Static crushing agent surpasses the ordinary crushing agent to achieve better results

 

In fact, this static crushing agent is a kind of inorganic compound mainly composed of calcium oxide after calcining at high temperature.Among them, some admixtures are added together to grind into some non-explosive crushing powder materials with high expansion performance.A brief introduction to the static crushing agent, this thing is with the increase of the expansion pressure, the rock will have a crushing process.There is a crack in the process, and there is growth, and the opening is growing.This is the difference between the mechanism of rock breaking by static crushing agents and by ordinary explosives.You can assume that you have a hole in an infinitely large elastomer, the radius of the hole and the pressure applied between the walls.And the radial tensile force at any radius at this time and a stress in the tangential stretch.In fact, when the tensile stress exceeds the tensile strength of the broken body, the broken body will crack and finally become broken.

The compressive stress caused by the expansion pressure of the crushing agent and the tensile stress generated by the vertical direction act not only on the periphery of the hole to produce cracks.Of course, the expansion pressure of the crushing agent will continue after the crack appears.So the cracks have been developing continuously.This creates new cracks all the time, of course four or so in a single hole.Static crushing agents are more suitable for use than other ordinary crushing agents, its strength is much stronger than other.Many more people choose static crushing agents than ordinary crushing agents.
