Description

A gravel processing and screening device

technical field

The utility model relates to the technical field of sand and stone screening, in particular to a sand and stone processing and screening device.

Background technique

Because of its good hardness and stable chemical properties, sand and gravel are widely used in the fields of houses, roads, highways, railways, engineering and other fields as high-quality building materials and concrete raw materials. Different sand and gravel structures vary greatly, and some particles are uniform in thickness , and some of different sizes, sand and gravel need to be screened during the construction process.

For example, Chinese patent CN217664453U discloses a sand and gravel screening device for producing concrete. The sand and gravel screening device for producing concrete, through the symmetrical setting of the screening device, makes the sand and gravel screening more meticulous, Uniformity saves the time and energy of manual removal, and it is more convenient to operate. At the same time, it reduces the dust in the air, reduces the pollution of the environment in the air, ensures the working environment of the operator, and makes the working environment safer.

In the comparison case, the sand and gravel are screened twice with different mesh sizes to achieve the screening effect, but this screening method is likely to cause the sand and gravel to accumulate together, and the sand and gravel located above cannot be screened, affecting Screening effect. At the same time of sieving the sand and gravel, it is atomized and dust-reduced, which reduces the dust in the air and reduces the pollution of the environment in the air. However, this method cannot handle the dust generated during feeding and discharging. , there will still be a lot of dust.
