Gravity feed

The product is conveyed to the weighing container by its own weight. In order to ensure regular and uniform flow, the product must be very free-flowing.

The main feed and fine feed can be adjusted using a cutoff gate with a variable opening that,depending on production capacity and the type of product being handled, can be driven pneumatically or via brushless motors.

The gravity-feed weighers manufactured by the Concetti Group permit excellent weighing precision thanks to all the mechanical features that have been adopted and the high-tech electronic control system that has been developed.

A control display dedicated to the weigher makes it possible to view the weighments and permits online adjustment of the weigher parameters.

The control electronics of the weigher can memorize up to 32 programs dedicated to different products that can be handled. As a result, the product change operations can be handled rapidly and when the system is part of a complete installation, this feature enables connection to other machines downstream as well as self-adjustments guided by the PLC.

The gravity-feed weighers manufactured by the Concetti Group comply with EC safety standards.
