Method for grinding

Abstract

A method for grinding structural components, such as stone or conrete columns or slabs. According to the invention, the structural components are set in motion in relation to each other with their surfaces in contact with each other, to create a grinding effect through the movement.

1 . A method especially for grinding structural components, such as columns, slabs, or similar made from, for example, stone or concrete, characterized in that the structural components ( 1 ,  3 ) are set in motion in relation to each other while in contact with each other, the contact surfaces being simultaneously ground, due to the contact.  
   
   
       2 . A method according to  claim 1 , characterized in that, in the case of columns ( 1 ), the columns ( 1 ) are set in rotation around their longitudinal axis, and made to grind against each other longitudinally.  
   
   
       3 . A method according to  claim 1 , characterized in that, in the case of slabs ( 3 ), the slabs ( 3 ) are set in motion linearly or non-linearly in relation to each other, to grind their opposing surfaces against each other.  
   
   
       4 . A method according to  claim 1 , characterized in that an abrasive substance, mixed with water or some other medium, is added to the method.  
   
   
       5 . A method according to  claim 1 , characterized in that the grinding pressure acting on the surface of the column or slab arises from the column or slab's own weight.  
   
   
       6 . A method according to  claim 1 , characterized in that the force acting between structural components ( 1 ,  3 ), is increased or reduced according to the desired grinding effect.  
   
   
       7 . A method according to  claim 1 , characterized in that devices, such as sprockets and chains, cylinders operated by a pressurized medium, or similar, are used in the method to impart kinetic energy to the structural components.
