What is a Bridge Rectifier : Circuit Diagram & Its Working - ElProCus

The last stage of this regulated DC supply is a voltage regulator that maintains the output voltage to a constant level. Suppose the microcontroller works at 5V DC, but the output after the bridge rectifier is around 16V, so to reduce this voltage, and to maintain a constant level - no matter voltage changes in the input side - a voltage regulator is necessary.

Cold drawing principles - The Fabricator

Drawing a tube from one size to another sounds simple. The process has two main steps: crushing one end (also known as pointing the tube), then drawing it through a die that has the correct ID. When the process is finished, the tube's OD matches the die's ID. In reality, it's much more complicated than that.

Ball Mill - an overview | ScienceDirect Topics

The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.
