きる。EFFECTS OF THE INVENTION According to the present invention, a plurality of fan-shaped net grids are combined into a circular shape, and each fan-shaped net grid is continuously moved from the screening removal zone to the collection zone and further to the screening removal zone, and the powder particles are present in the screening removal zone. The body is dropped onto a fan-shaped mesh, large particles are left on the screen as a sieve material and removed, and the residue on the fan-shaped mesh is dropped by inclining or rotating the fan-shaped mesh vertically in the recovery zone. By virtue of this, large particles such as foreign substances can be continuously removed, and this can be discharged out of the system in the recovery zone. Further, by using this continuous processing screen in combination with a plurality of stages, it can be applied as a continuous classification processing device from a large object to a small object (for example, 20 mm to 5 mm mouth).

Unlike the case of using the mesh grid, there is no need to monitor or look around the mesh grid-shaped detention object, and unmanned operation is possible.
また、固定網格子の場合と異なり、網が摩擦等により
破損した場合にも、粒粉体の移送系を停止することなく
網の補修を行なうことができ、点検や保守管理も容易で
ある。Further, unlike the case of the fixed mesh grid, even when the mesh is damaged by friction or the like, the mesh can be repaired without stopping the granular powder transfer system, and inspection and maintenance management are easy.
