摘要

Provided is a sandmaking facility and a sandmaking method for waste stone that can be easily disposed of even if it is a large waste stone, and that can produce useful sand from waste stone. A facility 10 for producing sand 4 from waste stone material 1, which is composed of an incinerator 20 for incinerating the waste stone material 1 and a crushing device 20 for crushing the waste stone material 2 after incineration. By incinerating the waste stone material 1, the waste stone material 1 after incineration can be made brittle stone material 2 and made brittle. Therefore, by crushing the brittle stone material 2 by the crushing device 20, the sand 4 can be easily made. Therefore, even if it is a large waste stone material, it can be easily disposed of, and sand having a utility value can be made from the waste stone material.
