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 ().

The Hot Issue of Motor Temperature Ratings EC&M

The basic ambient temperature rating point of most motors is 40°C. A motor rated for 40°C is suitable for installation where the normal surrounding air temperature does not exceed 40°C (104°F). This is the starting point. When the motor operates at full load, it has a certain temperature rise, which adds to the ambient temperature.
