We are offering decanter solid bowl centrifuge based on the principle of sedimentation, the decanter solid bowl centrifuge uses the force developed under fast rotation of a helical screw conveyor which separates the liquid from the solid fraction at a slightly higher or lower speed than the bowl. Often the solids are too fine to be dewatered satisfactorily in the filtering centrifuges. They can be separated in solid bowl centrifuges provided their sedimentation speed in the mother liquid is sufficient. The sinking settling speed is determined by particle size, particle shape and difference in density between solids and liquids as well as their viscosity. In decanter centrifuges the cleaning of liquid takes place in cylindrical part where as dewatering of solids by compression of the filter cake takes place in conical part of the bowl. The geometry of the bowl, relation with length and diameter to be adapted to suit the application. In most of the cases, good results are obtained at length diameter 2 : 1 and sometime depending upon application 2.5 3 : 1. The system is continuous, compact and enclosed while offering versatility, high performance, and low maintenance.

We offer Vertical basket the Vertical Basket Centrifuge. Vertical Basket The Vertical Basket Centrifuge The Vertical Basket Centrifuge operates under a discontinuous filtration process and is well suited to the efficient separation of Pharmaceutical products and of fine and bulk chemicals. This type of centrifuge is used with small batch sizes and where products are changed frequently with low process costs, this enables versatile usage for processing numerous products with one centrifuge There is no crystal breakage, as the peeling is performed at the reduced speed. They can handle freely and none freely filtering slurries with equal facility. Rotofilt Vertical Basket centrifuges are built by making it easy to load from the top so that solids can then be extracted with knife or by hand. The equipment has been developed to operate the centrifuge with the exact same filter cake thickness as if it were a production size machine to enable gives a precise scale for each and every process from beginning to end. Rotofilt Vertical Basket Centrifuge is ideally suited of: Amino acids, benzoic acid, benzene, hexachloride, calcium hypo chloride hexachlorocyclohexane insulin, potassium bisulphate, sodium perborate, penicillin, sulphur, starch, etc.

We are offering automatic vertical pressure filter. Automatic vertical pressure filter is ultimate equipment designed to handle flammable, toxic and corrosive material since they are autoclaved and designed for hazardous environment when high pressure and safe environment is required. Likewise they may be readily jacketed for application whenever hot or cold temperature is to be preserved. Rotofilt automatic vertical pressure filter ensures the driest cake and high yield of the product with marked reduction of energy consumption. Rotofilt automatic pressure filter is a state –of –art equipment with proven technology and matches the features with the world-class manufacturers. This is evident from the repeat orders rotofilt receives today from india and abroad. Rotofilt prides with their indigenous fusion of intelligence and technology.

We offer Peeler Horizontal Peeler Centrifuge. Horizontal Peeler Centrifuge (Horizontal Discontinuous Separation) Peeler centrifuge operates on the principle of centrifugal force to separate solids from liquids by density difference. The high rotation speed provides high centrifugal force that allows the suspended solid in feed to settle on the inner surface of drum. The washing processes are performed at the same rotational speed and in same centrifuge vessel. The unique feature of Peeler Centrifuge Horizontal Peeler Centrifuge is the constant basket speed which allows all operations like feeding drying discharging to be carried out at full basket speed. Rotofilt Peeler centrifuges are offered both in the batch and continuous centrifuge processes. This process are determined to achieve maximum removal of solid from liquid that may be required to be as pure as possible and not be easily separated by differences their densities.

PUSHER CENTRIFUGE With simple robust design the Pusher Centrifuge gives high throughputs under the toughest conditions. Operates purely on with mechanical drive the Pusher Centrifuge is suited for all fields for the separation of slurries with solid which filters easily. The average particle size of the solids must be at least 0.1 mm. Pusher Centrifuge utilizes continuous Filtration for the suspended, fast draining, crystalline and granular or fibrous solids from the liquid phase. These solids can be washed as they are transported though the basket.
