A unique adaptation of vacuum transfer is "direct blender loading," when a vacuum tight process vessel becomes the primary vacuum receiver for material being charged into it.
Direct blender loading offers major advantages over the manual charging of blenders, and also offers additional benefits over conventional conveying methods too.
A direct loading system offers greatly improved efficiency over the more commonly used method instead using the blender itself to pull a vacuum and draw the material from ground level. The direct loading method reduces the number of moving parts and improves efficiency by reducing convey times as the system operates on a continuous transfer. The conventional hopper is replaced with an inlet port on the blender, which the material charges into directly and continuously
