The line of granulation SLE-1-130 for PVD, PND, polypropylene

Structure of the line:

1. Plastkompaktor CONDUSCV-400

2. Tape LTR-300 conveyor

3. SLE 1-130 extruder

4. Vacuum decontamination

5. Water ring cutting of SL-TR-80

This technological line is intended for processing of such types of raw materials

as PVD, PND and polypropylene. The line is completely automated.

Productivity on these types of raw materials reaches up to 400 kg/h. In final

result you receive a qualitative granule.

Plastkompaktor is intended for consolidation of all types film and woven

waste of polymers (Polypropylene, PND, PND, PS and other) to a state suitable

for the subsequent granulation, extrusion, molding under pressure.

Thanks to effective process of processing you receive well loose,

with a high bulk density a product at the minimum energy consumption from high

productivity.

Process of a kapsulyation happens to the minimum thermal loading on

material, formation of a capsule of any of plastic occurs at

to temperature melting points due to frictional heat are lower.

Advantages:

 A production continuity, it is possible to build in in

technological line

 There are no quickly worn out knots

 At the exit well loose is kapsulit, it is not dependent on qualification degree

expert

 Completely there is no material overheat (thermodestruction)

 At humidity of initial material does not decrease to 10%

productivity

 Low energy consumption

 Unloading of raw materials is continuous, automatically without use of unloading

devices

 Ease and low costs of maintenance

Material continuously moves in a zone of loading of a plastkompaktor, getting on

the rotating rollers material mechanically is condensed and pressed through through

the forming matrix. Thereby it turns out loose swore from high

bulk density.

The tape conveyor – the batcher

it is intended for the dosed giving

raw materials (plastkompakt, agglomerate,

drablenka) in a zone of loading of an extruder.

Material is filled up from the plastkompaktor bunker in the loading bunker

the conveyor and further moves on the conveyor tape equipped

gofraborty and inclined shovels, to a zone of supply of material in an extruder.

the volume of the given raw materials is regulated by means of change of speed of a tape

(the frequency converter) or change of a cycle of giving (timer) in

dependences on requirements of the customer.

The extruder of SLE-1-130 is intended for receiving uniform fusion from

the crushed, or agglomerated plastic raw materials and further

processings through the strengovy head, from the subsequent cutting on granules in strengovy

granulator.

The extruder can be equipped with the batcher for "pushonka" which allows to give in

loading zone raw materials of low bulk density (shredded film).

It is made with 2 decontaminations.

The lubrication system is karterny

Polymeric material is loaded into the batcher of an extruder which evenly doses

supply of material in a loading zone. The size of giving of raw materials remains to a constant, or

it is regulated by means of change of speed of rotation of the screw by means of frequency

converter. Getting to an extruder material moves on the material cylinder,

it is taken the rotating screw and transported to the strengovy head. For

providing the required thermal mode on the material cylinder are established

zonal ring heaters with individual ventilating devices; for

control of temperature thermocouples serve. The screw receives rotation from

the electromechanical drive consisting of the electric motor of alternating current and

the reducing mechanical transfer. The axial effort operating on the screw in

the direction opposite to fusion transportation, it is perceived

in bearing knot.

Vacuum decontamination is intended for

removals of moisture and the burned-out impurity from

fusion.

Advantages

 More effective way of removal of moisture and the burned-out impurity not only with

surfaces of polymers, but also at all depth of fusion

 Increase in productivity

 Improvement of quality of raw materials at the exit

 Installation of an additional extract over decontamination is not required

 Reduces machine pulsation level

Hot face cutting

It is applied as the device to formation

thermoplastic weight in granulate

The final product is the granule of 2-4 mm.

 allows to reduce length significantly

 to change quantity of technological

 will allow to avoid negative influences

strengovy granulation.

The melted plastic comes out through openings dies and is cut off

the fast-rotating knives. These granules are rejected by centrifugal force to

to casing walls where water supply creates a water ring. Water together with a granule

moves on a vibrosieve. On a vibrosieve the part of water from granules beats off and leaves through

perforation in a bathtub. Other part of water evaporates internal heat of a granule. In

the end of a vibrosieve the granule fails through large perforation to a mouth

rashes. The granule gets enough sleep either in the reception container or in the bunker

pneumotransport (if it is necessary to transport it in the bunker the store of bigger volume;

or the granule needs additional dehumidification). Water the store passes in a bathtub

on compartments where separates from large pollution. If necessary water or

heats up by means of TENOV, or it is cooled by an additive of cold water, and moves

in the pump. Water is pumped by the pump in a water casing of the face head
