Technological breakthroughs

With the aim of reducing manual labour, ensuring safety, and improving the efficiency of product handling, Ninh Binh Phosphate Fertiliser Joint Stock Company has developed and applied the initiative “Design and Installation of Bag Chutes and Bag Stacking Bins onto Conveyor Racks”.

In the product handling stage, moving and stacking bags of ground phosphate fertiliser onto conveyor racks by manual methods previously required workers to perform numerous lifting, lowering, and arranging movements. This method was physically demanding, made it difficult to maintain uniformity in bag placement, and could result in misalignment during loading, transport, and storage.

To address this, the company researched a solution to partially mechanise the bag stacking process, focusing on the design, manufacture, and installation of a system of chutes and stacking bins tailored to the workshop’s practical requirements.

The chute is designed with an appropriate slope and contact surface, guiding the bags of ground phosphate fertiliser to the stacking position on the conveyor rack. The stacking bin shapes and holds the bags in place during stacking, reducing the number of times workers need to lift, lower, and manually adjust them.

This solution creates a link between the bagging and handling stages, enabling a smoother and more continuous process for placing products onto conveyor racks. Workers mainly perform adjustment and arrangement tasks at specific points, rather than carrying out the entire process manually.

Following implementation, the initiative has contributed to improved working conditions at the handling stage. Bags of ground phosphate fertiliser are stacked more securely on conveyor racks, reducing misalignment during lifting, transport, and storage. At the same time, the use of chutes and stacking bins has reduced manual labour, making operations more convenient and safer for workers.

From a simple improvement in the handling stage, the initiative has helped standardise procedures, reduce manual labour, and enhance the stability of the stacking process. This approach aligns well with the broader goals of equipment upgrading and production rationalisation, starting from the workshop floor.
