Moisture and mass flow in the bulk industry

Moisture and mass flow on the conveyor belt

Accurate information on bulk flow and moisture content is essential for efficient material handling, reliable process control and consistent product quality. Berthold’s combined measurement solution determines both parameters continuously and in real time directly on the conveyor belt. Radiometric technology provides reliable bulk flow measurement, while microwave technology with horn antennas determines the moisture content of the conveyed material. Both measurements are contactless and can be easily integrated into existing conveyor systems.

Typical applications for bulk flow and moisture

Recycling industry, e.g. plastic domestic waste
Agrar industry for example NPK fertiliser
Mining industry, e.g. concentrated apatite rock or sulfur extraction
Food industry, e.g. bagasse processing after sugar extraction
Construction industry, e.g. gypsum (phosphoric co-product/residuum)

The measuring principles

Radiometric bulk flow measurement with detectors

Reliable online monitoring on all conveyor systems, even where conventional methods cannot be used
Reliable adherence to delivery/production quantities
Optimal utilization of storage capacities
Optimal addition of raw materials in mixing processes hence, very fast amortization of the measurement
No recalibration or cleaning necessary

Microwave moisture measurement with horn antennas

Known moisture content when tendering / loading of bulk material ensures consistently high quality of the products
Multifrequency technology for dynamic plausibility control of the raw signal
Easy installation, also on already existing conveyor
systems
Wear-resistant and maintenance-free due to contactless measurement
Reliable long-term measurement without recalibration
