3. Main parameters: ★ Density bucket: 1L in volume. ★The funnel is stainless steel ★Stent diameter is 8mm round steel ★The chassis is 2mm thick stainless steel ★The chassis, funnel and bracket can be welded and riveted ★The bottom surface of the funnel mouth is 100mm/stainless steel from the top surface of the bulk density barrel ★Aperture of cone screen: 2mm, ★Net weight: 30kg.

四、使用方法：

★从保存在密封容器内的试验室石膏样品中，取出1000克试样，并充分搅拌均匀，使其通过孔径为2毫米的锥形筛，然后按下述步骤用同一仪器测定两次。

称量不带延伸套筒的容重桶，精确至0.1克，在容重桶上装上套筒，并将其放在仪器的锥形漏斗下，将试样以100克为一份倒入漏斗中，用毛刷搅动试样，使其通过筛网落入容重桶中。当装有延伸套简的容重桶填满时，在避免振动的情况下移去套筒，用直尺刮平表面，除去多余物料，直至表面与容重桶上缘位于同一水平面上为止。称量容重桶和试样重量精确至0.1克。

★结果的表示方法：

按下式计算松散容重，克／升

r=m1-m0

其中：m1是容重桶和试样的重量（克）

m0是容重桶本身的重量（克）

如果两次测定结果之差，小于两次试验结果较小值的5 % ，则以平均值作为试样的松散容重；否则，应再次测定，至两次测定值之差小于5 %。再取其平均值。

4. How to use: ★Take out 1000 g of gypsum sample from the laboratory gypsum sample stored in a sealed container and stir it evenly to pass it through a cone-shaped sieve with an aperture of 2 mm, and then use the same instrument to measure twice as follows. Weigh the bulk density bucket without extension sleeve to the nearest 0.1 g, install the sleeve on the bulk density bucket, and place it under the conical funnel of the instrument, pour the sample into the funnel in 100 g portions, Stir the sample with a brush to make it fall through the screen into the bulk density bucket. When the bulk density bucket with the extension sleeve is full, remove the sleeve while avoiding vibration, and use a ruler to smooth the surface to remove excess materials until the surface and the upper edge of the bulk density bucket are on the same level. Weigh the bulk density barrel and the sample weight to the nearest 0.1 g. ★Expression of results: Calculate loose bulk density by the following formula, g/l r=m1-m0 Among them: m1 is the weight of the bulk density barrel and the sample (g) m0 is the weight of the bulk density bucket (g) If the difference between the two measurement results is less than 5% of the smaller value of the two test results, the average value shall be used as the loose bulk density of the sample; otherwise, it shall be measured again until the difference between the two measurement values is less than 5%. Then take the average value.

五、使用安放：

本仪器应安放在无震源无腐蚀介质的环境中，并置于适当高度的平台上。必要时可调整三脚支 架下部的三个锥形螺母使其至水平位置。

Five, use and place: The instrument should be placed in an environment with no seismic source and no corrosive media, and placed on a platform with an appropriate height. If necessary, adjust the three conical nuts on the lower part of the tripod to a horizontal position.
