The density can vary based on the properties of the original concrete mix design, the crushing process, and the size/grading of the crushed concrete. ... Feed concrete chunks into a jaw crusher capable of 1-2" output gradation. Screen crushed concrete through a 1-1/2″ screen into coarse and fine fractions.

The largest size of ore pieces mined measured 560 mm (average) and the smallest sizes averaged 160 mm. The density of the ore was 2.8 t/m3. The ore had to be crushed in a C-63 type jaw crusher 630 x 440. At a reduction ratio of 4, 18 % of the ore was below the maximum size required. Determine: (a) The maximum operating capacity of the crusher ...

Here's how you can use the crushed stone calculator: Select your surface shape, e.g., Rectangular.. In surface length, enter the length of your surface, e.g., 12 feet.. In surface width, enter the width of your surface, e.g., 8 feet.. Now, enter in depth, how deep do you want to fill the layout of your surface, e.g., 3 inches.. The waste factor tells how much crushed stone wastes …

jaw crusher production capacity. Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm): Pp = 2800 (2.8 SG) ... The numerator is calculating the volume of one swing of a jaw, times the density of material in the chamber, times the number of cycles per minute. This should give you the mass of material crushed per minute.
