Description
Parameter

  • GN Large Flip-Flow Vibrating Screen is mainly composed of box type exciter, main vibrating screen frame, floating screen frame, shear spring, damping spring, flexible polyurethane screen mesh, support and driving device. The running amplitude is linear. Flip-Flow Vibrating Screen adopts the principle of double mass near resonance, so that the floating screen frame has a large amplitude, and the screen surface can deliver the material with an acceleration of up to 50 G. It is widely used in dry screening of medium and fine-grained, wet, sticky and other difficult to screen materials. It is not easy to block holes and has high screening efficiency.

    Large Flip-Flow Vibrating Screen Features:

    Technical features and advantages:

    • The screen machine wallboard is not welded, and the plate is made of high-strength alloy steel plate with better impact toughness. The imported Huck rivets are used for hydraulic tension assembly. This advanced design makes the wallboard free of welding residual stress.
    • Through finite element analysis, optimize the structure and vibration parameters of the screen, avoid the natural frequencies of all levels of the screen, reduce the influence of resonance, and extend the service life of the whole machine.
    • The cross beam under the screen adopts rectangular tube design; The exciting beam box structure is designed with light weight, high strength and good toughness. The post welding heat treatment process of main components can effectively eliminate welding stress.
    • The amplitude of the floating screen frame can be adjusted by changing the number of shear springs.
    • High efficiency helical gear box type exciter, with super large exciting force, ultra-low noise, stable operation and long service life; The eccentric block is arranged outside the exciter box, so that the amplitude can be adjusted by changing the counterweight setting
    • The polyurethane screen mesh is installed by pressing, which is more convenient to replace. The elastic deformation of the screen mesh has the function of self-cleaning the mesh, and can effectively solve the problem of clogging of fine, wet and viscous materials.

    Working Principle of Flip-Flow Vibrating Screen

    • Flip-Flow Vibrating Screen adopts the principle of double mass near resonance; A single drive generates a double vibration.
    • The main vibrating screen frame is driven by the exciting force to perform basic vibration. The floating screen frame and the main vibrating screen frame are connected with the shear spring to perform relative movement in the near resonance state.
    • One end of the polyurethane screen mesh is fixed on the fixed beam and the other end is fixed on the floating beam. The relative movement of the fixed beam and the floating beam causes the screen to stretch and stretch continuously, which can transmit very high acceleration to the material, so that the material can be fully thrown up and layered.
    • The screen can transmit the acceleration of up to 50 G to the material, so that the material can be fully loosened and penetrated through the screen to complete the screening. During the screening process, the screen mesh will produce elastic deformation under the continuous deflection motion, and the wet and sticky materials will be thrown away from the screen surface.
