Kwatani also custom designed a vibrating screen for a gold mine to handle 1,500 mt/h of solids and 2,000 m 3 /h of slurry with a screening efficiency of +95% at a desired cut point of 0.5 mm. This 3-m-wide horizontal vibrating screen significantly increased the total plant capacity while ensuring 0% slurry carry over at the screen discharge.

In summary, the above simulation demonstrates that aggregate customization is likely to be effective depending on the size of β and σ 2 B.In general, situations where the β vector is away from zero with small variability are best suited to aggregate customization. Perhaps the most valuable aspect of the above simulation is its diagnostic ability to indicate if aggregate customization should

Screening efficiency measures how much of the desired aggregate is accurately separated during the screening process. For example, if your screens are operating at 80% efficiency, that means 80% of the desired aggregate size passes through the screens while 20% does not. Efficiency should be as close to 100% as possible, but keep in mind that

Specific gravity and Water Absorption Test of Aggregates are major important tests to be performed on aggregate. These two parameters or properties of aggregate play an important role in the mix design of concrete. As we know that aggregate occupies 70 to 80% volume of concrete, its testing becomes essential before use.

Firstly, it is necessary to be clear about screening efficiency. Suppose 50 tonne of feed material has say 40 tonne of (-) 10 mm size material. If you are screening for passing size of (-)10 mm, then if the screened content happens to be say 28 tonnes then the screening efficiency would be 28/40 = 70%.
