Sreenex Machines Pvt Ltd manufacturers Spheroidizer Mill. Sreenex Spheroidizer The extrudes from the extruder are converted into spherical beads by the centrifugal force created by the high speed rotation of the Spher'Odiser plate. Each extrudate that comes in contact with the chequered plate is broken in length to slightly more than its own diameter due to the speed of impact and the sharp edges on the chequered plate. These shortened rods and then converted into spheres through repeated impacts with plate, wall and other granules. There is a gap between the chequered plate and drum inner walls which is kept to a minimum through light concentricity requirements in manufacturing to avoid powders from falling down & beads being crushed during the Spher'Odization process. The RPM of Spher'Odization, choice of the correct plate and proper formulation are the key factors to the formation of good spheres with a high yield. A compressed air or inert gas connection is provided to facilitate rope of formation and to avoid pellet breakage. The Spher'Odizer consists of a round disc mounted on a vertical shaft spinning at high speed at the bottom of a cylindrical chamber or drum. The cylindrical drum is called the bowl and the spinning disc is called the chequered plate. The chequered plate has a grooved pattern to increase the friction with the product and to break the extrudates to length. When the extrudates are charged into the Spher'Odizer, they are thrown the edge of the spinning plate by centrifugal forces. By contact with the plate the extrudates are cut into short cylindrical segments, which are rounded by collisions with the drum wall, plate and each other. The fines generated during the process of Spher'Odization are compressed into the surfaces of the spheres. After the particles have obtained the desired spherical shape they are discharged via centrifugal force through an opening in the bowl wall. The action of particles colliding with the wall and each other and being thrown back to the inside of the plate creates a rope movement of the product along the wall. The continuous collision of granules with the wall and the chequered plate during Spher'Odization is essential for optimum results.
