The density of granite chippings can vary slightly depending on the specific type of granite and the size of the chippings. However, a typical range for the density of granite chippings is 150-170 pounds per cubic foot (2400-2720 kg/m³).

Here are some factors that can influence the density:

* Granite type: Different types of granite have slightly different densities.

* Chipping size: Smaller chippings will have a higher density than larger ones due to the increased surface area.

* Porosity: Granite is a porous material, and the amount of porosity can affect the density.

For a more specific density, you should consult the supplier of the granite chippings. They will be able to provide information on the exact type of granite and the density of the specific batch you are interested in.
