Chemical Product Raw Material Crushing Worker
An occupation that involves crushing raw materials to a specified particle size using equipment such as crushers in the chemical product manufacturing process.
Mineral Crushing Worker (Ceramics)
Manufacturing job that crushes and pulverizes minerals used as raw materials for ceramic products and adjusts them to the specified particle size.
Firing Worker (Abrasives Manufacturing)
Technical job that mixes and shapes abrasive raw materials, fires them in high-temperature kilns to control crystal structure, hardness, and particle size, and manufactures abrasives used as grinding materials.
Plaster of Paris Manufacturing Worker
This occupation heats gypsum ore in a high-temperature calcining furnace (kiln) to dehydrate dihydrate gypsum into plaster of Paris (burnt gypsum). It handles the entire process from raw material crushing, calcination, pulverization, blending, particle size adjustment, to packaging.
Shot Peening Worker
A shot peening worker is a technician who performs surface treatment work by introducing compressive residual stress into metal parts through high-speed collision of granular media such as sand or steel balls, thereby improving the parts' fatigue strength, wear resistance, and corrosion resistance.
Silicon Abrasive Manufacturing Worker
Silicon abrasive manufacturing workers produce abrasive products using silicon compounds as raw materials through processes such as crushing, firing, particle size adjustment, and bonding agent addition.
Sugar Crystallization Worker
Occupation that refines sugar liquor extracted from sugarcane or sugar beets, crystallizes it, and manufactures sugar. Responsible for processes such as decolorization, concentration, crystallization, centrifugal separation, and drying.
Ceramic Raw Material Grinder
Manufacturing worker who processes raw materials used in ceramic manufacturing into fine powder using a pulverizer and adjusts to the particle size suitable for the next process.
Trommel Worker (Ceramics Raw Materials)
Trommel workers classify ceramics raw materials using a rotary screening machine called a trommel, remove foreign matter, and adjust particle size as manufacturing operators.
Malt Grinding Worker
A manufacturing job that processes malt, the raw material for beer and whiskey, to an appropriate particle size using a grinding machine and manages quality.
