What is Centrifugal Screening?
Centrifugal Screening refers to the process of screening through the targeted use of centrifugal force. It is mainly used for products which are difficult to screen and which would clog up the screen feeders in conventional screening plants. This applies in particular to fatty and oily products and products with very light bulk densities.
Definition of centrifugal force
The term centrifugal force, also known as centrifugal force, is caused by the inertia of bodies and occurs in circular and rotary motions. According to the principle of inertia, centrifugal force refers to the inertial resistance that a body opposes to the change of its direction of motion when following a curved path. In contrast, the centripetal force is the cause of the change in the direction of motion. Both forces are in dynamic equilibrium with each other.
The example at the merry-go-round:
When a child rides a chain carousel and the father watches him, the two observers (child and father) feel different forces. The father sees only the centripetal force, which forces the carousel seat and thus the child to follow a certain circular path. The child, on the other hand, feels the centrifugal force created by the circular motion.
Applications of Centrifugal Screening at Ebbecke Verfahrenstechnik
Vibratory/rotary screening machines are used for various tasks at Ebbecke Verfahrenstechnik. The range of applications covers contract grinding, contract screening, protective screening and other processes for tasks and products with special requirements.
In detail this includes
Functionality of the vibratory/rotary screening machine
The vibratory/rotary screening machine at Ebbecke Verfahrenstechnik enables contract screening and subsequent contract filling of products that are difficult to screen. By means of a wing rotating in sieve half shells, an eddy current bed is generated and by vibration superposition of the outer sieve cloths, a keeping free of the cloths is made possible. The vibration screening machine from Ebbecke Verfahrenstechnik operates continuously, dust-free and quietly. The tension screen can be easily removed after opening the holding device upwards.
Advantages of vibratory/rotary screening
Centrifugal Screening, i.e. the vibration/rotary screening process, ensures that foreign bodies and impurities are reliably removed from powders and liquids. This is the basic prerequisite for perfect quality of the end product. At the same time, the machines are designed to enable efficient production processes with low maintenance requirements.
