One of the strengths of P.R.T.
Service & Innovation production, these machines are characterised by
their ease of use.
Hot granulation of thermoplastic
material is carried out directly on the extrusion surface, made up
of a die with several holes, which a blade cutting device works on.
This device is particular because
it is capable of varying and regulating the contact pressure of the
blades on the surface of the die, even during operation.
The granulator with horizontal
axis offers the advantage of a non-deviated flow of the melted
material between the extruder and the die, with a consequent
reduction in the loss of pressure at equal capacity, and elimination
of the stagnation points of the finished product.
Internal cleaning is easier,
quicker and more effective, above all when frequent changes of the
type or colour of the material to granulate are necessary,
noticeably reducing the quantity lost.
Once cut, the granule is
immediately cooled inside a cylindrical chamber, using a flow of
water or air.
Water working:
The water and the material go
through a conveyor and are separated before entering the vertical
drying centrifuge.
The material is expelled through
an unloading cyclone, on which a fan for the extraction of humid air
generated inside the centrifuge and a flow sensor can be installed
respectively.
The centrifuge and the cyclone are
soundproofed to respect the noise limits permitted by current
regulations.
All the parts of this machine
which come into contact with water are made of stainless steel.
The mounting of a suitable
water-water heat exchanger on the machine allows the user to
maintain a suitable temperature for cooling the granules on the
basis of the capacity required.
Air working:
Once cut, the material is transported and cooled by
air flow along a given pipe and discharged at the exit of a cyclone
which increases the contact time between material and air.
During this passage is lost about 80% of the heat possessed by the
material from the die exit.
