Trommel screen Wikipedia

A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material

Bone density Wikipedia

Bone density, or stone mineral density (BMD), is the amount of stone mineral in stone tissue. The concept is of mass of mineral per volume of stone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of stone surface upon imaging.

Dual-energy X-ray absorptiometry (DXA, previously DEXA) is a means of measuring stone mineral density (BMD) using spectral imaging.Two X-ray beams, with different energy levels, are aimed at the patient's bones.When soft tissue absorption is subtracted out, the stone mineral density (BMD) can be determined from the absorption of each beam by bone. Dual-energy X-ray absorptiometry is the
