Mining | One who operates conical rolls that separate stone from clay, preventingmachine from jamming by regulating flow of clay into it. (references) |
Occupations | Tends machine that flattens and dries oilseed, such as soybean, cottonseed, and corn, and presses it to extract oil: Turns handwheels to adjust distance between rollers that flatten oilseed. Starts rollers and turns gate valve to admit oilseed. Observes rolling process to ensure that pressure of rollers on oilseed is not sufficient to extract oil. Turns control of heat drier to specified temperature, and opens chute to admit flattened oilseed to drier. Turns steam valves of heat cooker to cook dried oilseed. Turns handwheels to adjust roller pressure of oil expeller. Feels samples of expelled oilseed to determine that sufficient quantity of oil has been removed. May tend attrition mill that breaks up dehydrated oilseed [MILL OPERATOR (grain-feed mills)]. May tend filter press to filter oil [PRESS TENDER, HEAD, FEED HOUSE (grain-feed mills)]. May be designated according to process phase as Crusher Tender (oils & grease); Drier Tender (oils & grease) II; Oil-Expeller (grain-feed mills; oils & grease). (references) |
| Drives heavy rolling machine (road roller) to compact earth fills, subgrades, flexible base, and bituminous surface to grade specifications preparatory to construction of highways, streets, and runways: Moves levers, depresses pedals, turns handwheels, and pushes throttle to control and guide machine. Drives machine in successive overlapping passes over surface to be compacted. Determines speed and direction of machine, based on knowledge of compressibility of material under changing temperatures, so that ridges are not formed by excessive pressure. Pushes hand roller and pounds surfaces, using hand tamp, or guides portable power roller over areas not accessible to road roller. May be designated according to surface rolled as Road-Roller Operator, Hot Mix (construction); Subgrade-Roller Operator (construction); or according to source of power used as Diesel-Roller Operator (construction); Gas-Roller Operator (construction).

| Operates roll mill to homogenize and roll plastic compounds into sheeting or slab form: Pushes button to transfer plastic from mixing machine to revolving heated mill rolls. Cuts material with knife and feeds material back through rolls to obtain sheet of specified color, consistency, and thickness. Adjusts slitting knives or starts automatic scraper to strip sheet from rolls. Guides material onto conveyor belt. Observes gauges or feels material and turns steam and water valves to control temperature of rolls. Cleans rolls to prevent contamination of stocks, using wire brush, hand scraper, solvents, and airhose. May adjust roll clearance with hand wrenches. (references) | |
| Tends machine containing rolls that form cooked grain into flakes, shredded biscuits, or other shapes to produce cereal products: Moves controls to start pairs of rollers rotating and to convey cooked grain to roll feeders. Turns dials and handwheels to adjust pressure of rollers to maintain specified thickness and consistency of formed product, as indicated by feel and visual inspection, and to control rate of feed of grain through feeding mechanism. Replaces worn knives used to scrape formed grain from roller surface, using handtools. (references) | |
