Description

Technical Field

[0001] The invention relates to the field of pavement material processing devices, in particular to a screening device for fly ash particles used for pavement materials. Background Art

[0002] The road surface is a layered structure made of various materials paved on the roadbed for vehicles to travel. Although vehicles can travel on the unpaved roadbed, its ability to resist natural factors and vehicle loads is very poor. It is dusty when it is sunny and muddy when it rains. When driving, the surface will be bumpy and uneven, causing vehicles to bump and slip, driving speed is low, or even unable to pass, and serious consumption of fuel and parts. After the road surface is paved, the road conditions are improved, which can make vehicles pass all-weather, and cars can travel on the road at a certain speed, safely, comfortably and economically.

[0003] Fly ash is one of the commonly used raw materials in the production of bricks. It can effectively improve the strength and durability of bricks.
