Knife Ring Flaker PZKR
PALLMANN Plast-Agglomerator PFV
100% Utilization of WoodWood is scare and expensive. Full utilization istherefore a must. We assist you with machines,especially built for the preparation of wastewood assortments. More than 5000 PALLMANNKnife Ring Flakers installed worldwide aresynonym for high flake quality, reliability,precision and durability. Due to constant furtherdevelopment of machines and material, we areagain and again resetting the standards inflaking technology.
Flake quality and constancy are the decisivedevelopment criteria.PALLMANN flakers are flexible and canindividually adapt to your flaking requirement.Professional chip preparation results in correctflakes for particleboards that meet any demand.

Method of OperationBy means of a feeding system, consisting of avibratory feed trough and a magnetic drum, thechips are transported into the flaking chamberthrough the gravity separator “Cleanomat” anda distribution system.The rotating turbo impeller accelerates the chipsand pushes them against the interior of the knifering where they are flaked by the knives installedtherein. The desired flake thickness is for themost part determined by the knife projection.The flakes are transported through a definedgap between knife and wear shoe and aredischarged vertically to below out of the machine.
The well-proven counter-rotating principleThe knife ring is chain-driven by a gear motorcounter-rotating to the impeller. This provencounter-rotating operating principle ofPALLMANN flakers assures uniform use of allknives and reliable discharge of the flakes.Theresult is a high cutting performance, constantflake quality and uniform wear.Furthermore, the counter-rotating principle ofthe knife ring ensures proper flake dischargeeven at extremely high moisture contents, i.e.no clogging of the flake channels and no materialaccumulation on the outside of the knife ring.

Constant flake quality - specifically set
Knife SettingThe knife packages, consisting of knife holdingplates and knives are, as a standard, set outsidethe machine in a setting device to the preciselydesired knife projection.When using a sharpening- and setting robot,type PZSE, the setting of the knives is performedfully automatically.
Setting of the beater platesThe simple and precise setting of the impellerbeater plates in the machines by means of afixture permanently ensures good flake quality.

Fighting wearEasily exchangeable, respectively re-grindablewear parts protect the interior of the knife ringand the turbo impeller. Good flake quality canalso be achieved in such a way over longerperiods of time.
Sharpening- and Setting robot PZSE- Fully automatic sharpening and setting of
the knives in the knife ring- Grinding of the wear shoes for optimum
knife projection- Control of wear tolerances of knives and
wear shoes- Optimum wet grinding process- Cleaning of grinding emulsion via band filter- Achievement of optimum knife cutting circle
and knife projection

Proven accessories
Gravity separator CLEANOMAT- Removal of foreign objects in accordance
with specific material density- Adjustable material- and air guiding flaps for
optimum adjustment to various feed materialsand operating conditions
- Cross current fan for the production of an even air stream over the entire material feeding width
- Increased operational lifetime of all wear parts
Cleaning of the knife ring- Automatic cleaning of the rotating knife ring
during the shutdown cycle- Optimum prerequisite for downstream knife
changing- Use of air or water for cleaning
Knife ring coding- Identification of all knife rings within one plant- Allocation of electronic data in the sharpening-
and setting robot

Constant flake quality
High throughput rate
Quick knife change
Precise knife setting
Optimum wear protection
No clogging at high moisture content
Economical in operation/maintenance
Robust, reliable and long lifetime
Proven installation
Optimum capacityKnife ring flakers should always be fed by meansof a vibratory feeding trough in order to achievecontinuous material feeding and optimumutilization of the installed electric force. Ourintegrated feeding system represents the idealsolution and consists of:- Vibratory feeder with coarse- and fines
discharge- Transition cover with integrated magnetic
drum separator for separation of ferrous contaminants
- Heavy gravity sifter “Cleanomat” for separation of stones and NE-metals etc.
The air produced by the knife ring flaker shouldbe dissipated by means of an exhaust systemwith integrated dust filter.
