PowderPro A1 – Automatic Powder Physical Characteristics Tester

The processing and manufacturing of powders and bulk materials requires a deep understanding of their mechanical and physical properties. The industry often faces problems such as powder jamming in hoppers, uneven filling of tablet presses or metal powder layering errors in additive manufacturing (3D printing) equipment. The cause of these problems is usually improper powder flow or unpredictable density changes during mechanical impact. The PowderPro A1 was designed as a unified, fully automated solution that allows a single instrument to measure the full range of powder properties that previously required several different hand-held instruments.

The main innovation of this device is the synergy of mechanical process and image analysis. When measuring parameters such as the angle of repose or angle of incidence, the PowderPro A1 uses an integrated high-resolution camera and specialized image recognition algorithms. When the powder falls onto a special platform and forms a cone, the system automatically takes a picture of the object and digitally draws the exact angle line. This completely eliminates the human factor, since in traditional methods the laboratory technician measured the angle with a manual protractor, which led to large differences in results between different workers.

The device uses patented rotary vibration technology to determine density parameters. When measuring tapped density (Tapped Density), a special cylinder platform performs precisely calibrated impact and rotational movements, ensuring uniform compaction of the powder without the formation of air gaps. The device automatically records the initial and final powder volume and weight, and the software instantly calculates the bulk density, tapped density, Hausner ratio and Carr index. These indicators allow production engineers to know in advance whether the powder will easily fall apart into production forms, whether it is prone to jamming and requires additional flow additives.

Another unique feature of the PowderPro A1 is its dispersibility measurement. The device can assess how a powder behaves when falling through the air from a certain height – whether it maintains a continuous flow or forms a dust cloud. This is especially relevant in the chemical and building materials industries, where powder dustiness is directly related to worker safety and raw material losses during production. All the data obtained is combined into a detailed report, and the software automatically classifies the powder flowability according to the Carr scale from very good to extremely poor.

The device is designed for extreme robustness and ease of cleaning. All parts in contact with the sample are made of the highest quality stainless steel, and an integrated dust extraction port allows the connection of a laboratory pump to ensure a clean working environment. The device fully complies with strict pharmaceutical standards, including USP Section 616 and the requirements of the European Pharmacopoeia, so the data obtained can be directly used in pharmaceutical quality control certificates.
