Cylindrical roller bearings are the most basic type of roller bearing and use rollers instead of balls as a rolling element. These rollers are slightly crowned and have a greater length than width. Most cylindrical roller bearings are single row with a cage that houses and spaces the rollers. They are ideal for heavy radial loads at high speeds.
A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations.Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion.

Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive.
A Closer Look at Machine Styles. Three-roll initial-pinch (see Figure 5) or single initial-pinch plate rolls generally are for light-capacity applications and may be electromechanical or hydraulic. They work by pinching the flat sheet between two vertically opposed rolls while the third, offset roll—or bending roll—moves upward to contact and then bend the sheet.
Just like the soft mining caps that were used to hold oil-wick or carbide mining lamps, mining helmets were used to hold the new electric cap lamp. The lamp sat in a bracket at the front of the helmet, with the cord running along the helmet's crown, guided by a cord holder in the back of the helmet to route the cable directly to the battery
II. Rock Roller Bits: These are suitable for hole diameter between 75 mm and 300 mm. In mining areas these are commonly used for drilling large diameter holes in mechanised quarries. Flushing of the hole with compressed air instead of by water under pressure is the common practice with this type of bit.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
