4-Shaft Shredders<\/h2><\/div>

Electric or hydraulic drive \u2014 30 to 320 kW<\/h3><\/div><\/div><\/div><\/div>

Satrindtech 4-shaft shredders<\/strong> represent the most advanced technology in our range for output particle size control<\/strong>. Four counter-rotating shafts<\/strong>, arranged on two overlapping planes, work in sequence: the two upper shafts perform pre-shredding of the material, while the two lower shafts complete the reduction, ensuring extremely uniform and consistent output. This dual-stage shredding process eliminates the need for sizing screens<\/strong> and minimizes dust production, thanks to the low shaft speed. <\/p>\n

Four-shaft technology is the ideal choice for applications requiring 24\/7 operational continuity with consistent output: WEEE, medical waste, municipal solid waste, plastics, and industrial waste. The range covers power ratings from 30 to 320 kW with working chambers up to 1960\u00d71690 mm, available in electric version for compact sizes (4S series) and hydraulic for large-capacity machines (4R series).<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Applications \/ Materials<\/h3><\/div>

The dual pair of counter-rotating shafts ensures uniform output regardless of input material heterogeneity, making it the reference technology for waste treatment plants requiring quality and continuity.<\/p>\n<\/div><\/div><\/div>
