Máximo rendimiento en roca blanda

• The design of the 12 ft 6 in (3.8-m) cutting drum unit installed in the 220 SM 3.8 / 220 SMi 3.8 has been optimized for the mining of soft rock to ensure maximum productivity at minimum operating costs.
• The surface miner extracts natural resources at a cutting depth of up to 13.8 in (350 mm) and with an unconfined compressive strength of up to 35 MPa selectively.
• The compact 220 SM 3.8 / 220 SMi 3.8 is the ideal candidate for use in small-scale to largescale mining operations.
• Natural resources are extracted in a single, environmentally sustainable operation without drilling and blasting, yielding material of high quality.
• Windrowing enables the mined material to be deposited behind the machine in a continuous process.
