The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of …

Yes, it is possible to run two ball mills in closed circuit with a single common separator (3rd generation would be better), that must be able to threat the sum of the two circulating loads coming from the two mills simultaneously. The process run conditions of the separator have to respect the feed maximum material to process air ratio (A/Q) of 2,2 – 2,5 kg/m3.This possibility is feasible ...

The IsaMill™ has real-world success in 129 metalliferous installations across 21 countries. It's the world's only horizontal fine-grinding mill, so it avoids short-circuits, is highly efficient and gives the highest availability. IsaMill™ has accurate scale-up and is proven consistently.

Ball mills can be designed to operate continuously (fed at one end of the system and discharged at the other), or on a batch basis for smaller, or intermittent volumes. They can also be operated either on a stand-alone basis ('open-circuit grinding') or in conjunction with a classifier which returns oversize product to the mill for further grinding ('closed-circuit grinding').

Slide 3 circulating load ratio : As the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit. Circulating load circulating load ratio New feed circulating load ratio [8] 4.

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

Closed circuit ball mill – Basics revisited

The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over

and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.
