Air Permeability Specific Surface Apparatus Tester For Cement

SZB-9 Full Automatic Cement Blaine Fineness

Our company has developed a new SZB-9 type full-automatic tester for a particular area in accordance with the new standard of GB/T8074-2008, in collaboration with the national building materials research institution, new material is institution, and quality supervision, examination, and test center for instrument and equipment. A light touch key and a single-ship microprocessor run the tester.The tester has the ability to fully automate the measurement procedure and record the tester’s value.The product can automatically record the value and test time as well as immediately show the value of a specified location.

Using a specified surface area represented as the total surface area in square centimeters per gram of cement, the device is used to determine the fineness of cement.

Working principle:

Air permeability test ASTM204-80

1. The entire surface area of cement powder per unit mass is referred to as the specific surface area of cement.

2. The specific surface area is defined by the change in flow rate brought on by the various resistances when a particular volume of air travels through a cement layer with a specific porosity and a fixed thickness.Technical specifications:1.Power source: 220V at 10%2. Timing range: 0.1 to 999.9 seconds3. Timing accuracy: 0.2 seconds4.The accuracy of the measurement:15. The temperature range is 8 to 34 °C6. Specific surface area range: 0.1 to 9999.9 cm2/g7.Application range: within GB/T8074-2008′s defined range.
