For better control of the aggregate particle size distribution, it is recommended that the CDW should be processed in at least two crushing stages. First, the demolition methodologies used on-site should be able to reduce individual pieces of debris to a size that the primary crusher in the recycling plant can take.

To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands. In the past, quarries produced a range of single-size aggregate products - up to 40 mm in size. Still, the trend for highly specified aggregate means products are increasingly finer.

An example of the effect that crusher setting has on the product gradation is as follows: If the target crusher setting is 3/8 in. (10 mm) but the setting is not checked and it wears open to 1/2 in. (13 mm), then the end result is a 15 percent decrease in the minus 3/8-in. (10 mm) material size. This is a substantial decrease in productivity.
