Automatic Blaine Air Permeability Apparatus

Automatic Blaine Air Permeability Apparatus is a professional system designed to determine the specific surface area (Blaine fineness) of cement, lime, and other fine binders in a fully automatic and reproducible manner. The microcomputer-controlled unit automatically manages vacuum levels, timing, and result calculations, minimizing operator influence and ensuring consistent results in high-throughput production. The stainless-steel Blaine cell, complete with disk and plunger, maintains stable packing density due to its leak-proof and rigid construction. An integrated temperature probe automatically applies viscosity and temperature corrections according to ambient conditions. The high-resolution digital readout and large-screen interface provide workflow-accelerating functions such as one-touch test initiation, calibration with reference material, and automatic averaging. An optional dual-measurement station allows two specimens to be processed consecutively, increasing efficiency. Internal memory, USB/CSV data output, and software integration enhance traceability of quality records. The apparatus is designed for intensive laboratory use, featuring low-maintenance smooth surfaces, solvent- and temperature-resistant seals, and a compact, quiet vacuum module. The system architecture is developed to meet the dimensional accuracy, speed, and timing control criteria specified in ASTM C204, EN 196-6, and AASHTO T153 standards, ensuring reliable and reportable results for production quality control, acceptance testing, and R&D studies. In summary, the Automatic Blaine Air Permeability Apparatus combines automation, precision, and user-friendly design on a single platform, making cement fineness measurement fast, safe, and cost-effective.
