What's the Difference between Cold-Rolled and Hot-Rolled

Jan 10, 2019· The difference between the two is that cold-rolled steel undergoes an additional processing step after it has been hot rolled. To make cold-rolled steel, hot-rolled steel is transported to a mill where it’s cooled to room temperature and then re-pressed using rollers.

Difference between impact pulverizer and hammer mill

1. Hammer mill also called Coarse grinding mill, and the finished particle size is below 3mm, while the impact pulverizer's pellets are bigger. 2. Hammer mill works as the hammer, while the impact pulverizer works by plate extruding. 3. Hammer mill constitutes by liner, hammer, counter version, rotor, etc, while the impact pulverizer has no hammer.

Mill (grinding) Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Conveyor Roller, Idler roller, Carrying Roller, Impact

Impact rollers are used as carrying rollers instead of normal steel rollers at a loading point. On steel roller there are rubber rings assembled, side by side, to absorb the weight and impact of material falling onto the belt. At the same time impact rollers reduce the shock and vibration through the steel structure.

Mining Prospecting and exploration Britannica

Mining Mining Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and location with respect
