ABSTRACT:
In construction of a stonework crusher utilizing thermal deformation of shape memory alloy, heating means is coupled to one or more insert heads made of shape memory alloy without leaving any space there between so that thermal deformation of the insert heads should pose no substantial influence upon heat transmission from the heating means. In particular when several crushers are used in combination, uniform heat transmission at different crushers allows concerted generation of crush force by the combined crushers for effective and efficient crushing of stoneworks.
