Drill Hammer

The valved type BR2 Drill Hammer was created to operate at low working air pressures while delivering great performance. These hammers are durable and dependable drilling tools due to their straightforward design, simplicity of maintenance, and minimal air consumption. When the air is turned off, the BR2 Drill Hammer has a positive fitting check valve to prevent the entry of groundwater debris.

Drilling method of Drill Hammer in soil layer

The drilling method of the pneumatic Drill Hammer in the soil layer: the impact compaction drilling method. Its mechanism is mainly to use the impact force generated by the pneumatic Drill Hammer to push the drill bit forward. At the same time, under the action of the rotary force, the drill bit is continuously rotated at a certain angle, and the blade teeth on the compacting DTH drilling bits will scrape the compacted soil layer into a very thin loose layer, reducing the frictional resistance at the tail of the DTH bit. In addition, when the hammer piston of the pneumatic Drill Hammer impacts the drill bit at high frequency, it also gives the DTH rock bit a certain vibration force, which causes the liquefaction of the soil layer and destroys the original structure of the soil layer. Under the joint action of impact force, rotation force and feed force, the soil particles are rearranged and combined to form a strong cohesive force and adsorption force.

Drilling method of Drill Hammer in pebble gravel layer

Pneumatic Drill Hammer drilling method in the gravel layer: the characteristic is to use compressed air to drive the Drill Hammer hammer to circulate clean water or mud to remove chips. The drilling efficiency is high, and it is not affected by the back pressure generated by the water pressure. It can carry out deep hole and large diameter drilling.

Hammer drilling in hard and bedrock formations

Pneumatic down-the-hole hammer drilling method in hard rock formation and bedrock formation: In this drilling method, the rock is broken into fine cuttings under the repeated strong impact of the cemented carbide teeth on the surface of the embedded drill bit, and the rock The cuttings are carried out of the drilling hole by the high-speed airflow excluded by the pneumatic impact DTH hammer.

Because each drilling project's geological conditions, rock types, and rock hardness are unique, as example, the drill bit used to drill soft rock has excellent drilling performance, but if the same bits are supplied to drill hard rock, they have high loss and a short lifespan, which seriously affects the drilling project. The LEANOMS solution of drilling consumables can only be provided prior to the commencement of the drilling project by LEANOMS through thorough communication with users, thorough information, and expert analysis.
