Technical Field
The utility model relates to a construction equipment field specifically says, relates to a two-layer type building gravel and sand preliminary screening device.
Background
The building sand and stone has an irreplaceable function in the building engineering. Generally, only river sand can be applied to construction works. During the excavation process, a large amount of rocks are typically excavated along with the sand. Therefore, before the sand and stone are used, a sieve is used for sieving the sand and stone, and then the sand and stone are used again.
At present, sand screening is mainly carried out by means of a sieve. The sieve pores of the screen are certain, and two or three kinds of screens are needed to be used for separating the sand and the stone according to the particle size, so that a large amount of manpower and material resources are wasted due to repeated screening. This is a disadvantage of the prior art.
