Pre-treatment for Waste Washing
Pre-washer removes a large portion of contamination prior to friction washing and sink-float tank.
It is typically used for raffia, agricultural films and PET/HDPE containers. Prewasher works best with heavily contaminated materials.
Pre-washer for plastics is composed of a large auger, water infeed and high-torque motor.
Once the materials enter from the hopper, the auger pushes them forward. During this process, materials are scrubbed against screens and auger in the assistance of water. As a result, contaminants like soils, sands and gravels easily exit from the system.
Pre-washer is allowed to handle contaminated materials with a high percentage of metal parts or sands. Thus, pre-washer is generally used as a preliminary washing or primary treatment.
• Rails on auger prevents auger jams.
• Discharge soils, gravels, sands and small metal parts, minimizing wear and tear costs for your recycling system.
• Auto-reverse system re-orients shredder rotor’s direction when motor overload and material jam.
