Blaine Fineness Air Permeability Apparatus
- Product Description
Air Permeability Apparatus
Used to determine the particle size of Portland cement, limes and similar powders expressed in terms of their specific surface. It consists of a stainless steel cell, perforated disc and plunger. An U-tube glass manometer is fit to the steel stand. The set is supplied complete with rubber aspirator, pack of filter paper and thermometer.
Automatic Blaine Apparatus: What It Is and What It Can Do for You
What is an automatic Blaine apparatus? It is one of the tools that are well-utilized in the cement industry. If you are wondering what it is and how it can help your enterprise, then this short guide might prove useful to you.
The different types of standardized fineness tests will also be discussed to a certain degree. This will help to highlight why a Blaine apparatus is beneficial and what other tests you may need to include in your operations and processes.
What Is an Automatic Blaine Apparatus?
An automatic Blaine apparatus is a piece of equipment that is used to measure how fine powdery products are such as cement. The fineness is measured and expressed as total surface area in square centimeters per gram.
SZB-9 Full Automatic Cement Blaine Fineness
According to the new standard of GB/T8074-2008,together with national building materials research institution,new material is institution ,and quality supervision ,examination and test center for instrument and equipment,our company has developed new SZB-9 type full -automatic tester for specific area. The tester is controlled by single-ship microcomputer and operated by light touch key.
The tester can automatically manage the whole measuring process and automatically record the value of tester.The product can display directly the value of specific area and record the value and test time automatically.
The apparatus is used for determining the Fineness Of Cement in terms of specific surface expressed as total surface area in square centimeters per gram of cement.
Working principle:
ASTM204-80 air permeability method
1. The specific surface area of cement refers to the total surface area of cement powder per unit mass.
2. When a certain amount of air passes through a cement layer with a certain porosity and a fixed thickness, the specific surface area is determined by the change of the flow rate caused by the different resistance.
