５が摩耗することはない。 Next, when the wire mesh conveyor 5 is driven, the product to be polished placed on the conveyor 5 enters the cleaning chamber 2 and reaches above the second impeller 8. The second impeller 8 is interlocked with the wire mesh conveyor 5,
The projectile material stored in the bottom of the grinding chamber 2 is sucked in from the lower end of the suction pipe 9, passes through the mesh of the wire mesh conveyor 5 from the projection port of the second impeller 8, and is used to release the products placed on the conveyor 5. It is projected onto the back side to remove burrs from the product. Note that the wire mesh conveyor 5 does not wear out because the shot material used here is a soft shot material such as walnut shell, apricot kernel, or nylon cut wire.

ムーズに保たれる。 When the back side of the product is polished as described above,
The product is lifted upward by the projecting force of the projectile material, but it is held down by the belt conveyor 10 disposed above the wire mesh conveyor 5 and does not stand up.
There is no turning back. Further, the belt conveyor 10 is rotated in the direction of the exit in conjunction with the wire mesh conveyor 5, and the products are conveyed toward the exit while being pressed against the belt surface of the belt conveyor 10 even during polishing. The flow is always kept smooth.
