The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.

  • Due to the machine's working environment being prone to intense vibrations and impacts, constantly observe the dynamics of various parts during operation. If you detect abnormal noise or other irregularities, shut down the machine immediately for inspection and repair before resuming operation. If hydraulic system connectors leak or components become loose, shut down the machine for adjustment and tightening. After ensuring everything is normal, you can resume operation. Before completing each shift, lower the hydraulic hammer to the lowest position and retract all other hydraulic cylinders to their shortest length. If moving a distance, keep the mast leaning backward. For the machine's components, accessories, and electrical equipment, perform regular inspections, especially the connections in the wiring of the motor. During operation, there should be designated personnel for guidance. The guide and the operator should check signals with each other before work and cooperate closely. At the start, use a bell or other methods to signal and inform surrounding personnel to move away. The machine should start at a low speed and gradually accelerate to high speed.
