What is the steel ball in the glass for?

That's for mixing. Put it in, cover it and shake it. When the liquid passes by, the solid components or powder inside can be better stirred rather than agglomerated.

Add milk powder, whey protein and other solid drinks 4 102 into the water cup and shake it. 1653 is easy to agglomerate or melt incompletely. Springs can help solid drinks melt and prevent caking.

Extended data structure classification:

According to the mechanical properties, springs can be divided into tension springs, compression springs, torsion springs and bending springs, disc springs, ring springs, leaf springs, spiral springs, truncated cone scroll springs and torsion bar springs, and can be divided into cold spiral springs and hot spiral springs according to the manufacturing process.

Ordinary cylindrical springs can be made into various types according to the load because of their simple manufacture, simple structure and wide application. Generally speaking, the spring manufacturing materials should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance. Commonly used are carbon spring steel, alloy spring steel, stainless steel spring steel, copper alloy, nickel alloy, rubber and so on.
