SMJRD19 secondary breaking drill rig

trituración secundaria versátil diseñada para reducir bloques grandes y mejorar el flujo de minerales en operaciones de minería masiva.

Split Mountain secondary breaking drill rig,SMJR19,is a robust,single telescopic boom,self-contained diesel-hydraulic jumbo rig, with on-board water tank and air compressor for air-mist flushing.This drill rig is engineered to optimize extraction rates and safely release blockages to improve drawpoint availability in back caving operations and narrow vein mining.Split Mountain secondary breaking drill increases productivity by breaking oversized boulders without the need for explosives and time-consuming ventilation and evacuation measures.A major benefit of this breaking method is a vibration-free working environment with low dust levels, since explosives are not needed. Remote control for our secondary breaking drill rig optional,to ensure a safe working environment for the operators. Split Mountain range of secondary breaking drills could include compact and flexible mining jumbos, longhole rigs as well as drill-charge and drill-split breaking units capable of fast, easy positioning and effective operations in confined spaces. The jumbo layout of the larger machines provides a well-protected work environment for maximum productivity, while the smallest rig offers the best accessibility and flexibility in confined spaces.
