SITRANS WW500 is a heavy duty high-capacity apron weighfeeder used for extremely harsh applications.

SITRANS WW500 is designed for industrial applications such as cement, steel, and other heavy-duty industries that convey clinker, granulated blast furnace slag or petroleum coke.

Robust heavy duty components ensure a long life of reliable feeding and control. Field tested and proven in hundreds of applications, it enhances profitability by ensuring accuracy, reducing downtime, and improving accountability and record keeping.

The unique weigh system reduces dead load and applies live load directly to load cells for accurate measurement, without the use of check rods, pivots or bearings. The four load cells are mounted below the apron pans to ensure protection and help with heat dissapation.

It is available in a variety of lengths to suit existing application requirements and apron widths up to 2 500 mm (98 inch), several different inlet configurations and materials of construction. It can be configured to suit various applications.
