The Schopper chondrometer is a device used to measure the compacted bulk density of grain, also known as its test weight.

From the QCCF coal receiving pit, the raw coal is sent to the screening machine to be screened to ensure the grain sizes for the whole machine are within the required range of 6-50 mm. The machine that performs this process is the air-heavy medium separating machine. The air-heavy medium forms a fluid bed with stable density, separating the screened coal into cleaned coal and tailings. The ash content of the cleaned coal produced in this process is generally below 15%.  6, record 3, English, - sized%20coal

Among the alkaloids produced by grass endophytes, the best known are ergot alkaloids because they are also produced by related fungi known for major poisoning events throughout history. The ergot alkaloids are so named because they are made by ergot fungi; that is, Claviceps species. "Ergots" are hard, dense resting structures of these fungi that typically replace the reproductive structures of Claviceps-infected grass florets. Ergots mimic the size, shape, and density of the seeds, so with traditional winnowing they tend to be retained in the grain rather than being removed with the chaff.  2, record 7, English, - ergot%20alkaloid

Compaction mould samples. During desiccation events a soil will experience shrinkage induced stresses. These stresses are likely to slightly alter the grain orientation, residual stress and density of the soil in a similar manner to altering the compaction parameters. The associated effects of this density change have been simulated through the use of artificially made samples. The approach examined the effect of different compaction density and moulding water content upon the soil suction-water content relationship(ie the water retention characteristic).... it is evident that the water retention characteristic is shifted upwards as compaction density decreases and moulding water content increases. This means that the water content is increased for a given value of soil suction.  3, record 14, English, - moulding%20water%20content

The "Index-grain apparatus"(...) is a sedimentation device in which the free fall of grains is slowed by three nozzle-like constrictions which cause turbulence that results in better grading of the grains. In order to distinguish between the single grain fractions which settle in a graduated, conical, water-filled sedimentation vessel, a colored index set of three known grain fractions is added to the sediment before separation : 1 cm^three black grains in the grade 0. 02-0. 035 mm 1 cm^three red grains in the grade 0. 063-0. 11 mm 1 cm^three black grains in the grade 0. 2-0. 35 mm(...) The suspension with the added index set is poured into the filling tube, which is closed from below with a float stopper. The stopper is opened by squeezing a rubber bulb on the filling tube, and the suspension can immediately enter the lower sedimentation tube. The filling tube has a constriction that generates turbulence. The grains therefore enter the sedimentation tube pregraded. By multiplying the percentage volumes of the individual grades(minus the added colored index grains of each grade) by the average bulk density [(gamma]=1. 56), the weight-percentages of the individual grades are calculated on the basis of 100% dry material.  1, record 23, English, - Index%2Dgrain%20apparatus
