Reducing particle size results in an increase in surface area. The increase in surface area allows more solvent (water) molecules to interact with the substance, and this increases the rate at which that substance dissolves.
It exposes more of the solute surface to the water molecules.
As the particle size gets smaller, the surface area increases, and as the surface area increases, the ease with which water can hydrate the particles increases. When it is easier for water to hydrate the molecules, this increases the speed at which the solute dissolves.
It exposes more of the solute surface to the water molecules.
The solvent dissolves the solute. (The solute dissolves in the solvent.)
The smaller the particle the faster it dissolves. This is because the process by which a solute dissolves takes place at the surface of the solvent. That means the larger the surface area of a particle or solute, the faster the solute will dissolve.

For the amount of material in the particle the surface area of a small particle is greater than a larger particle. Said another way, the surface area per unit volume is greater for a smaller particle. Dissolving speed is related to the surface area. Therefore a smaller particle dissolves faster than a larger particle.
