It is also the important alloying element which is used to make stainless steel, high strength low ally steel (HSLA), aluminium manganese alloy and copper manganese alloy.

High Quality Electrolytic manganese metal is also the indispensable material which is applied to electrode, ferrite, permanent magnet alloy element and manganese salt which is used in many pharmaceutical chemical industries.

The vibration-absorbing alloy which is recently invented also need it.

Our down-the-hole (DTH) hammer is a new type of valveless hammer driven by compressed air. It is the ideal rock drilling tool with advantages of large impact energy, high penetration rate, long service life, good efficiency of drilling cuttings removal, easy operation, and reliable working performance.
They are suitable to use in:
1. Drilling blasting holes, drainage and ventilating holes, center holes of raising boring, deep blasting holes in traditional drilling and blasting method of raising, pipe holes and other deep holes in all of various strength rocks in open pit and underground mining.
2. Drilling holes in road cutting and other stone constructions (e. g. ports and hydroelectric station constructions, etc. ) .
3. Drilling water wells, exploratory boreholes and injected holes.
This hammer can work with dry dust collection and also with wet dust removal using mixture of air and water.

The secific DTH hammers as follow:
TS series----for deep hole and super deep hole drilling
TG series----for drying drilling
TH series----for wet drilling
All our Hammers can be easily adapted to accept different types of bit shanks as COP, BR, DHD, SD, XL QL, MACH, Halco and Mission by simply changing a few basic components. Several models are available in Heavy-Duty format to suit particularly arduous and abrasive drilling conditions More...
