負壓入料半密相氣力輸送系統負壓入料高密相輸送系統，具有較高的料氣比，較低的物料輸送速度，較大的輸送量，適用于粉狀、顆粒及磨蝕性物料；特有的方向負壓單個或多個入料閥門和底部出料方式，使用氣源壓力2-6bar。 DPV Conveyor Dense phase conveying equipment. Optimum material-to-air ratios and lowest convey line velocities and maximum convey rate. Applicable for powder, granular or pelletized or abrasive materials. Featured vacuum load via single or multiple material inlet valves from any direction(s), and bottom discharge for high rate. 2-6 Bar convey air source pressure負壓入料半密相氣力輸送系統
