SBSH – 250MNA-32KP
The machine is applied for drilling blast holes of 250- 311mm in diameter in rock with hardness up to 20 units according to prof. Protodyakonov scale.
The frame-platform design of the drill provides reliability of the whole construction when the drill operates in a complex mining and geological environment.
The compressor unit of 50m3/min capacity enables the efficient operation of the drill tool and provides proper cleaning of the holes from the drill fines. Our drilling rigs of heavy type have successfully gone through operational testings at the iron ore quarries. The ore was drilled with rods of 290 mm in diameter, later the diameter was expanded to 311mm.
The results have shown high efficiency of the drill and advantages that a buyer can get as a result of the increased productivity like the reduced energy consumption during mining and reduction by 20% of the over-sized lumps if compared to the drilling rigs with rods of 250mm in diameter. All that will allow you to reduce expenses on crushing the over-sized rocks.
SBSH-250MNA-32KP for drilling holes of 311mm in diameter at iron ore mines can earn more for its owners and increase the mined material output from 1 long meter by 35-40% if compared to drills with rods of 250mm in diameter. The oversize yield is cut down by 20%, as the result, we have reduced expenses on crushing.
