The DENSIMETRIC TABLE is a machine used in the cleaning sections of cereals or other grainy products or semi-finished products such as legumes, coffee, shattered corn etc. It is essentially used to separate the product into various fractions based on its specific weight. Therefore, the classification is by density. The heaviest fraction is often made of stones and heavy metals.
In the DENSIMETRIC TABLE the product, once inside the vibrating body, is held in suspension due to the combined effect of air depression created by the suction and vibrations of the inclined sliding surface. The product is thus divided by sliding towards the outputs, according to its density.
The heavier fractions will tend to move to the left while the light ones to the right: in the various discharges we will then have the product divided by its density. Therefore, the classification takes place by adjusting the suction air, the inclination of the sliding surface and the position of the product’s exhaust points. The sliding surface consists of a particular metal mesh that holds the product inside but allows the necessary airflow to pass through. The vibrations are created by the movement of a pair of motovibrators.
Besides dividing the product, the depression and the airflow inside the machine remove the lighter impurities (straws, cereal film etc.) as well.
The machine therefore consists of:
- the basic structure, attached to the floor, which supports the vibrating part, the entrance and the suction;
- the vibrating part, with the worktop inside, moved by two motovibrators;
- the power drawer, equipped with an adjustment valve with spring contrast;
- the suction socket, with throttle with micrometric regulation.
