Type GF drum filter works with the general vacuum drum filter basically the same. The main difference is GF filter before the filter aid precoat. Filtering, channel body under the action of vacuum suction filter aid, the outer surface of the drum pre-coating of desired thickness, and then injected into the slurry to be filtered, under vacuum suction, the filtrate separated by precoat and filter cloth, by pipette, set the tube, the gas-liquid separator is discharged. The slurry of the solid particles are pre-coated retained, with the aid of automatic feed continuously scraped off the surface. When the pre-coating residual thickness of about 10mm, the need to re-precoating, the next work cycle. Product Features: 1, customized design, should customers' different needs. 2, the use of pre-coated technology, high clear filtrate. 3, automatic unloading. High filtration efficiency. 4, the drum can be designed to spray, material washing effect. 5, serialization process units, easy to install. 6, advanced and reasonable structure, beautiful appearance. 7, excellent production environment, simple operation, convenient, and effort.
