HAVER filling system with vertical impellerFully automatic HAVER valve-bag filling machine with valve closing and automatic bag applicator4

HAVER vertical filling impellerHAVER valve-bag fillingmachines using the verticalimpeller filling system is ahighly successful technology for filling loose, powder-type, bulk material intovalve-bags according to thegross weight system.Cross-sectional view of a HAVER valve-bag filling machine with the vertical impeller filling system andautomatic, vertical bag dischargeThe advantages production rate of up to350 bags / hour perfilling spout precise weighing duringthe filling process high compaction levels low aeration amountduring filling produceshigh density packaging minimal spillage rapid emptying of thepacking silo and fillingmachine via a second(optional) impeller outlet easy accessibility foreffective maintenanceand cleaning modern drive systemdesign and optimallydesigned wear-partsassure maximum plantoperation time maximum adaptation todifferent productproperties and bagsizes through optionalvariability5

HAVER valve-bag filling machine with horizontal impeller filling systemThrough continuousdevelopment, HAVER’shorizontal impeller filling machine is designedto pack highly flow-resistant, powder-type, loosematerials that are proneto clogging.Features especially adaptable todifferent materials andmaterial flow characteristics large material inletcross section high filling speeds continuous materialfeeding (no clogging,no bridging) high filling speedswhile maintaining tightweight tolerancesHAVER valve-bag filling machinewith the horizontal impeller filling systemHAVER horizontal impeller6Cross-sectional view of a HAVER valve-bag machinefilling with the horizontal impeller filling system

HAVER air entrainment system - variant IThe air entrainment machineaccording to the gross weightfilling system is used for fillingfree flowing materials as well astechnically difficult powder-typeand granular products.The pressure chamber aerationconcept provides optimum productflow with minimal air consumption.Aeration rates depend on theproduct characteristics and areindividually adjustable.Thanks to continuous suctionduring filling, high filling rateswith minimum internal bagpressure are assured.Pressure chamber with inclined bottomAir entrainment packing machine for manual operationOpened pressure chamber allows easy and rapid cleaning7

HAVER air entrainment system - variant IIThe universal air entrainment system has gainedwide acceptance for fillingfine to granular productsinto valve-bags. The idealarea of application is thepacking of products thatconsist of a mixture of fineand coarse particles.Inline filling machines areavailable for manual orfully automatic operationand for integration into existing packing plants withup to four filling spouts.Advantages gentle product handling material components donot become separatedduring the packing process production rates of up to400 bags / hour per fillingspout high weight precision fully aerated pressurechamberHAVER valve-bag filling machine using the air entrainment systemoutfitted with an automatic vertical bag discharger8Cone valve(opened / closed)

HAVER bag chair variants12Bag chairs for manual removal,manually height adjustableBag chairs for automatic,vertical bag discharge - manually adjustableBag chair for automatic verticalbag discharge, motorized,stepless height adjustment viabag-type pre-selectionFor machines with the manualremoval of filled bag, the bag chairmay be adjusted to suit the lengthof the bag using just a few motionsof the hand.When only one bag size is used orwhen bag changeovers are seldom,then the tip-chair for automaticdischarge may be height-adjustedusing standard tools.For different bag lengths and frequent sort changes, the automaticbag chair height adjustment(through a gear reduction motorand spindle) is recommended.Adjustment is done simply by asort-selection key during productor bag changeovers.

HAVER ultrasonic bag closing systemThe optimized bag closingsystem using the HAVERultrasonic process prevents unwanted materialleakage from the bagvalve, assures cleanly filled bags and subsequentlyimproves storage andhandling of filled bags.After filling, the valvebag is moved away in thestanding position. Theultrasonic closing headthen pneumatically swivels downward and weldsthe plastic or plastic coated paper valve shut.Special advantages secure closure, evenwhen the valves areaffected by the materialinside self-cleaning effect ofthe weld zone by theultrasonic system short cycle times - highhourly production rates parallelogram transfersystem for moving thefilled bag away fromthe filling spout all standard valve sizescan be closed heating occurs only inthe weld zone valve position sensorsfor activating the ultrasonic generator reliable, low maintenance technologyHAVER valve-bag filling machinewith ultrasonic closing unitUltrasonic valve-bag closing unit14A securely closed valveCleanliness - the result of tightly closedbag valves
