By grinding the surface area of the sample increase and the contact between the solvent and solute is improved.
1. You can stir it 2. You can heat it up so it boils 3. You can crush the material you are dissolving.
At lower temperature the solubility decrease.
Stirring amps up the speed and frequency at which particls collide.. or, in other words, the kinetic energy is increased by stirring, which ultimately speeds up the dissolving process
Three factors that speed up the rate of dissolution are increased temperature, increased surface area, and stirring the mixture.
By chemical procedures: grinding, dissolving, filtering, repeated crystallization/recrystallization processes.
Heating, grinding, stirring are physical processes.

Break up the solid
When preparing juice from a frozen concentrate, the process of dissolving can be sped up. Adding hot water ad stirring are both ways to speed up the process.
At lower temperature the solubility decrease.
lifting their loose particles by abrasion,grinding and by dissolving soluble material
By breaking up the solid, you are creating more surface area. Therefore, increasing the surface area will speed up dissolution.
For example, by increasing the temperature, by grinding the material, treating with chemicals.
