Product Details

Fast Speed abrasive rock Odex overburden drilling systems

Description:

A soon as the drilling starts, the reamer opens and enlarges the hole to drive the casing shoe and casing tube down.
When drilling in over-burden formation is done,Start reverse circulation to close the reamer, and then pull up the assembly through the casing tube.
The casing tube can be left in the hole, or can be pulled out by means of grout sealing material
Use the normal drilling tools to drill and achieve to the desired depth.

Applications:

Blast hole:When hard rock is mined, the method of blasting is required. It is used to punch holes in the rock and then fill them with explosives. Blasting.

Mining:Mining is divided into open mining and underground mining. They need to be drilled.

Feature Advantage:

1, The hard alloy tooth material adopts high wear-resisting formula, and the breaking rate is less than 2%.

2, the pants body is made of high-strength high-quality alloy steel. After advanced heat treatment process, the rate of broken pants is less than 1%.

3, using advanced CNC CNC machining and advanced alloy tooth assembly process, the tooth loss rate is less than 2%.
