The density of the granular lubricant (32) is higher than the density of the particulate (33).

The input material is a mixture of gangue and a seed material in the form of the desired material to be extracted from the gangue, or a material having a density substantially similar to the density of the desired material.

The density of the fibrous material (C) may be uniformor may vary.

The apparatus also has the capability to determine the density of the flowed material.

The preferred filler for the composite is metal which adds weight and density to the total material.

A set volume of the stream of material is continuously weighed (1) without interrupting the flow and the density of the material is determined.

The density of the explosive can be adjusted and different classes of explosives can be obtained.

Furthermore, since this resin composite material uses a carbon material as a starting material of the insulated fine powder, the specific gravity of the resin composite material can be reduced to 2 or less.

Once material that needs its density determined has been added to this container, the sampling unit indicates the density of the added material.

If the density of matter is less than the so-called critical density, the universe is open and infinite.

If the density of matter < critical density, the universe is open and infinite.

This device is used for determining the density of solids.

The curvature of space-time and the matter energy density become infinite here.

A method of controlling the pattern and density of material spread by a spreader is also disclosed.

The vibratory speed is in an inverse proportion to the density of matter.
