Abstract

The invention discloses a vibrating screen box body with the side walls being provided with guard plates. The vibrating screen box body comprises a framework, a plurality of screening plates and the side plates, wherein the multiple screening plates and the side plates are installed inside the framework. Each screening plate is composed of a screening bar fixing plate which is fixed to the framework and screening bars which are connected with the screening bar fixing plate. The structure is simplified and the mass is made low. In the operating process, the vibrating screen box body is made ofa high-manganese alloy steel paramagnetic material formed by the alloying elements like Mn and Cr, the whole vibration resistance of a screen box is improved, and the service life of the screen box isprolonged. According to the vibrating screen box body, the guard plates are arranged inside the side plates, the internal shock resistance and abrasive resistance are improved, the service life of awhole flotation machine is prolonged, the maintenance and replacement frequency is lowered, and normal operation of the equipment cannot be greatly influenced.

Description

technical field [0001] The invention relates to a mine screen box, in particular to a vibrating screen box body with guard plates on the side walls. Background technique [0002] With the continuous development of the mineral processing field, the application of the vibrating screen as an important equipment in the mineral processing field is also increasing; however, the vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting t...
