CASE STUDY - FINISH MILLING - The Cement Institute

* SSA is the specific surface area (m 2 /kg) of the finished cement (final product). CLOSED CIRCUIT MILL ‑ ANSWER. i) Lower mill exit surface area means lower fineness in the mill itself and so less tendency for agglomeration, coating, over grinding, cushioning etc. Therefore, grinding is more efficient and a higher rate of surface production is apparent. Product SSA = 350 m 2 /kg; For open – circuit operation mill exit SSA

PARTICLE SIZE DISTRIBUTION AND SPECIFIC SURFACE

For the determination of the specific surface area (SSA), the Blaine method (BM) has been commonly used for cement [1- 3]. BM is a rather empirical method particularly designed for cements, and therefore its application for SCMs requires some adaptations. For example, a different plunger has been proposed by [4] to avoid removing it.
