Function

The movement of a tumbler screening machine is usually compared with simple hand screening similar to the “gold washing pan”. The product is continuously fed into the center of the top screen, from where it spreads out evenly to the outside across the entire screening surface. The finer particles fall through the screen near the center and the coarser ones successively towards the periphery. The material is moved in a spiral pattern with increasing acceleration of the particles the further they are from the center, with the result that even those particles, which are almost the same size as the screen mesh, are screened.

All the separated fractions are discharged through the lateral outlets. The screening process is repeated again and again on each deck. The heart of the tumbler-screening machine is the patented 3D adjustment system for setting the individual retention time of any product to be screened. The main shaft is driven by V-belts and an electric motor. Using a special axially spring-mounted graphic recorder, this 3D movement of the machine can be drawn on paper two dimensionally in the form of an ellipse and then measured exactly. The measured data can be transmitted at any time for further checking. In this way, optimum settings will always be available and reproducible in the future too.

With fine products in particular, the screen mesh openings tend to clog up and it is imperative that this be avoided if continuous operation is to be guaranteed. Various very effective screen cleaners are available for this purpose. The modular design enables different setup variations. The product can be re-screened 2 to 3 times to increase yield and screening efficiency. Other possibilities are integrated control screens or reversed screening with which the finest dust is separated first followed subsequently by coarser separations.

  • Favorable prices and short delivery times.

Function:

The machine is driven by a vibration motor attached directly to the center below the screen body. The screen body can vibrate freely and three dimensionally by means of dislocation via precisely adjusted springs. The difference between this model and the KTS tumbler screening machines is the acceleration, which is 3-4 times higher at a comparatively low amplitude. Because the amplitude gets smaller towards the top with each additional screen deck, only 3 decks can be installed per machine.

The centrifugal force of the motor can be altered, as can the offset angle between the upper and lower flyweight in order to adjust the retention time of the product on the screens. The screen frames are equipped with 2 grooves and 2 fixation rings which enable easy and fast re-meshing on-site without much experience or any special tools, particularly where fine-mesh fabrics are involved. The KTS-V sizes 900-1500 can also be produced with the body parts of the KTS tumbler screening machines in order to satisfy the demands of certain food and pharmaceutical products, for example.
