Perlite Manufacturing Worker
ぱーらいとせいぞうこう
Industry & Occupation
Classification
Summary
This occupation involves crushing volcanic glass raw ore and rapidly expanding it through high-temperature heating to manufacture lightweight aggregate perlite. Production is managed with control over particle size and quality for use in building materials and agricultural supplies.
Description
Perlite manufacturing workers finely crush volcanic glass raw ore (perlite raw stone) using rollers or crushers and produce porous lightweight aggregate perlite by rapidly expanding it in a high-temperature furnace. After expansion, particle size is adjusted with sieving equipment, followed by quality inspections such as appearance checks and specific gravity measurements before shipment. Work sites involve high-temperature environments and dust generation, requiring the use of safety gear like dust masks and heat-resistant gloves, as well as simple equipment maintenance and cleaning. Production lines are operated by teams, often with shift work. Knowledge of safety and health management and process improvement is also required.
Future Outlook
While stable demand continues as a construction material, the adoption of labor-saving and automation technologies is progressing, heightening the importance of production efficiency and quality control.
