Weigher checks up to 16 packages simultaneously
Advanced and efficient checkweigher - drag chain style scale - is capable of weighing, classifying, and rejecting up to 16 items simultaneously for quality control in packaging.
A pneumatically operated heavy-duty reject ram is located directly off the side of the weigh station conveyor to quickly and accurately reject all off-spec packages.

An optional reject accumulation tray or conveyor can be located on the opposite side to collect rejected items.
The benefits this in-motion checkweigher provides can make a big difference to a production facility.
The fact that it has the capability to reject large bags right on the scale itself provides rejection capabilities for many production lines that may not have room for a rejection system.
Since it weighs and rejects all in one, the checkweigher costs less than a standard scale that would otherwise have a separate conveyor with the rejector installed on it.
Installing the system is also much less obtrusive to existing production lines.
This checkweigher is a simple, easy to use, rugged, yet highly accurate production scale.
Although the 4693-R Checkweigher is specifically designed for harsh, abusive, dirty environments commonly found in the cement, concrete, soil, and bark industries; it remains extremely accurate and dependable.

Items compatible with the 4693-R include anything from bagged product, to boxes, cartons, and pails.
A variety of weigh station conveyors are available to meet the specific needs of each application.
