areation with ring jet
Business Unit Building Materials and MineralsSeite 20
AERATION AND DE-AERATION DURING FILLING WITH VERTICAL IMPELLER
reduction of wall friction in the filling channel via minimized aeration by means of ring gap aeration
ring gap aeration prevents, that air is reaching the core of the product
amount of aeration is depending on the filling speed
this results in a clean filling process under high filling pressure and thus in a dense packing

ROTOPACKER 6 RLE
2 x Inline - Packer 3 LEV
Advantages of ROTO-Packer solutionagainst Inline-Packer solution
Business Unit Building Materials and MineralsSeite 28
lower investment and operating costs
less space requirement / building cost
only 1 product feedonly 1 discharge lineonly 1 spillage system
only 1 bag placer oronly 1operator for manual bag application
Business Unit Building Materials and MineralsSeite 29
higher output
no waiting time forbag placing due toconstant turning of packer(automatic / manual placing)
no waiting time for bagdischarge
Business Unit Building Materials and MineralsSeite 30
dust protection ofoperator / bag placer
the operator / bag placerstands outside of the fillingand bag discharge zone
Business Unit Building Materials and MineralsSeite 31
easier to palletizeor load on truck
due to constant bag streamand equal distance betweenthe bags
Business Unit Building Materials and MineralsSeite 32
highest flexibility for truck loading
higher capacity, no waiting timesno reduction during truck change
Business Unit Building Materials and MineralsSeite 33
manual purging
automatic purging 6 RLE
automatic product change
* Depends of the different length of the empty bags
critical product change-contamination not acceptable –
purge: T=23min.Moving of adjustment drives:
Tmax=0,5-3min. *Product change: ca. T=27-29min.
Residue emptying:T=2min. Discharge of
bags:T=1min.
Residue emptying:T=2min
Product change: ca. T= 6-8min.
Moving of adjustment drives:Tmax=0,5-3min. *
Purge incl. Flushing: T=3min.

Expansion
ROTO-Packers can be preparedfor later expansion :
e.g. a ROTO-Packer Type 8(4) RLE is equipped with 4 filling spouts in a first step
easy doubling of capacity while keeping theproduct feed, bag placer, discharge conveyor line...
