Getech - Centrifuge System
The heart of the Gennaretti centrifuge is constituted by the main structure, which gives it an unmistakeable appearance and strength and solidity through time, unique in this sector: the machine body is manufactured in heavy moulding of spheroidal cast iron.
The discharges for the solid and the liquid are cast in stainless steel. Each of these components is guaranteed for life as each cast part is stable through time and allows great compactness, synonymous with high reliability for parts subjected to high rotational speeds. Thanks to this solid construction, even after many years of continuous operation, it is possible to regenerate the Gennaretti centrifuge: the cast parts are revamped and the electronic and mechanical components are updated to current standards. This is a great advantage for the user, who is not forced to sustain the cost of the purchase of a new centrifuge and change his plant completely. With a much lower and affordable investment, he can continue to use his centrifuge for many years to come, with the guarantee of a manufacturer that focuses on service and long life of his product.
The purpose of a Gennaretti centrifuge is a mutual investment, both for the customer and for Getech.
If a liquid solution is taken that contains suspended solid particles, and it is put inside a container, these undergo a sedimentation process due to the force of gravity (or G force), which tends to separate the components with different specific weight, obviously taking the heavier ones to the bottom. This process usually takes a long time and some particles can even take years to deposit.
If, instead, the same container is taken and rotated quickly, the solution is subjected to an artificial force of gravity; thus accelerating the sedimentation times and consequently separation.
zoomThe principle on which the operation of our centrifuge systems is based is that of taking advantage of the different specific weights of the substances that must be separated. Separation takes place inside a cylindrical-conical container, called drum, which is made to rotate at high speed by an electric motor in order to increase the force of gravity thousands of times. The product is fed into the centrifuge through a pipe; the rotation makes the solid deposit on the inner walls while the liquid forms an inner ring, whose thickness is determined by the position of the outlet level, through which a clarified liquid exits.
The auger is found inside the drum; its function is to transport the solid product towards the outside, which will then be discharged by an evacuation system.
The use of natural or chemical additives is made necessary for the separation of some types of solids, which facilitate said process.
