Industry & Occupation
Classification
Summary
This occupation involves sieving raw materials for cement mortar products. It handles quality uniformity and particle size blending.
Description
The raw material sieving worker sorts raw materials such as aggregates and pulverized coal by particle size using multiple sieves (screens) in the cement mortar manufacturing line, removing foreign matter and uneven-sized particles. They operate sieving machines, perform quality checks through visual inspection, create records for each process, inspect and perform simple maintenance on safety devices, and supply appropriate raw materials to the subsequent mixing and molding processes. Although some factories are mechanized, inspections and visual confirmation tasks are often performed manually, requiring accuracy and continuous monitoring.
Future Outlook
It fluctuates with changes in construction demand, but due to the importance of quality control, automation technologies and labor-saving investments are expected to advance. There is potential for increased demand for process optimization through IoT technology introduction.
