VERTICAL DRY TYPE SAND PRODUCING APPARATUS AND METHOD

摘要

The present invention relates to a vertical dry type apparatus for manufacturing coarse and fine aggregates and a method thereof, and an objective of the present invention is to manufacture a mixture of coarse aggregate and fine aggregate (sand) through striking and grinding (and sort the coarse and fine aggregates through the following process to manufacture final fine aggregate), and use all portions of a liner so as to extend a life of the apparatus and increase productivity of the coarse aggregate. According to the present invention, the vertical dry type apparatus for manufacturing coarse and fine aggregates comprises a cylindrical case (10) having an inner circumferential surface lined with a liner, and a vertical crusher (20) rotationally mounted in the case and processing an object to be crushed inserted into the case while being rotated in one direction through a driving means to manufacture a mixture of the coarse and fine aggregates. The case comprises an inlet (11) and an outlet (12) formed on upper and lower parts, respectively, and the inlet and the outlet are formed at start and end positions in the rotational direction of the vertical crusher, respectively. The vertical crusher crushes the object to be crushed supported to the liner of the case while moving the object to be crushed inputted through the inlet of the case so as to discharge the crushed object to the outlet, thereby using all liners of the case.
