Description

Technical Field

[0001] This utility model relates to the technical field of casting sand mixers, specifically a casting sand mixer with easily adjustable discharge flow rate. Background Technology

[0002] A sand mixer is a device that uniformly mixes the components in molding sand and effectively coats the sand particles with binder. It is the main equipment for casting sand processing and molding sand mixing, and a key device for obtaining qualified molding sand. The sand mixer uses the relative movement of the grinding wheel and the grinding disc to crush the material placed between them through a grinding and crushing action. The sand mixer also mixes the material while crushing it. It is an ideal device for producing non-fired bricks, sand-lime bricks, cement bricks, refractory bricks, and for crushing and mixing fly ash, boiler slag, tailings slag, and industrial waste as raw materials for brick making.

[0003] Traditional roller-type sand mixers typically discharge the mixed molding sand directly from the machine body through the discharge pipe after mixing. However, existing sand mixers cannot close the discharge hopper or control the discharge speed, which reduces the effectiveness of the sand mixer. Utility Model Content
