New rock drill developed

Doofor Inc has launched a new version of its rock drills.

The company has released new versions DF550-560-series, which it claims are the most powerful rock drills in its series, according to IM.

The DF560L-2m is a high frequency hydraulic rock drill deigned for production drilling on the surface, underground, and for tunnelling.

Constructed with two 160 cubic centimetre Danfoss OMS-series rotation motors as standard, the drifter provides 20kW percussion power, providing the torque needed for drilling in a range of different rocks, and can achieve maximum hole diameters of 89 millimetre in hard rocks such as granite, and even larger holes in softer rocks.

It has been designed with a low profile, with overheads of just 84 millimetres from the drill centre line.

This allows for close and deeper drilling up to the roof, and straighter, according to targeted lines.

The rock drill itself has a separated flushing head that allows operators to use different flushing media such as water, air, or air-water-mist.

Doofor has also created a new BLT-flushing head with enhanced properties. Made from stainless steel, it is designed for harsh mining environments, whilst the BLT-flushing head prevents water leaking inside the drill itself and causing damage.

The new model is adjustable with R38, T38, and T45 shank adapters, and if the BLT-flushing head is used female FR28 and FR32 shank adapters.

In terms of tap hole drilling, it can be equipped with heat resistant sealing.
