自然堆積密度計(jì)依據(jù)國家標(biāo)準(zhǔn)GB/T 16913.3-1997 GB/T16913-2008的規(guī)定設(shè)計(jì)、生產(chǎn)。本裝置適用于粉塵堆積密度的測定。試樣的采集請參考GB/T 16913.1-1997 粉塵物理實(shí)驗(yàn)方法第1部分：試樣粉塵的采集中的相關(guān)規(guī)定。
原理
粉塵從漏斗口在一定高度自由落下充滿量筒；測定松裝狀態(tài)下量筒內(nèi)單位體積粉塵的質(zhì)量，即粉塵堆積密度。
儀器結(jié)構(gòu)
1、漏斗(流出口直徑12.7 )
漏斗不銹鋼材料制成，其中漏斗錐度為60°±0.5°。
2、測量架
不銹鋼材質(zhì)，用于在粉塵裝入漏斗時(shí)防止粉塵下落。
3、天平（客戶自備）
稱量300g；精度0.01g。
4、量筒
本裝置配備一只容積為100ml的不銹鋼量筒，量筒內(nèi)徑為Φ39mm。
5、刮板
不銹鋼材質(zhì)，用于在粉塵裝入漏斗時(shí)去除多余的粉塵。
6、毛刷

Natural bulk density meter
On the basis of natural accumulation of the provisions of the national standard GB/T 16913.3-1997GB/T16913-2008 to the design and production of density meter. The utility model is suitable for thedetermination of bulk density of dust. Sample collection please refer to GB/T 16913.1-1997 dustphysics experiment methods. Part first: the relevant provisions of the collection of dust samples.
Principle
The dust from the funnel opening in a free fall height of full cylinder; Determination of bulk qualityunder the condition of the cylinder unit volume of dust, the dust density.
The structure of the instrument
1, the funnel (outlet diameter 12.7)
The funnel made of stainless steel material, wherein the funnel taper is 60 degrees plus or minus 0.5 degrees.
2, measuring frame
The stainless steel material, used to prevent the falling dust in the dust in the hopper.
3, the balance (customer owned)
The largest weighing accuracy of 0.01g 300g.
4, a
This device is equipped with a volume of 100ml stainless steel cylinder, the cylinder diameter is phi 39mm.
5, scraper
Stainless steel is used for removing dust into the funnel in unwanted dust.
6, brush
Cleaning instrument
