Mining Picks

Today, we will introduce to you several mining picks that are mainly sold in the Chinese market.
Picks are mainly used in coal shearers and roadheaders. Some excavators and milling machines also use picks. Different environments and models require different types of picks. So what are the commonly used picks?

Roadheader pick

Roadheader picks are mainly used for roadway excavation in coal or semi-coal roadways and soft rock, and can also be used in tunnel construction such as railways, highways, and water conservancy projects. At present, roadheaders mainly use pick picks, which are generally brazed by alloy steel teeth and hard alloy cutter heads. Its performance depends on the material of the pool body, the performance of the cemented carbide and the quality of the brazed joint. The degree of wear of the pick depends mainly on the hardness and corrosiveness of the coal rock.
S series picks are used for roadheaders, including S100, S120, S135, S150, S160, S170, etc.

Rotary Excavator Picks

Rotary digging teeth are mainly suitable for various hard layers, sand, pebble and gravel layers, and hard frozen soil. Soft rock, medium-hard rock, hard rock, weakly weathered, medium-weathered rock and other high-strength formations.
Rotary drilling rigs have high performance requirements for cutting tools (rotary drilling tools, rotary digging picks and tooth holders) during construction, so rotary drilling picks and tooth holders must have good impact resistance and wear resistance performance.
Rotary digging tooth is a kind of construction machine used for hole forming in building foundation engineering. Rotary digging teeth are generally used in building foundation engineering for piling.
Common models of rotary digging teeth:
ß25mm rotary cutters: C21HD, C31HD, C31, C32, T1X, T11X, T19X.
ß38/30mm rotary teeth: TS30CX, TS31CX, TS32CX, TS35CX, TS30, TS31, TS32, TS35, C6, C7, C4, DS01, DS06, DS04, DS05, TS19C X, U47, U47HD, B47K19, B47K22,
ß22mm rotary teeth: SD02, SM01, SM02, SM03, SM04, SM07, SM08, SL04, SL07, SL02,etc.
ß19-20mm rotary teeth: C21F, C21FHD, RS17, RS14, RS16, C3R.
ß11-14mm rotary teeth: CM63, CM65, CM61,

Shearer Picks

Common models of coal picks: U82/U84/U85/U92/U94/U95/U170
Coal pick specifications: diameter is 30 mm and 35 mm
The characteristics of shearer picks: effectively resist the abrasive working environment, and do not generate high-temperature sparks during the working process (beneficial to the safe production of coal mines)
Even coal picks of the same type can be classified based on different characteristics. For example, the types of coal picks are: ordinary picks, wear-resistant picks, hard rock picks, non-sparking picks, superhard rock picks and sandstone picks.
The coal pick is the pick of the wear layer. Hard rock picks and super hard rock picks are picks used on hard rock formations. Sandstone picks are specially designed for the geological conditions of sandstone. Non-spark picks are picks made of flame-retardant materials. This kind of picks will not generate large-area sparks when used underground.

The above is the introduction of the functions and models of commonly used picks.
