The sieving method is used to separate different components from a solid mixture via separating particles of different sizes. The feedstock composition therefore is a mixture of materials of different particle size e.g. coming from a [[sizing]] pro-treatment or a [[drying|drying process]]. | The sieving method is used to separate different components from a solid mixture via separating particles of different sizes.

While sieving may appear rudimentary compared to more modern instrumental particle sizing techniques, it still requires several important considerations to obtain the best repeatable and precise results. Several factors must be considered when developing a robust sieving method or performing a routine quality analysis. Sample size, sieving duration, controlled agitation parameters and end point determination are all critical method variables which need to be addressed. | While sieving may appear rudimentary compared to more modern instrumental particle sizing techniques, it still requires several important considerations to obtain the best repeatable and precise results.
