Genron Vehicle Recently, Genron exported 10 pcs bulk carrier cement tankers trailers to the Manila port of Philippine. We got good feedback from our clients in Philippine. We export bulk cement tanker carriers from Year 2012, have rich experience. The semi-trailer for transporting powder and granular materials is a special vehicle for transporting large quantities of dust materials (bulk cement). It uses its own engine power to drive the on-board air compressor through the power take-off, and sends compressed air into the air chamber at the bottom of the sealed tank body, so that cement becomes fluidized. When pressure reaches the rated value, the unloading butterfly valve is opened and cement flows through pipeline for transportation.
