Description: Tumbling Non-Vibrating Shaking Motion Separator Grader is used for solid-solid powder separation. The basic motion rotates with the horizontal motion that being similar to plant sifter. The eccentricity can vary from slow speed V-belt drive that allows variable speeds. The residence time of each product can be adjusted by the assembly in a radial and tangential angle, towards the drive axis. A three-dimensional tumbling motion, which is a mixture of plane and throw, is created. The screening material is uniformly distributed over the entire surface from the centre to the periphery. It will travel in a spiral transport direction. In the centre, the finer particles will pass through the mesh holes. Towards the outside, the horizontal and vertical acceleration increases, causing the particles with near mesh size to be separated. The remaining oversize is carried to the outlet where the flow is also controlled by an adjustable deflector. This deflector is another factor in controlling the residence time of a material on the screen. This process is repeated on every screen deck.. When fine screening is done, the screen meshes can become blinded by particles, dust or by static charges, which greatly reduces the capacity and the screening efficiency. For a continuous operation, it is necessary to have an appropriate anti-blinding system for the materials being screened. The circular design, with its central main shaft and three-dimensional motion, enables tumbler screening machines to utilize different anti-blinding systems like: ball cleaning, roller brush cleaning and air-jet cleaning.
