CDGX Series

Gravity Separator by density (separates by weight)

The gravimetric separators from SABINA-AGROTUL separate grains according to their density by combining the effects of an upward air stream and the oscillations of its internal mechanism. This causes the denser grains to ascend to the top cover, separating them from the rest of the flow.

​

The gravimetric separator SABINA-AGROTUL separates grains or seeds based on their differences in density and size using an upward flow of air, mechanical agitation movement, and gravity effect. Initially, the mixture is separated into horizontal layers based on weight, and then these layers are directed towards different exits.

Features

Filtros de entrada aire.jpg

The gravity separator sucks air from the bottom. In the image, you can see the air inlet windows, equipped with filters to prevent - as much as possible - the entry of dust.

The heart of the unit is a steel-framed box that supports the vibratory system and the different screens on which the grain, seeds and other materials are being progressively separated in size as they crawl down the deck.

The units that include our proprietary vacuum system are equipped with a uniquely designed feed hopper that allows for the separation of empty husks, shells, and other light debris before the grain is fed onto the screen deck thus increasing the separation efficiency and delivering a much cleaner grain.The material that is suctioned off the flow of grain to a speed slightly inferior to the critical speed of seeds and healthy grain - mainly composed of hollow grain and shells- is accelerated through a circular shaped peripheral duct allowing the accumulation of these solids at an offset location. A sudden change in the cross-sectional shape of this duct force these solids to detach from the airflow, falling by gravity to a collector discharge chute.

Each screen deck is comprised of a screen frame, a wafer of screens adjusted on fasteners. Each screen wafers comes with special rubber balls that ensure the screen is not blocked with debris.

Heavy-duty knob locking mechanism with a safety kill switch that stops machine operation if the door is open.

The oscillatory movement is provided by a mechanical crankshaft and connecting rod system mounted on pillow bearings. This system is counterbalanced to reduce vibrations that flow out to the rest of the equipment.

Other Features

funcionamiento densimétrica.jpg

  • Two-rotor vacuum fan, with airflow control.  Inspection hatch allows the operator to inspect all inner mechanical elements and clean the unit.

  • Machine frame built of structural steel designed and fabricated to maximize machine stability and integrity while conveniently allowing swift access to inspection and maintenance on all parts.

  • Deck frame built on 2, 3 and 4 levels. The frame is lightweight to optimize oscillating performance while holding great strength. The frames are inserted through slide racks which are then latched and secured in all coordinated for proper operation. The change of screens can be performed in a matter of minutes!

  • The screens are installed over a frame with cross-sectional racks, which increases the rigidity of the screening surface, thus avoiding the commonly known concave deformations which are very detrimental to the performance of the machine and the quality of the product. The screens are fabricated in sections, which allows also to change specific high-wear areas more often than the others improving the operational cost of the unit.

  • Vibration mechanism is crankshaft-connecting rod style with counterweights. Everything is mounted on quality heavy duty bearings specifically designed for long life under the described operational environment.
