Weigh belt feeders are relatively simple, extremely reliable feeders providing high feeding precision and efficient process monitoring. They can be used as a feeder, batcher, or even as a meter.
AAG Engineering is the manufacturer of Weigh belt feeders. Our belt weigh feeders can handle capacity ranging from“0.054 tons/hr to 2500 tons/hr”. The accuracy our feeders can deliver is +/-0.25% to 0.5%.
Here is the brief description of the design of AAG Engineering’s weigh belt feeder
The principal design of the weigh belt feeder:
The upper side of the weigh belt feeder is divided namely into three zones. The first loading zone, which in most applications is provided with a hopper. The second zone lies below the first zone where a load plate is situated. The next zone is the weighing area under which a weighing plate is situated. The third zone is the feed out part at the end of the belt.
There are series of hole alongside the belt. Between the loading and weighing zones are toothed drive wheels. These teeth drive both the upper and return strands of the belt. This upper and return strand driven belt help in preventing from sideways travel.
The material is drawn out from the hopper and is delivered to the weighing zone where the belt tension is negligible. The roller at the output end is spring mounted to give a small controlled belt tension.
Brief overview of construction of belt weigh feeder
Basically, the weigh feeder consists of two main part – the conveyer and the stand.
The conveyor has a frame with two transverse tubes. These tubes slide on shafts attached to the frame of the stand. Also on the stand is the drive gear.
The toothed wheels are driven from the inner side via a joint coupling, making the conveyor frame easily withdrawn for cleaning. Along the belt, sides are adjustable side skirts.
At the drive, wheels are devices for pressing the belt against the driving teeth. The side skirts are removed sideways if the belt requires replacing.
Belt scrapers for both sides of the belt are situated at the output end. These are V-shaped and placed in front of each other. The lower one is part of a cradle construction formed as a weight loaded tilt (collecting) plate from which the waste falls at the output end.
Before the belt is removed the complete scraper device is easily lifted off its pivots and removed. Also, the waste from the inside of the belt is discharged onto the tilted collecting plate
Applications of Belt weigh feeder
The weigh belt feeder is intended for feed out and dosing of bulk materials such as powder and granulates. The material is drawn out from a bin situated above the weigh feeder and the feed rate is controlled by changing the belt speed. By using different software in the instrumentation a constant feed rate – or ratio control could be obtained.
We at AAG have a vast experience in belt weigh feeders. We ourselves do the design to meet the specific needs of an application by working closely with our customer. We manufacture to ensure accurate weighing and minimal material wastage to the customer expectations.
