Dec 23, 2015· How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity …
Let's say that you have a recipe that says to add sugar to the juice until the Specific Gravity reading is 1.072. So, you mix all the ingredients together as the recipe calls for, except for the sugar. You take a reading and find that your Specific Gravity reading is 1.046, but you need to be at 1.072.

A nominal mix is prepared with a cement of specific gravity 3.15. Any change in this value of specific gravity will affect the mix design. Hence, it is necessary to test the specific gravity of the cement procured before mixing process. This is the main reason why we ignore the use of old stock cement.
Cone crushers were originally designed and developed by around 1920 and therefore are often described as cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.
