure added to the edge of the conveyor belt. The conveyor belt system adopts a three-layer composite structure: the base belt is a high-strength synthetic fiber and rubber composite layer to provide basic bearing capacity; the skirt is combined with the edge of the base belt through a hot vulcanization process, and the height range covers 30-200mm; the transverse partition is arranged at equal intervals and forms an independent hopper structure with the skirt to effectively prevent the material from rolling back or spilling during transportation. Working principle and technical advantages
When the equipment is running, the drive device transmits power to the conveyor belt through the roller to form a circular running track. The material enters the hopper unit composed of the skirt and partition from the feed end. After moving to the specified height with the conveyor belt, the material transfer is completed in the unloading area by gravity or auxiliary unloading device. This structure breaks through the 18° inclination limit of the traditional belt conveyor, and can achieve a maximum vertical lifting of 90°, significantly reducing the equipment footprint.
The technical advantages are reflected in three aspects: First, the combined design of skirt and partition enables the equipment to have excellent material retention capacity, especially suitable for bulk material transportation with a particle size of 0-150mm and a bulk density of 0.5-2.5t/m³; second, the modular design concept enables the equipment to be configured with single drive, dual drive or multi-point drive system according to site conditions to meet different conveying distance requirements; third, the standardized interface design supports rapid disassembly and assembly, and the length of a single frame is usually 1-3m, which is convenient for on-site installation of complex space layouts. Core advantages and technical features of skirt belt conveyor
Spatial adaptability advantage
Skirt belt conveyor breaks through the space limitations of traditional conveying equipment, and its maximum inclination angle can reach 90°, realizing vertical lifting function and significantly reducing the equipment footprint. In the mine stripping project, the equipment transports materials from the mining site to the spoil dump at an inclination of 35°, saving 40% of the site space compared with the traditional conveying system. The urban waste treatment project adopts a vertical lifting solution, and the lifting height of a single machine exceeds 30m, which effectively solves the spatial layout problem of the waste incineration plant. The modular design of the equipment supports the flexible combination of single-section frames of 1-3m, adapts to complex conveying paths such as L-type and Z-type, and realizes three-dimensional material transfer from the yard to the ship loader at the port bulk cargo terminal. Material adaptability advantage
The equipment forms an independent hopper through the combined structure of skirt and partition, which effectively controls bulk materials with a particle size of 0-150mm and a bulk density of 0.5-2.5t/m³. In iron ore transportation, the skirt height is designed to be 3 times the maximum particle size of the material to ensure zero material spillage during the transportation process. For sticky materials with poor fluidity, a herringbone partition structure is adopted to increase the conveying efficiency by 25%. The raw material conveying system of the cement plant is equipped with a high-temperature resistant skirt belt, which operates continuously under 150℃ conditions, and the material metering error is controlled within ±0.5%, meeting the process ratio accuracy requirements. Operation reliability advantage
The core components of the equipment adopt a redundant design concept, and the drive device is equipped with a hydraulic coupling and a torque-limiting friction clutch for dual protection, which automatically cuts off the power transmission when overloaded. The base belt of the conveyor belt system has a tensile strength of 630N/mm, and the skirt material can be selected from natural rubber, chloroprene rubber or polyurethane. The temperature resistance range covers -30℃ to 120℃, meeting the requirements of extremely cold and high temperature working conditions. The roller group adopts labyrinth sealed bearings, and the service life exceeds 50,000 hours in the high salt spray environment of the port. The tensioning device has an adjustable stroke of 500-2000mm to ensure that the running tension of the conveyor belt is stable within the range of ±5% of the design value. The technical characteristics of the skirt belt conveyor are concentrated in its structural design and functional realization. The combination of the skirt and the diaphragm forms an independent hopper unit to ensure that the material remains relatively static during the conveying process, effectively preventing spillage and rolling back. In terms of operational reliability, the equipment is equipped with a tension detection and automatic adjustment system to ensure that the conveyor belt is always in the best working condition. Standardized processes are established for daily maintenance, the roller replacement cycle is extended, and the service life of key components exceeds 50,000 hours.
