     Description


    NEWDIMOND hammers Widely used in geotechnical engineering to wear all kinds of hard in the hard, hard and other hard to drill tough rock. The low-pressure impactor is a valve type central exhaust impactor. The effect of discharging the rock powder is good, the repeated crushing of the rock slag is reduced, the wear of the drill bit is reduced, the drilling efficiency is improved, and the interior of the impactor is designed by using a new rock drilling theory. The size of the structure makes the impactor get the ideal energy transmission, with a single impact power, faster rock-drilling speed, and lower air consumption; using high-quality raw materials and advanced processing technology, the performance is more stable and the service life is longer. Disassembly easy, low failure, easy maintenance. Suitable for mining, quarry, road and other projects drilling blasting holes, landslide protection, dam reinforcement, anchoring and other engineering holes, geothermal air-conditioning, hydrology, water wells and other fields.

     

    1, using the latest contemporary rock drilling theory design of the internal structure of the impactor, the impactor to obtain the best energy transfer, drilling speed, low consumption of air.
    2, using high-quality raw materials and advanced processing technology, stable performance and long life.
    3, using a simple and reliable and easy assembly and disassembly of the internal structure, easy maintenance.

     

    Applications



    Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
