Feeding of powdered materials
A mass flow-rate feeding/dosing device according to the Coriolis principle
MULTICOR® S mass flow-rate feeding devices are used wherever large amounts of bulk solids need to be continuously established, controlled and fed. They provide precise feeding according to the Coriolis principle, a unique measuring principle for bulk solids based on direct, fast measured value acquisition.
The active principle of the Coriolis force, in short
The bulk solids hit a rotating measuring wheel. Due to the centrifugal force, the bulk solid particles on the vane are moved outwards. On the measuring wheel – due to the acceleration in the direction of the circumference – the bulk solids are subject to the Coriolis force. This can be recorded as a measurable variable which is proportional to the gravimetric feed rate, even with changing bulk density or different grain size.
The performance is remarkable: MULTICOR® S from Schenck Process measures the material stream with an accuracy of ±0.5%. It is precise and very economical, whether it is used for dust, throughput and consumption measurement for in-plant inventory, polymer feeding in granulating plants (extruder feeding), charging of materials in a process, or optimisation of truck loading.
With MULTICOR® S, mass flows are exactly measured and fed in conjunction with an adjustable prefeeder, irrespective of the properties of the bulk solids. It is neither affected by nor sensitive to external influences.
It is simple to install due to its in-line implementation and compact construction. Maintenance and repair costs are both low.
