[0002] Hollow bricks are commonly used in non-load-bearing areas. The porosity is not less than 40%. Bricks with large holes and few holes are called hollow bricks. Hollow bricks are divided into cement hollow bricks, clay hollow bricks, and shale hollow bricks. Hollow bricks are the main wall materials commonly used in the construction industry. They are similar to red bricks. The common raw materials for hollow bricks are clay and cinder ash, and the raw materials usually need to be crushed.

[0003] Based on the above, the inventors found that most of the existing hollow brick production raw material crushing devices are open-type. Since a large amount of dust will be generated during the raw material processing, the dust will affect the processing environment. Therefore, in view of this, the existing structure is studied and improved to provide a hollow brick production raw material crushing device, in order to achieve a more practical purpose.
