The client is a large enterprise specializing in the production and sale of building materials, currently planning to establish an automated production line for manufacturing new products.
Our company is responsible for the automated raw material handling system, which will process three types of materials: aluminum dross, chimney ash, and quicklime. The system encompasses processes including unpacking, feeding, screening, storage, conveying, and weighing/dosing. The system is designed for a capacity of 18 tons per hour, with a maximum conveying distance of 180 meters and a conveying height of up to 10 meters.
Within the system, two ton-bag feeding stations are dedicated to feeding aluminum dross and chimney ash respectively. The aluminum dross feeding station is specially equipped with a screening machine to remove larger aluminum particles. The remaining aluminum dross and flue dust then fall by gravity into buffer silos and are conveyed via fan-driven pipelines to weighing tanks.
Quicklime is automatically fed from tank trucks into large storage tanks for sealed storage, effectively resolving the customer’s material storage challenges. Materials from storage tanks are then conveyed to weighing tanks via a fully automated system requiring no manual intervention. This significantly reduces labor costs and prevents dust leakage.
Weighing tanks automatically measure materials according to pre-set formulas from the central control system, ensuring high precision in the batching process without manual operation and effectively minimizing human error. The system achieves measurement accuracy within 0.3%, guaranteeing product consistency and fully meeting the client’s production requirements. Through this project, Wijay successfully implemented centralized material storage, automated conveying, automatic weighing, and precision measurement functions, significantly reducing the client’s production costs while enhancing overall production efficiency.
