MB-60M Mobile Concrete Batching Plants - MEKA Concrete Plants

Mobile Aggregate Feeding System. Due to the structure and design of mobile concrete batching plants aggregate bin height is quite high. In order to reduce the cost for building a one-side or two-side feeding ramp we have developed a mobile aggregate feeding system which allows easy aggregate feeding without any extra costs for foundation or ramp.
