The advantage of sand is that it is inexpensive and can be used in sacrificial applications, such as the wet density determination method described below, or when samples are very poorly compacted
ادامه مطلبDensity of Sand The density of sand is affected by whether the sand is packed (rammed) or loose, and whether it is wet or dry. When it is packed, the grains of sand are forced into tighter formation and more matter is in the volume. When the sand is wet, water is in the sand, also affecting the total matter in the volume.

ادامه مطلبParticle density and bulk density are two basic ways to express sediment weight. Particle density is defined as the mass of a unit volume of sediment solids. A simple example is that if 1 cm 3 of solid material weighs 2.65 g, the particle density is 2.65 g/cm 3. Particle densities generally fall between 2.60 and 2.75 g/cm 3 for mineral particles.

ادامه مطلبThe wet milling process involves using water to break down grains prior to milling. This allows the individual parts of the grain to separate from one another for easier harvesting. The wet mill process is a common method of harvesting grain for food components, but dry milling is more common for flour or ethanol production.
ادامه مطلبIn many cases it is necessary to know the wet/dry density of the soil in the field, especially before planning activities such as compaction. This becomes especially important such as the construction of earthen dams, embankments, etc., to control field compaction, i.e. to know how close the field values are to the laboratory values.
ادامه مطلبEvery mill is limited in cooling surface area and therefore limited to the maximum amount of energy that can be used for grinding. This dictates the installed motor power for a mill. The nominal energy density of a mill is the available energy per volume of milling chamber. Energy Density = Installed Motor Power (kW) Mill Chamber Volume (liters)
