Frequently Asked Questions

A vibro sifter separates dry powders and granules by particle size. It is used to remove oversize lumps and foreign matter, grade granules before compression or packing, and check-screen raw materials in pharmaceutical, food, chemical and cosmetic plants.

We build models with screen diameters of 12", 20", 24", 30", 36", 48", 60" and 72". Indicative outputs run from 25–100 kg/hour on the 12" model up to 200–1500 kg/hour on the 72" model, depending on the material.

Screens are available from 4 mesh to 300 mesh. The right mesh depends on the particle size you want to pass and the oversize you want to reject; our mesh size guide explains how to choose.

Yes. All contact parts and screens are made of SS 316, and the sieves are lead-free and silicone-sealed. This suits pharmaceutical and food applications where cleaning and corrosion resistance matter.

Yes. Machines are manufactured in Ahmedabad and dispatched to customers across India, including Maharashtra, Telangana and Himachal Pradesh. Freight and installation support are confirmed in each quotation.

Price depends on screen diameter, number of decks, mesh, motor type (standard or flameproof) and accessories such as vacuum transfer. Share your requirement through the quote form for an exact price; see also our article on factors that affect vibro sifter price.

A vibro sifter only separates particles by size; it does not reduce them. A multi mill breaks down oversize granules to a target size. In a granulation line the two are often used together. See vibro sifter vs multi mill.

The number of screens. A single deck gives two fractions (pass and reject). A double deck gives three and a triple deck gives four. See multi-deck vibro sifter.

Yes. Flameproof construction is available for areas handling solvents or combustible dust. See flameproof vibro sifter.

Yes. Inline loading with a vacuum transfer system is available as an option so sifted material can move directly to a bin or blender.

The design is intended for low-noise, high-speed operation. Noise in use depends on the material, the screen tension and the mounting; a correctly tensioned screen and secure clamps keep it quiet.

Screens are clamped between the frames. Releasing the clamps lets you lift off the top cover and frames, swap the screen and reassemble. Spare screens in other meshes can be ordered.

Vibro sifters are portable and need only a level floor and power supply. We provide guidance for first start-up and trial runs; on-site support terms are confirmed in the quotation.
