首页 >> bulk density determination after crushing
The actual density of crushed stone can be up to two times greater than the bulk density - if the building material is not pre-compacted. Stones, whose fraction turned out to be too large, for example, from 120 mm in diameter, are additionally crushed on a stone crushing machine to the desired fraction.

While this material has about 5-15% of its volume made up of openings between the individual particles, these opening or porosity are very hard to see because of the very small particles that make up the material. These materials typically have a bulk density of 1.90 to 1.72 g/cm³.

For many purposes, result with sufficient accuracy can be obtained by using the density of quartz (2.65 g/cm 3) as the grain density. A method of determining the gain volume is crushing the sample after determining the bulk volume, thus removing all pores including the non-interconnecting ones.

Bulk density is the amount of powder by weight that is present in a defined volume. It is usually expressed as g ml −1 and is obtained by measuring the volume of a fixed weight of powder after it has been tapped for a defined number of times. A high bulk density is very important in packaging and transportation, and is desirable as it can significantly reduce costs.

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).

The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction. The density of quartz is around 2.65 g/cm 3 but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm 3.In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm 3) due to …

The experimental process used in the study was to take a single source coke and crush it down to −0.6 +0.3 mm using a range of different laboratory crushing methods. The shape and bulk density of the crushed coke was then determined; shape was then correlated with crushing method, and bulk density correlated with particle shape .
