With the economy developing and information technology improving, the construction industry has developed quickly. Therefore, the construction materials are in urgent need of during the construction process. However, the construction material has different sizes and specifications. This requires further screening of them. The invention provides a kind of vibratory separator for building construction. However, due to the traditional vibration screen unreasonable structure design, badly screening effect, easy to blog the mesh, which not only reduces the efficiency of the work but also makes the work cost greatly increased. To overcome the defects of the above existing technology, a kind of building material vibratory separator rotary be provided.

A screening building aggregate vibratory separator is composed of a base and set on the base of sieve chamber. It also includes the mixing chamber, described in the mixing chamber cross-section for the circular structure of exposure, the mixing chamber set headed with inlet, mixing interior ministry set stirring impeller, sieving part installed parallel two-layer filter sieve, filter sieve meshes from top to bottom in turn. The extension end of one side of the filter screen is connected to the compression spring, and one side of the outer wall of the screening part is connected to the aggregate box on the base through the receiving tube. The features of screening building aggregate vibratory separator are that vibratory separator is consists of vibrating motor, rear stabilizer and springs. According to the specific requirements, an air hummer can be installed on the mixer chamber.
The vibratory separator has the advantages of reasonable structure, convenient operation and high production efficiency. By setting the mixing chamber, it can be as the sand particles is to filter the preliminary separation, facilitate further screening of multilayer hon screen design can improve the quality of screening: by setting the compression spring, makes the filter screen in the vibration motor can be driven by relative reciprocating movement of a small scale, will stick on the screen gravel particles loose decomposition, which is not easy to plug hole, improve the efficiency of screening.
The input end of the impeller is connected to the driving motor. When the material enters the mixing chamber, the gravel particles to be screened can be stirred for preliminary separation to facilitate the screening in the next step. When the material enters the filter screen set in the screening chamber, the meshes of the filter screen decreases successively from top to bottom, thus the material is screened. One side of the filter screen is connected to the compression spring. Through the compression spring, the filter screen can move in a small range under the drive of the vibration motor. The electric control switch is also set on the base, and rollers are set on both sides of the base to facilitate the movement and transportation of the whole device. Through the cooperation between the stabilizer bar, the strong spring, the vibration motor and the sleeve, the stability of the entire transmission can be greatly improved, the service life can be prolonged, and the screening rate of the vibratory separator can be reduced due to the large longitudinal runout. An air hammer is arranged on the outer wall of the mixing chamber. By beating the air hammer, small sand and stone particles adhering to the screen and the inner wall of the device can be shaken off quickly.
