Multi‑silo material distribution is a critical process within aggregate processing facilities. Many existing projects rely on plow unloaders for belt conveyor discharging, yet this traditional solution brings obvious drawbacks under real‑world site conditions.
Plow unloaders work with open discharging architecture. Substantial dust generates while bulk material falls down. Retro‑fitted enclosures cannot fully contain dust emission due to inherent structural limits, which may cause non‑compliance under strict environmental regulations.
One individual plow unloader is required for each silo discharge position. More silos mean more plow unloaders and auxiliary drive assemblies. This takes up considerable footprint inside transfer stations, and increases routine maintenance workload across numerous units.
Also known as belt tripper car in global industry, the rail‑mounted mobile unloading truck suits belt width from 500 mm to 1400 mm, specially engineered for multi‑silo bulk material distribution.
The tripper runs on steel rails: 15 kg/m rail for B500‑800, and 18 kg/m rail for B1000‑1400. Travel speed is kept at 0.34‑0.38 m/s. Low‑speed travelling together with 2‑way or 3‑way enclosed hoppers enables multi‑point enclosed discharging and restricts dust leakage.
One single tripper unit can serve multiple silo points, removing the need for one plow unloader per silo, reducing total equipment count and system footprint. TJ2‑200 brake paired with MZD1‑200 electromagnet guarantees accurate positioning after travelling, ensuring material drops into target silos precisely.
When retrofitting or constructing aggregate conveying lines, three items shall be confirmed: actual belt width, on‑site rail load‑bearing capacity, silo quantity, to decide between two‑way hopper or three‑way hopper configuration.
Mobile unloading truck is not a universal replacement for all scenarios. For aggregate projects with strict dust requirements, limited layout space and multiple silos, it mitigates inherent weaknesses of plow unloaders and delivers a balanced solution for production, maintenance and environmental compliance.![]()
