PDC picks

PDC picks are widely used for hard tunneling excavation, coal mining (with coal gangue), complex geology, road milling, applied in construction of rotary drilling machines and dual milling equipment. When cutting coal rocks, picks will bear periodic high compressive stress, shear stress and impact load. At the same time, in such complicated conditions, due to friction and impact will cause pick temperature, the pick heads are required high wear resistance, good impact resistance, and excellent thermal stability. Compared with tungsten carbide inserts, PDC inserts have such excellent performances, and show higher cost efficiency advantage.

Technical Features

The pick body is made of molybdenum nickel alloy steel, with high strength, high hardenability, high toughness, small deformation, high temperature quenching. The pick steel use the special heat treatment, with high fatigue limit, high impact resistance, and good low-temperature impact toughness.

The pick head is PDC insert. Using HTHP process, the PDC head is with extremely wear resistance, excellent impact resistance and heat resistance, also with good heat conduction, corrosion resistance.

The combination of the pick head and pick body applies the cold setting process.

Compared with common alloy l picks, the advantages of PDC picks are:

Long service life

Reduce the quantity of the picks replacement.

Reduce the use cost of the picks

Improve mining/excavating efficiency

Improve the utilization rate of equipment

Improve the reliability of the operation and reduce the labor intensity of workers

 

PDC Coal Picks

 

Coal picks are the important parts of the coal mining machines for breaking rocks, and they are also one of the vulnerable parts of the coal mining machines. The performance of coal picks has a great influence on the production capacity of coal mining, the power consumption of coal mining machines, the work stability, the workers labor intensity, and the service life of other parts. Compared with common alloy coal picks, PDC coal picks have better wear resistance, longer service life, higher construction efficiency and higher cost efficiency, especially suitable for the hard rock formations

PDC Excavating Picks

Excavating picks are one of the most vulnerable parts of tunnel excavation, which are used with tunneling rock-broken machines. The performance of excavating picks has a great influence on the tunneling ability, the power consumption of tunneling excavating machines, the work stability, the workers labor intensity, and the service life of other parts. Compared with common alloy excavating picks, PDC excavating picks have better wear resistance, higher heat stability, longer service life, higher construction efficiency and higher cost efficiency, especially suitable for the hard rock formations with quartz rock.
