Description

Technical Field

[0001] The invention relates to the technical field of cement transportation, in particular to dust reduction type transportation equipment for cement production. Background Art

[0002] Cement is a powdery, hydraulic inorganic gelling material. When mixed with water, it becomes a slurry. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. For a long time, it has been an important gelling material and is widely used in civil construction, water conservancy, national defense and other projects.

[0003] Cement will generate a lot of dust during transportation. This dust will not only pollute the environment but also cause harm to the human body. Therefore, a dust suppression device is needed to remove the dust. However, the existing dust suppression devices often use water mist spraying to reduce dust during use. This method consumes a lot of water resources and is difficult to recycle cement dust that comes into contact with water. It is a waste of water and cement resources. It has certain shortcomings and needs further improvement. Summary of the Invention
