    High Frequency Vibrating Screen Vibration Mode

    Linear motion Advantages: high vibration G force, high conductance, large processing capacity, direct effect on materials, large throw-vibration angle, short residence time on the screen surface, etc., suitable for feeding material with low viscosity, large flowrate, large solid content, large size and hard solid.

    Elliptical Motion Advantages: It has a gentle effect on the feeding material, the material stays on the screen surface for a longer time；The screen hole is not easy to be blocked, and the solid particle is not easy to be fragmented. It is suitable for feeding materials with high viscosity, small flowrate, large solid content, and easily broken solids.

    Part 2 Tandem Deck Vibrating Screen

    GN tandem deck vibrating screen is composed of two decks in tandem. The upper deck filters the coarse particles, and then the filtrate falls onto the lower deck for fine particles filtering. GN tandem deck vibrating screen can be used in both wet separation and dry separation. According to the characteristics of the feeding material, back weir box feeder, top hopper feeder, or top box feeder can be optional. The vibration motion of GN tandem deck vibrating screen can be adjusted based on the working conditions to realize linear motion or elliptical motion. Wedge wire screen panel, polyurethane screen panel or stainless steel wire mesh screen can be used to meet the screening requirements of different particle types of the feeding material.

    4 Tandem Deck Vibrating Screen

    TANDEM DECK VIBRATING SCREEN WORKFLOW DESCRIPTION: The tandem vibrating screen adopts upper-lower double-deck design, which realizes the feeding material to be screened from upper deck to lower deck in turn, the upper deck for coarse particles, and the lower for fine particles. After the feeding material passes through the upper coarse screen, it falls onto the lower screen for fine separation.

    TANDEM DECK VIBRATING SCREEN FEATURES

    1. Single unit tandem deck vibrating screen can achieve 2 levels of different particle screening.
    2. The upper coarse screen can protect the lower fine screen.
    3. The two-stage screening is completed in the same vibrating screen, which can reduce the coverage area and save the running cost.
    4. Name brand vibration motor is utilized with superior performance and reliable quality.
    5. High frequency vibration, linear and elliptical motions can be selected to meet different screening requirements.

    Part 3 Parallel Deck Vibrating Screen

    GN Parallel Deck Vibrating Screen is composed of upper and lower layers in parallel. Generally, the cut point of the upper screen and lower screen are the same. The upper and lower screens are feed separately. After screening and filtration, the liquid separately flow into the collecting box. GN parallel deck vibrating screen is used for wet separation, rather than dry separation. According to the characteristics of materials, weir type feeding hopper or top box feeding hopper can be selected for option. The vibration track of GN parallel deck vibrating screen can be adjusted according to the working conditions to realize linear motion or elliptical motion. The parallel deck vibrating screen is usually made of stainless steel wire mesh screen, which is used to screen out solid with size of 38 to 2000 microns in liquid-solid mixture.

    PARALLEL DECK VIBRATING SCREEN WORKFLOW DESCRIPTION

    Parallel design allows the feed flowing into the upper and lower screens with same cut point at the same time for separate vibration screening. After being screened by the upper screens, the filtrate falls into the buffer platter and then flows directly to the collection box at the base of the equipment. The filtrate coming from lower screen also flows to the collection box.

    PARALLEL DECK VIBRATING SCREEN FEATURES

    1. Single unit parallel deck vibrating screen is equivalent to two single deck vibrating screens installed side by side, which saves area and reduces cost.
    2. Drawer screen replacement mode allows screens to be replaced in a quick and convenient way.
    3. Deck angle can be adjusted according to treatment requirements.
    4. High frequency fine separation vibrating screen meets the solid-liquid separation requirement of ultrafine particles.
    5. Name brand vibration motor is utilized with superior performance and reliable quality.
