自然堆积密度计

自然堆积密度计依据国家标准GB/T 16913.3-1997   GB/T16913-2008的规定设计、生产。本装置适用于粉尘堆积密度的测定。试样的采集请参考GB/T 16913.1-1997 粉尘物理实验方法第1部分：试样粉尘的采集中的相关规定。

原理

粉尘从漏斗口在一定高度自由落下充满量筒；测定松装状态下量筒内单位体积粉尘的质量，即粉尘堆积密度。

仪器结构

1、漏斗(流出口直径12.7 )

漏斗不锈钢材料制成，其中漏斗锥度为60°±0.5°。

2、测量架

不锈钢材质，用于在粉尘装入漏斗时防止粉尘下落。

3、天平（客户自备）

称量300g；精度0.01g。

4、量筒

本装置配备一只容积为100ml的不锈钢量筒，量筒内径为Φ39mm。

5、刮板

不锈钢材质，用于在粉尘装入漏斗时去除多余的粉尘。

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
