Gypsum loose bulk density measuring instrument is a professional gypsum testing instrument, mainly used for measuring the bulk density of building gypsum. The product meets the requirements of GB9776 standard. Be sure to read the instructions carefully before use. It is operated by professional experimenters to avoid injury caused by improper operation. For more information, please contact our customer service staff.
Gypsum loose bulk density tester by 1. Conical sieve. 2. Tripod bracket. 3. The measuring container (the upper part is an extension cylinder, the lower part is a bulk density barrel, and its capacity is 1 liter) is composed of three parts.
The main parameters:
1. Conical sieve aperture: 2mm,
2. Net weight: 30kg.
3. Dimensions: 300X260X120mm
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。
Gypsum loose bulk density tester use:
1) From the test room gypsum sample stored in the sealed container, 1000 g of the sample was taken out and thoroughly stirred, passed through a conical sieve having a pore diameter of 2 mm, and then measured twice by the same instrument as described below.
Weigh the volumetric drum without extension sleeve to the nearest 0.1 gram, install the sleeve on the bulk container, place it under the cone of the instrument, and pour the sample into the funnel in 100 gram portions. The sample was agitated with a brush and dropped through a screen into a bulk container. When the weight-bearing bucket with the extended sleeve is filled, the sleeve is removed without vibration, and the surface is scraped with a ruler to remove excess material until the surface is on the same level as the upper edge of the bulk density drum. Weigh the bulk container and sample to the nearest 0.1 gram.
2) Representation of the results:
Calculate the loose bulk density by the following formula, gram / liter
Where: m1 is the weight of the bulk density drum and the sample (g)
M0 is the weight of the bulk container itself (g)
If the difference between the two determination results is less than 5% of the smaller value of the two test results, the average value is taken as the loose bulk density of the sample; otherwise, it should be measured again, and the difference between the two measured values is less than 5%. Take the average again.
RZ-100 Gypsum Loose Bulk Density Tester is used for placement:
The instrument should be placed in an environment free of non-corrosive media and placed on a platform of appropriate height. If necessary, adjust the three conical nuts on the lower part of the tripod bracket to the horizontal position.
1) Clean and wipe clean after use;
2) Place the desiccant on the screen.
