Rotajet Pre washers
The Rotajet PW prewashing washing machine is a screw auger washing system, generally the machine are used for removal of high loads of contamination prior to friction washing. The Rotajet PW plastic prewasher washer is fitted with a wash section is which wash liquid is sprayed at high pressure and flow, the resulting wash liquor impinges on the surface of the plastic being transferred up the incline conveyor. The impacted from the spray liquor removes surface dirt, grease, muck, dust etc…from the plastic. For more demanding cleaning applications a heated detergent solution can be used. The wash liquor and contamination drains down the incline screw into a vibratory sieve. The vibratory sieve filters the solution which is then pumped to storage tanks for reuse.
Heating can be fitted to the bulk storage tanks.
The Rotajet PW is manufactured from small system capable of 500 kilos per hour up to machines with throughput capacities of 6 tons per hour.
The Rotajet PW prewasher, is used for washing PET bottles, and HDPE bottles prior to wet granulation, to remove surface contamination. The prewashing increases blade life of wet granulation systems.
