Is a colloid mill for peanut butter actually necessary for a smooth commercial product?

A colloid mill for peanut butter is commonly used in commercial production to achieve the smooth, consistent texture consumers expect, by reducing roasted peanut particles to a fine, uniform size and evenly distributing natural oils throughout the paste. Without this level of shear processing, peanut butter tends to have a grainier texture and less stable oil distribution over its shelf life.
