Bottom Discharge Centrifuge

Magtech Process Equipments Pvt Ltd highly trained & rich experience professionals engaged in offering Bottom Discharge Centrifuges. These are of the most modern design , of sturdy construction, provide rapid acceleration , low current consumption and powerful efficient braking. The Bottom Discharge Centrifuge Basket has Radial Ribs instead of a flat bottom plate. The gaps in the basket bottom facilitate the cake discharge on to the inertia plate and to the Bottom hopper. The inertia plate too has radial ribs and large openings that allow the discharged cake to fall into a hopper fitted below the inertia plate. The monitor casing is fitted with a Scrapping Arrangement (Also known as Plow) on which a knife is mounted in such a way that the cake inside the basket is peeled off when the knife is engaged. In this model the cake is filtered in the same manner as the other vertical models but the cake discharge is achieved by means of a Scraper Knife that plows into the cake. At this point the basket is in rotation at a preset low speed and the cake is peeled off the Basket surface. The filter bag in a Bottom Discharge Centrifuge is held in place by Tensioned Rings or by screws and the bags may also have backing cloth or mesh to impart structural rigidity to the bag so that the bag does not distort of collapse while the knife is being engaged. The small gap between the scraper and the Basket Shell results in a thin layer of cake remaining inside the Basket. This layer is known as the Residual Heel. A Blow Off arrangement is provided to remove this Heel. Typically this is achieved by a blast of Air/ Nitrogen from specially arranged Air Delivery nozzles mounted on a pipe. The pipe is aligned with the basket perforations so that when the blast of Air is sent in to the pipe it travels through the Basket perforations and dislodges the Residual Heel. The Residual Heel Pipe can be swiveled during filtration such that the filtrate does not enter the nozzles and clog them. They swivel into position only during the scrapping cycle. In cases where Dual Action Scraper is used we can also provide flat Air Nozzles from the inside of the basket in addition to the Heel Pipe outside. The action of the scraper knife is by means of a Hydraulic Cylinder which is powered by a Hydraulic Power Pack.
