FAQs:
  • What materials is the GPY Disc Filter designed to dewater?
    The GPY Disc Filter is primarily used for dewatering fine-grained materials such as 0~0.5mm flotation clean coal and tail coal. It is also suitable for solid-liquid separation in metallurgy, chemical industry, petroleum, and sewage treatment applications.
  • How does the disc filter achieve solid-liquid separation?
    The filtration process relies on a pressure difference created by a vacuum pump. This forms a particle filter cake on the filter cloth, removing the liquid phase. The cake then moves to a drying area to remove most water, followed by a blow-off area where compressed air dislodges the cake, which is finally discharged by a scraper.
  • What are the key advantages of the paddle-type agitator?
    The paddle-type agitator features a floating sealing stuffing box that allows the agitator shaft to float, ensuring an effective seal and making sealing parts easy to replace. This design enhances reliability and maintenance efficiency in dewatering operations.
  • What is the unloading rate of the GPY Disc Filter?
    The GPY Disc Filter achieves a high unloading rate of up to 90% through its combined use of instantaneous air blowing and a suspended scraper. This system also allows the scraper to swing with the filter disc, optimizing force distribution and reducing host load.
