The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall. The transition zone consists of 50 mm and 60 mm balls. The basis is a 50 mm ball size for 5% residue on the 4 mm sieve. In case bigger grains are by-passing the partition through the center grate even% Steel Charge Loading in Mill = 113 126 H/ D .

Ball mill for cement grinding FLSmidth
Cement grinding with our highly efficient ball mill. 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 FLSmidth ball mill isSteel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are used in the coarse grinding chamber, φ20–50mm steel balls are used in the fine grinding chamber. 2.How to choose proper grinding media for your ball mill

Optimization of continuous ball mills used for finish-grinding
The ball mill is equipped with a classifying lining with a conical undulated shape. The absolute lifting height is quite similar to an industrial used liner plate. The discharge diaphragm is of the slotted type. The ball charge grading used during most of the test runs was an industrial standard grading with balls between 12 and 20 mm.An increase of over 10% in mill throughput was achieved by removing the ball scats from a single -stage SAG mill. These scats are non- spherical ball fragments resulting from uneven wear of balls(PDF) Performance optimization of an industrial ball mill for

Determining cement ball mill dosage by artificial intelligence
A mill's ball charge may vary, depending on the qualities and other characteristics of the material being used. High quality cement grinding in this type of mill mainly depends on the mill load ball, adjusting the separator, the hardness of the material during grinding and the time taken for grinding the material.Batch grinding parameters a T 0.63 min −1 γ 0.80 α 1.37 Λ 4.7 β 6.2 Φ 0 0.60 δ 0.1 a T 1.12 mm Table 2 Average input values for the full-scale mill and their corresponding interval rangesOptimization of the make-up ball charge in a grinding mill

These systems are sensitive to oversized clinker pieces that have a tendency to accumulate and clog the ball charge causing the cement to flow around or over the ball charge instead of through it. In other cases, the mill grinding condition appears normal but the specific power consumption may be above average, e.g. more than 40
