The supply mechanism feeds the product to the drum container and fills it with the preset quantity.

The supply mechanism throttles gradually the product flow and terminates it with reached weight.

For discharging the drum container by is turned by a gear motor for 360 degrees. The container can be cleaned inside and outside. Thus the empty tare does not change.

Balancing range and capacity

The weighers are supplied for fillings between 10 and 600 kg. The capacity of the weuighers depends on the kind of the feeding equipment, on the bulk material weight and the fluidity of the product, on the discharge quantity and on the kind of the control.

With most products capacity is higher than 200 discharges per hour.

Construction

Construction was made especially for easy maintenance and dust free operation. That was realized a closed Steelhousing and an external controls- equipment.
