[0001] The utility model relates to the technical field of sand making machines, in particular to a dust-proof double-roller sand making machine. Background Art

[0002] Double-roller sand making machine, also known as double-roller sand making machine, is a device widely used in the medium and fine crushing of ores and rocks with medium hardness or below in industrial sectors such as sand making, mineral processing, cement, chemical, and building materials. By passing the rock or ore into the crushing chamber of the machine through the feed port, the material is subjected to the meshing force of the rotating rollers, so that the material is forced into the space between the two rollers, and at the same time is squeezed and sheared by the rollers, and the material is crushed.
