Impact Detacher from MIAG Milling

Precision meets safety

Vibration monitoring for impact detachers

The VPAE impact detacher from MIAG is a versatile, high-performance machine specifically developed to break up flour flakes during the milling process. It can also be used as a standalone size-reduction machine to improve the efficiency and quality of the production process.

The product enters the machine either by gravity from above or by pneumatic suction from below. Inside, a rotating disc fitted with robust, bolted-on pins accelerates and breaks up the material. Additional pins attached to the stationary housing reinforce this effect and ensure uniform, thorough processing.

Centrifugal force carries the processed product outwards, where it leaves the machine through the tangential product outlet. It is then extracted by pneumatic suction and made available for further processing. This carefully designed construction ensures efficient and reliable size reduction that meets the requirements of modern production processes.

Monitoring objective

Flour production involves a constant risk of explosion, which largely depends on the concentration of the flour–air mixture. High-speed machinery poses a particular risk: malfunctions, such as imbalance, can create potential ignition sources in the form of sparks or overheated surfaces, leading to dangerous situations.

In addition, vibration monitoring enables continuous monitoring of machine condition, particularly the bearings. Maintenance and servicing can be initiated at an early stage to increase operational safety and prevent unplanned downtime.

ATEX requirements

In 95% of applications, ATEX-compliant sensors are required because most machines operate in potentially explosive atmospheres. For the remaining 5% of applications, where ATEX certification is not mandatory, MIAG nevertheless uses ATEX sensors exclusively. This strategy simplifies inventory management and installation, as there is no need to use different sensor types, while also ensuring consistent safety standards.

“With sensors from HAUBER-Elektronik, we can cover wide vibration ranges. These sensors also meet ATEX and SIL requirements. The broad product portfolio allows us to address individual customer requirements as well.”

Risks and preventive measures

Imbalance can result from caked-on product, rotor damage or problems with the machine bearings. It may develop gradually and worsen over time, or occur suddenly.

The vibration sensors from HAUBER-Elektronik continuously monitor machine vibration and detect deviations from normal vibration behaviour at an early stage. If the measured values exceed the specified limits, this indicates an imbalance. This can cause further machine damage; an exponential increase may also indicate severe damage. In such cases, it is essential to take the machine out of service immediately to prevent greater damage and safety risks.

Measurement parameters

The vibration velocity is measured in mm/s to monitor the machine’s vibration behaviour. Every machine has a specific baseline vibration level that is considered non-critical during normal operation. Exceeding the limits – depending on the absolute vibration velocity and its rate of increase – requires targeted action to prevent damage and safety risks.

Limit values

Limit values are set individually for each machine during commissioning, because normal vibration behaviour can vary with the machine and operating conditions. This tailored approach ensures precise and reliable monitoring.

Sensor placement

The sensor is mounted directly on the machine housing, oriented at 90° to the drive shaft. It is mounted using an M8 thread, and the electrical connection is made via an M12 connector. This position enables optimal vibration measurement and reliable monitoring of machine condition.
