What is a linear weigher?
It is an automatic weighing machine that consists of several key components, including storage hopper, vibrating feeder lane, and weigh bucket. These components work together to provide accurate measurements of granular, powdered, or free-flowing products.
How does linear weighing machine work?
Vibrating feeder lanes feed products from storage bucket to weigh buckets, the weigh bucekets which are connected with loadcell weigh the weight as preset parameter. While the weight of weigh bucket reaches 80% of desired weight, the vibrating feeder lanes will lower down the vibration, lower down the feeding speed for high accuracy weight.
What are the linear weighing machine application?
Linear weighing machine scales are commonly used in various industries for small sizes products, such as seeds, rice, granular powders, small snacks, berries, small pet food and so on.
What are the common models of linear scale?
Here is the worksheet and datasheet of our 1 to 4 heads linear weighing machine.
