The pneumatic pick is a tool with compressed air as its power. The compressed air is distributing alternatively through the tube-shaped distributing valve into either end of the cylinder, so that the hammer is reciprocating motion in it, which impacts the tail-end of the pick rod and drives the pick rod into the rock or strata of mine, thus causing them to split into pieces.

I have learned about your company from the website. This is sara from sino-expansion co., ltd. Here i would like to take this opportunity to introduce our company and products(crackag) to you:
We are one of the largest manufacturers of non-explosive cracking agent(mortar)in china. Crackag is a kind of expansive chemical product, which is very popular in the international quarrying and demolishing market.
When it is mixed with clean and cold water to be mortar and poured into pre-drilling holes of rock and concrete, it swells and exerts expansive capabilities on the hole-wall at a unit value of more than 50mpa (500kg/cm2 .) which is strong enough to cut and crack reinforced concrete, marble and granite after a while.
Copmare to the traditional explosives, it has the following advantages:
1)non-explosive and very safe
2)very economical and cost-effective;
3)the shape is controllable
