Applications :Horizontal peeler Centrifuges are successfully used in Food Stuff, Pharmaceutical, Plastic, Organic & Inorganic Chemicals Industry for separating solids from solid liquid slurry with 5 to 50% solids contents and particle size ranging from 2 microns to 10 mm. Products which are difficult to filter or decant can be easily separated using Peeler centrifuge.Peeler Centrifuge is Used for :AlumiAmino acids, benzoic acid, benzene, hexachloride, calcium hypo chloride hexachlorocyclohexane insulin, potassium bisulphate, sodium perborate, penicillin, sulphur, starch, etc.ProcessThe unique feature of Horizontal Peeler Centrifuge is the constant basket speed i.e. all operations like feeding, drying discharging etc. are carried out at full-basket-speed. The sequence of Operations can be (either semi or fully automatically) controlled by Electro-hydraulic control panel / PLC controllerTypical Process Cycle Feeding : The Suspension is fed from the Storage tank to the basket rotating at full operational speed Removal of mother liquor : Under the influence of the centrifugal force the Liquid is drained from the solids, through filter elements (usually filter cloth). The solids are collected as ‘cake’ in the basket. Washing :  If required, in order to remove the traces of mother liquor washing facility can be provided to thoroughly wash the solids during separation. Re-drying : After giving wash or other treatment solids are further allowed to dry. Discharging : Solids are ‘peeled’ off by means of full-basket-width scrapper and is discharged through chute in front cover of the machine or conveyed by discharged screw. Design Features Gas-tight up to 0.04 bar overpressure, or Labyrinth shaft seal Automatic heel cake adjustment Oil-lubricated bearings Solids discharge by chute or by screw conveyor Drive: electric motor and V-belts, or with hydraulic drive with variable or constant speed Automatic and manual operation with either microprocessor or pneumatic controller Explosion proofing and safety devices Separation of Drive area / Process area Removal of shaft from the rear Easy cloth changing Through wall construction Working Principle Batch operation Fixed or variable speed Feed controlled by filling valve Filling by gravity or pump Basket filling monitored by filling level controller Intensive cake washing is possible with a variety of fluids Cake removal by hydraulically powered scraper over full basket width Standard Machines : Contact parts in stainless steel / coated or contact parts with non-coatable parts in Hastelloy C Other materials on request.

Application :The Decanters / Solid Bowl Centrifuges are used for clarification (liquid / solid separations), dewatering and classification duties in various process industries.Typical Products Processed : Inorganic products: Aluminium hydroxide, barium sulphate, lead oxide,chromium oxide, ferrous hydroxide, magnesium hydroxide, titanium dioxide, zinc sulphate, etc. Organic products: Carboxymethylcellulose, caprolactam, dimethylterephthalate, terephthalic acid, phthalic acid, etc. Plastics: Carboxymethycellulose, caprolactam, dimethylterephthalate, terephthalic acid, phthalic acid, etc. Silicates: Asbestos, clay, etc. Cellulose: De-inking flotation concentrate Foodstuffs: Fishmeal, casein, whey, etc. Design Features : Simple, rugged construction Rotor comprising screw conveyor inside conical / cylindrical bowl Screw conveyor (single flight or multiple flights), with or without hard surfacing Solids discharge through collecting channel and hard-surfaced scrapers Drive by electric motor and V-belts with gear box for high strength and reliability Oil lubrication for gear box and greasing for bearings Overload protection device Vibration dampers Optional Gas-tight design with gas-sealed labyrinths Perbunan, viton or PTFE seals Pressure-tight design with glide ring seals for up to 10 bar Optional – Centralised lubrication System Operations : Separation takes place in Horizontal conical / cylindrical bowl with screw conveyor. The slurry is feed into the bowl through a stationery inlet tube and accelerated by specially design inlet distributor. Centrifugal force leads to instant sedimentation of the solids on the wall of bowl The conveyor, rotating in the same direction as bowl with differential speed, conveys the solids to conical end. The solids are lifted clear of the liquid and centrifugally dewatered before being discharged into the collecting channel. The clarified liquid flows into the housing through opening in cylindrical end of the bowl.

The Automatic Vertical Pressure Filter Ensures : Improvement in productivity Reduction in energy consumption Superior product Properties High Yield Emission avoidance Applications : Pharmaceuticals Food Processing Waste Processing Effluent Treatment Minerals Mineral Concentrates Chemical Processing Design Features : The horizontal plate design results in even distribution of slurry wash liquid and most effective air penetration with no risk of cake cracking. Resulting in consistent performance in terms of through put, i.e. higher productivity. Once downstream and upstream equipment integrated with optimized process parameters leading to highest quality products, with lowest moisture and yield. No operator required, eliminates exposure of operator to chemical & equipment. As the driest cake is produced of all filtration methods, Lower energy costs as it eliminates or reduces the requirement of dryers. Ultra filtration wash system eliminates plant effluent system. The machine can be built with features confirming to explosion proof standards. Based on service requirements non corrosive, corrosive or highly corrosive application, machine can be built with various stainless steels & high strength materials. Horizontal filters plates Diaphragm pressing for filtration and cake washing up to 16 bars. Air blow for final drying of solids (cake) Continuous filter cloth guarantying a positive cake discharge Cloth washing both side of cloth (front & back) PLC – controlled panel. Mode of Operation : FILTRATION : With the push of Button, Filter Plates close, closed chambers are formed. Pressurised pumping of slurry into all chambers simultaneously takes place. As filtrate permeates the filter cloth, cakes are formed. SQUEEZING: High Pressure water fills all chambers, inflates diaphragm, squeezing the already formed cakes with 4 to 5 times higher pressure than feed pressure. Tightly woven filter cloth allows for higher pressure and increases filter efficiency. CAKE WASH:As the plates are horizontal, wash liquid is evenly distributed for uniform cake washing. POST WASH SQUEEZING: High pressure water is pumped in simultaneously to all chambers, squeezing all the wash liquid through cakes with ‘Total displacement’ wash, thus achieving very high efficiency. AIR-BLOWING: Compressed air is blown through cakes in all chambers simultaneously through adjusting Pressure & duration of air, further minimizes the moisture. CAKE DISCHARGE & CLOTH WASHING: All filter plate packs open with advancement of filter cloth all solids are discharged automatically both sides of filter cloth is washed with high pressure water to clear the cloth sieves of any binding solids.
