Refractory Material Batching and Weighing Cart with Dust-Proof Interface 

The refractory-material batching and weighing cart with a dust-proof interface is an automated device specifically designed for refractory production, aimed at addressing the significant dust pollution, low weighing accuracy, and high labor intensity associated with traditional manual batching processes. 

Such devices typically feature the following core characteristics and functions: 

1.  Core Functions and Structure 

Automatic Travel and Positioning: The weighing cart (rail-guided trolley) can automatically move under multiple storage bins, accurately position itself, and perform batching in accordance with the recipe sequence. 

High-precision weighing: On-board high-precision electronic scales and an automated control system ensure that the batching error for each raw material is minimized, directly enhancing the quality stability of the finished refractory products. 

Dust-proof interface design: 

A dedicated dust-collection hood is installed above the weighing hopper or material-receiving port, enabling a sealed or semi-sealed connection with the discharge outlet of the storage bin. 

Dust-Extraction Connection: The dust collection hood is equipped with a dust-proof interface that allows direct connection to a central dust-collection duct or an on-board dust-collection system. During material discharge, the resulting dust is drawn away by negative pressure, effectively preventing external spillage. 

Flexible Connection Technology: Certain equipment employs flexible expansion sleeves or flexible connection pipes as dust-proof interfaces, accommodating variations in hopper height and minor misalignments during vehicle movement to ensure continuous sealing. 

2.  Typical application scenarios 

Metallurgical protective material production line: used for batching dry tundish materials, repair materials, and other similar products. 

Production of unshaped refractories: automated batching for castables, plastic refractories, and gunning mixes. 

Multi-variety, small-batch production: The system typically supports the storage of hundreds of recipes, making it well-suited for production environments where recipes are frequently changed. 

3.  Technical Advantages 

Environmental Compliance: The dust-proof interface effectively captures particulate matter, meeting increasingly stringent environmental emission standards and improving the workshop working environment. 

Efficiency improvement: High degree of automation results in significantly faster batching speeds than manual methods, and can 24 Continuous operation for hours. 

Data Traceability: Equipped with an upper-level monitoring system, all ingredient data are automatically recorded and stored, enabling full traceability of the raw material sources and formulation details for each production batch. 

Our company, Wuxi Xielì, provides custom-designed and manufactured production lines for such batching weighing carts and automated batching systems.
