Background

The machine-made sand is sand processed by the sand making machine and other accessory equipment, the finished product is more regular, and the sand can be processed into sand with different rules and sizes according to different process requirements, so that the daily requirement can be better met. The machine-made sand can be used for preparing qualified and applicable sand and stone only by professional equipment. The machine-made sand production line is formed by combining equipment such as a vibrating feeder, a jaw crusher, a sand making machine, a vibrating screen, a conveyer and the like. In the preparation process of machine-made sand, powder can be generated, if the powder is not screened in time, the content of the powder in the machine-made sand is too high, the preparation of concrete in the later period is influenced, and the too high powder can be adhered to a conveying belt to pollute the surface of the conveying belt, so that the powder is screened before entering the conveying belt.

Prior publication No. CN104646281B discloses a vibrating screen, comprising: a base having a horizontal support portion and a vertical support portion, the vertical support portion being located at both ends of the horizontal support portion; the horizontal damping mechanism is connected with the vertical supporting part of the base; the vertical supporting mechanism is connected with the horizontal supporting part of the base; the horizontal guide rail is connected with the vertical supporting part and the horizontal supporting part of the base through a horizontal damping mechanism and a vertical supporting mechanism respectively; the bracket is used for fixing the screen assembly and movably fixed on the horizontal guide rail through the sliding block; and the motor is arranged on the base, and a rotating shaft of the motor is connected with the sliding block through a crank connecting rod mechanism.
