Apparatus for milling building blocks at opposite first and second sides in two steps, comprising in combination:
- first means for milling said blocks at said first side thereof in a first one of said steps;
- second means for milling said blocks at said second side thereof in the second one of said two steps;
- third means located between said first and second means for accelerating said blocks in a direction of transportation of the blocks after said milling at said first side;
- and
- fourth means located between one of said first and second means and said third means for turning said blocks by 180.degree. for said milling at a second side thereof;
- said fourth means including a box having opposite open ends, with one open end providing an entrance for blocks and the other open end an exit for the blocks, and means including a frame for mounting the box for rotation by said 180.degree. about an axis of rotation parallel to said direction of transportation of the blocks.
