Through their continuousdevelopment, the HAVERvertical impeller fillingsystem RS could be opti-mally designed to fulfillthe special requirementsof filling free-flowing,bulk materials – especial-ly for building materialsof every type.

The results:

• optimum filling effi-ciency for small bagdimensions with mini-mum aeration

• reduced wear and tear• high operational safety

levels• quick and easy access

to exposed parts suchas the turbine impeller

• filling pressures that areoptimally transmittedvia specially designedfilling channels

• pneumatically operatedslide valve coarse-,fine flow and shut-offof filling

• soft-start drive systemusing V-belts

Cross sectional view of a HAVER type RLE ROTO-PACKER – air type filling system

The HAVER ROTO-PACKER series RL desig-nates a rotating valve-typebag filling machine (with3, 4, 6, 8, 10 or 12 spouts)according to the air typefilling system. The area ofapplication includes pow-der type, fine or coarsegrain, flow resitant prod-ucts or mixtures with fineand coarse components,granulates, crystals orgoods of similar particles.

The average operationaloutput using paper andplastic bags with interiorvalves is between 900bags/hr. with 3 fillingspouts, and 4000 bags/hr.with 12 filling spouts.

By combining the ROTO-PACKER with the HAVERRADIMAT automatic bagapplicators (bundle or reelsystem), fully automaticoperation is possible.

Whenever filling buildingproducts and fine mineral-based materials, theROTOSEALpackingplants developed byHAVER & BOECKERwill certainly convinceyou when it comes tooperation and economics.Clean operation and exactweight filling as well as anoutput of up to 3000 bags/hr. are the dis-tinctive characteristics ofHAVER packing systems.

ROTOSEAL®-PACKERs–designed according to theimpeller type filling sys-tem or air type filling sys-tem – require no subse-quent bag cleaning sys-tems or dedusting equip-ment for producing cleanfilled bags.With ROTOSEAL®,absolute cleanlinessduring packing operationis standard.

• compact modular con-struction in a completeup-to-date design thatincludes integratedautomatic bag placingsystem, control paneland control cabinet

• partially transparentcover panels assureideal equipment view-ing as well as easieradjustment and mainte-nance work

• compact spillage returnsystem design – a basiccost savings, and notonly in plant costs

• reduced installation andcommissioning workdue to its modulardesign. Control networkwiring is done withease using plug-typeconnector systems

Technologically, thefuture has already begunat HAVER & BOECKER.Expandable with up to amaximum of 12 fillingstations, the ROTOSEAL®

machines of the new cen-tury are characterized bythe following features:

The cone valve may beused as an alternative tothe rotary feeder whenloads from product in theinitial silo are notexcessive.

The cone valve ispositioned in the ROTO-PACKER inlet. Itsactivation is donepneumatically and anuncontrolled opening isprevented by a mechani-cal lock.

The HAVER verticaldouble rotary feeder canbe used any place wherepowder type, free-flow-ing material must bevolumetrically fed withconsistency.

Impeller sectors, sealedon all sides, rotate abouta vertical axis. Thematerial flow is therebyforced and the materialcannot simply dropthrough. The sealingstrips are adjustable andreplaceable, if necessary.

Power transmissionoccurs via a flat bevelgear unit driven by anAC motor and drivebelts. An adjustabledrive unit may be usedas well.

The HAVER air type fill-ing system (photos 3 and4) offers the followingfeatures:

• pressure chamber withcone inlet valve assuresuniform product feed-ing without the compo-nents of the product toseparate.

• removable bottom plateof filling box for easycleaning and mainte-nance

• closed, dust-free fillingchannel with pinchvalve

• distribution of convey-ing air using multipleaeration pads, allowshomogeneousproduct/air mixture(this results in reducedair quantities, lowerpressures)

HAVER vertical fillingimpellers (photos 1 and2) are characterized by:

• high compaction levelsthrough minimized airentry

• speed variability, beltdrive system

• air feed controldepends on the fillingspeed

• ring gap aeration tominimize wall frictionbetween the filling tubeand product

• minimal air consump-tion

• impeller drive unit isoutside the area of con-tamination

• easy accessibility formaintenance and clean-ing

• compact bags• minimal spillage

HAVER filling shutoffvalves – as slide gatevalve or pinch valve arealways functional andreliable over the longterm.

Advantages:

• high weight accuracyby exact material flowdosing

• 3-position cylinder forfull and fine flow

• manual or motorizedadjustment of fine flowopening

• extremely low productadhesion

• optimum interactionbetween weighing partsand stationary parts

• air tight closing offilling channel

• tried and provensystem, even underextreme conditions

Among other aspects, thespillage rejecting flapoffers a big improvementin bag cleanliness.During discharge, therejecting flap preventsthe bag from becomingcontaminated withproduct that could dripout of the filling tube.Activation of the rubberflap occurs pneumatical-ly.

As an automated systemfor the ROTO-PACKER,the HAVER RADIMATvalve type bag applicatorrepresents a significantpotential for plant ratio-nalization:

General advantages:

• modular design• standardized for a wide

range of bag types• automatic adjustment

for varying bag sizes• self adjustment with

respect to the ROTO-PACKER rotary speed

Minimized machinedown times are the directresult of the RADIMAT’suse of a tried and proven,low maintenance, drive system.

Other decisive factorswith respect to produc-tivity include the SPScontrolled processes anda bag feeding reliabilitythat doesn’t adverselyaffect the subsequentfilling system.

This allows the use oflarge diameter fillingtubes for achieving:

• high filling speeds• excellent weight

accuracies• exceptional bag

cleanliness

The work operations andfunctional steps togetherwith a HAVER ROTO-PACKER allow fillingrates of more than 4000 bags/hr.
