Dynamic weighing machine

continuouselectronicfor bulk materials

Overview
Our continuous cellular wheel weighers are designed for measuring and recording mealy, powdery, fibrous and structured products. Load cells continuously measure the weight of the filled cellular wheel, providing an instantaneous weight of the varying product flow. Mealy, powdery, fibrous or structured products can be measured and/or weighed with an accuracy of ± 2%. The throughput capacity (depending on product and type series) is between 10 and 100 t/h or 20 and 300 m³/h. For protection against contamination and the resulting falsification of the measuring signal, the cells are cleaned regularly and at a freely selectable rhythm with compressed air.

Types and proportioning

• Three different machine types are manufactured to suit different bulk products and capacities.
• Proportioning is carried out using proportioning units of the types Simplex (200, 250 and 315) or Duplex (150, 200, 315 and 400).
• Proportioning is performed by low-pulsation proportioning screws; products are uniformly fed by drives with variable speed and screw configuration adapted to the product properties.

Design
The machine consists of a weighing frame with removable hood and inspection flaps; the cellular wheel made of special material serves as the weighing device. Continuous weighers are adapted to bulk product flows by constant speed and defined cell volume. Drives allow speed variation to adapt throughput to product characteristics.
