drill bit length

Length-diameter ratio is the ratio of the depth of the hole processed to the diameter of the drill bit. For example, the drill bit diameter is 12.7mm and the hole depth to be processed is 38.1mm, so its length-diameter ratio is 3:1. When the length-diameter ratio is about 4:1 or less, the chip grooves of most standard high speed steel bits can.

What's the Difference Between SAG Mill and Ball Mill

 · The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach ~ , while the ball mill's.

Mill (grinding)

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 or by animals (e.g., via a hand crank), working.
