Gravity Separators are used to separate products of the same size but with a difference in specific weight. They can be used effectively to remove partially eaten, immature and broken seeds to ensure maximum quality of the final product. They may be used to separate and standardize coffee, peanuts, corn, peas, rice, wheat, sesame, and other food grains.

How it works ?

These Gravity Separators have a rectangular deck so that the product travels a longer distance resulting in cleaner separation of light and heavy particles and the lowest percentage of middlings.

The product flows over the vibrating deck in which pressurized air is forced through causing the material to stratify according to its specific weight. The heavier particles travel to the higher level and the lighter particles travel to the lower level of the deck.

In order to obtain efficient separation by specific weight, the pressurized air supply needs to be accurately adjusted and this is accomplished by having individually adjustable air fans to control the volume of air distribution at different areas of the vibrating deck. The table inclination, speed of eccentric motion and the feed rate can be precisely adjusted with ease and minimum of operator training.

Features

• Can easily separate granular materials according to the weight of the product.
• Easy deck removal for cleaning.
• Multi-fan system for accurate control of air.
• Precise Control of air, feed rate and speed of deck motion.
• Easy adjustment of deck inclination in both longitudinal and transverse directions.

Vibro-Cleaners are used for removing large impurities such as stick, buck and leaves as well as small impurities such as fine dirt and sand from good product in seed cleaning and processing plants for cleaning of all kinds of crops such as grain, seeds, corn, wheat, rye, soybeans, oats, millet and paddy etc.

How it works ?

They are provided with two vibrating screens, the top screen removes oversize material while the bottom screen eliminates fine dirt and sand. The vibration of the deck containing the screens is provided by means of unbalanced vibratory motors mounted in the center of the machine. The vibrating deck is mounted on four flexible multi-element springs, thus ensuring that there is minimum or negligible transfer of vibration from the vibrating deck to the machine structure.

The deck inclination, stroke and angle of throw are adjustable for optimum performance. Automatic Screen cleaning is provided by means of the Rubber ball tray system that ensures consistent and effective cleaning of the screens. The Screens are easily removable and the machine is provided with a swing down type door for easy access and change or cleaning of screens.

The machine has a highly efficient Aspiration System that includes Hopper aspiration for pre-screening aspiration as well as outlet aspiration for post screening aspiration. The Aspiration system which is easily adjustable provides an Air Wash of the product in order to rid it of dust, loose husk and fibres.
