Because of the reason of using rectangle type aggregate bunker (2×2) in the mobile concrete batching plants, it must be needed to build two side ramp for loading aggregate material. As is known, the best advantage of mobile concrete batching plants is easy transportation from worksite to worksite. However, because it is not possible to move the built ramp for other worksite, it must be needed to build a new ramp in the new worksite. It means extra costs. In this case, Semix solves this kind of problems with using Aggregate Pre-Feeding System. Optional this unit, can be added to Mobile Concrete Batching System according to customers’ demands. In the pre-feeding system; aggregate pre-feeding system, loading bunker, transfer belt, rotational chute and integrated structure to control panel can be used from the control cabinnet without extra effort. Aggregate Pre-Feeding system provides effectively and easy aggregte material loading, alongside of not having building ramp costs. This production can be produced according to customers’ demands in two types as mobile and stationary.
