Dosing and weighing technology

Silo Weighers.

Low-maintenance weighing technology for free-flowing products. DoWaTec Silo Weighers operate without a conveyor belt and are particularly suited to free-flowing powders and abrasive bulk materials.

At a glance.

The product passes vertically through the weighing system and is weighed. As no conveyor belt is used, there is no belt wear. This makes the Silo Weigher particularly interesting for free-flowing and abrasive products.

Strongly clumping or non-free-flowing products are generally unsuitable for this principle. Specific suitability is assessed on the basis of product characteristics and process conditions.

Machine size and number of weighing lanes are selected to suit the product, target weight and process. The machine shown is an example configuration; customer-specific configurations are possible.

Tested bulk density range
0,5–1,5 kg/dm³ Confirmed technical specification Conditions: For free-flowing products; specific suitability is assessed for each product.
Number of weighing lanes
1-6 Lanes Confirmed technical specification Conditions: Designed to suit the required throughput and application.
Typical target weight range
approx. 100 g–20 kg Tested range Application-dependent value based on experience; not a general or contractual performance commitment. Conditions: Depends on the product, target weight, feeding, machine configuration and process conditions. The specific design is project-dependent; not a general performance commitment.
Cycle rate per weighing lane
approx. 5–20 weighings/min Typical value Application-dependent value based on experience; not a general or contractual performance commitment. Conditions: Depends on the product, target weight, feeding, machine configuration and process conditions. The specific design is project-dependent; not a general performance commitment.
Accuracy / weighing deviation
approx. 0,1–1 % of target weight Typical value Application-dependent value based on experience; not a general or contractual performance commitment. Reference: Respective target weight Conditions: The accuracy actually achievable depends on the target weight, product characteristics and the specific system configuration.

The achievable cycle rate and weighing deviation depend on the product, target weight, machine configuration and process conditions. The specific design is based on your requirements.
