PROBLEM TO BE SOLVED: To provide an inexpensive apparatus for crushing cementitious solid matter capable of comparatively easily crushing lumps of the cementitious solid matter and facilitating classification, and capable of solving such problems that when recycling concrete waste by crushing into an appropriate size with a conventional crushing machine to use again for the similar purpose, a crushing machine is big, massive and expensive because an emphasis is placed on a crushing power for crushing stones and the like, that classification is difficult and crushed matter is hard to take out, and further that it has a small capacity because it is for crushing a comparatively hard matter. SOLUTION: The apparatus for crushing the cementitious slid matter comprises a hopper, a mesh cylindrical body and a receiver for crushed matters, the mesh cylindrical body having a driving device for revolving it and a revolving shaft therein which independently revolves, the revolving shaft having a large number of crushing blades attached thereon.
