Storage bunker
Storage and dosing bunkers are components of the feeding technology . They are used to bunker (stockpile) larger amounts of bulk material and to feed them dosed to a downstream vibratory conveyor (see also vibratory spiral conveyor ). With them, the autonomy of a feeding device can be increased many times over.
Executions
Storage bunkers are available in different designs depending on the application and the material to be conveyed:
- Vibratory bunker
- Belt bunker
- Bias tape bunker
Drive variants
Vibratory bunkers consist of a welded bunker pan, which is driven by a linear vibratory conveyor and works on the micro throw principle. In other words, during the conveying process in the bunker trough, the conveyed material is repeatedly conveyed a little further and thereby performs a micro-throwing movement. Vibration bunkers with micro-throw technology are the most common systems on the market and are available with a filling volume of up to 300 liters.
Vibrating bunkers with low frequency drives are a special feature, as they work in the sliding conveyor process. In other words, the conveyed material no longer lifts off the conveying surface of the bunker pan during the conveying process, but glides forward with very little noise. Since the acceleration due to gravity is not exceeded, it is a very low-noise and gentle method of vibrating mass-produced parts. Vibration bunkers with slide conveyor technology are available with filling volumes of up to 750 liters and a load capacity of 2000 kg.
Belt bunkers and inclined belt bunkers are belt systems driven by an electric motor with an attached static bunker pan.
