Brabender® Auto-Grader® Continuous In-Line Melt Index and Film Quality Analyzer … where quality is measured

Automatic In-Line Quality Control Features, application area Your laboratory on the production site The Brabender Auto-Grader continuously determines the quality characteristics (typically: MFI, MVR, optical properties) relevant to production practice. The complete machine control as well as the representation of the measured results are done fully automatically and continuously within seconds. The Auto-Grader can be integrated in-line into a pellet conveying system or in bypass to a production extruder. Principle The standard Auto-Grader combines two different measuring systems: Due to the...

Powerful software In a production environment, (e.g. in continuous polyolefine synthesis), each production line can be monitored automatically by an Auto-Grader. All evaluation results, alarms, user actions, and control values of each Auto-Grader system are collected and stored in a central database. The evaluation results are memorized continuously together with the corresponding time. Rheological values: • MFI (MFR) • Consistency factor • Flow exponent • Shear rates • Shear stresses Optical values: • Degree of transparency in % • Gels and black specks detected • Each in up to 9 size...

Alarm table System diagnosis During continuous operation, alarms in case of malfunctions or anomalies are essential. Therefore, all alarms are handled in a special alarm table which is part of the database. A diagnostic routine is run each time the system is started. The monitor shows each individual step of this system check. These alarms are displayed and stored in detail together with the type of fault, time, actual value, and limit value. Some of the hardware alarms lead to automatic system corrections. Dimensions (W x H x D) 1900 x 1800 x 1000 mm (incl. monitor) Weight approx. 620 kg...
