For this purpose, clinker samples obtained from 15 different cement plants in Turkey were used. 1. Experimental The chemical and potential compound compositions of the clinkers used in this study are listed in Table 1. Grinding was carried out in a laboratory ball mill with 20-kg capacity. Size distribution of the mill charge is given in Table 2.

An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.

type of installation: ball mills, combined in circuit with an air classification system of varying generations and sophistications. Depending on the local market situation and product portfolio, VRMs are the most common solution to grind raw materials and cement. Roller presses are used mainly in combination with a ball mill for cement

Our results suggest that integrating an air classifier into an open-circuit ball mill can increase the production rate by 15% or increase the cement-specific surface area by 13%. A single-compartment mill entails a pre-milled feed for proper operation, whereas a two-compartment mill yields a finer cement product than a three-compartment mill.
