Presenting pusher centrifuge with the following main features: solid liquid separation in continuous operation; simple in operation eleminating manual handling; no spillage, higher yields; higher throughout with compact machine; higher wash efficiency; low energy consumption per unit production; minimum floor space requirement; and low maintenance cast with simple maintenace methods. Other features: higher solid throughout with minimal residual moisture; easy rotor assembly, simpler dismantling and installation process; lower pusher pressures, and reduced axial pressure, low energy consumption; cylindrical basket, multistage machines are possible; compact structures, easy and low maintenance; and relatively thick cake formation, high wash efficiency can be achieved. Spectrum of application: common salt, metallic salts, nitrates, chlorates, sulphates, carbonates, perborates, phosphates, ammonium sulphate, etc; organics like ascorbic acid, cmc, cellulose acetaate, hexamine, hydroquinone, melamine, oxalic acid, dichlorobenzene, pesticides salicylic acid, sorbic acid, tpa, tobias acid, urea etc.
