Compaction characteristics of crusher dust under modified compaction test have an Optimum Moisture Content of 11% and Maximum Dry Density of 2.02 g/cc. From the compaction curve it can also be seen that crusher dust attains higher densities with wider range of moisture contents and increases the workability at high moisture contents.

Cone Crusher Design. When the brothers invented the cone crusher over 60 years ago, they employed the principle wherein the length of the crushing stroke was related to the free fall of material by gravity. This permitted the material being crushed to fall vertically in the crushing chamber; and in effect caused the particles to be ...

Crusher run gravel. CD triaxial tests were performed using crusher run gravel that was scalped on the ½-inch sieve size. The grain size distribution curve for the scalped gravel is shown in Figure D.6. Density tests were performed on unscalped and scalped samples to provide a means of correlating field (unscalped) densities with lab

Also you have to know material feed top size and size reduction ratio. Based of this it is easy to calculate product top size. The next step includes type characteristics that depend on material hardness (i.e. for middle hard ore, the type characteristic is 1.9 for R=0). Based on this you can calculate the size of crusher discharge.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

This 10″ reduction crusher, with its 40″ head, compares closely, in this respect, with the 20″ standard crusher, which has a 38″ head. Using straight-face concaves, the permissible minimum open side settings are 1.5″ for the former, and 3.5″ for the latter. With non-choking concaves these settings are, respectively, 1 1/8″ and 2 1 ...
