— Ball mill classifier systems have been improved over time and are now capable of achieving much finer products. In the past, a particle size with a D97 of 10 microns was only possible. Now particle sizes down to a D97 of less than 3.5 microns can be achieved, with a D50 in the range of 1.5 microns.

The BLVT Classifier is designed to optimize the air and material flow inside the mill and minimize unnecessary internal recirculation. This is accomplished by controlling the gas speed distribution of the classifier from material entry to exit.

The Hosokawa Alpine ATR system in a circuit with a high-performance air classifier is the ultimate energy-saving solution for the gener-ation of ultrafine GCC fillers in the fineness range of d97 = 2.5 – 8 μm.

 — Ball Mill Breakage Efficiency. Consider a ball mill circuit processing material of a given feed size and at a given throughput rate to a target product size, the latter which once again distinguishes the "fines" from the "coarse" material.

Overview of our ball mills and agitated media mills. The classic ball mill Super Orion S.O. is suitable for dry hard crushing and achieves finenesses of under 10 µm. For superfine dry grinding: The energy-efficient Pulvis combines a vertical agitator bead mill with a high-performance classifier and is also suitable for grinding hard materials ...

 — In the "Functional Performance Characteristics of Ball milling" approach (McIvor, 1988–2008) the effects of milling parameters, circulating load and classification efficiency are quantified based on circuit surveys and laboratory testing.

Classification system efficiency (CSE) is a composite measurement of the net performance of the classification system in a ball milling circuit. Functional Performance, as developed by McIvor, defines Classification System Efficiency, as the net amount of coarse material in the ball mill (McIvor, 1988a).

In this module, you will learn how to characterize the performance of ball mill circuits. Specifically, after completing this module, you will be able to: List and describe the four elements of the functional performance equation for ball mill circuits. Define and calculate the classification system efficiency of a ball mill circuit.

Ball Mill and Air Classifier Production Line. Cooperate with the classifier to produce products of multiple particle sizes at the same time. The product particle size control is flexible, special design is adopted to reduce noise and emission. Automatic control, easy to operate.

However, to enable systematic optimisation of CSE, the effects of independent grinding circuit variables on CSE must be understood. Figure 1 shows a typical closed-circuit ball mill arrangement where new feed reports first to the classification equipment, in this …
