Working Principle: Deutschland

ZKS Vacuum Conveyor (or pneumatic conveyor) is the most reliable and economical conveying equipment for moving free-flowing powders, granules, pellets and other dry bulk materials by using pneumatic suction. The vacuum conveying system cosists of pick-up station, hose, vacuum receiver with filter, secondary filter and air pump. 

The air pump generates strong airstream which carries the bulk materials from the pick-up station to the receiving tank. Two types of vacuum coveyor are available:  

Type A: Feed to sealed tank / hopper. Insert the feed gun into the air-tight receiving tank, where solid material and air are separated due to different density. This design is commonly used to feed powder mixers or storage bins. 

Type B: Feed to open tank / hopper. Mount the vacuum receiver above the open receiving tank. The solid material is separated by tubular filters and then discharged via pneumatic flap valve. 

Technical Features:

• Simple and reliable design: The simple design make it easy for installation and maintenance. 
• Dust-free operation: The air-tight conveying system with two-stage filters (5 microns) makes the whole conveying process dust-free. 
• Easy to clean: The whole conveying system can be easily dismantled for cleaning. And the strong airstream can clean the system by itself. 
• Stainless steel tubular filter: The filter is made by stainless steel sintered mesh with minimum filtering size of 5 microns. 
• Feed hopper with different size and agitator or vibrator. 

Technical Parameters:

Note: The conveying capacity depends on raw material bulk density and particle size, conveying height and horizontal distance. The conveying capacity stated in the above table is measured with wheat flour and 4 meters long conveying pipe.
