PAS-420 acoustic cleaner prevents downtime for PET
A
Primasonics International product story

Primasonics has supplied an Acoustic Cleaner Model PAS-420 to PET to prevent cross-contamination during SSP production, in turn reducing product losses and downtime.
PET, owned by Diefenthal Investments, makes solid state polymers (SSPs) by enhancing the crystallinity and molecular weight for semi-crystalline thermoplastics.
These various products are produced in pellets and stored in an eight-tonne silo.
Unfortunately, cross contamination was occurring within the discharge cone section of the silo; this meant the silo had to be cleaned manually between different product types, causing loss of product and loss of production.
The most troublesome material was polyester pellets with a particle size of 2-3mm and a moisture content of 100ppm.
The material formed soft clumps that bridged over the silo outlet.
Alex Bergus, director of technology for Primasonics, visited the site to describe the benefits of installing a Primasonics acoustic cleaner just above the silo outlet.
Bergus said it would prevent material from building up in this hopper area without causing structural damage to the silo wall, as can be the case with vibrators or mechanical hammers.
Primasonics supplied an Acoustic Cleaner Model PAS-420 complete with external mounting tube and other accessories.
A small hole was cut on the side of the hopper discharge and the mounting tube welded in place.
The PAS-420 Acoustic Cleaner was bolted to the flanged end of the mounting tube and the accessory items put in place.
The acoustic cleaner was powered via a solenoid/timer by compressed nitrogen to avoid oxygen contaminating the product, which activated the titanium diaphragm to create the correct sound frequency.
The timer was set to sound the acoustic cleaner for a few seconds at periodic intervals during either filling or discharging from the silo.
The positive effect of sounding the acoustic cleaner was immediate with emptying of the silo on every occasion.
Material build up was eliminated, as was cross contamination.
The savings made from reducing downtime and product losses have more than paid for the acoustic cleaner.
