Knowing that you are interested in horizontal froth pumps, we have listed articles on similar topics on the website for your convenience. As a professional manufacturer, we hope that this news can help you. If you are interested in learning more about the product, please feel free to contact us.
As with almost all aspects of the froth pump, the intake duct should be as large as possible to facilitate the cleaning movement of the air and prevent clogging. They should be sloped towards the pump to allow air escaping from the slurry to travel back up to the suction line and into the sump where it can eventually escape. Otherwise, air will become trapped in the piping and interfere with the flow of the slurry to the pump.
Mineral froths are generally divided into large bubbles that are easily broken and very small tenacious bubbles that are difficult to separate from the slurry liquid. As ore grades declined everywhere, the flotation of the minerals produced increasingly tenacious froths, which caused pumping difficulties for operations. Grinding out more and more fines and ultrafine results in smaller bubbles froth. And a flocculant is added to the slurry to lock the air into more tenacious bubbles. Operators can use best practice design to design a more appropriate froth pump circuit or reduce flocculant of fines. MUYUAN pump industry CO., LTD. has a long history with froth pumping and its specialist engineers can help you resolve issues in your flotation circuit. To find out more, please contact us.
The biggest issue with pumping slurry is that air centrifuge into the centre of the froth pump, the eye of the impeller. Air will prevent the slurry from passing the froth pump. Excessive slurry forces air through the pump, which can cause significant strain loads on the froth pump's bearings as they pass, as well as on the froth pump's impeller and shaft, reducing their wear life.
Muyuan vertical froth pump is mainly used for conveys highly corrosive froth slurries, ideal for mining processing plants, flotation froth circuits, pulp and paper, sewage and effluent applications. Foam pumps work by avoiding pumping air and separating as much air as possible from the slurry before it reaches the pump impeller.
The froth pump range is ideal for mining processing plants, flotation foam circuits, pulp and paper, sewage and sewage applications. Foaming and viscous slurries are handled efficiently and without the problems typically associated with pumping high viscosity products.
