How do you visualize quantum spin?

I have previously read that the spin of a particle is comparable to angular momentum of a system or object on the macroscopic level. However, the quantum world is much different and all I can imagine is a minuscule ball rotating on it's axis.

You really should not be imagining that. The spin is an intrinsic property of a quantum particle and a quantum particle behaves nothing like a minuscule ball. The name "particle" is there for historical reasons.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
