Operators keep a close eye on the equipment to catch malfunctions or safety issues early, while also tending accessory machinery like pumps and conveyors that keep material flowing through the line. Regular weighing and measuring checks confirm the output matches spec, and operators log that data along with any problems on production forms before cleaning and adjusting the machines themselves. Because the raw material varies so much, from mining to food processing to glass manufacturing, the specific industry often shapes the daily routine more than the job title does; it's typically a high school diploma role learned on the job.
Pros
Accessible entry with just a high school diploma and on-the-job training
Hands-on process work operating and maintaining heavy industrial machinery
Meaningful independent judgment in monitoring and adjusting equipment day to day
Cons
Above-average hours, often exceeding a standard 40-hour work week
Employment projected to shrink by 2.5% over the next decade
Only about 2,700 positions nationwide in a fairly narrow industrial niche
A typical day
The crusher circuit starts up in sequence after the morning inspection — jaw, cone, screens, conveyors — and the first hour is spent watching the flow settle: feed rate steady, product size sampling within spec, no strange sounds from the bearings that were greased last week. The shift alternates between the control station and the catwalks: weighing product samples at set intervals, adjusting the gap setting when the gradation drifts, clearing a jam when an oversized rock bridges the feed opening (locked out, every time, no exceptions). Dust suppression sprays and pumps need tending; the log sheet fills with tonnage, hours, and the vibration reading that maintenance will want to see. It's loud, dusty, rhythmic work that rewards mechanical instinct.
Tasks at the job
Observe operation of equipment to ensure continuity of flow, safety, and efficient operation, and to detect malfunctions.
Tend accessory equipment, such as pumps and conveyors, to move materials or ingredients through production processes.
Weigh or measure materials, ingredients, or products at specified intervals to ensure conformance to requirements.
Record data from operations, testing, and production on specified forms.
Read work orders to determine production specifications and information.
Clean, adjust, and maintain equipment, using hand tools.
Workplace & working conditions
Work happens indoors, though not always in a climate-controlled space, and most of the day is spent on your feet. Noise levels can be distracting or uncomfortable. The role involves regular exposure to hazardous equipment or conditions and contaminants and working at heights, and specialized protective equipment is standard.
There's a regular, moderate amount of time pressure, and you're expected to exercise significant independent judgment day to day.
Education necessary or common
High school diploma; some on-the-job training or apprenticeship
Licenses & certifications
MSHA Part 46 training (surface mines/quarries)
OSHA 10
Mobile equipment certifications (employer-provided)
