Features:
• Keestrack - creators of "Scalper" type screeners. Over 30 years of manufacturing and improvement experience – reliable, proven solutions.
• The screener is prepared for heavy-duty work. The screening force (G force) is exceptional. Therefore, its weight is 10% higher.
• The screener is prepared for easy configuration changes (e.g., replacing perforated plates with finger ("grizzly type") screens, which consist of elements).
• "Heavy duty" apron feeder with hydraulically folding feed hopper walls; much longer service life than a belt feeder.
• High productivity – up to 350 t/h.
• Significantly longer tracks provide stability during relocation and operation.
• Two transport speeds;
• K4 can be moved while working.
• K4 has a walkway, which is especially necessary when screening construction waste. It allows for convenient inspection of screens, cleaning them, and removing wood or plastic.
