三,水泥勃氏透气比表面积仪工作原理:
★采用高可靠单片机和集成电路,软、硬件采用多种抗干扰技术,现已在全国各地得到广泛应用。为了提高水泥行业试验室自动检测水平,减少人为误差,我们开发出自动比表面积测定仪(勃式法)。
★水泥比表面积指单位质量的水泥粉末所具有的总表面积。
★用一定量的空气通过一定空隙率和固定厚度的水泥层时,所受阻力不同而引起流速的变化来测定其比表面积。
★根据一定量的空气,通过具有一定空隙率和一定厚度的水泥层时,所受阻力不同而引起流速的变化来测定水泥的比表面积。在一定空隙的大小和数量是颗粒尺寸的函数,同时也决定了通过水泥层的气流速度。
★如何控制FBT-5水泥勃氏比表面积:
一般用钢球级配,选粉机转速,台时产量来调整水泥的细度和比表面积。钢球级配应是*关键的一环,合理的级配对降耗和质量都有好处。可以在磨机检修时,在磨内分仓分段取几个点,做细度比表面积,做成工作曲线,供自己参考,选取合适的球配。当然,这要和熟料.混合材等原材料的变化而变化。  按LZ的说法,单独生产一批水泥,是比较麻烦。
Third, the working principle:
★Using high-reliability single-chip microcomputer and integrated circuit, the software and hardware adopt various anti-interference technologies, and have been widely used in all parts of the country. In order to improve the automatic detection level of the cement industry laboratory and reduce human error, we have developed an automatic specific surface area measuring instrument (Beauty Method).
★ Cement specific surface area refers to the total surface area of cement powder per unit mass.
★ When a certain amount of air is passed through a certain void ratio and a fixed thickness of the cement layer, the specific surface area is determined by the difference in the flow rate caused by the difference in the resistance.
★ According to a certain amount of air, when the cement layer has a certain void ratio and a certain thickness, the specific surface area of the cement is determined by the difference in the flow rate caused by the difference in the resistance. The size and number of voids in a given volume is a function of particle size and also determines the gas flow rate through the cement layer.
★ How to control the specific surface area of FBT-5 cement:
Generally, the steel ball is graded, the speed of the powder is selected, and the output is adjusted to adjust the fineness and specific surface area of the cement. Steel ball grading should be the most critical part, and reasonable level matching is beneficial to both consumption and quality. When the mill is overhauled, take a few points in the grinding machine to make a fine specific surface area, and make a working curve for your own reference, select the appropriate ball. Of course, this will change with changes in raw materials such as clinker and mixed materials. According to LZ, it is more troublesome to produce a batch of cement separately.

四,水泥勃氏透气比表面积仪维护和保养
1、对FBT-5水泥勃氏比表面积仪,水泥比表面积仪,水泥勃氏比表面积仪,比表面积测定仪要经常擦拭,保持清洁,不用时应装入盒内备用。
2、压力计中液面应保持规定高度。
3、试验结束后将圆筒及穿孔板擦净,放入附件盒内备用。
4、试验前应注意检查电磁泵是否转动正常,负压要事前调整防止误将液体吸入电磁泵内。如已吸收液体,应将电磁泵空转一段时间,等液体自然排净后再使用权用。
ourth, maintenance and maintenance
1. For FBT-5 cement Boehmite specific surface area meter, cement specific surface area meter, cement Boehmite specific surface area meter, specific surface area measuring instrument should be wiped frequently, keep clean, and should be put into the box for use when not in use.
2. The liquid level in the pressure gauge should be kept at the specified height.
3. After the test is finished, wipe the cylinder and perforated plate and put them into the accessory box for use.
4. Before the test, please pay attention to check whether the electromagnetic pump rotates normally. The negative pressure should be adjusted beforehand to prevent the liquid from being sucked into the electromagnetic pump by mistake. If the liquid has been absorbed, the electromagnetic pump should be idling for a period of time, and the liquid should be used after it is naturally drained.
