石膏松散容重测定仪由1．锥形筛。2．三脚支架。3．测量容器（上部是延伸筒、下部是容重桶，其容量是1升）三部分组成。
gypsum loose bulk density tester by 1. conical screen. 2. tripod stand. 3． the measuring container (the upper part is an extension tube and the lower part is a bulk tank with a capacity of 1 liter).
石膏松散容重测定仪主要参数：
锥形筛孔径：2mm，
2、净重：30kg。
main parameters of gypsum loose bulk density tester:
1. conical screen aperture: 2mm,
2. net weight: 30kg.
石膏松散容重测定仪使用方法：
1）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。
2）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。
how to use gypsum loose bulk density tester:
1) from the laboratory gypsum sample stored in a sealed container, take a 1000-gram sample and stir it well enough to pass it through a conical sieve with a diameter of 2 mm, and then use the same instrument to measure twice according to the following steps.
weigh the bulk tank without extension sleeve to the nearest 0.1 g. install the sleeve on the bulk tank and place it under the conical funnel of the instrument. pour the sample into the funnel in 100-gram portions. agitate the sample with a brush to drop it through a sieve into a bulk tank. when the bulk tank with the extension sleeve is filled, remove the sleeve while avoiding vibration, and scrape the surface with a ruler to remove excess material until the surface is on the same level as the upper edge of the bulk tank. weigh the test cylinder and sample weight to the nearest 0.1 gram.
2) representation of results:
calculate loose bulk weight according to the following formula, g / liter
r = m1-m0
where: m1 is the weight of the bulk tank and the sample (g)
m0 is the weight of the bulk tank itself (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 is used as the bulk density of the sample; otherwise, the measurement should be repeated until the difference between the two measurement values is less than 5%. then take the average.
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。
rz-100 plaster bulk density tester is placed:
the instrument should be placed in an environment free of vibration sources and non-corrosive media, and placed on a platform of appropriate height. if necessary, adjust the three cone nuts on the bottom of the tripod stａnd to the horizontal position.
维护保养：
