Product Profile of Pusher Centrifuge with Hydraulic Pusher Control

The Pusher Centrifuge with Hydraulic Pusher Control utilizes continuous filtration for the separation of suspended, fast draining, crystalline, granular or fibrous solids from the liquid phase. Rotofilt Engineers Ltd. Manufactures Pusher Centrifuge with Hydraulic Pusher Control. Rotofilt Engineers Ltd. Is an ISO 9001:2000 certified company. In the Pusher Centrifuge, the solids can be washed as they are transported through the basket. Pusher centrifuges are used in all fields for the separation of slurries with solids which filter easily. The average particle size of the solids must be at least 0.1 mm.

Applications of Pusher Centrifuge with Hydraulic Pusher Control are:

• Chemicals: Glauber`s salt, boric acid, ascorbic acid, adipic acid, sodium chloride, iron sulphate, sodium sulphate, copper sulphate, sodium bichromate.

• Fertilizers: Ammonium sulphate, potash, urea, calcium nitrate, potassium sulphate.

• Plastics / Explosive: PVC, polystyrene, polyethylene, polypropylene, linters, nitrocellulose.

• Food stuff / Animal feeds: Extraction residues, meat pulp.

• Beneficiation: Rock phosphate, gypsum, ores, coal.

Design Features of Pusher Centrifuge with Hydraulic Pusher Control are:

• Mechanical unit:

- Sturdy welded construction of the bearing housing with incorporated oil pan and motor support.
- Vertically installed oil pump[s] which can be removed without draining of the oil.
- Hydraulic pusher control incorporated in the pusher piston.

• Process area:

- Solids collecting housing and volute race discharge.
- Identical housing for single and two-stage baskets.
- Feed pipe or feed screw.
- Various devices for the distribution of wash liquor.
- Wear protection package" available for abrasive products.
- Oil pressure joints for simple assembly and disassembly of the basket and pusher plate.

• Basket: The internal basket is available in several alloys. The basket shall is perforated with large filtration holes. Single and two-stage baskets in the long or short versions are available for optimum solution of the separation requirements.

• Slot Screens: The basket is fitted with a slot screen. The wedge bar profile and the slot width are chosen according to process requirements, i.E. Depending on particle size distribution and slurry concentration. The slot width is usually between 0.1 and 0.5 mm.

• Hydraulics and Pusher Action: The pusher plate [or inner basket for two stage units] is operated hydraulically. The spindle pump[s] vertically installed in the oil pan, supplies the required quantities of oil at up to 60 bar pressure. The reversing mechanism is integrated within the pusher piston. It consists of a hydraulically operated pre-control valve. Stroke length adjustment is available as standard.
